NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE PERIODS ENDED SEPTEMBER 30, 2014 AND 2015

(Amounts in US$ thousands, except share and per share data)

(UNAUDITED)

1. Description of Business and Basis of Presentation

Description of Business

Solar Power, Inc. (“SPI”) and its subsidiaries (collectively the “Company”) is a provider of photovoltaic (“PV”) solutions for business, residential, government and utility customers and investors. The Company provides a full spectrum of engineering, procurement and construction services (“EPC”) to third party project developers, as well as develop, own and operate solar PV projects that sell electricity to the grid in multiple countries, including China, the U.S., the U.K., Panama, Greece, Japan and Italy.

Prior to 2014, the Company was primarily engaged in providing EPC services to developers in the U.S. Since 2014, the Company commenced its global project development business by ramping up its portfolio of global solar projects, including projects that the Company intends to hold in the long term and derive electricity generation revenue.

As of September 30, 2015, SPI’s major subsidiaries include Xinwei Solar Engineering and Construction (Suzhou) Co., Ltd. (“Xinwei Suzhou”), Xinyu Xinwei New Energy Co., Ltd. (“Xinyu Xinwei”), Sinsin Renewable Investment Limited (“Sinsin”), Gonghe County Xinte Photovoltaic Co., Ltd. (“Xinte”), SPI Renewables Energy (Luxembourg) Private Limited Company S.a.r.l. (formerly known as CECEP Solar Energy (Luxembourg) Private Limited Company (S.a.r.l.)), and Italsolar S.r.l, (collectively the “CECEP”), Solar Juice Pty Ltd (“Solar Juice”), SPI Energiebau Renewables GmbH (“SPI Energiebau”), SPI Energy Co., Ltd. (“SPI Energy”), Solarbao E-commerce (HK) Limited (“Solarbao E-commerce”), Jiangsu Solarbao Leasing Co., Ltd. (“Jiangsu Solarbao”), Yanhua Network Technology (Shanghai) Co., Ltd. (“Yanhua Network”), SPI Solar Japan G.K. and Solar Power Inc UK Service Limited. CECEP, Solar Juice were acquired by the Company in February and May 2015 respectively. CECEP owned and operated a number of PV plants in Italy. Solar Juice was engaged in the distribution of PV related products including solar panels in Australia. Refer to Note 4 for details of these acquisitions.

SPI Energy was incorporated by SPI as a wholly-owned subsidiary in the Cayman Islands in May 4, 2015. On May 11, 2015, SPI Energy initially filed a registration statement on Form F-4 in connection with seeking shareholder consent for the approval of certain agreements and plan of reorganization and related redomicile of SPI to the Cayman Islands. On November 5, 2015, SPI Energy filed registration statement amendment no. 5 on from F-4 in connection with such re-organization and related redomcile.

Solarbao E-commerce, Jiangsu Solarbao and Yanhua Network were incorporated by the Company in 2015 for raising funds from individual investors and leasing of solar panels through an online platform owned by Solar Energy E-Commerce (Shanghai) Limited (“Solar Energy”). Solar Energy was incorporated in China on December 8, 2014 by Xiaofeng Peng (“Mr. Peng”), Min Xiahou and Jing Liu, who are the chairman of the Company’s board of directors, deputy chairman of the Company’s board of directors and chief financial controller of the Company respectively. Solar Energy operates the “www.solarbao.com” e-commerce and investment platform which primarily targets retail customers residing in the PRC. On March 26, 2015, the Company, through Yanhua Network, entered into a series of contractual arrangements (“VIE Agreements”) with Solar Energy and its shareholders. The contractual arrangements include power of attorney, call option agreement, equity pledge agreement, and a consulting services agreement. As of the date of these condensed consolidated financial statements, the Company has not established the legal enforceability of these contractual agreements described above including the registration of the equity pledge agreement in the relevant government bureau in the PRC. Therefore, the financial results of Solar Energy could not be consolidated by the Company before the legal enforceability of the contractual agreements is established.

Through the on-line platform of Solar Energy, the Company has raised funds from individual investors, who need to register as a member on the platform, through certain on-line products launched by the Company since January 2015. Each on-line products launched on the platform are set with a targeted amount of funds in renminbi to be raised for that product, which is divided into units (“Investment Unit”) with unit value ranging from RMB16.7 to RMB200,000. Individual investors may subscribe for Investment Unit of these on-line products which are generally structured in the way of using the funds from individual investors to purchase solar module or PV related products (“Underlying PV Products”) for leasing to the PV project developers on PV project basis over a specified period. These PV projects may represent the Company’s self developed projects or third party developed projects. Investments made into each on-line product are subject to lock-up period, which ranges from nil to 1,080 days, depending on the terms of each on-line product. During the lock-up period, the individual investors could not transfer or redeem their subscribed Investment Units. After the lock-up period, individual investors are permitted either to transfer their investments in respect of the principal portion to other investors through the on-line platform or, for substantially all products launched, to request the Company to redeem their subscribed Investments Units. Any Investments Units so redeemed by the Company could be put on the on-line platform for re-sale to other investors. Once Investment Units are subscribed and funds are provided, individual investors are guaranteed by the Company with an minimum investment return for their investments, which ranges from an annual rate of 5.25% to 11.9% for the nine-month period ended September 30, 2015, and are also guaranteed for the repayment of funds principal at the end of the investment period by requesting the Company to redeem their investment units. Such redemption rights are granted by the Company for substantially all products launched. Any funds provided by individual investors without subscribing for any on-line products are not entitled to any interest.

7

For each investment into these On-line products by the individual investors with redemption rights granted by the Company, although a tri-party lease agreement is signed among the individual investors, the Company and the PV project developer with individual investors as legal lessor and the PV project developers as legal lessee, the Company is considered as the accounting lessor in substance because 1) the lease terms, rate of return on the investment funds from individual investors, the initial purchase price and the lease rental of the Underlying PV products payable by the PV developers and the purchase contract of the Underlying PV Products entered with manufacturer are negotiated and concluded by the Company without any involvement by the individual investors; and 2) individual investors are entitled to a minimum interest rate as return that are guaranteed by the Company in respect of their funds provided and does not take credit risk in respect of any default payment by the lessee nor risk of claim on the leased assets; 3) the Company is subject to the credit risk as a principal of the lease transaction and has unconditional commitment to return the funds to the individual investors and assume the title of the leased asset after the lock-up period. Based on the above, the individual investors purely provided funds (as lender) to finance the Company (as borrower) for its purchases of the Underlying PV Products for leasing to a solar PV developer in return for a fixed return. In this regard, lease accounting is adopted with the Company as lessor and third party PV developer as lessee for any Underlying PV Products purchased by the Company for leasing to third party project developers. For those on-line products of which the PV project developer (i.e. the legal lessee) is one of SPI’s subsidiaries, the related leasing transactions are eliminated in the condensed consolidated financial statements. Regardless as to whether a SPI’s subsidiaries or a third party PV developer is deemed to be the accounting lessor, all interest bearing funds provided by individual investors are recorded on the condensed consolidated balance sheet as either short term borrowings or long term borrowings included in other noncurrent liability. Funds provided with the lock-up period over one year are classified as long term borrowings and funds with a lock-up period of less than one year are classified as short-term borrowings. Funds that are provided without any on-line products subscribed are non-interest bearing and are reclassified as amount due to individual investors under other current liabilities (See Note 15-Other liabilities).

During the nine-month period ended September 30, 2015, substantially all of the on-line products launched through the on-line platform are related to the Company self-owned PV projects with SPI’s subsidiaries being the lessee. For those on-line products of which the lessee is third party developer, such leases are classified as finance lease in the Company’s condensed consolidated financial statements.

In connection with the launch of the above financing and leasing products, the Company issued to certain third party vendors, Jiangxi LDK Solar Hi-Tech Co., Ltd. (“LDK Jiangxi”) and Suzhou Liuxin Industry Ltd. (“Liuxin”) coupons with total face value of $1,998, nil and nil during the three-month period ended September 30, 2015 and $6,860, $779 and $582 respectively during the nine-month period ended September 30, 2015. Both LDK Jiangxi and Liuxin are related parties of the Company. These coupons are freely transferable between holders but could not be redeemed in cash. Each coupon has an expiry date for redemption. Prior to the expiry date, when the holder subscribe the on-line products through the on-line platform owned by Solar Energy described above, the holders could redeem the coupons and reduce the original purchase price for the on-line products by the face value of the coupons.

For the coupons issued to the third party vendors and LDK Jiangxi, the Company is entitled to the face value in cash or, if mutually agreed between the Company and LDK Jiangxi or between the Company and the relevant third party vendor, to apply the face value as of offset to outstanding accounts payables to these counterparties. Accordingly, the face values of these coupons, totaling $7,639, were recorded as other receivables upon issuance of the coupons. During the nine-month period ended September 30, 2015, other receivable balances related to such coupons totaling $6,854 and $779 were setoff against the related accounts payable balances when mutual agreement with the counterparties had been reached and the legal right to setoff had been established. As of September 30, 2015, other receivable balances due from third party vendors arising from the coupons amounted to $6.

The coupons issued to Liuxin were originally intended for promotional purposes. The face values of these coupons, totaling $582, were therefore recorded as selling expense in the three-month period ended March 31, 2015 because there is no written agreement for the settlement of these coupons. During the three-month period ended September 30, 2015, the Company received full payment of $582 from Liuxin for the face value of the coupons issued and therefore recorded the amounts received as a reduction of selling expenses.

8

The face values of the coupons are recorded in other payables upon issuance, which were reclassified as the Company’s borrowings when the coupons are redeemed through the purchase of on-line products. As of September 30, 2015, all coupons issued to these counterparties had been redeemed.

In order to promote the above on-line products on the platform, the Company offered, from time to time, discount from 5% to 20% on the unit value for Investment Units subscribed by individual investors. The discount offered for on-line products subscribed by individual investors is amortized as interest expense using the effective interest rate method through the end of the lock-up period, which is the earliest date that the Company could be required to repay the unit value in respect of the investment made by individual investors. The Company has also started a series of promotion activities targeting on new member (i.e. new individual investors). During the nine-month period ended September 30, 2015, the Company launched two series of such promotion program pursuant to which any new member registered on-line during the promotion period could be paid back with RMB17.26 in 3 days or RMB9.86 immediately by paying RMB1 into their newly opened account maintained with the Company. By participating in this program, these new members are not obliged to subscribe for any on-line products at that time or in the future in order to get the amount of RMB17.26 in 3 days or RMB9.86 immediately. The difference between the amount paid by new members and the amount to be paid back by the Company under this promotion activity is recorded as selling expenses as incurred, which amounted to $2,238 and $947 during the nine-month and three-month periods ended September 30, 2015. In addition, the Company launched a referral program pursuant to which existing members successfully referred any new member to register a newly opened account on-line and acquire the online products will be entitled to a referral fee of RMB 40 plus 0.55% to 0.8% of the fund principal raised from the newly referred members from time to time in the first two months after the opening of the new account. Such referral fee is recorded as selling expenses as incurred, which amounted to $559 and $389 during the nine-month and three-month periods ended September 30, 2015.

Through its on-line platform, Solar Energy serves as a service agent of the Company to collect funds from and repay funds to individual investors. For the funds collected and repaid through Solar Energy prior to June 17, 2015, the Company made settlement with Solar Energy on a regular basis. From June 17, 2015 onwards, the Company has made repayment of borrowings to individual investors directly while Solar Energy still continues to collect the funds from individual investors and settle with the Company within 2 weeks. For the service provided through the on-line platform, Solar Energy generally charges the Company commission fee at 1% of the fund principal invested into the on-line products by individual investors (see Note 23 — Related Party Transactions) except for those resale of redeemed on-line products by the Company where no commission will be charged to the Company. Such commission fees were recorded as interest expenses on the condensed consolidated statement of operation.

During the nine-month period ended September 30, 2015, the total fund raised from individual investors through Solar Energy amounted to $95,665, of which $8,199 was settled by the coupon issued by the Company to the third party vendors and two related party without cash inflow as described above and $85,495 had been received by the Company from Solar Energy as of September 30, 2015. The Company recorded the remaining funds to be received from Solar Energy in other receivable- due from related party on the condensed consolidated balance sheet as at September 30, 2015, after the reduction of its commission fee of $276 (See Note 23 — Related Party Transactions). During the nine-month period ended September 30, 2015, the funds redeemed to individual investors through Solar Energy amounted to $19,237, of which $18,801 had been repaid by the Company to Solar Energy as of September 30, 2015. The Company recorded the remaining redeemed amounts to be paid to Solar Energy of $436 in other liabilities-due to related party on the condensed consolidated balance sheet as at September 30, 2015. Also, the Company repaid $38,830 directly to individual investors during the nine-months period ended September 30, 2015. In the condensed consolidated statement of cash flows for the nine-month period ended September 30, 2015, the Company recorded the cash received from Solar Energy of $85,219 in relation to funds provided by individual investors in the line item of “Proceeds from loans on solarbao platform through Solar Energy”, and the cash of $57,631 for repayment to individual investors in the line item of “Repayments of loans on solarbao platform directly or through Solar Energy” under financing activities.

Basis of Presentation

The condensed consolidated financial statements are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information. They should be read in conjunction with the financial statements and related notes to the financial statements of Solar Power, Inc. for the years ended December 31, 2014 and 2013 appearing in Solar Power, Inc.’s Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 31, 2015. The Company’s September 30, 2015 and 2014 unaudited interim condensed consolidated financial statements on Form 10-Q have been prepared pursuant to the rules and regulations of the SEC for smaller reporting companies and include the accounts of Solar Power, Inc. and its subsidiaries.

Certain information and note disclosures normally included in the annual financial statements on Form 10-K have been condensed or omitted pursuant to those rules and regulations, although the Company’s management believes the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting of normal recurring adjustments and reclassifications, necessary to present fairly the Company’s consolidated financial position, results of operations and cash flows for all periods presented have been reflected herein. The Company’s financial position, operating results, cash flows and trends in these unaudited condensed consolidated financial statements are not necessarily indicative of future results that may be expected for any other interim period or for the full year.

9

The preparation of unaudited interim condensed consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements as well as the reported amounts of revenues and expenses during the reporting period. Significant accounting estimates used in the preparation of the Company’s consolidated condensed financial statements include: allowance made for doubtful accounts receivable, inventory write-downs, the estimated useful lives of long-lived assets, the impairment of goodwill, long-lived assets and project assets, fair value of derivative asset/liability, valuation allowance of deferred income tax assets, accrued warranty expenses, the grant-date fair value of share-based compensation awards and related forfeiture rates, and fair value of financial instruments. Actual results could differ from those estimates upon subsequent resolution of identified matters.

2. Summary of Significant Accounting Policies

These condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s annual consolidated financial statements and notes thereto contained in the Annual Report on Form 10-K for the year ended December 31, 2014. There have been no significant changes in the Company’s significant accounting policies for the nine–month period ended September 30, 2015, except the adoption of ASC 840 Leasing for the Company’s new business as described in Note 1 Description of Business and Basis of Presentation, as compared to the significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2014.

3. Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), to clarify the principles of recognizing revenue and create common revenue recognition guidance between U.S. GAAP and International Financial Reporting Standards. An entity has the option to apply the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this standard recognized at the date of initial application. ASU 2014-09 is effective for fiscal years and interim periods within those years beginning after December 15, 2017, and early adoption is permitted for periods beginning after December 15, 2016. The Company has not determined which transition method it will adopt, and is currently evaluating the impact of this standard on its consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements — Going Concern (Subtopic 205- 40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which requires management to evaluate, at each annual and interim reporting period, whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued and to provide related disclosures. ASU 2014-15 is effective for the Company for the fiscal year ending December 31, 2016 and for interim periods thereafter. The Company is currently evaluating the impact of this standard on its consolidated financial statements.

In January 2015, the FASB issued ASU No. 2015-01, Income Statement — Extraordinary and Unusual Items (Subtopic 225- 20), which eliminates the concept of reporting for extraordinary items. ASU 2015-01 is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning on January 1, 2016. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

On February 18, 2015, the FASB issued ASU No. 2015-02, Consolidation, which reduces the number of consolidation models and simplifies the current standard. Entities may no longer need to consolidate a legal entity in certain circumstances based solely on its fee arrangements when certain criteria are met. ASU 2015-02 reduces the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity. ASU 2015-02 is effective for the Company’s fiscal year ending December 31, 2016. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, Interest — Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 is effective for the Company on a retrospective basis on January 1, 2016. Early adoption is permitted, but only for debt issuance costs that have not been reported in financial statements previously issued or available for issuance. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. ASU 2015-11 applies to inventory that is measured using the first-in, first-out (“FIFO”) or average cost method and requires measurement of that inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

4. Business combinations

(a) Acquisition of CECEP

On January 15, 2015, SPI and SPI China (HK) Limited, a wholly-owned subsidiary of SPI, entered into a stock purchase agreement (the “Stock Purchase Agreement”) with CECEP Solar Energy Hong Kong Co., Limited (“CECEP HK”). Pursuant to the Stock Purchase Agreement, SPI China (HK) Limited agreed to purchase from CECEP HK 100% of issued and outstanding shares of capital stock of CECEP owned by CECEP HK.

