Summary of Significant Accounting Policies (Policies)	6 Months Ended
Jun. 30, 2022
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of presentation and principles of consolidation The accompanying unaudited condensed consolidated financial statements include the results of the Company and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements and pursuant to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments have been made that are considered necessary for a fair statement of our financial position as of June 30, 2022, and December 31, 2021, our results of operations for the three and six months ended June 30, 2022 and 2021, and our cash flows for the six months ended June 30, 2022 and 2021. The condensed consolidated balance sheet as of December 31, 2021 has been derived from the Company’s audited consolidated financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. Operating results for the three and six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. Intercompany balances and transactions have been eliminated in consolidation. Certain information and disclosures normally included in the notes to annual financial statements prepared in accordance with GAAP have been omitted from these interim financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, as updated in our Current Report on Form 8-K filed June 13, 2022. On April 28, 2021, we effected an approximately 8.25-for-1 forward split of our issued and outstanding shares of common stock, par value $0.0001 per share. As a result of the forward stock split, one (1) share of common stock issued and outstanding was automatically increased to approximately 8.25 shares of issued and outstanding common stock, without any change in the par value per share. All information related to common stock, stock options, restricted stock awards and earnings per share have been retroactively adjusted to give effect to the forward stock split for all periods presented, unless otherwise indicated. We currently operate in one business segment, the manufacturing and servicing of solar tracker systems
Liquidity	Liquidity We have incurred cumulative losses since inception, resulting in an accumulated deficit of $202.7 million at June 30, 2022, and have a history of cash outflows from operations. During the year ended December 31, 2021, and the six months ended June 30, 2022, we had $132.9 million and $36.4 million, respectively, of cash outflow from operations. At June 30, 2022, we had $66.0 million of cash on hand, $90.5 million of working capital and approximately $98.1 million of unused borrowing capacity under our existing revolving credit facility. The revolving credit facility includes a financial condition covenant stating we are required to have a minimum liquidity, consisting of cash on hand and unused borrowing capacity, of $50.0 million as of each quarter end through March 31, 2023. After considering this financial condition covenant, we had approximately $114.1 million of available liquidity as of June 30, 2022, in order to retain access to our revolving credit facility. Additionally, we had no long-term borrowings or other material obligations requiring the use of cash as of June 30, 2022. On March 25, 2022, the U.S. Department of Commerce, in response to a petition by Auxin Solar, Inc., initiated an investigation of claims related to alleged circumvention of U.S. antidumping and countervailing duties ("AD/CVD") by solar manufacturers in certain Southeast Asian countries in an effort to determine whether or not solar cells and/or modules made in those Southeast Asian nations use parts originating from China in order to circumvent the AD/CVD tariffs. This decision resulted in some developers deferring projects later in the year due to the uncertainty of panel supply and costs, which has negatively impacted our current period revenues and cash flows and is expected to continue to negatively impact our anticipated revenues and our cash flows for some portion of the remainder of the year. On June 6, 2022, it was announced pursuant to the U.S. Defense Production Act, that President Biden had issued an executive order to allow U.S. solar deployers the ability to import solar modules and cells from Cambodia, Malaysia, Thailand and Vietnam free from certain duties for 24 months, along with other actions taken to accelerate U.S. domestic production of clean energy technologies. U.S. developers are now looking to reactivate projects they were pushing out and we expect this will increase demand for solar trackers in the U.S. in 2023. Our costs are affected by certain component costs including steel, motors and micro-chips, as well as transportation costs. Current market conditions that constrain supply of materials and disrupt the flow of materials from international vendors impact the cost of our products and services. These cost increases impact our operating margins. We have taken steps to expand and diversify our manufacturing partnerships and have employed alternative modes of transportation to mitigate the impact of the current headwinds in the global supply chain and logistics markets. Although overall transportation costs are higher than one year ago, there has been a decline in recent months in costs for both charter vessels and in the premium container market, as well as an easing of congestion in U.S. ports. However, recent COVID shutdowns in China have created a backlog of exports and increased demand for container shipments from China. We continue to monitor the logistics markets and will adjust our use of various modes of transportation if and when warranted to optimize our transportation costs. Additionally, in February 