11

Through its respective wholly and non-wholly owned subsidiaries in Italy, CECEP are engaged in the development, acquisition, management, and operation of energy projects and facilities dedicated to the production of alternative energy sources and the facilitation of the distribution, supply and sale of such alternative energy power, through four photovoltaic plants with a total capacity of 4.3 MW in Italy.

The purchase consideration of CECEP consists of cash and SPI’s common stock. In addition to the purchase considerations, the Company is also required to settle the borrowings in the amount of Euro 7,870 ($8,967) due to CECEP HK on behalf of CECEP (“Payable Settlement”). Including the Payable Settlement, the Company needed to settle cash of Euro 3,125 ($3,561) (“Cash Settlement”) and 5,722,977 shares of SPI’s common stock. The Cash Settlement was fully settled in the form of several installments in March and April 2015. The Stock Consideration was settled on January 30, 2015 by the Company, and the common stock was subject to a three-month lockup period as agreed in the Stock Purchase Agreement. The acquisition was consummated on February 16, 2015 upon completion of all closing conditions. All cash consideration has been settled according to the predetermined payment schedule.

The Company issued 5,722,977 shares of its Common Stock to CECEP HK on January 30, 2015. The fair value of the Stock Consideration was determined to be $8,269, which was based on the closing market price of SPI’s common stock on the acquisition date of February 16, 2015, with adjustments for the lockup period and other factors.

The acquisition has been accounted for under ASC 805 Business Combinations. The Company made estimates and judgments in determining the fair value of acquired assets and liabilities, based on management’s experiences with similar assets and liabilities with the assistance from an independent valuation firm. The allocation of the purchase price is as follows:

	USD
Identifiable assets acquired and liabilities assumed
Cash and cash equivalents		1,389
Accounts receivable		394
Other receivable		1,137
Property, plant and equipment		11,041
Deferred tax asset		180
Accounts payable		(244	)
Income tax payable		(130	)
Other accrued liabilities		(1,234	)
Loans payable		(884	)
Identifiable net assets acquired (a)		11,649
Consideration and Payment Settlement (b)		11,830
Non-controlling interests (c)		1,236
Goodwill (b+c- a)		1,417

During the period from the acquisition date to September 30, 2015, CECEP contributed revenue of $1,005 and earnings of $197 to the Company’s consolidated results.

Goodwill primarily represents the expected synergies from combining operations of the Company and CECEP, which are complementary to each other, and any other intangible benefits that would accrue to the Company that do not qualify for separate recognition.

(b) Acquisition of Solar Juice

On March 31, 2015, SPI China (HK) Limited, a wholly-owned subsidiary of SPI, entered into a share purchase agreement (“Purchase Agreement”) with Andrew Burgess, a citizen of Australia as trustee on the terms of the Burgess Absolutely Entitled Trust, Rami Fedda, a citizen of Australia as trustee on the terms of the Fedda Absolutely Entitled Trust, and Allied Energy Holding Pte Ltd, a company incorporated in Singapore and associated with Simon Tan, a citizen of Singapore (collectively, the “Solar Juice Sellers”). Pursuant to the Purchase Agreement, SPI China (HK) Limited agreed to acquire from Solar Juice Sellers 80% of equity interest in Solar Juice Pty Ltd (“Solar Juice”), an Australian proprietary company. The acquisition was consummated on May 28, 2015 upon completion of all closing conditions.

12

Solar Juice is engaged in the distribution of solar photovoltaic panels, solar inverters and other energy efficient solutions, both domestically and internationally.

The purchase consideration consisted of 14,073,354 shares of the Company’s common stock (“Consideration”). The fair value of the Consideration was determined to be $15,578, which was based on the closing market price of the Company’s common stock on the acquisition date of May 28, 2015, with adjustment for the lockup period and other factors.

The acquisition has been accounted for under ASC 805 Business Combinations. The Company made estimates and judgments in determining the fair value of acquired assets and liabilities, based on management’s experiences with similar assets and liabilities with the assistance from an independent valuation firm. The allocation of the purchase price is as follows:

	USD
Identifiable assets acquired and liabilities assumed
Cash and cash equivalents		1,037
Accounts receivable		6,124
Inventories, net		14,728
Prepaid expenses and other current assets		263
Other current assets		525
Intangible assets		4,579
Property, plant and equipment net		301
Deferred tax asset		295
Accounts payable		(10,934	)
Accrued liabilities		(534	)
Prepaid income tax		89
Advance from customers		(230	)
Short term borrowings		(4,305	)
Deferred tax liability		(1,889	)
Identifiable net assets acquired (a)		10,049
Consideration (b)		15,578
Non-controlling interests (c)		2,709
Goodwill (b+c- a)		8,238

During the period from the acquisition date to September 30, 2015, Solar Juice contributed revenue of $20,600 and losses of $673 to the Company’s consolidated results.

Solar Juice is one of the largest distributors of solar panels and inverters in Australia and have well established distribution channel in South East Asia. As a result of the acquisition of Solar Juice, the Company would be able to have immediate access to the solar PV market in Australia, New Zealand and South East Asia, which could enhance the Company’s development of PV projects in those markets. Goodwill primarily represents such expected synergies the Company obtained from the acquisition.

Pursuant to the Purchase Agreement, the Company was granted a call option by the Solar Juice Sellers to acquire remaining 20% equity interest in Solar Juice from them. The exercise price per share of the call option is to be determined based on Solar Juice’s earnings before interest, taxation, depreciation and amortization (“EBITDA”) per share for the year ending December 31, 2015 multiplied by six. The acquisition consideration will be settled with the Company’s common stock if the Company exercises the option. The number of shares to be issued by the Company will be determined by the share price on the exercise date. The call option will be expired on May 28, 2016. The call option meets the definition of a derivative. The Company initially recognized the call option at its fair value of $420 as a derivative asset in Other current assets on the consolidated balance sheet as of September 30, 2015 with gain of $4 and nil arising from the change in fair value recorded in the consolidated statement of operations for the nine-month and three-month periods ended September 30, 2015. The fair value measurement of this call option was further discussed in Note 13 — Fair value measurement.

13

Additionally, Solar Juice received a Notice to Produce Documents request from the Australian Customs Border Protection Service in relation to the tariff classification of certain imports, consistent with similar requests issued to other companies in the solar photovoltaic industry in October 2014. Whilst no official claim for payment has been made on Solar Juice by the Australian Customs Border Protection Service, Solar Juice has submitted an application for an internal review via the Tariff Advice mechanism in January 2015 and is awaiting responses from customs. Based on an internal review by management of the Company as well as external legal advice, Solar Juice considered no significant liability will arise and disclosed the contingency liability (not including any penalties or charges if any) amounting to US$700 as of May 28, 2015. Pursuant to the Purchase Agreement, tax liabilities arising for the period before the closing date of the acquisition will be indemnified by the Solar Juice Sellers. Therefore, the Company considered that no significant liability has been assumed in connection with this acquisition.

14

7. Accounts receivable

Accounts receivable, current and non-current, mainly represents amounts due from customers for 1) sales of Solar PV projects; 2) rendering of EPC services; 3) supply of electricity under power supply agreements (“PPA”); and 4) sales of solar PV related components.

The balance of allowance for doubtful accounts was $5,586 and $766 as of September 30, 2015 and December 31, 2014, respectively. There was write-off for bad debts of $23 and recovery of previously written off of nil for the nine-month and three-month periods ended September 30, 2015, respectively.

The allowance for doubtful accounts is provided against gross accounts receivable balances based on the Company’s best estimate of the amount of probable credit losses in the Company’s accounts receivable. The Company grants credit terms to credit-worthy customers. Terms vary per contract terms and range from 30 to 365 days. Contractually, the Company may charge interest for extended payment terms and require collateral. The Company regularly monitors and assesses the risk of not collecting amounts owed by customers. This evaluation is based upon a variety of factors, including an analysis of amounts current and past due along with relevant history and facts particular to the customer. The Company does not have any off-balance-sheet credit exposure related to its customers.

Included in the receivable balances arising from EPC services as at September 30, 2015 and December 31, 2014 was an amount of $13,214 and $6,794 respectively due from a customer in the PRC, Xinyu Realforce Energy Co., Ltd (“Realforce”). In the second half of 2014, the Group entered into an EPC contract with Realforce to construct a 21MW rooftop PV station. The construction of the PV station had been completed prior to December 31, 2014. In April 2015, Realforce entered into a sales and leaseback arrangement with the Company for the purpose of settling part of the outstanding receivable arising from the EPC contract. At that time, the outstanding receivable balances due from Realforce amounted to $24,840. Pursuant to the sales and leaseback arrangement, Realforce sold the Company certain solar PV components installed in the 21MW rooftop PV station at their fair value of $11,292 and immediately leased them back over a 10-year period with annual interest rate of 10% per annum under a finance lease contract. As a result of the above arrangement, the Company reduced the receivable balance due from Realforce by the fair value of the solar PV components of $11,292 and recognized a finance lease receivable of $11,292 due from Realforce. No gain or loss was recognized in the condensed consolidated statement of operation in relation to the above settlement through sales and leaseback arrangement. For the remaining $13,545 accounts receivable balances due from Realforce, the Company and Realforce have not reached any settlement arrangement up to the date of issuance of the financial statements. As at September 30, 2015, 100% equity interests in Realforce were pledged to the Company to secure its repayment obligations under the finance lease contract and the outstanding accounts receivable balances.

8. Project Assets

* All of the projects costs under this category were recorded as project assets, noncurrent.

Project assets under development-Company as project owner are primarily related to the following projects:

16

Calwaii Projects

In 2014, the Company acquired solar PV assets, primarily including land use right and pre-contract costs relating to forty-three solar PV systems owned by Calwaii. During the nine-month period ended September 30, 2015, sales of four solar PV systems were consummated (see below). As of September 30, 2015 and December 31, 2014, incurred costs for PV solar systems under the Calwaii’s projects in Hawaii amounted to $23,570 and $23,943 respectively.

Solar Mountain Creek Parent LLC

The carrying amount of this project amounted to $17,239 and 17,864, net of impairment of $2,787 and $2,055 as of September 30, 2015 and December 31, 2014 respectively.

Pursuant to a letter of intent dated November 10, 2014 and a sales agreement dated December 31, 2014, the Company agreed to sell the PV solar systems of this project upon its completion of construction at a consideration of $17,864. In July 2015, the Company entered into a supplemental agreement to extend the deadline of final completion to the end of 2015 and compensate the buyer up to $625. The compensation would be deducted from the consideration. Management assessed the recoverable amounts of this project asset and as a result the carrying amount of this project asset was written down to the recoverable amount of $17,239. The estimate of recoverable amount of this project asset was based on this asset’s fair value less costs of disposal, and the fair value was determined by reference to the quoted price from third party. The Company accounted for this sales transaction using the deposit method under ASC 360-20, Real Estate Accounting, and did not recognize any revenue and profit for this sales transaction for the year ended December 31, 2014 and the nine-month period ended September 30, 2015 as certain closing conditions as specified in the sales agreement had not been met and accordingly sales had not been consummated as of September 30, 2015.

RE Capital Projects

In April 2015, the Company entered into an interest purchase agreement with RE Capital Pte. Ltd. to acquire its 100% membership interest in seventeen PV project companies in Japan (“RE Capital companies”) at a consideration of $8,800 consisting of $3,300 cash and $5,500 worth of the Company’s common stock (See Note 18 — Stockholders’ Equity). RE Capital companies’ total assets and liabilities only included land and pre-contract cost related to solar projects of 52MWs in total. Additionally, RE Capital companies had not entered into any power generation contracts with any utilities companies. As a result, Management concluded that the acquisition of 100% managing member interest in RE Capital companies did not meet the definition of a business combination as the primary inputs (the solar plant, which had yet to be constructed) were not available on the acquisition date. As of September 30, 2015, the payment made and cost incurred of $8,123 in total up to September 30, 2015 were included and recorded as project assets.

Solar Park Development 4 Ltd

In June 2015, the Company entered into another shares sales agreement with Blackrock Income UK Holding Limited to transfer the 100% outstanding share of Solar Park Development 4 Ltd at a consideration of $10,716 (equivalent to GBP7,000), which owned a grid-connected solar project of 6.2 MW developed by the Company.

Project assets under development-Company expected to be project owner upon completion of construction are related to the following projects:

In late 2014, the Company entered into two EPC contracts with third-party projects owners under an arrangement pursuant to which there was mutual understanding between the Company and the respective project owners that the title and ownership of the PV solar power systems would transfer to the Company upon the completion of construction and grid connection of the PV systems under the EPC contracts by the Company. The PV solar systems were pledged to the Company, as part of the EPC contract terms, to secure the expected title transfer upon grid connection. In 2015, the Company entered into similar arrangement with two third-party project owners.

Unlike other EPC contracts which are accounted for in accordance with ASC 605, no revenue is recognized for these four EPC contracts as no revenue is expected to be realized or earned from the EPC contracts, which were signed to facilitate the construction of the related solar PV systems by the Company and secure the Company’s financial interests in these projects through the pledge of the related solar PV systems. Given the substance of the transactions, the mutual understanding reached between the Company and the third-party project owners and the remote possibility of not obtaining the legal title upon grid connection, the Company accounts for these projects as owned and record the costs incurred under Project Assets on the condensed consolidated balance sheet. Based on the Company’s intention to sell or hold for own use, the projects costs incurred for these EPC contracts are presented as operating activities or investing activities respectively in the condensed consolidated statement of cash flows.

11. Investment in EnSync, Inc.

On April 17, 2015, the Company and EnSync, Inc. (formerly known as ZBB Energy Corporation) (“ENS”), a Wisconsin corporation, entered into a Securities Purchase Agreement pursuant to which ENS will issue and sell to the Company for an aggregate purchase price of $33,390 which is to be settled in cash, a total of (i) 8,000,000 shares (the “Purchased Common Stock”) of ENS’s common stock based on a purchase price per common share of $0.6678 and (ii) 28,048 shares of the ENS’s convertible preferred stock (the “Convertible Preferred Stock”) which are convertible into an aggregate of 42,000,000 shares of common stock, representing a purchase price of $0.6678 per common stock on an as-if converted basis, over a four-year period with 25% of issued Convertible Preferred Stock became convertible in each of the next four years if the Company meets certain conditions relating to the Company’s purchases of minimum megawatt of solar related products from ENS in each of the next four years as set out in the Securities Purchase Agreement. The purchase prices of the products are not fixed or determinable in the agreements, but ENS shall not at any time sell a lower quantity of the products under similar terms and conditions to other buyers at prices below those provided to the Company. The conversion is subject to adjustment for stock splits, stock dividends, and other designated capital events. ENS also entitles the Company to acquire 50,000,000 shares of ENS’s common stock (the “Warrant”) for an aggregate amount of $36,729, or $0.7346 per share, subject to adjustment for stock splits, stock dividends, and other designated capital transactions. The consummation of the Securities Purchase Agreement is subject to certain closing conditions.

ENS develops, licenses, and manufactures innovative energy management systems solutions serving the commercial and industrial building, utility and off-grid markets.

On July 13, 2015, all closing conditions relating to the Securities Purchases Agreement was met. The Purchased Common Stock, Convertible Preferred Stock and Warrant have been issued to the Company.

The Purchased Common Stock represents approximately 17% of the outstanding common stock of ENS as at July 13, 2015. Additionally, assuming the full conversion of the Convertible Preferred Stock (and that no other shares of common stock of ENS are issued), the Company would own greater than a majority of the outstanding common stock of ENS.

The Company also entered into a supply agreement with ENS pursuant to which ENS will sell and the Company will purchase certain products offered by ENS from time to time, including energy storage systems for solar projects (the “Supply Agreement”). Convertibility of the Convertible Preferred Stock is dependent upon the Company making purchases of and payments for energy storage systems under the Supply Agreement as follows: the first one-fourth (the “Series C-1 Preferred Stock”) of the Purchased Preferred Shares only become convertible upon the receipt of final payment for 5 megawatts (“MW”) that are purchased by SPI in accordance with the Supply Agreement; the second one-fourth (the “Series C-2 Preferred Stock”) only become convertible upon the receipt of final payment for an aggregate of 15 MW worth of the Supply Agreement; the third one-fourth (the “Series C-3 Preferred Stock”) only become convertible upon the receipt of final payment for an aggregate of 25 MW worth of the Supply Agreement; and the last one fourth (the “Series C-4 Preferred Stock”) only become convertible upon the receipt of final payment for an aggregate of 40 MW worth of the Supply Agreement. The Convertible Preferred Stock will not become convertible unless the payment for the Supply Agreement is received. If the Company complies with the provisions of the Supply Agreement, it will make sufficient purchases for each tranche of the Convertible Preferred Stock to vest and become convertible over the next four years. However, the Convertible Preferred Shares will become convertible at any time when the relevant payments are received by ENS for the specified purchases, even if the payments are made later or earlier than the schedule set out in the Supply Agreement.

The Convertible Preferred Stock possesses no voting rights except as required by law or for certain matters specified in the agreement. The Convertible Preferred Stock are perpetual, are not eligible for dividends, and are not redeemable. Besides, so long as any shares of Convertible Preferred Stock are outstanding, ENS may not pay dividends on its common stock and may not redeem more than $100 in common stock per year. The Convertible Preferred Stock has a liquidation preference equal to the greater of $28,048 and the distribution of the entire assets on an as-converted basis.

The Warrant vests and becomes exercisable once the Company purchases and pays for 40 MW of the Supply Agreement, and will not vest or become exercisable if those purchases and payments do not occur before the termination of the Warrant, which will occur, whether the Warrant has vested or not, on July 13, 2019. Prior to exercise, the Warrant provides the Company with no voting rights. The Warrant may not be partially exercised. As the closing price of ENS’s common stock at September 30, 2015 was below the exercise price of the Warrant, the Warrant was out-of-the-money at that date.

20

In connection with the Securities Purchase Agreement, the Company entered into a governance agreement with ENS (the “Governance Agreement”). Under the Governance Agreement, the Company is entitled to nominate one director to the board of directors of ENS for so long as the Company holds at least 10,000 convertible preferred shares or 25 million shares of common stock or common stock equivalents (the “Requisite Shares”). Additionally, for so long as the Company holds the Requisite Shares (1) following the time at which the Series C-2 Preferred Stock shall have become convertible in full, SPI shall be entitled to nominate a total of two directors and (2) following the time at which the Series C-3 Preferred Stock shall have become convertible in full, SPI shall be entitled to nominate a total of three directors. Provided in no event shall the Company be entitled to nominate a number of directors to the Board that would represent a percentage of the Board greater than the percentage determined by dividing the number of Common Stock Equivalents held by the Company by the sum of (A) the total shares of ENS’s Common Stock outstanding and (B) the number of shares of Common Stock into which the Preferred Stock held by the Company is convertible.

The Company accounts for this investment in the Purchased Common Stock under the equity method. The Company includes its proportionate share of net earnings or loss attributable to common stockholders and other comprehensive income in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The Company accounts for the investment in the Convertible Preferred Stock as other investment carried at cost in the Condensed Consolidated Balance Sheets. The Company accounts for the Warrant as a derivative asset at fair value which is included in Derivative asset, noncurrent in the Condensed Consolidated Balance Sheet as of September 30, 2015. The derivative asset was initially recorded at its fair value of $16,947. The change in fair value of $10,793 was recorded under Other income-Change in market value of derivative asset/liability in the Condensed Consolidated Statement of Operations for the nine-month and three-month periods ended September 30, 2015. The total consideration of $33,390 less the fair value of warrants as of July 13, 2015 was allocated, based on relative fair value, between the investments in the Purchased Common Stock and investment in the Convertible Preferred Stock, which were initially recorded at $3,244 and $13,199, respectively.

In 2009, Solar Power, Inc. capitalized a PV solar system relating to the Aerojet 1 solar development project along with the associated financing obligation, recorded under financing and capital lease obligations, net of current portion, in the Condensed Consolidated Balance Sheets. Due to certain guarantee arrangements as disclosed in Note 22 — Commitments and Contingencies, the Company will continue to record this PV solar system in property, plant and equipment with its associated financing obligation in Financing and capital lease obligations as long as it maintains its continuing involvement with this project. The income and expenses relating to the underlying operation of the Aerojet 1 solar development project are recorded in the Condensed Consolidated Statement of Operations.

13. Fair value measurement

In arriving at fair-value estimates of the call option as discussed in Note 4- Business Combination, the Company utilizes the most observable inputs available for the valuation technique employed. If a fair-value measurement reflects inputs at multiple levels within the fair value hierarchy, the fair-value measurement is characterized based upon the lowest level input. For the Company, recurring fair-value measurements are performed for the derivative assets. The Company does not have any derivative asset that reduce risk associated with hedging exposure and has not designated the derivative asset as a hedge instrument.

The Company did not have any derivatives valued using Level 1 and Level 2 inputs as of September 30, 2015 and December 31, 2014. The derivative asset relating to the call option was classified in Level 3 of the fair value hierarchy in which management has used at least one significant unobservable input in the valuation model. The fair value of the derivative asset was $420 and $424 at the grant date of May 28, 2015 and September 30, 2015 respectively, which were recorded as other financial assets in the Consolidated Balance Sheet as of September 30, 2015. Gain arising from change in fair value of $4 and nil was recorded as Other income-others in the consolidated statement of operations for the nine-month and three-month periods ended September 30, 2015 respectively. The Company determines the fair value using binomial model with significant input on the fair value of the remaining 20% equity interest of Solar Juice and volatility unobservable in the market. The volatility is determined by the average standard derivation of the comparable companies applicable over a time period corresponding to the remaining life of the call option. Significant increases or decreases in this unobservable input would result in a significantly lower or higher fair value measurement.

The derivative asset relating to the Warrant to acquire ENS’s common stock was classified in Level 3 of the fair value hierarchy in which management has used at least one significant unobservable input in the valuation model. The fair value of the derivative asset was $6,154 on September 30, 2015, which were recorded as Derivative asset in the Consolidated Balance Sheet as of September 30, 2015. Gain arising from change in fair value of $10,793 was recorded as Other income-Change in market value of derivative asset/liability in the consolidated statement of operations for the nine-month and three-month periods ended September 30, 2015 respectively. The Company determines the fair value of the Warrant using binomial model with significant inputs on the vesting

22

schedule and volatility unobservable in the market. The vesting schedule of the Warrant is estimated by the Management based on expected timetable to fulfill the vesting condition. The volatility is determined by the average standard derivation of the comparable companies applicable over a period with length commensurate to the time to maturity of the Warrant as of the Valuation Date. Significant variance of the above-mentioned inputs would result in a significantly lower or higher fair value measurement.

The Convertible Preferred Stock of ENS was classified in Level 3 of the fair value hierarchy in which management has used at least one significant unobservable input in the valuation model. The fair value of the Convertible Preferred Stock of ENS is determined by the fair value of the total common stock with a discount for Lack of Marketability Discount (“LOMD”). The LOMD as of the Valuation Date is derived by reference to put option based on Black-Scholes Option Pricing Model, with significant inputs on the volatility and expected terms of each tranche of the Preferred Stock unobservable in the market. The volatility is determined by the average standard derivation of the comparable companies applicable over a period with length commensurate to the expected term of the Convertible Preferred Stock, and the expected term of each tranche of the Convertibel Preferred Stock is based on Management’s estimation of the conversion schedule. Significant variance of the above-mentioned inputs would result in a significantly lower or higher fair value measurement.

There have been no transfers between Level 1, Level 2, or Level 3 categories.

There were no assets or liabilities measured on a non-recurring basis as of September 30, 2015 and December 31, 2014. For financial instruments that are not required to be measured at fair value, the following method and assumptions were used to estimate the fair value as at September 30, 2015 and December 31, 2014:

Cash and cash equivalents, restricted cash, accounts receivable and payable, short term investments, bank deposits with maturity over three months, finance lease receivables, current, accrued liabilities, advance from customers and other current liabilities — costs approximates fair value because of the short maturity period.

Notes receivable, current, and notes receivable, noncurrent — The fair value of Notes receivable, current were based on anticipated cash flows, which approximates carrying value, and were classified in Level 2 of the fair value hierarchy. The fair value of Notes receivable, noncurrent were classified in Level 3 of the fair value hierarchy. The Company used multiple techniques, including an income approach applying discounted cash flows approach, to measure the fair value using Level 3 inputs; the results of each technique have been reasonably weighted based upon management’s judgment applying qualitative considerations to determine the fair value at the measurement date. The fair value of notes receivable is determined to approximate its carrying value.

Convertible bonds. The estimated fair value was $52,968 and $39,423 as of September 30, 2015 and December 31, 2014. The fair value of convertible bonds was classified in Level 2 of the fair value hierarchy. The Company determines the fair value using binomial model with significant input on prices and votes observable in the market.

Short term borrowings. The carrying amount approximates fair value due to the short maturity and their variable market rates of interest that change with current Prime and no change in counterparty credit risk and were classified as Level 2 of the fair value hierarchy.

Finance lease receivables, noncurrent, and other noncurrent liabilities. The Company used discounted cash flow approach to determine the fair value, which was classified in Level 3 of the fair value hierarchy. The fair value of finance lease receivables, noncurrent, and other noncurrent liabilities is determined to approximate its carrying value.

On June 15, 2015, the Company entered into a convertible promissory note purchase agreement with Vision Edge Limited (“Vision Edge”), whereby the Company agreed to sell and issue to Vision Edge convertible promissory note in an aggregate principal amount of $20,000 which could be converted into 7,407,410 Common Shares at a fixed conversion price of $2.70 unless adjusted for anti-dilution. The convertible notes bore no interest, and might be wholly converted into shares of the Company’s common stock at any time prior to maturity at the option of the investor. The commitment date of the convertible promissory note is on June 29, 2015. The convertible promissory note was due and payable on June 29, 2016. Also, as mentioned in Note 17 — Stock option, on June 15, 2015, the Company entered into option agreement with Vision Edge, whereby the Company agreed to grant Vision Edge an option to purchase from the Company a total of 7,407,410 Shares for an aggregate purchase price of $20,000, or $2.70 per share, prior to December 15, 2015. The above instruments issued to Vision Edge on June 15, 2015, including convertible promissory note and stock option, were accounted for as a bundled transaction. The proceeds from the issuance of convertible promissory note were allocated to the two elements based on the relative fair values of the convertible promissory note and the stock options at the time of issuance. There is no beneficial conversion feature in this convertible promissory note because the initial conversion price of US$ 2.66 per share after the proceeds are allocated to the option is greater than the fair value of the Company’s common stock on the commitment date of June 29, 2015. The convertible promissory note and stock options were initially recorded at $19,705 and $295, respectively, according to the allocation of the total proceeds. The discount of $295 of the convertible promissory note is amortized as interest expense using the effective interest rate method through the earliest demand payment date, i.e. June 29, 2016. The stock option was accounted for as an equity instrument and was recorded within equity.

17. Stock option

On February 15, 2012, the Company’s Board of Directors approved the issuance of a warrant agreement for Cathay General Bancorp to purchase 300,000 shares of the Company’s common stock at $0.75 per share related to the credit facility entered into with Cathay Bank for an original aggregate principal amount of $9,000. The fair value of $0.29 per share was determined using the Black-Scholes-Merton model. Assumptions used in calculating fair value were as follows: a risk free interest rate of 0.38%, expected volatility of 103%, zero expected dividend yield, and an expected term of 3 years. The warrant is exercisable anytime for an exercise price of $0.75 per share before its expiration. This warrant expired on February 15, 2015.

19. Stock-based Compensation

The Company measures stock-based compensation expense for all stock-based compensation awards based on the grant-date fair value and recognizes the cost in the financial statements over the employee requisite service period.

The following table summarizes the stock-based compensation expense, by type of awards for the periods as follow (in thousands):

	For the Three Months Ended					For the Nine Months Ended
	September 30, 2015		September 30, 2014			September 30, 2015		September 30, 2014

Stock-based compensation expense recognized in the Condensed Consolidated Statements of Operations is based on awards ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Determining Fair Value

Valuation and Amortization Method — The Company estimates the fair value of service-based and performance-based stock options granted using the Black-Scholes option-pricing formula. The fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. In the case of performance-based stock options, amortization does not begin until it is determined that meeting the performance criteria is probable. Service-based and performance-based options typically have a five to ten year life from date of grant and vesting periods of three to four years.

Expected Term — The Company’s expected term represents the period that the Company’s stock-based awards are expected to be outstanding. For awards granted subject only to service vesting requirements, the Company utilizes the simplified method for estimating the expected term of the stock-based award, instead of historical exercise data. For its performance-based awards, the Company has determined the expected term life to be five years based on contractual life and the seniority of the recipient.

Expected Volatility — The Company uses historical volatility of the price of its common shares to calculate the volatility for its granted options.

Expected Dividend — The Company has never paid dividends on its common shares and currently does not intend to do so, and accordingly, the dividend yield percentage is zero for all periods.

27

Risk-Free Interest Rate — The Company bases the risk-free interest rate used in the Black-Scholes valuation model upon the implied yield curve currently available on U.S. Treasury zero-coupon issues with a remaining term equal to the expected term used as the assumption in the model.

Assumptions used in the determination of the fair value of share-based payment awards using the Black-Scholes model for stock option grants during the three-month and nine-month periods ended September 30, 2015 and 2014 were as follows:

	For the Three Months Ended		For the Nine Months Ended
	September 30, 2015	September 30, 2014	September 30, 2015	September 30, 2014
Expected term	4	4	4	4
Risk-free interest rate	1.49% - 1.72%	1.25%	1.32% - 2.24%	1.25%
Expected volatility	139% - 141%	1.26%	139% - 142%	95%
Expected dividend yield	0%	0%	0%	0%

Equity Incentive Plan

On November 15, 2006, subject to approval of the stockholders, the Company adopted the 2006 Equity Incentive Plan (the “Plan”) which permits the Company to grant stock options to directors, officers or employees of the Company or others to purchase shares of common stock of the Company through awards of incentive and nonqualified stock options (“Option”), stock (“Restricted Stock” or “Unrestricted Stock”) and stock appreciation rights (“SARs”). The Plan was approved by the stockholders on February 7, 2007.

The Company has granted time-based share options and restricted stock under the Plan to directors, officers, employees and individual consultants of the Company. The time-based options generally vest 25% annually and expire five to ten years from the date of grant. Total number of shares reserved and available for grant and issuance pursuant to this Plan is equal to 9% of the number of outstanding shares of the Company. Shares issued under the Plan will be drawn from authorized and unissued shares or shares now held or subsequently acquired by the Company. Outstanding shares of the Company shall, for purposes of such calculation, include the number of shares of stock into which other securities or instruments issued by the Company are currently convertible (e.g., convertible preferred stock, convertible debentures, or warrants for Common Stock), but not outstanding options to acquire stock. At September 30, 2015 there was no share available for grant under the plan (9% of the outstanding shares of 676,867,538 less options and restricted stock outstanding and exercised since inception).

The exercise price of any Option will be determined by the Company when the Option is granted and may not be less than 100% of the fair market value of the shares on the date of grant, and the exercise price of any incentive stock option granted to a stockholder with a 10% or greater shareholding will not be less than 110% of the fair market value of the shares on the date of grant. The exercise price per share of a SAR will be determined by the Company at the time of grant, but will in no event be less than the fair market value of a share of Company’s stock on the date of grant.

On January 12, 2015, February 13, 2015, and June 29, 2015, the Board of Directors approved the grants of restricted stock unit awards (“RSU”) to core management members, other management and staff, pursuant to the terms of the 2006 Equity Incentive Plan. The total number of RSUs granted is 20,468,400 shares. Among these, the vesting schedules for the chairman, deputy chairman and CFO (“core management”) are 100% vested at the grant date and the vesting schedules for the rest RSUs granted to other management and staff would be vested within the next four years equally. The Company used the market price of its share at grant date as the fair value of the RSUs in calculating the stock based compensation expense. The core management exercised all RSUs of 19,200,000 and all these shares were issued to them in March 2015 (See Note 18 — Stockholders’ Equity).

20. Income Taxes

The Company calculates its interim income tax provision in accordance with ASC 740-270 Income Taxes. At the end of each interim period, the Company estimates the annual effective tax rate and applies that rate to its ordinary quarterly earnings. The tax expense or benefit related to significant, unusual, or extraordinary items that will be separately reported or reported net of their related tax effect, is recognized in the interim period in which those items occur. The Company evaluates its ability to recover deferred tax assets, in full or in part, by considering all available positive and negative evidence, including past operating results and our forecast of future taxable income on a jurisdictional basis. The Company bases its estimate of current and deferred taxes on the tax laws and rates that are currently in effect in the appropriate jurisdiction. Changes in laws or rates may affect the tax provision as well as the amount of deferred tax assets or liabilities.

The effective income tax rate of the Company for the nine-month period ended September 30, 2015 and 2014 was (0.6)% and (9.9)%, respectively, and the three-month period ended September 30, 2015 and 2014 was 2.5% and (12.9)%, respectively. For both 2015 and 2014, the Company expects to generate taxable income in certain jurisdictions while still experiencing an overall worldwide loss.

The Company has not provided for deferred taxes relating to the undistributed earnings of its foreign subsidiaries (primarily the subsidiaries in the People’s Republic of China) amounted to $2.4 million and $8.8 million as of September 30, 2015 and December 31, 2014, respectively, which are expected to be permanently reinvested.

The Company and its subsidiaries did not have any unrecognized tax benefits or liabilities as of September 30, 2015 and December 31, 2014. The Company does not anticipate that its unrecognized tax benefits or liability position will change significantly over the next twelve months.

21. Net Loss Per Share of Common Stock

Basic loss per share is computed by dividing income attributable to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted loss per share reflects the potential dilution of shares by adding other Common Stock equivalents, including Common Stock options, warrants, and restricted Common Stock, in the weighted average number of common shares outstanding for a period, if dilutive. Potentially dilutive shares are excluded from the computation if their effect is anti-dilutive. As a result of the net loss for the nine-month and three-month periods ended September 30, 2015 and 2014, there is no dilutive impact to the net loss per share calculation for the period.

The following table presents the calculation of basic and diluted net loss per share:

	For the Three Months Ended						For the Nine Months Ended
	September 30, 2015			September 30, 2014			September 30, 2015			September 30, 2014
Numerator:
Net loss attributable to stockholders	$	(30,827	)	$	(8,283	)	$	(82,431	)	$	(10,453	)

22. Commitments and Contingencies

Commitments

Guarantee — on December 22, 2009, in connection with an equity funding of STP related to the Aerojet 1 solar development project, the Company along with STP’s other investors entered into a Guaranty (“Guaranty”) to provide the equity investor, Greystone Renewable Energy Equity Fund (“Greystone”), with certain guarantees, in part, to secure investment funds necessary to facilitate STP’s payment to the Company under the EPC. Specific guarantees made by Solar Power, Inc. include the following in the event of the other investors’ failure to perform under the operating agreement:

• Operating Deficit Loans — the Company would be required to loan Master Tenant or STP monies necessary to fund operations to the extent costs could not be covered by Master Tenant’s or STP’s cash inflows. The loan would be subordinated to other liabilities of the entity and earn no interest; and

• Exercise of Put Options — At the option of Greystone, the Company may be required to fund the purchase by Managing Member of Greystone’s interest in Master Tenant under an option exercisable for 9 months following a 63-month period commencing with operations of the Facility. The purchase price would be equal to the greater of the fair value of Greystone’s equity interest in Master Tenant or $1,000. This option has been exercised on December 30, 2014 and this guarantee has been released accordingly.

The Company has recorded on its Condensed Consolidated Balance Sheet the guarantees of $60 and $71 at September 30, 2015 and December 31, 2014. These amounts, less related amortization, are included in accrued liabilities. These guarantees for the Aerojet 1 project are accounted for separately from the financing obligation related to the Aerojet 1 project because they are with different counterparties.

Financing Obligation — the guarantees associated with Aerojet 1 constitute a continuing involvement in the project. While the Company maintains its continuing involvement, it will apply the financing method and, therefore, has recorded and classified the proceeds received of $9,959 and $10,911 from the project in financing and capital lease obligations as of September 30, 2015 and December 31, 2014, respectively. At September 30, 2015 and December 31 2014, $8,948 and $10,092, respectively, were recorded as noncurrent Financing and capital lease obligations, with $1,011 and $819 recorded as other current liabilities.

Performance Guaranty — on December 18, 2009, the Company entered into a 10-year energy output guaranty related to the photovoltaic system installed for STP at the Aerojet 1 facility in Rancho Cordova, CA. The guaranty provided for compensation to STP’s system lessee for shortfalls in production related to the design and operation of the system, but excluding shortfalls outside the Company’s control such as government regulation. The Company believes that the probability of shortfalls is unlikely and if they should occur they would be covered under the provisions of its current panel and equipment warranty provisions. At September 30, 2015 and December 31 2014, there continues to be no charges against the Company’s reserves related to this performance guaranty.

Product Warranties — The Company offer the industry standard warranty up to 25 years for its PV panels and industry standard five to ten years on inverter and balance of system components. Due to the warranty period, the Company bear the risk of extensive warranty claims long after the Company has shipped product and recognized revenue. In the Company’s cable, wire and mechanical assemblies business, the Company’s historically warranty claims have not been material. In the Company’s solar PV business, the greatest warranty exposure is in the form of product replacement.

During the quarter ended September 30, 2007 and continuing through the fourth quarter of 2010, the Company installed own manufactured solar panels. Other than this period, the Company only installed panels manufactured by unrelated third parties as well as the Company’s principal shareholder and formerly controlling shareholder, LDK. Certain PV construction contracts entered into during the recent years included provisions under which the Company agreed to provide warranties to the buyer. As a result, the Company recorded the provision for the estimated warranty exposure on these contracts within cost of sales. Since the Company do not have sufficient historical data to estimate its exposure, the Company have looked to its own historical data in combination with historical data reported by other solar system installers and manufacturers. Due to the absence of historical material warranty claims, the Company have not recorded a material warranty accrual related to solar energy systems as of September 30, 2015 and December 31, 2014.

Operating leases — The Company leases facilities under various operating leases, some of which contain escalation clauses, which expire through 2020. The Company also leases vehicles under operating leases. Rental expenses under operating leases included in the statement of operations were $550 and $120 for the three-month period ended September 30, 2015 and 2014 respectively and $1,905 and $236 for the nine-month period ended September 30, 2015 and 2014 respectively.

31

Future minimum payments under all of our non-cancelable operating leases are as follows as of September 30, 2015:

2015 (remaining three months)	$	973
2016		3,215
2017		1,857
2018		1,454
2019		902
2020		737
Thereafter		8,743
	$	17,881

Capital commitments — As of September 30, 2015 and December 31, 2014, the Company had capital commitments of approximately $85,813 and $59,354 respectively. The capital commitments were solely related to contracts signed with vendors for procurement of services or PV related products used for the construction of solar PV systems being developed by the Company.

The capital commitments as at balance sheet dates disclosed above do not include those incomplete acquisitions for investment and business as at balance sheet dates as the agreements could either be terminated unconditionally without any penalty or cancelable when the closing conditions as specified in the agreements could not be met. The occurrence of non-fulfillment of those closing conditions are not considered as remote.

Contingencies

From time to time, the Company is involved in various other legal and regulatory proceedings arising in the normal course of business. While the Company cannot predict the occurrence or outcome of these proceedings with certainty, it does not believe that an adverse result in any pending legal or regulatory proceeding, individually or in the aggregate, would be material to our consolidated financial condition or cash flows; however, an unfavorable outcome could have a material adverse effect on our results of operations for a specific interim period or year.

In connection with the acquisition, the Company paid $2,000 as deposits for the acquisition, such prepaid deposits were subsequently agreed by both parties to offset against certain payable balances due to LDK HK on September 30, 2015. The transaction is subject to several closing conditions including completion of satisfactory due diligence. This acquisition has not been consummated as of the date of issuance of these financial statements.

As of September 30, 2015 and December 31, 2014, the Company had accounts payable to LDK of $5,480 and $34,150, respectively. The accounts payable balances as at September 30, 2015 were primarily related to purchases of solar cells for solar development projects. The solar cells purchased from LDK during the nine-month and three-month periods ended September 30, 2015 amounted to $8,378 (2014: nil) and $6,235 (2014: nil) respectively. The Company also consigned LDK to process solar cells to solar panels for its on-line platform business in 2015.

The accounts payable balances as at December 31, 2014 were primarily related to an amount that are subject to settlement arrangement with LDK. On December 30, 2014, the Company entered into a Settlement and Mutual Release (“Settlement Agreement”) with LDK Solar International Company Limited (“LDK HK”), a wholly owned subsidiary of LDK, pursuant to which LDK HK agreed to release and discharge the Company from all actions, claims, demands, damages, obligations, liabilities, controversies and executions arising out of the Company’s net payables of $28,775 to LDK HK and its subsidiaries (“LDK HK Group”), in exchange for an aggregate settlement amount of $11,000. Under the Settlement Agreement, the Company agreed to pay the settlement amount of $11,000 by instalments in accordance with a predetermined schedule and LDK HK has the right to cancel the agreed settlement if any instalment payment is delayed for more than 30 days. The agreed payment schedule for the settlement amount of $11,000 is $380 on or before December 31, 2014, $2,000 on or before January 31, 2015, $1,620 on or before March 30, 2015, $2,000 on or before June 30, 2015, $1,000 on or before July 31, 2015, $2,000 on or before September 30, 2015 and $2,000 on or before December 31, 2015 (“Last Payment Obligation”). As the settlement amount will only be fully paid by December 31, 2015 in accordance with the Settlement Agreement, the Company did not derecognize the waived liability of $17,775, being the difference between the amounts of $28,775 that were subject to the settlement and the agreed settlement amount of $11,000, from its consolidated balance sheet as of December 31, 2014. As of September 30, 2015, the Company had made installment payments on schedule and had paid $9,000 in total to LDK HK in accordance with the Settlement Agreement. On September 30, 2015, the Company entered into a supplemental agreement with LDK HK pursuant to which LDK HK agrees the Company to apply the prepayment of $2,000 made to LDK HK under the LDK Share Purchase Agreement to satisfy the Company’s Last Payment Obligation under Settlement Agreement. This agreement does not affect the validity of the Share Purchase Agreement and LDK HK and the Company agrees to postpone the dates of performance under the Share Purchase Agreement. The Company derecognized the waived liabilities of $17,775 from its condensed consolidated balance sheet as of September 30, 2015 in accordance with the Settlement Agreement and the supplemental agreement since the Company had fully paid the settlement amount of $11,000. As LDK is the Company’s principal shareholder, this waived liabilities of $17,775 was accounted for as a capital transaction by increasing additional paid in capital as of September 30, 2015.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Quarterly Report on Form 10-Q and other written reports and oral statements made from time to time by the Company may contain so-called “forward-looking statements,” all of which are subject to risks and uncertainties. One can identify these forward-looking statements by their use of words such as “expect,” “plan,” “will,” “may,” “anticipate,” “believe,” “estimate,” “should,” “intend,” “forecast,” “project” the negative or plural of these words, and other comparable terminology. One can identify them by the fact that they do not relate strictly to historical or current facts. These statements are likely to address the Company’s growth strategy, financial results and product and development programs. One must carefully consider any such statement and should understand that many factors could cause actual results to differ from the Company’s forward-looking statements. These factors include inaccurate assumptions and a broad variety of other risks and uncertainties, including some that are known and some that are not. No forward-looking statement can be guaranteed and actual future results may vary materially. The Company does not assume the obligation to update any forward-looking statement. One should carefully evaluate such statements in light of factors described in the Company’s filings with the SEC, especially the Company’s Annual Report on Form 10-K and the Company’s Quarterly Reports on Form 10-Q. In various filings the Company has identified important factors that could cause actual results to differ from expected or historic results. One should understand that it is not possible to predict or identify all such factors. Consequently, the reader should not consider any such list to be a complete list of all potential risks or uncertainties.

The following discussion is presented on a consolidated basis, and analyzes our financial condition and results of operations for the three and nine months ended September 30, 2015 and 2014. Unless the context indicates or suggests otherwise, reference to “we”, “our”, “us” and the “Company” in this section refers to the consolidated operations of Solar Power, Inc. and its subsidiaries, as defined in Note 1 — Description of Business and Basis of Presentation to the Condensed Consolidated Financial Statements.

Overview

We are a global provider of PV solutions for business, residential, government and utility customers and investors. We provide a full spectrum of EPC services to third party project developers, as well as develop, own and operate solar projects that sell electricity to the grid in multiple countries, including China, the U.S., the U.K., Panama, Greece, Japan and Italy. Prior to 2014, we were primarily engaged in providing EPC services to developers in the U.S. We were also engaged in the development, manufacture and marketing of a variety of PV modules, the key components of solar parks that convert sunlight into electricity, and balance-of-system components, including our in-house brand. We have discontinued our manufacturing business and liquidated our research and development function. Starting from 2014, we expanded our full spectrum EPC service business to China, where we provided comprehensive and quality services to large solar projects in China. In addition, we commenced our global project development business by ramping up our portfolio of global solar projects, including projects that we plan to hold in the long term and derive electricity generation revenue from under our IPP model, and projects that we plan to sell in the future when we are presented with attractive opportunities under our build-and-transfer model, or BT model. Solar projects in our current portfolio include projects at all stages of development, including projects in operation, projects under construction and projects in pipeline. We grow our project portfolio primarily through acquisitions and act as a secondary developer for the projects we acquire which are under construction or in pipeline at the time they are added to our portfolio.

As a market innovation, in early 2015, the platform of www.solarbao.com, primarily targeting retail investors residing in China and a first-of-its-kind online energy e-commerce and investment platform, was launched by Solar Energy E-Commerce (Shanghai) Limited, or Solar Energy E-Commerce. Our PRC subsidiary, Yan Hua Internet Technology (Shanghai) Co., Ltd., has entered into a series of contractual arrangements with Solar Energy E-Commerce and its shareholders. Legal enforceability of these contractual arrangements has not been established and we are in the process of establishing a new corporate structure for the e-commerce business under which this platform will be migrated into a newly-established domestic company and one of our PRC subsidiaries will enter into a new set of contractual arrangements with the domestic company. We expect to be able to consolidate the financial results of the newly-established domestic company as a variable interest entity in our financial statements. This platform enables China-based individual and institutional investors to purchase PV-based investments and enables retail customers to purchase solar kits should they plan on building DG projects. Aside from being an independent revenue generating business, this e-commerce and investment platform is also being utilized by us as a financing channel for our DG projects. As of November 13, 2015, there were approximate 1,893,803 registered users with 1,089,556 active customer accounts with approximately $223 million fulfilled orders of PV-based investment products on this platform.

Critical Accounting Policies and Estimates

For a description of our critical accounting policies and estimates, please refer to the “Critical Accounting Policies and Estimates” section of our Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our Annual Report on Form 10-K, as amended, for the year ended December 31, 2014. There have been no material changes in any of our critical accounting policies and estimates during the nine months ended September 30, 2015.

Results of Operations

Three and nine months ended September 30, 2015, as compared to three and nine months ended September 30, 2014

Net sales

Net sales were $47.3 million and $22.6 million for the three months ended September 30, 2015 and 2014, respectively, an increase of $24.7 million, or 109.3%. Net sales were $107.2 million and $32.6 million for the nine months ended September 30, 2015 and 2014, respectively, an increase of $74.6 million, or 228.8%. The increase in net sales for the three and nine months ended September 30, 2015 over the comparative period was primarily due to: (i) our successful expansion into the China market resulting in the EPC revenue generated from China operations, (ii) the BT revenue generated from UK project and (iii) the distribution revenue generated by our subsidiary Solar Juice in Australia. We generated revenue from the provision of EPC services to a 30.0 MW DG solar project in Zhongwei County, Ningxia Autonomous Region, China, or the Zhongwei Project; a 30.0 MW DG solar project in Alashan County, Inner Mongolia Autonomous Region, China, or the Alashan Project; a 20.0 MW DG solar project in Ulanqab, Inner Mongolia Autonomous Region, China, or the Ulanqab Project and a 10.0 MW DG solar project in Alashan County, Inner Mongolia Autonomous Region, China, or the Zuoqi Project, in the aggregate amount of $21.0 million during the three months ended September 30, 2015, and $40.0 million during the nine months ended September 30, 2015. We generated BT revenue from a 9.5 MW grange farm project in UK, in the amount of $16.1 million during the nine months ended September 30, 2015. We generated distribution revenue by our subsidiary Solar Juice in Australia, in the amount of $15.8 million during the three months ended September 30, 2015, and $20.6 million during the nine months ended September 30, 2015.

Cost of goods sold

Cost of goods sold was $40.8 million (86.3% of net sales) and $17.8 million (78.8% of net sales) for the three months ended September 30, 2015 and 2014, respectively, an increase of $23.0 million, or 129.2%. Cost of goods sold was $90.1 million (84.0% of net sales) and $27.0 million (82.8% of net sales) for the nine months ended September 30, 2015 and 2014, respectively, an increase of $63.1 million, or 233.7%. The increase in cost of goods sold was in line with our expansion of business operations in China for the provision of EPC services to solar projects located in China, the BT services in UK and the distribution transactions in Australia, mainly including costs of goods sold for the Zhongwei Project, the Alashan Project, the Ulanqab Project, the Zuoqi Project, the grange farm project, and the distribution of PV related products by Solar Juice, in the aggregate amount of $32.5 million for the three months ended September 30, 2015 and $67.0 million for the nine months ended September 30, 2015.

Gross margins were 13.7% and 21.2% for the three months ended September 30, 2015 and 2014, respectively. Gross margins were 16.0% and 17.2% for the nine months ended September 30, 2015 and 2014, respectively. The decrease in gross margin for the three and nine months ended September 30, 2015 over that of the comparative period was due to higher revenue contribution from BT services and distribution transactions, which had lower margins as compared with EPC business.

General and administrative expenses

General and administrative expenses were $17.2 million (36.4% of net sales) and $2.1 million (9.3% of net sales) for the three months ended September 30, 2015 and 2014, respectively, an increase of $15.1 million, or 719.0%. General and administrative expenses were $67.1 million (62.6% of net sales) and $4.2 million (12.9% of net sales) for the nine months ended September 30, 2015 and 2014, respectively, an increase of $62.9 million, or 1,497.6%. Our general and administrative expenses during the three months ended September 30, 2015 mainly consisted of the stock-based awards to our management, payroll expenses, professional service fee such as legal and audit fees, and allowance for doubtful accounts, in the amount of $1.6 million, $6.1 million, $2.2 million and $5.1 million, respectively. Our general and administrative expenses during the nine months ended September 30, 2015 mainly consisted of the stock-based awards to our management, payroll expenses, professional service fee such as legal and audit fees, and allowance for doubtful accounts, in the amount of $35.8 million, $10.7 million, $8.7 million and $5.1 million, respectively. The increase in general and administrative expenses for the three and nine months ended September 30, 2015 over the comparative period was in line with our business expansion during the current period.

35

Sales, marketing and customer service expenses

Sales, marketing and customer service expenses were $5.8 million (12.3% of net sales) and $0.7 million (3.1% of net sales) for the three months ended September 30, 2015 and 2014, respectively, an increase of $5.1 million, or 728.6%. Sales, marketing and customer service expenses were $18.2 million (17.0% of net sales) and $1.0 million (3.1% of net sales) for the nine months ended September 30, 2015 and 2014, respectively, an increase of $17.2 million, or 1,720.0%. Our sales, marketing and customer service expenses during the three months ended September 30, 2015 mainly consisted of advertising expenses and payroll expenses for marketing personnel, in the amount of $4.4 million and $1.0 million, respectively. Our sales, marketing and customer service expenses during the nine months ended September 30, 2015 mainly consisted of advertising expenses and payroll expenses for marketing personnel, in the amount of $10.7 million and $4.5 million, respectively. The increase in sales, marketing and customer service expenses for the three and nine months ended September 30, 2015 over the comparative period was in line with our business expansion during the current period.

Interest expense

Interest expense was $3.1 million and $0.9 million, respectively, for the three months ended September 30, 2015 and 2014. Interest expense was $7.0 million and $2.1 million, respectively, for the nine months ended September 30, 2015 and 2014. We expect that interest expense will continue to fluctuate in the future depending on the amounts and relevant interest rates of debt financing utilized in our operations.

Interest income

Interest income was $0.3 million and $0.2 million for the three months ended September 30, 2015 and 2014, respectively. Interest income was $1.9 million and $1.0 million for the nine months ended September 30, 2015 and 2014, respectively. Interest income represents income earned from bank deposits, short-term investments and notes receivable.

Income tax expense

Our income tax expense was negative $0.8 million and $0.9 million for the three months ended September 30, 2015 and 2014, respectively. Our income tax expense was $0.5 million and $0.9 million for the nine months ended September 30, 2015 and 2014, respectively. Our effective income tax rate for the three months ended September 30, 2015 and 2014 was 2.5% and negative 12.9%, respectively. Our effective income tax rate for the nine months ended September 30, 2015 and 2014 was negative 0.6% and negative 9.9%, respectively. For both 2015 and 2014, we expect to generate taxable income in certain jurisdictions while experiencing an overall worldwide loss. The negative rate for the nine months ended September 30, 2015 is a result of the tax liability of certain profit generating subsidiaries of ours in jurisdictions that cannot be offset by losses making subsidiaries in certain other jurisdictions.

Item 3. Qualitative and Quantitative Disclosures About Market Risk

Pursuant to Item 305(e) of Regulation S-K, the Company, as a smaller reporting company, is not required to provide the information required by this item.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation and under the supervision of our principal executive officer and our principal financial officer, reviewed and evaluated the effectiveness of the design and operation of our disclosure controls and procedures, as of September 30, 2015 for the interim period covered by this report, as required by Securities Exchange Act Rule 13a-15, and concluded that our disclosure controls and procedures are not effective to ensure that information required to be disclosed in our reports filed with the Securities and Exchange Commission pursuant to the Securities Exchange Act of 1934 is accumulated and communicated to management timely, including our principal executive officer and principal financial officer. Based on such an evaluation, our Chief Executive Officer and Chief Financial Officer concluded the Company’s disclosure controls and procedures were not effective as of the end of such period. In making this conclusion, the Company considered, among other factors, the previously identified material weaknesses as described in the Company’s Annual Report on Form 10-K, as amended, for the year ended December 31, 2014 related to the application of generally accepted accounting principles to material complex and non-routine transactions as well as the lack of appropriate resources for appropriate segregation of duties.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

22. Commitments and Contingencies

Commitments

Guarantee — on December 22, 2009, in connection with an equity funding of STP related to the Aerojet 1 solar development project, the Company along with STP’s other investors entered into a Guaranty (“Guaranty”) to provide the equity investor, Greystone Renewable Energy Equity Fund (“Greystone”), with certain guarantees, in part, to secure investment funds necessary to facilitate STP’s payment to the Company under the EPC. Specific guarantees made by Solar Power, Inc. include the following in the event of the other investors’ failure to perform under the operating agreement:

• Operating Deficit Loans — the Company would be required to loan Master Tenant or STP monies necessary to fund operations to the extent costs could not be covered by Master Tenant’s or STP’s cash inflows. The loan would be subordinated to other liabilities of the entity and earn no interest; and

• Exercise of Put Options — At the option of Greystone, the Company may be required to fund the purchase by Managing Member of Greystone’s interest in Master Tenant under an option exercisable for 9 months following a 63-month period commencing with operations of the Facility. The purchase price would be equal to the greater of the fair value of Greystone’s equity interest in Master Tenant or $1,000. This option has been exercised on December 30, 2014 and this guarantee has been released accordingly.

The Company has recorded on its Condensed Consolidated Balance Sheet the guarantees of $60 and $71 at September 30, 2015 and December 31, 2014. These amounts, less related amortization, are included in accrued liabilities. These guarantees for the Aerojet 1 project are accounted for separately from the financing obligation related to the Aerojet 1 project because they are with different counterparties.

Financing Obligation — the guarantees associated with Aerojet 1 constitute a continuing involvement in the project. While the Company maintains its continuing involvement, it will apply the financing method and, therefore, has recorded and classified the proceeds received of $9,959 and $10,911 from the project in financing and capital lease obligations as of September 30, 2015 and December 31, 2014, respectively. At September 30, 2015 and December 31 2014, $8,948 and $10,092, respectively, were recorded as noncurrent Financing and capital lease obligations, with $1,011 and $819 recorded as other current liabilities.

Performance Guaranty — on December 18, 2009, the Company entered into a 10-year energy output guaranty related to the photovoltaic system installed for STP at the Aerojet 1 facility in Rancho Cordova, CA. The guaranty provided for compensation to STP’s system lessee for shortfalls in production related to the design and operation of the system, but excluding shortfalls outside the Company’s control such as government regulation. The Company believes that the probability of shortfalls is unlikely and if they should occur they would be covered under the provisions of its current panel and equipment warranty provisions. At September 30, 2015 and December 31 2014, there continues to be no charges against the Company’s reserves related to this performance guaranty.

Product Warranties — The Company offer the industry standard warranty up to 25 years for its PV panels and industry standard five to ten years on inverter and balance of system components. Due to the warranty period, the Company bear the risk of extensive warranty claims long after the Company has shipped product and recognized revenue. In the Company’s cable, wire and mechanical assemblies business, the Company’s historically warranty claims have not been material. In the Company’s solar PV business, the greatest warranty exposure is in the form of product replacement.

During the quarter ended September 30, 2007 and continuing through the fourth quarter of 2010, the Company installed own manufactured solar panels. Other than this period, the Company only installed panels manufactured by unrelated third parties as well as the Company’s principal shareholder and formerly controlling shareholder, LDK. Certain PV construction contracts entered into during the recent years included provisions under which the Company agreed to provide warranties to the buyer. As a result, the Company recorded the provision for the estimated warranty exposure on these contracts within cost of sales. Since the Company do not have sufficient historical data to estimate its exposure, the Company have looked to its own historical data in combination with historical data reported by other solar system installers and manufacturers. Due to the absence of historical material warranty claims, the Company have not recorded a material warranty accrual related to solar energy systems as of September 30, 2015 and December 31, 2014.

Operating leases — The Company leases facilities under various operating leases, some of which contain escalation clauses, which expire through 2020. The Company also leases vehicles under operating leases. Rental expenses under operating leases included in the statement of operations were $550 and $120 for the three-month period ended September 30, 2015 and 2014 respectively and $1,905 and $236 for the nine-month period ended September 30, 2015 and 2014 respectively.

Future minimum payments under all of our non-cancelable operating leases are as follows as of September 30, 2015:

2015 (remaining three months)	$	973
2016		3,215
2017		1,857
2018		1,454
2019		902
2020		737
Thereafter		8,743
	$	17,881

Capital commitments — As of September 30, 2015 and December 31, 2014, the Company had capital commitments of approximately $85,813 and $59,354 respectively. The capital commitments were solely related to contracts signed with vendors for procurement of services or PV related products used for the construction of solar PV systems being developed by the Company.

The capital commitments as at balance sheet dates disclosed above do not include those incomplete acquisitions for investment and business as at balance sheet dates as the agreements could either be terminated unconditionally without any penalty or cancelable when the closing conditions as specified in the agreements could not be met. The occurrence of non-fulfillment of those closing conditions are not considered as remote.

Contingencies

From time to time, the Company is involved in various other legal and regulatory proceedings arising in the normal course of business. While the Company cannot predict the occurrence or outcome of these proceedings with certainty, it does not believe that an adverse result in any pending legal or regulatory proceeding, individually or in the aggregate, would be material to our consolidated financial condition or cash flows; however, an unfavorable outcome could have a material adverse effect on our results of operations for a specific interim period or year.

Earnings Per Share [Abstract]

Net Loss Per Share of Common Stock

21. Net Loss Per Share of Common Stock

Basic loss per share is computed by dividing income attributable to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted loss per share reflects the potential dilution of shares by adding other Common Stock equivalents, including Common Stock options, warrants, and restricted Common Stock, in the weighted average number of common shares outstanding for a period, if dilutive. Potentially dilutive shares are excluded from the computation if their effect is anti-dilutive. As a result of the net loss for the nine-month and three-month periods ended September 30, 2015 and 2014, there is no dilutive impact to the net loss per share calculation for the period.

The following table presents the calculation of basic and diluted net loss per share:

The Company derecognized the waived liabilities of $17,775 from its condensed consolidated balance sheet as of September 30, 2015 in accordance with the Settlement Agreement and the supplemental agreement since the Company had fully paid the settlement amount of $11,000.

1. Description of Business and Basis of Presentation

Description of Business

Solar Power, Inc. (“SPI”) and its subsidiaries (collectively the “Company”) is a provider of photovoltaic (“PV”) solutions for business, residential, government and utility customers and investors. The Company provides a full spectrum of engineering, procurement and construction services (“EPC”) to third party project developers, as well as develop, own and operate solar PV projects that sell electricity to the grid in multiple countries, including China, the U.S., the U.K., Panama, Greece, Japan and Italy.

Prior to 2014, the Company was primarily engaged in providing EPC services to developers in the U.S. Since 2014, the Company commenced its global project development business by ramping up its portfolio of global solar projects, including projects that the Company intends to hold in the long term and derive electricity generation revenue.

As of September 30, 2015, SPI’s major subsidiaries include Xinwei Solar Engineering and Construction (Suzhou) Co., Ltd. (“Xinwei Suzhou”), Xinyu Xinwei New Energy Co., Ltd. (“Xinyu Xinwei”), Sinsin Renewable Investment Limited (“Sinsin”), Gonghe County Xinte Photovoltaic Co., Ltd. (“Xinte”), SPI Renewables Energy (Luxembourg) Private Limited Company S.a.r.l. (formerly known as CECEP Solar Energy (Luxembourg) Private Limited Company (S.a.r.l.)), and Italsolar S.r.l, (collectively the “CECEP”), Solar Juice Pty Ltd (“Solar Juice”), SPI Energiebau Renewables GmbH (“SPI Energiebau”), SPI Energy Co., Ltd. (“SPI Energy”), Solarbao E-commerce (HK) Limited (“Solarbao E-commerce”), Jiangsu Solarbao Leasing Co., Ltd. (“Jiangsu Solarbao”), Yanhua Network Technology (Shanghai) Co., Ltd. (“Yanhua Network”), SPI Solar Japan G.K. and Solar Power Inc UK Service Limited. CECEP, Solar Juice were acquired by the Company in February and May 2015 respectively. CECEP owned and operated a number of PV plants in Italy. Solar Juice was engaged in the distribution of PV related products including solar panels in Australia. Refer to Note 4 for details of these acquisitions.

SPI Energy was incorporated by SPI as a wholly-owned subsidiary in the Cayman Islands in May 4, 2015. On May 11, 2015, SPI Energy initially filed a registration statement on Form F-4 in connection with seeking shareholder consent for the approval of certain agreements and plan of reorganization and related redomicile of SPI to the Cayman Islands. On November 5, 2015, SPI Energy filed registration statement amendment no. 5 on from F-4 in connection with such re-organization and related redomcile.

Solarbao E-commerce, Jiangsu Solarbao and Yanhua Network were incorporated by the Company in 2015 for raising funds from individual investors and leasing of solar panels through an online platform owned by Solar Energy E-Commerce (Shanghai) Limited (“Solar Energy”). Solar Energy was incorporated in China on December 8, 2014 by Xiaofeng Peng (“Mr. Peng”), Min Xiahou and Jing Liu, who are the chairman of the Company’s board of directors, deputy chairman of the Company’s board of directors and chief financial controller of the Company respectively. Solar Energy operates the “www.solarbao.com” e-commerce and investment platform which primarily targets retail customers residing in the PRC. On March 26, 2015, the Company, through Yanhua Network, entered into a series of contractual arrangements (“VIE Agreements”) with Solar Energy and its shareholders. The contractual arrangements include power of attorney, call option agreement, equity pledge agreement, and a consulting services agreement. As of the date of these condensed consolidated financial statements, the Company has not established the legal enforceability of these contractual agreements described above including the registration of the equity pledge agreement in the relevant government bureau in the PRC. Therefore, the financial results of Solar Energy could not be consolidated by the Company before the legal enforceability of the contractual agreements is established.

Through the on-line platform of Solar Energy, the Company has raised funds from individual investors, who need to register as a member on the platform, through certain on-line products launched by the Company since January 2015. Each on-line products launched on the platform are set with a targeted amount of funds in renminbi to be raised for that product, which is divided into units (“Investment Unit”) with unit value ranging from RMB16.7 to RMB200,000. Individual investors may subscribe for Investment Unit of these on-line products which are generally structured in the way of using the funds from individual investors to purchase solar module or PV related products (“Underlying PV Products”) for leasing to the PV project developers on PV project basis over a specified period. These PV projects may represent the Company’s self developed projects or third party developed projects. Investments made into each on-line product are subject to lock-up period, which ranges from nil to 1,080 days, depending on the terms of each on-line product. During the lock-up period, the individual investors could not transfer or redeem their subscribed Investment Units. After the lock-up period, individual investors are permitted either to transfer their investments in respect of the principal portion to other investors through the on-line platform or, for substantially all products launched, to request the Company to redeem their subscribed Investments Units. Any Investments Units so redeemed by the Company could be put on the on-line platform for re-sale to other investors. Once Investment Units are subscribed and funds are provided, individual investors are guaranteed by the Company with an minimum investment return for their investments, which ranges from an annual rate of 5.25% to 11.9% for the nine-month period ended September 30, 2015, and are also guaranteed for the repayment of funds principal at the end of the investment period by requesting the Company to redeem their investment units. Such redemption rights are granted by the Company for substantially all products launched. Any funds provided by individual investors without subscribing for any on-line products are not entitled to any interest.

For each investment into these On-line products by the individual investors with redemption rights granted by the Company, although a tri-party lease agreement is signed among the individual investors, the Company and the PV project developer with individual investors as legal lessor and the PV project developers as legal lessee, the Company is considered as the accounting lessor in substance because 1) the lease terms, rate of return on the investment funds from individual investors, the initial purchase price and the lease rental of the Underlying PV products payable by the PV developers and the purchase contract of the Underlying PV Products entered with manufacturer are negotiated and concluded by the Company without any involvement by the individual investors; and 2) individual investors are entitled to a minimum interest rate as return that are guaranteed by the Company in respect of their funds provided and does not take credit risk in respect of any default payment by the lessee nor risk of claim on the leased assets; 3) the Company is subject to the credit risk as a principal of the lease transaction and has unconditional commitment to return the funds to the individual investors and assume the title of the leased asset after the lock-up period. Based on the above, the individual investors purely provided funds (as lender) to finance the Company (as borrower) for its purchases of the Underlying PV Products for leasing to a solar PV developer in return for a fixed return. In this regard, lease accounting is adopted with the Company as lessor and third party PV developer as lessee for any Underlying PV Products purchased by the Company for leasing to third party project developers. For those on-line products of which the PV project developer (i.e. the legal lessee) is one of SPI’s subsidiaries, the related leasing transactions are eliminated in the condensed consolidated financial statements. Regardless as to whether a SPI’s subsidiaries or a third party PV developer is deemed to be the accounting lessor, all interest bearing funds provided by individual investors are recorded on the condensed consolidated balance sheet as either short term borrowings or long term borrowings included in other noncurrent liability. Funds provided with the lock-up period over one year are classified as long term borrowings and funds with a lock-up period of less than one year are classified as short-term borrowings. Funds that are provided without any on-line products subscribed are non-interest bearing and are reclassified as amount due to individual investors under other current liabilities (See Note 15-Other liabilities).

During the nine-month period ended September 30, 2015, substantially all of the on-line products launched through the on-line platform are related to the Company self-owned PV projects with SPI’s subsidiaries being the lessee. For those on-line products of which the lessee is third party developer, such leases are classified as finance lease in the Company’s condensed consolidated financial statements.

In connection with the launch of the above financing and leasing products, the Company issued to certain third party vendors, Jiangxi LDK Solar Hi-Tech Co., Ltd. (“LDK Jiangxi”) and Suzhou Liuxin Industry Ltd. (“Liuxin”) coupons with total face value of $1,998, nil and nil during the three-month period ended September 30, 2015 and $6,860, $779 and $582 respectively during the nine-month period ended September 30, 2015. Both LDK Jiangxi and Liuxin are related parties of the Company. These coupons are freely transferable between holders but could not be redeemed in cash. Each coupon has an expiry date for redemption. Prior to the expiry date, when the holder subscribe the on-line products through the on-line platform owned by Solar Energy described above, the holders could redeem the coupons and reduce the original purchase price for the on-line products by the face value of the coupons.

For the coupons issued to the third party vendors and LDK Jiangxi, the Company is entitled to the face value in cash or, if mutually agreed between the Company and LDK Jiangxi or between the Company and the relevant third party vendor, to apply the face value as of offset to outstanding accounts payables to these counterparties. Accordingly, the face values of these coupons, totaling $7,639, were recorded as other receivables upon issuance of the coupons. During the nine-month period ended September 30, 2015, other receivable balances related to such coupons totaling $6,854 and $779 were setoff against the related accounts payable balances when mutual agreement with the counterparties had been reached and the legal right to setoff had been established. As of September 30, 2015, other receivable balances due from third party vendors arising from the coupons amounted to $6.

The coupons issued to Liuxin were originally intended for promotional purposes. The face values of these coupons, totaling $582, were therefore recorded as selling expense in the three-month period ended March 31, 2015 because there is no written agreement for the settlement of these coupons. During the three-month period ended September 30, 2015, the Company received full payment of $582 from Liuxin for the face value of the coupons issued and therefore recorded the amounts received as a reduction of selling expenses.

The face values of the coupons are recorded in other payables upon issuance, which were reclassified as the Company’s borrowings when the coupons are redeemed through the purchase of on-line products. As of September 30, 2015, all coupons issued to these counterparties had been redeemed.

In order to promote the above on-line products on the platform, the Company offered, from time to time, discount from 5% to 20% on the unit value for Investment Units subscribed by individual investors. The discount offered for on-line products subscribed by individual investors is amortized as interest expense using the effective interest rate method through the end of the lock-up period, which is the earliest date that the Company could be required to repay the unit value in respect of the investment made by individual investors. The Company has also started a series of promotion activities targeting on new member (i.e. new individual investors). During the nine-month period ended September 30, 2015, the Company launched two series of such promotion program pursuant to which any new member registered on-line during the promotion period could be paid back with RMB17.26 in 3 days or RMB9.86 immediately by paying RMB1 into their newly opened account maintained with the Company. By participating in this program, these new members are not obliged to subscribe for any on-line products at that time or in the future in order to get the amount of RMB17.26 in 3 days or RMB9.86 immediately. The difference between the amount paid by new members and the amount to be paid back by the Company under this promotion activity is recorded as selling expenses as incurred, which amounted to $2,238 and $947 during the nine-month and three-month periods ended September 30, 2015. In addition, the Company launched a referral program pursuant to which existing members successfully referred any new member to register a newly opened account on-line and acquire the online products will be entitled to a referral fee of RMB 40 plus 0.55% to 0.8% of the fund principal raised from the newly referred members from time to time in the first two months after the opening of the new account. Such referral fee is recorded as selling expenses as incurred, which amounted to $559 and $389 during the nine-month and three-month periods ended September 30, 2015.

Through its on-line platform, Solar Energy serves as a service agent of the Company to collect funds from and repay funds to individual investors. For the funds collected and repaid through Solar Energy prior to June 17, 2015, the Company made settlement with Solar Energy on a regular basis. From June 17, 2015 onwards, the Company has made repayment of borrowings to individual investors directly while Solar Energy still continues to collect the funds from individual investors and settle with the Company within 2 weeks. For the service provided through the on-line platform, Solar Energy generally charges the Company commission fee at 1% of the fund principal invested into the on-line products by individual investors (see Note 23 — Related Party Transactions) except for those resale of redeemed on-line products by the Company where no commission will be charged to the Company. Such commission fees were recorded as interest expenses on the condensed consolidated statement of operation.

During the nine-month period ended September 30, 2015, the total fund raised from individual investors through Solar Energy amounted to $95,665, of which $8,199 was settled by the coupon issued by the Company to the third party vendors and two related party without cash inflow as described above and $85,495 had been received by the Company from Solar Energy as of September 30, 2015. The Company recorded the remaining funds to be received from Solar Energy in other receivable- due from related party on the condensed consolidated balance sheet as at September 30, 2015, after the reduction of its commission fee of $276 (See Note 23 — Related Party Transactions). During the nine-month period ended September 30, 2015, the funds redeemed to individual investors through Solar Energy amounted to $19,237, of which $18,801 had been repaid by the Company to Solar Energy as of September 30, 2015. The Company recorded the remaining redeemed amounts to be paid to Solar Energy of $436 in other liabilities-due to related party on the condensed consolidated balance sheet as at September 30, 2015. Also, the Company repaid $38,830 directly to individual investors during the nine-months period ended September 30, 2015. In the condensed consolidated statement of cash flows for the nine-month period ended September 30, 2015, the Company recorded the cash received from Solar Energy of $85,219 in relation to funds provided by individual investors in the line item of “Proceeds from loans on solarbao platform through Solar Energy”, and the cash of $57,631 for repayment to individual investors in the line item of “Repayments of loans on solarbao platform directly or through Solar Energy” under financing activities.

They should be read in conjunction with the financial statements and related notes to the financial statements of Solar Power, Inc. for the years ended December 31, 2014 and 2013 appearing in Solar Power, Inc.’s Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 31, 2015. The Company’s September 30, 2015 and 2014 unaudited interim condensed consolidated financial statements on Form 10-Q have been prepared pursuant to the rules and regulations of the SEC for smaller reporting companies and include the accounts of Solar Power, Inc. and its subsidiaries.

Certain information and note disclosures normally included in the annual financial statements on Form 10-K have been condensed or omitted pursuant to those rules and regulations, although the Company’s management believes the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting of normal recurring adjustments and reclassifications, necessary to present fairly the Company’s consolidated financial position, results of operations and cash flows for all periods presented have been reflected herein. The Company’s financial position, operating results, cash flows and trends in these unaudited condensed consolidated financial statements are not necessarily indicative of future results that may be expected for any other interim period or for the full year.

The preparation of unaudited interim condensed consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements as well as the reported amounts of revenues and expenses during the reporting period. Significant accounting estimates used in the preparation of the Company’s consolidated condensed financial statements include: allowance made for doubtful accounts receivable, inventory write-downs, the estimated useful lives of long-lived assets, the impairment of goodwill, long-lived assets and project assets, fair value of derivative asset/liability, valuation allowance of deferred income tax assets, accrued warranty expenses, the grant-date fair value of share-based compensation awards and related forfeiture rates, and fair value of financial instruments. Actual results could differ from those estimates upon subsequent resolution of identified matters.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), to clarify the principles of recognizing revenue and create common revenue recognition guidance between U.S. GAAP and International Financial Reporting Standards. An entity has the option to apply the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this standard recognized at the date of initial application. ASU 2014-09 is effective for fiscal years and interim periods within those years beginning after December 15, 2017, and early adoption is permitted for periods beginning after December 15, 2016. The Company has not determined which transition method it will adopt, and is currently evaluating the impact of this standard on its consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements — Going Concern (Subtopic 205- 40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which requires management to evaluate, at each annual and interim reporting period, whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued and to provide related disclosures. ASU 2014-15 is effective for the Company for the fiscal year ending December 31, 2016 and for interim periods thereafter. The Company is currently evaluating the impact of this standard on its consolidated financial statements.

In January 2015, the FASB issued ASU No. 2015-01, Income Statement — Extraordinary and Unusual Items (Subtopic 225- 20), which eliminates the concept of reporting for extraordinary items. ASU 2015-01 is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning on January 1, 2016. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

On February 18, 2015, the FASB issued ASU No. 2015-02, Consolidation, which reduces the number of consolidation models and simplifies the current standard. Entities may no longer need to consolidate a legal entity in certain circumstances based solely on its fee arrangements when certain criteria are met. ASU 2015-02 reduces the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity. ASU 2015-02 is effective for the Company’s fiscal year ending December 31, 2016. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, Interest — Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 is effective for the Company on a retrospective basis on January 1, 2016. Early adoption is permitted, but only for debt issuance costs that have not been reported in financial statements previously issued or available for issuance. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. ASU 2015-11 applies to inventory that is measured using the first-in, first-out (“FIFO”) or average cost method and requires measurement of that inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

11. Investment in EnSync, Inc.

On April 17, 2015, the Company and EnSync, Inc. (formerly known as ZBB Energy Corporation) (“ENS”), a Wisconsin corporation, entered into a Securities Purchase Agreement pursuant to which ENS will issue and sell to the Company for an aggregate purchase price of $33,390 which is to be settled in cash, a total of (i) 8,000,000 shares (the “Purchased Common Stock”) of ENS’s common stock based on a purchase price per common share of $0.6678 and (ii) 28,048 shares of the ENS’s convertible preferred stock (the “Convertible Preferred Stock”) which are convertible into an aggregate of 42,000,000 shares of common stock, representing a purchase price of $0.6678 per common stock on an as-if converted basis, over a four-year period with 25% of issued Convertible Preferred Stock became convertible in each of the next four years if the Company meets certain conditions relating to the Company’s purchases of minimum megawatt of solar related products from ENS in each of the next four years as set out in the Securities Purchase Agreement. The purchase prices of the products are not fixed or determinable in the agreements, but ENS shall not at any time sell a lower quantity of the products under similar terms and conditions to other buyers at prices below those provided to the Company. The conversion is subject to adjustment for stock splits, stock dividends, and other designated capital events. ENS also entitles the Company to acquire 50,000,000 shares of ENS’s common stock (the “Warrant”) for an aggregate amount of $36,729, or $0.7346 per share, subject to adjustment for stock splits, stock dividends, and other designated capital transactions. The consummation of the Securities Purchase Agreement is subject to certain closing conditions.

ENS develops, licenses, and manufactures innovative energy management systems solutions serving the commercial and industrial building, utility and off-grid markets.

On July 13, 2015, all closing conditions relating to the Securities Purchases Agreement was met. The Purchased Common Stock, Convertible Preferred Stock and Warrant have been issued to the Company.

The Purchased Common Stock represents approximately 17% of the outstanding common stock of ENS as at July 13, 2015. Additionally, assuming the full conversion of the Convertible Preferred Stock (and that no other shares of common stock of ENS are issued), the Company would own greater than a majority of the outstanding common stock of ENS.

The Company also entered into a supply agreement with ENS pursuant to which ENS will sell and the Company will purchase certain products offered by ENS from time to time, including energy storage systems for solar projects (the “Supply Agreement”). Convertibility of the Convertible Preferred Stock is dependent upon the Company making purchases of and payments for energy storage systems under the Supply Agreement as follows: the first one-fourth (the “Series C-1 Preferred Stock”) of the Purchased Preferred Shares only become convertible upon the receipt of final payment for 5 megawatts (“MW”) that are purchased by SPI in accordance with the Supply Agreement; the second one-fourth (the “Series C-2 Preferred Stock”) only become convertible upon the receipt of final payment for an aggregate of 15 MW worth of the Supply Agreement; the third one-fourth (the “Series C-3 Preferred Stock”) only become convertible upon the receipt of final payment for an aggregate of 25 MW worth of the Supply Agreement; and the last one fourth (the “Series C-4 Preferred Stock”) only become convertible upon the receipt of final payment for an aggregate of 40 MW worth of the Supply Agreement. The Convertible Preferred Stock will not become convertible unless the payment for the Supply Agreement is received. If the Company complies with the provisions of the Supply Agreement, it will make sufficient purchases for each tranche of the Convertible Preferred Stock to vest and become convertible over the next four years. However, the Convertible Preferred Shares will become convertible at any time when the relevant payments are received by ENS for the specified purchases, even if the payments are made later or earlier than the schedule set out in the Supply Agreement.

The Convertible Preferred Stock possesses no voting rights except as required by law or for certain matters specified in the agreement. The Convertible Preferred Stock are perpetual, are not eligible for dividends, and are not redeemable. Besides, so long as any shares of Convertible Preferred Stock are outstanding, ENS may not pay dividends on its common stock and may not redeem more than $100 in common stock per year. The Convertible Preferred Stock has a liquidation preference equal to the greater of $28,048 and the distribution of the entire assets on an as-converted basis.

The Warrant vests and becomes exercisable once the Company purchases and pays for 40 MW of the Supply Agreement, and will not vest or become exercisable if those purchases and payments do not occur before the termination of the Warrant, which will occur, whether the Warrant has vested or not, on July 13, 2019. Prior to exercise, the Warrant provides the Company with no voting rights. The Warrant may not be partially exercised. As the closing price of ENS’s common stock at September 30, 2015 was below the exercise price of the Warrant, the Warrant was out-of-the-money at that date.

In connection with the Securities Purchase Agreement, the Company entered into a governance agreement with ENS (the “Governance Agreement”). Under the Governance Agreement, the Company is entitled to nominate one director to the board of directors of ENS for so long as the Company holds at least 10,000 convertible preferred shares or 25 million shares of common stock or common stock equivalents (the “Requisite Shares”). Additionally, for so long as the Company holds the Requisite Shares (1) following the time at which the Series C-2 Preferred Stock shall have become convertible in full, SPI shall be entitled to nominate a total of two directors and (2) following the time at which the Series C-3 Preferred Stock shall have become convertible in full, SPI shall be entitled to nominate a total of three directors. Provided in no event shall the Company be entitled to nominate a number of directors to the Board that would represent a percentage of the Board greater than the percentage determined by dividing the number of Common Stock Equivalents held by the Company by the sum of (A) the total shares of ENS’s Common Stock outstanding and (B) the number of shares of Common Stock into which the Preferred Stock held by the Company is convertible.

The Company accounts for this investment in the Purchased Common Stock under the equity method. The Company includes its proportionate share of net earnings or loss attributable to common stockholders and other comprehensive income in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The Company accounts for the investment in the Convertible Preferred Stock as other investment carried at cost in the Condensed Consolidated Balance Sheets. The Company accounts for the Warrant as a derivative asset at fair value which is included in Derivative asset, noncurrent in the Condensed Consolidated Balance Sheet as of September 30, 2015. The derivative asset was initially recorded at its fair value of $16,947. The change in fair value of $10,793 was recorded under Other income-Change in market value of derivative asset/liability in the Condensed Consolidated Statement of Operations for the nine-month and three-month periods ended September 30, 2015. The total consideration of $33,390 less the fair value of warrants as of July 13, 2015 was allocated, based on relative fair value, between the investments in the Purchased Common Stock and investment in the Convertible Preferred Stock, which were initially recorded at $3,244 and $13,199, respectively.

	September 30, 2015

(a) Acquisition of CECEP

On January 15, 2015, SPI and SPI China (HK) Limited, a wholly-owned subsidiary of SPI, entered into a stock purchase agreement (the “Stock Purchase Agreement”) with CECEP Solar Energy Hong Kong Co., Limited (“CECEP HK”). Pursuant to the Stock Purchase Agreement, SPI China (HK) Limited agreed to purchase from CECEP HK 100% of issued and outstanding shares of capital stock of CECEP owned by CECEP HK.

Through its respective wholly and non-wholly owned subsidiaries in Italy, CECEP are engaged in the development, acquisition, management, and operation of energy projects and facilities dedicated to the production of alternative energy sources and the facilitation of the distribution, supply and sale of such alternative energy power, through four photovoltaic plants with a total capacity of 4.3 MW in Italy.

The purchase consideration of CECEP consists of cash and SPI’s common stock. In addition to the purchase considerations, the Company is also required to settle the borrowings in the amount of Euro 7,870 ($8,967) due to CECEP HK on behalf of CECEP (“Payable Settlement”). Including the Payable Settlement, the Company needed to settle cash of Euro 3,125 ($3,561) (“Cash Settlement”) and 5,722,977 shares of SPI’s common stock. The Cash Settlement was fully settled in the form of several installments in March and April 2015. The Stock Consideration was settled on January 30, 2015 by the Company, and the common stock was subject to a three-month lockup period as agreed in the Stock Purchase Agreement. The acquisition was consummated on February 16, 2015 upon completion of all closing conditions. All cash consideration has been settled according to the predetermined payment schedule.

The Company issued 5,722,977 shares of its Common Stock to CECEP HK on January 30, 2015. The fair value of the Stock Consideration was determined to be $8,269, which was based on the closing market price of SPI’s common stock on the acquisition date of February 16, 2015, with adjustments for the lockup period and other factors.

The acquisition has been accounted for under ASC 805 Business Combinations. The Company made estimates and judgments in determining the fair value of acquired assets and liabilities, based on management’s experiences with similar assets and liabilities with the assistance from an independent valuation firm. The allocation of the purchase price is as follows:

	USD
Identifiable assets acquired and liabilities assumed
Cash and cash equivalents		1,389
Accounts receivable		394
Other receivable		1,137
Property, plant and equipment		11,041
Deferred tax asset		180
Accounts payable		(244	)
Income tax payable		(130	)
Other accrued liabilities		(1,234	)
Loans payable		(884	)
Identifiable net assets acquired (a)		11,649
Consideration and Payment Settlement (b)		11,830
Non-controlling interests (c)		1,236
Goodwill (b+c- a)		1,417

During the period from the acquisition date to September 30, 2015, CECEP contributed revenue of $1,005 and earnings of $197 to the Company’s consolidated results.

Goodwill primarily represents the expected synergies from combining operations of the Company and CECEP, which are complementary to each other, and any other intangible benefits that would accrue to the Company that do not qualify for separate recognition.

(b) Acquisition of Solar Juice

On March 31, 2015, SPI China (HK) Limited, a wholly-owned subsidiary of SPI, entered into a share purchase agreement (“Purchase Agreement”) with Andrew Burgess, a citizen of Australia as trustee on the terms of the Burgess Absolutely Entitled Trust, Rami Fedda, a citizen of Australia as trustee on the terms of the Fedda Absolutely Entitled Trust, and Allied Energy Holding Pte Ltd, a company incorporated in Singapore and associated with Simon Tan, a citizen of Singapore (collectively, the “Solar Juice Sellers”). Pursuant to the Purchase Agreement, SPI China (HK) Limited agreed to acquire from Solar Juice Sellers 80% of equity interest in Solar Juice Pty Ltd (“Solar Juice”), an Australian proprietary company. The acquisition was consummated on May 28, 2015 upon completion of all closing conditions.

Solar Juice is engaged in the distribution of solar photovoltaic panels, solar inverters and other energy efficient solutions, both domestically and internationally.

The purchase consideration consisted of 14,073,354 shares of the Company’s common stock (“Consideration”). The fair value of the Consideration was determined to be $15,578, which was based on the closing market price of the Company’s common stock on the acquisition date of May 28, 2015, with adjustment for the lockup period and other factors.

The acquisition has been accounted for under ASC 805 Business Combinations. The Company made estimates and judgments in determining the fair value of acquired assets and liabilities, based on management’s experiences with similar assets and liabilities with the assistance from an independent valuation firm. The allocation of the purchase price is as follows:

	USD
Identifiable assets acquired and liabilities assumed
Cash and cash equivalents		1,037
Accounts receivable		6,124
Inventories, net		14,728
Prepaid expenses and other current assets		263
Other current assets		525
Intangible assets		4,579
Property, plant and equipment net		301
Deferred tax asset		295
Accounts payable		(10,934	)
Accrued liabilities		(534	)
Prepaid income tax		89
Advance from customers		(230	)
Short term borrowings		(4,305	)
Deferred tax liability		(1,889	)
Identifiable net assets acquired (a)		10,049
Consideration (b)		15,578
Non-controlling interests (c)		2,709
Goodwill (b+c- a)		8,238

During the period from the acquisition date to September 30, 2015, Solar Juice contributed revenue of $20,600 and losses of $673 to the Company’s consolidated results.

Solar Juice is one of the largest distributors of solar panels and inverters in Australia and have well established distribution channel in South East Asia. As a result of the acquisition of Solar Juice, the Company would be able to have immediate access to the solar PV market in Australia, New Zealand and South East Asia, which could enhance the Company’s development of PV projects in those markets. Goodwill primarily represents such expected synergies the Company obtained from the acquisition.

Pursuant to the Purchase Agreement, the Company was granted a call option by the Solar Juice Sellers to acquire remaining 20% equity interest in Solar Juice from them. The exercise price per share of the call option is to be determined based on Solar Juice’s earnings before interest, taxation, depreciation and amortization (“EBITDA”) per share for the year ending December 31, 2015 multiplied by six. The acquisition consideration will be settled with the Company’s common stock if the Company exercises the option. The number of shares to be issued by the Company will be determined by the share price on the exercise date. The call option will be expired on May 28, 2016. The call option meets the definition of a derivative. The Company initially recognized the call option at its fair value of $420 as a derivative asset in Other current assets on the consolidated balance sheet as of September 30, 2015 with gain of $4 and nil arising from the change in fair value recorded in the consolidated statement of operations for the nine-month and three-month periods ended September 30, 2015. The fair value measurement of this call option was further discussed in Note 13 — Fair value measurement.

Additionally, Solar Juice received a Notice to Produce Documents request from the Australian Customs Border Protection Service in relation to the tariff classification of certain imports, consistent with similar requests issued to other companies in the solar photovoltaic industry in October 2014. Whilst no official claim for payment has been made on Solar Juice by the Australian Customs Border Protection Service, Solar Juice has submitted an application for an internal review via the Tariff Advice mechanism in January 2015 and is awaiting responses from customs. Based on an internal review by management of the Company as well as external legal advice, Solar Juice considered no significant liability will arise and disclosed the contingency liability (not including any penalties or charges if any) amounting to US$700 as of May 28, 2015. Pursuant to the Purchase Agreement, tax liabilities arising for the period before the closing date of the acquisition will be indemnified by the Solar Juice Sellers. Therefore, the Company considered that no significant liability has been assumed in connection with this acquisition.

The convertible notes bore no interest, and might be partially or wholly converted into shares of the Company’s common stock at any time prior to maturity at the option of the investor. The convertible promissory notes was due and payable on June 11, 2016 and are reclassified as current liabilities as of September 30, 2015.

On June 15, 2015, the Company entered into a convertible promissory note purchase agreement with Vision Edge Limited (“Vision Edge”), whereby the Company agreed to sell and issue to Vision Edge convertible promissory note in an aggregate principal amount of $20,000 which could be converted into 7,407,410 Common Shares at a fixed conversion price of $2.70 unless adjusted for anti-dilution. The convertible notes bore no interest, and might be wholly converted into shares of the Company’s common stock at any time prior to maturity at the option of the investor. The commitment date of the convertible promissory note is on June 29, 2015. The convertible promissory note was due and payable on June 29, 2016. Also, as mentioned in Note 17 — Stock option, on June 15, 2015, the Company entered into option agreement with Vision Edge, whereby the Company agreed to grant Vision Edge an option to purchase from the Company a total of 7,407,410 Shares for an aggregate purchase price of $20,000, or $2.70 per share, prior to December 15, 2015. The above instruments issued to Vision Edge on June 15, 2015, including convertible promissory note and stock option, were accounted for as a bundled transaction. The proceeds from the issuance of convertible promissory note were allocated to the two elements based on the relative fair values of the convertible promissory note and the stock options at the time of issuance. There is no beneficial conversion feature in this convertible promissory note because the initial conversion price of US$ 2.66 per share after the proceeds are allocated to the option is greater than the fair value of the Company’s common stock on the commitment date of June 29, 2015. The convertible promissory note and stock options were initially recorded at $19,705 and $295, respectively, according to the allocation of the total proceeds. The discount of $295 of the convertible promissory note is amortized as interest expense using the effective interest rate method through the earliest demand payment date, i.e. June 29, 2016. The stock option was accounted for as an equity instrument and was recorded within equity.

Calwaii Projects

In 2014, the Company acquired solar PV assets, primarily including land use right and pre-contract costs relating to forty-three solar PV systems owned by Calwaii. During the nine-month period ended September 30, 2015, sales of four solar PV systems were consummated (see below). As of September 30, 2015 and December 31, 2014, incurred costs for PV solar systems under the Calwaii’s projects in Hawaii amounted to $23,570 and $23,943 respectively.

Solar Mountain Creek Parent LLC

Pursuant to a letter of intent dated November 10, 2014 and a sales agreement dated December 31, 2014, the Company agreed to sell the PV solar systems of this project upon its completion of construction at a consideration of $17,864. In July 2015, the Company entered into a supplemental agreement to extend the deadline of final completion to the end of 2015 and compensate the buyer up to $625. The compensation would be deducted from the consideration. Management assessed the recoverable amounts of this project asset and as a result the carrying amount of this project asset was written down to the recoverable amount of $17,239. The estimate of recoverable amount of this project asset was based on this asset’s fair value less costs of disposal, and the fair value was determined by reference to the quoted price from third party. The Company accounted for this sales transaction using the deposit method under ASC 360-20, Real Estate Accounting, and did not recognize any revenue and profit for this sales transaction for the year ended December 31, 2014 and the nine-month period ended September 30, 2015 as certain closing conditions as specified in the sales agreement had not been met and accordingly sales had not been consummated as of September 30, 2015.

RE Capital Projects

In April 2015, the Company entered into an interest purchase agreement with RE Capital Pte. Ltd. to acquire its 100% membership interest in seventeen PV project companies in Japan (“RE Capital companies”) at a consideration of $8,800 consisting of $3,300 cash and $5,500 worth of the Company’s common stock (See Note 18 — Stockholders’ Equity). RE Capital companies’ total assets and liabilities only included land and pre-contract cost related to solar projects of 52MWs in total. Additionally, RE Capital companies had not entered into any power generation contracts with any utilities companies. As a result, Management concluded that the acquisition of 100% managing member interest in RE Capital companies did not meet the definition of a business combination as the primary inputs (the solar plant, which had yet to be constructed) were not available on the acquisition date. As of September 30, 2015, the payment made and cost incurred of $8,123 in total up to September 30, 2015 were included and recorded as project assets.

During the nine-month periods ended September 30, 2015, the Company recognized sales revenue for the following projects:

Calwaii Projects

Pursuant to a sales agreement dated September 18, 2014, the Company agreed to sell four out of the thirty-nine PV solar systems of Calwaii’s project upon their completion of construction at a consideration of $5,860. The Company accounted for this sales transaction under ASC 360-20, Real Estate Accounting, and did not recognize any revenue and profit for this sales transaction for the year ended December 31, 2014 and three-month period ended March 31, 2015 as certain closing conditions, including but not limited to grid connection specified in the sales agreement, had not been met. As of June 30, 2015, all closing conditions had been met and sales had been consummated. Accordingly, the Company recognized revenue and cost for these solar projects of $5,860 and $5,850, respectively.

In the event the parties are unable to resolve the dispute by December 30, 2015, the parties shall submit the dispute to mediation. If the parties are unable to resolve the dispute through mediation, then either party may pursue any other remedies available at law or in equity. The Company are seeking damages from Hi-Kilowatts for the unpaid receivable and breach of the sales agreement. The parties are in the process of negotiating a settlement agreement.

Solar Park Development 3 Ltd

In June 2015, the Company entered into a shares sales agreement with Blackrock Income UK Holding Limited to transfer the 100% outstanding share of Solar Park Development 3 Ltd at a consideration of $16,088 (equivalent to GBP10,532), which owned a grid-connected solar project of 9.5 MW developed by the Company. The Company accounted for this sales transaction under ASC 360-20, Real Estate Accounting. As of June 30, 2015, all closing conditions specified in the shares sales agreement had been met and the Company recognized revenue and cost for this solar project of $16,088 and 14,854, respectively during the three-month period ended June 30, 2015. The receivable of $16,088 were fully settled by Blackrock Income UK Holding Limited in July 2015.

Project assets under development-Company expected to be project owner upon completion of construction are related to the following projects:

In late 2014, the Company entered into two EPC contracts with third-party projects owners under an arrangement pursuant to which there was mutual understanding between the Company and the respective project owners that the title and ownership of the PV solar power systems would transfer to the Company upon the completion of construction and grid connection of the PV systems under the EPC contracts by the Company. The PV solar systems were pledged to the Company, as part of the EPC contract terms, to secure the expected title transfer upon grid connection. In 2015, the Company entered into similar arrangement with two third-party project owners.

Unlike other EPC contracts which are accounted for in accordance with ASC 605, no revenue is recognized for these four EPC contracts as no revenue is expected to be realized or earned from the EPC contracts, which were signed to facilitate the construction of the related solar PV systems by the Company and secure the Company’s financial interests in these projects through the pledge of the related solar PV systems. Given the substance of the transactions, the mutual understanding reached between the Company and the third-party project owners and the remote possibility of not obtaining the legal title upon grid connection, the Company accounts for these projects as owned and record the costs incurred under Project Assets on the condensed consolidated balance sheet. Based on the Company’s intention to sell or hold for own use, the projects costs incurred for these EPC contracts are presented as operating activities or investing activities respectively in the condensed consolidated statement of cash flows.

As of September 30, 2015, the Company had respectively entered with these projects owners either a memorandum of understanding or pre-acquisition agreement to confirm the future transfer of the title and ownership upon the completion of construction and grid connection of the related PV systems.

Accounts Receivable

7. Accounts receivable

Accounts receivable, current and non-current, mainly represents amounts due from customers for 1) sales of Solar PV projects; 2) rendering of EPC services; 3) supply of electricity under power supply agreements (“PPA”); and 4) sales of solar PV related components.

The balance of allowance for doubtful accounts was $5,586 and $766 as of September 30, 2015 and December 31, 2014, respectively. There was write-off for bad debts of $23 and recovery of previously written off of nil for the nine-month and three-month periods ended September 30, 2015, respectively.

The allowance for doubtful accounts is provided against gross accounts receivable balances based on the Company’s best estimate of the amount of probable credit losses in the Company’s accounts receivable. The Company grants credit terms to credit-worthy customers. Terms vary per contract terms and range from 30 to 365 days. Contractually, the Company may charge interest for extended payment terms and require collateral. The Company regularly monitors and assesses the risk of not collecting amounts owed by customers. This evaluation is based upon a variety of factors, including an analysis of amounts current and past due along with relevant history and facts particular to the customer. The Company does not have any off-balance-sheet credit exposure related to its customers.

Included in the receivable balances arising from EPC services as at September 30, 2015 and December 31, 2014 was an amount of $13,214 and $6,794 respectively due from a customer in the PRC, Xinyu Realforce Energy Co., Ltd (“Realforce”). In the second half of 2014, the Group entered into an EPC contract with Realforce to construct a 21MW rooftop PV station. The construction of the PV station had been completed prior to December 31, 2014. In April 2015, Realforce entered into a sales and leaseback arrangement with the Company for the purpose of settling part of the outstanding receivable arising from the EPC contract. At that time, the outstanding receivable balances due from Realforce amounted to $24,840. Pursuant to the sales and leaseback arrangement, Realforce sold the Company certain solar PV components installed in the 21MW rooftop PV station at their fair value of $11,292 and immediately leased them back over a 10-year period with annual interest rate of 10% per annum under a finance lease contract. As a result of the above arrangement, the Company reduced the receivable balance due from Realforce by the fair value of the solar PV components of $11,292 and recognized a finance lease receivable of $11,292 due from Realforce. No gain or loss was recognized in the condensed consolidated statement of operation in relation to the above settlement through sales and leaseback arrangement. For the remaining $13,545 accounts receivable balances due from Realforce, the Company and Realforce have not reached any settlement arrangement up to the date of issuance of the financial statements. As at September 30, 2015, 100% equity interests in Realforce were pledged to the Company to secure its repayment obligations under the finance lease contract and the outstanding accounts receivable balances.

Stock-based Compensation

19. Stock-based Compensation

The Company measures stock-based compensation expense for all stock-based compensation awards based on the grant-date fair value and recognizes the cost in the financial statements over the employee requisite service period.

The following table summarizes the stock-based compensation expense, by type of awards for the periods as follow (in thousands):

	For the Three Months Ended					For the Nine Months Ended
	September 30, 2015		September 30, 2014			September 30, 2015		September 30, 2014
Employee stock options	$	1,255	$	(169	)	$	4,249	$	208

Total stock-based compensation expense	$	1,438	$	(169	)	$	35,748	$	208

The following table summarizes the stock-based compensation by line item for the periods as follow (in thousands):

	For the Three Months Ended					For the Nine Months Ended
	September 30, 2015		September 30, 2014			September 30, 2015		September 30, 2014

Tax effect on stock-based compensation expense		—		—			—		—
Total stock-based compensation expense after income taxes	$	1,438	$	(169	)	$	35,748	$	208

Stock-based compensation expense recognized in the Condensed Consolidated Statements of Operations is based on awards ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Determining Fair Value

Valuation and Amortization Method — The Company estimates the fair value of service-based and performance-based stock options granted using the Black-Scholes option-pricing formula. The fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. In the case of performance-based stock options, amortization does not begin until it is determined that meeting the performance criteria is probable. Service-based and performance-based options typically have a five to ten year life from date of grant and vesting periods of three to four years.

Expected Term — The Company’s expected term represents the period that the Company’s stock-based awards are expected to be outstanding. For awards granted subject only to service vesting requirements, the Company utilizes the simplified method for estimating the expected term of the stock-based award, instead of historical exercise data. For its performance-based awards, the Company has determined the expected term life to be five years based on contractual life and the seniority of the recipient.

Expected Volatility — The Company uses historical volatility of the price of its common shares to calculate the volatility for its granted options.

Expected Dividend — The Company has never paid dividends on its common shares and currently does not intend to do so, and accordingly, the dividend yield percentage is zero for all periods.

Risk-Free Interest Rate — The Company bases the risk-free interest rate used in the Black-Scholes valuation model upon the implied yield curve currently available on U.S. Treasury zero-coupon issues with a remaining term equal to the expected term used as the assumption in the model.

Assumptions used in the determination of the fair value of share-based payment awards using the Black-Scholes model for stock option grants during the three-month and nine-month periods ended September 30, 2015 and 2014 were as follows:

	For the Three Months Ended		For the Nine Months Ended
	September 30, 2015	September 30, 2014	September 30, 2015	September 30, 2014
Expected term	4	4	4	4
Risk-free interest rate	1.49% - 1.72%	1.25%	1.32% - 2.24%	1.25%
Expected volatility	139% - 141%	1.26%	139% - 142%	95%
Expected dividend yield	0%	0%	0%	0%

Equity Incentive Plan

On November 15, 2006, subject to approval of the stockholders, the Company adopted the 2006 Equity Incentive Plan (the “Plan”) which permits the Company to grant stock options to directors, officers or employees of the Company or others to purchase shares of common stock of the Company through awards of incentive and nonqualified stock options (“Option”), stock (“Restricted Stock” or “Unrestricted Stock”) and stock appreciation rights (“SARs”). The Plan was approved by the stockholders on February 7, 2007.

The Company has granted time-based share options and restricted stock under the Plan to directors, officers, employees and individual consultants of the Company. The time-based options generally vest 25% annually and expire five to ten years from the date of grant. Total number of shares reserved and available for grant and issuance pursuant to this Plan is equal to 9% of the number of outstanding shares of the Company. Shares issued under the Plan will be drawn from authorized and unissued shares or shares now held or subsequently acquired by the Company. Outstanding shares of the Company shall, for purposes of such calculation, include the number of shares of stock into which other securities or instruments issued by the Company are currently convertible (e.g., convertible preferred stock, convertible debentures, or warrants for Common Stock), but not outstanding options to acquire stock. At September 30, 2015 there was no share available for grant under the plan (9% of the outstanding shares of 676,867,538 less options and restricted stock outstanding and exercised since inception).

The exercise price of any Option will be determined by the Company when the Option is granted and may not be less than 100% of the fair market value of the shares on the date of grant, and the exercise price of any incentive stock option granted to a stockholder with a 10% or greater shareholding will not be less than 110% of the fair market value of the shares on the date of grant. The exercise price per share of a SAR will be determined by the Company at the time of grant, but will in no event be less than the fair market value of a share of Company’s stock on the date of grant.

On January 12, 2015, February 13, 2015, and June 29, 2015, the Board of Directors approved the grants of restricted stock unit awards (“RSU”) to core management members, other management and staff, pursuant to the terms of the 2006 Equity Incentive Plan. The total number of RSUs granted is 20,468,400 shares. Among these, the vesting schedules for the chairman, deputy chairman and CFO (“core management”) are 100% vested at the grant date and the vesting schedules for the rest RSUs granted to other management and staff would be vested within the next four years equally. The Company used the market price of its share at grant date as the fair value of the RSUs in calculating the stock based compensation expense. The core management exercised all RSUs of 19,200,000 and all these shares were issued to them in March 2015 (See Note 18 — Stockholders’ Equity).

Sales-leaseback, lease description			In April 2015, Realforce entered into a sales and leaseback arrangement with the Company for the purpose of settling part of the outstanding receivable arising from the EPC contract. At that time, the outstanding receivable balances due from Realforce amounted to $24,840. Pursuant to the sales and leaseback arrangement, Realforce sold the Company certain solar PV components installed in the 21MW rooftop PV station at their fair value of $11,292 and immediately leased them back over a 10-year period with annual interest rate of 10% per annum under a finance lease contract. As a result of the above arrangement, the Company reduced the receivable balance due from Realforce by the fair value of the solar PV components of $11,292 and recognized a finance lease receivable of $11,292 due from Realforce. No gain or loss was recognized in the condensed consolidated statement of operation in relation to the above settlement through sales and leaseback arrangement. For the remaining $13,545 accounts receivable balances due from Realforce, the Company and Realforce have not reached any settlement arrangement up to the date of issuance of the financial statements. As at September 30, 2015, 100% equity interests in Realforce were pledged to the Company to secure its repayment obligations under the finance lease contract and the outstanding accounts receivable balances.

Recently Issued Accounting Pronouncements

3. Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), to clarify the principles of recognizing revenue and create common revenue recognition guidance between U.S. GAAP and International Financial Reporting Standards. An entity has the option to apply the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this standard recognized at the date of initial application. ASU 2014-09 is effective for fiscal years and interim periods within those years beginning after December 15, 2017, and early adoption is permitted for periods beginning after December 15, 2016. The Company has not determined which transition method it will adopt, and is currently evaluating the impact of this standard on its consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements — Going Concern (Subtopic 205- 40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which requires management to evaluate, at each annual and interim reporting period, whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued and to provide related disclosures. ASU 2014-15 is effective for the Company for the fiscal year ending December 31, 2016 and for interim periods thereafter. The Company is currently evaluating the impact of this standard on its consolidated financial statements.

In January 2015, the FASB issued ASU No. 2015-01, Income Statement — Extraordinary and Unusual Items (Subtopic 225- 20), which eliminates the concept of reporting for extraordinary items. ASU 2015-01 is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning on January 1, 2016. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

On February 18, 2015, the FASB issued ASU No. 2015-02, Consolidation, which reduces the number of consolidation models and simplifies the current standard. Entities may no longer need to consolidate a legal entity in certain circumstances based solely on its fee arrangements when certain criteria are met. ASU 2015-02 reduces the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity. ASU 2015-02 is effective for the Company’s fiscal year ending December 31, 2016. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, Interest — Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 is effective for the Company on a retrospective basis on January 1, 2016. Early adoption is permitted, but only for debt issuance costs that have not been reported in financial statements previously issued or available for issuance. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. ASU 2015-11 applies to inventory that is measured using the first-in, first-out (“FIFO”) or average cost method and requires measurement of that inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

Income Tax Disclosure [Abstract]

Income Taxes

20. Income Taxes

The Company calculates its interim income tax provision in accordance with ASC 740-270 Income Taxes. At the end of each interim period, the Company estimates the annual effective tax rate and applies that rate to its ordinary quarterly earnings. The tax expense or benefit related to significant, unusual, or extraordinary items that will be separately reported or reported net of their related tax effect, is recognized in the interim period in which those items occur. The Company evaluates its ability to recover deferred tax assets, in full or in part, by considering all available positive and negative evidence, including past operating results and our forecast of future taxable income on a jurisdictional basis. The Company bases its estimate of current and deferred taxes on the tax laws and rates that are currently in effect in the appropriate jurisdiction. Changes in laws or rates may affect the tax provision as well as the amount of deferred tax assets or liabilities.

The effective income tax rate of the Company for the nine-month period ended September 30, 2015 and 2014 was (0.6)% and (9.9)%, respectively, and the three-month period ended September 30, 2015 and 2014 was 2.5% and (12.9)%, respectively. For both 2015 and 2014, the Company expects to generate taxable income in certain jurisdictions while still experiencing an overall worldwide loss.

The Company has not provided for deferred taxes relating to the undistributed earnings of its foreign subsidiaries (primarily the subsidiaries in the People’s Republic of China) amounted to $2.4 million and $8.8 million as of September 30, 2015 and December 31, 2014, respectively, which are expected to be permanently reinvested.

The Company and its subsidiaries did not have any unrecognized tax benefits or liabilities as of September 30, 2015 and December 31, 2014. The Company does not anticipate that its unrecognized tax benefits or liability position will change significantly over the next twelve months.

Fair Value Disclosures [Abstract]

Fair Value Measurement

13. Fair value measurement

In arriving at fair-value estimates of the call option as discussed in Note 4- Business Combination, the Company utilizes the most observable inputs available for the valuation technique employed. If a fair-value measurement reflects inputs at multiple levels within the fair value hierarchy, the fair-value measurement is characterized based upon the lowest level input. For the Company, recurring fair-value measurements are performed for the derivative assets. The Company does not have any derivative asset that reduce risk associated with hedging exposure and has not designated the derivative asset as a hedge instrument.

The Company did not have any derivatives valued using Level 1 and Level 2 inputs as of September 30, 2015 and December 31, 2014. The derivative asset relating to the call option was classified in Level 3 of the fair value hierarchy in which management has used at least one significant unobservable input in the valuation model. The fair value of the derivative asset was $420 and $424 at the grant date of May 28, 2015 and September 30, 2015 respectively, which were recorded as other financial assets in the Consolidated Balance Sheet as of September 30, 2015. Gain arising from change in fair value of $4 and nil was recorded as Other income-others in the consolidated statement of operations for the nine-month and three-month periods ended September 30, 2015 respectively. The Company determines the fair value using binomial model with significant input on the fair value of the remaining 20% equity interest of Solar Juice and volatility unobservable in the market. The volatility is determined by the average standard derivation of the comparable companies applicable over a time period corresponding to the remaining life of the call option. Significant increases or decreases in this unobservable input would result in a significantly lower or higher fair value measurement.

The derivative asset relating to the Warrant to acquire ENS’s common stock was classified in Level 3 of the fair value hierarchy in which management has used at least one significant unobservable input in the valuation model. The fair value of the derivative asset was $6,154 on September 30, 2015, which were recorded as Derivative asset in the Consolidated Balance Sheet as of September 30, 2015. Gain arising from change in fair value of $10,793 was recorded as Other income-Change in market value of derivative asset/liability in the consolidated statement of operations for the nine-month and three-month periods ended September 30, 2015 respectively. The Company determines the fair value of the Warrant using binomial model with significant inputs on the vesting schedule and volatility unobservable in the market. The vesting schedule of the Warrant is estimated by the Management based on expected timetable to fulfill the vesting condition. The volatility is determined by the average standard derivation of the comparable companies applicable over a period with length commensurate to the time to maturity of the Warrant as of the Valuation Date. Significant variance of the above-mentioned inputs would result in a significantly lower or higher fair value measurement.

The Convertible Preferred Stock of ENS was classified in Level 3 of the fair value hierarchy in which management has used at least one significant unobservable input in the valuation model. The fair value of the Convertible Preferred Stock of ENS is determined by the fair value of the total common stock with a discount for Lack of Marketability Discount (“LOMD”). The LOMD as of the Valuation Date is derived by reference to put option based on Black-Scholes Option Pricing Model, with significant inputs on the volatility and expected terms of each tranche of the Preferred Stock unobservable in the market. The volatility is determined by the average standard derivation of the comparable companies applicable over a period with length commensurate to the expected term of the Convertible Preferred Stock, and the expected term of each tranche of the Convertibel Preferred Stock is based on Management’s estimation of the conversion schedule. Significant variance of the above-mentioned inputs would result in a significantly lower or higher fair value measurement.

There have been no transfers between Level 1, Level 2, or Level 3 categories.

There were no assets or liabilities measured on a non-recurring basis as of September 30, 2015 and December 31, 2014. For financial instruments that are not required to be measured at fair value, the following method and assumptions were used to estimate the fair value as at September 30, 2015 and December 31, 2014:

Cash and cash equivalents, restricted cash, accounts receivable and payable, short term investments, bank deposits with maturity over three months, finance lease receivables, current, accrued liabilities, advance from customers and other current liabilities — costs approximates fair value because of the short maturity period.

Notes receivable, current, and notes receivable, noncurrent — The fair value of Notes receivable, current were based on anticipated cash flows, which approximates carrying value, and were classified in Level 2 of the fair value hierarchy. The fair value of Notes receivable, noncurrent were classified in Level 3 of the fair value hierarchy. The Company used multiple techniques, including an income approach applying discounted cash flows approach, to measure the fair value using Level 3 inputs; the results of each technique have been reasonably weighted based upon management’s judgment applying qualitative considerations to determine the fair value at the measurement date. The fair value of notes receivable is determined to approximate its carrying value.

Convertible bonds. The estimated fair value was $52,968 and $39,423 as of September 30, 2015 and December 31, 2014. The fair value of convertible bonds was classified in Level 2 of the fair value hierarchy. The Company determines the fair value using binomial model with significant input on prices and votes observable in the market.

Short term borrowings. The carrying amount approximates fair value due to the short maturity and their variable market rates of interest that change with current Prime and no change in counterparty credit risk and were classified as Level 2 of the fair value hierarchy.

Finance lease receivables, noncurrent, and other noncurrent liabilities. The Company used discounted cash flow approach to determine the fair value, which was classified in Level 3 of the fair value hierarchy. The fair value of finance lease receivables, noncurrent, and other noncurrent liabilities is determined to approximate its carrying value.