2022, we contracted with a related-party consulting firm to support us with ongoing improvements to our processes and performance in various areas including design, sourcing, logistics, pricing, software and standard configuration. For further information regarding this consulting firm, see "Note 14. Related party transactions". In accordance with ASC 205-40, Going Concern, we have evaluated whether there are conditions and events, considered in the aggregate, which raise substantial doubt about our ability to continue as a going concern within one year after the date these condensed consolidated financial statements are issued. During the second quarter of 2022, the Biden Administration announced a two-year moratorium on duties from importing solar modules and cells from certain countries as described above, which we believe has reduced the level of uncertainty among solar project owners and developers with regard to new project development. We also took significant actions to address the current market challenges through the following: • certain members of our senior management team have foregone certain cash compensation in exchange for equity compensation; • we have frozen non-essential hiring, reduced our travel expenses, and have decreased the future use of consultants and are deferring non-critical initiatives; • we have emphasized cash collections from customers during Q2, and continue to negotiate improved payment terms with both our customers and vendors; • we have initiated frequent, consistent communication with our customers, which has allowed us to resolve issues preventing timely collection of certain past due outstanding receivables; and • we continue to explore options to obtain additional sources of capital through either the issuance of new debt or equity. For example, we executed Amendment No. 2 to our existing revolving credit facility in June 2022, as described further in Note 10 below, which has increased available liquidity under our credit facility through March 31, 2023. Management believes that our existing capital, which includes cash on hand, as well as our unused borrowing capacity under our revolving credit facility is sufficient for us to fund our operations for at least one year from the date of issuance of these consolidated financial statements. Accordingly, the accompanying financial statements assume we will continue as a going concern through the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business. While we have achieved success in executing certain of the initiatives above, we continue to work to further reduce our use of cash to fund our operations. We expect the two-year moratorium on duties announced by President Biden in June 2022 to reduce the level of uncertainty in the market due to the ongoing AD/CVD investigation by the U.S. Department of Commerce, as described above. At the same time, however, the Uyghur Forced Labor Prevention Act, or UFLPA, became effective in June 2022, resulting in new rules for module importers and reviews by U.S. Customs and Border Patrol. There is still uncertainty in the market around achieving full compliance with UFLPA, whether related to sufficient traceability of materials or other factors. Once there is additional clarity around this, and customers get line-of-sight to module deliveries, we believe the market will see a swift and substantial recovery. One other potential change is the proposed "Inflation Reduction Act", which includes incentives and an extension of the investment tax credit. While there are already many underlying drivers of growth in the solar industry, we believe this bill would serve to further bolster and extend future demand. However, the expected positive impact on demand for our products may take longer than expected to occur. In addition, market conditions could deteriorate significantly from what we currently expect, and regulatory and international trade policies could become more stringent as a result of (i) findings from the Department of Commerce's AD/CVD investigation, (ii) the level of enforcement of regulations issued under UFLPA, and (iii) other factors, which may result in a need for us to issue additional debt or obtain new equity financing to fund our operations beyond the next twelve months. We may be unable to obtain any desired additional financing on terms favorable to us, or at all, depending on market and other conditions. The ability to raise additional financing depends on numerous factors that are outside of our control, including macroeconomic factors such as the impact of the COVID 19 pandemic, inflation and the ongoing conflict in the Ukraine, market conditions, the health of financial institutions, investors' and lenders' assessments of our prospects and the prospects of the solar industry in general.
Cash and cash equivalents	Cash and cash equivalents We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. We regularly maintain cash balances that exceed federally insured amounts, but we have experienced no losses associated with these amounts to date.
Accounts receivable, net	Accounts receivable, net Trade receivables are recorded at invoiced amounts, net of allowances for doubtful accounts, if applicable, and do not bear interest. We generally do not require collateral from our customers; however, in certain circumstances, we may require letters of credit, other collateral, additional guarantees or advance payments. The allowance for doubtful accounts is based on our assessment of the collectability of our customer accounts. We regularly review our accounts receivable that remain outstanding past their applicable payment terms and establish allowances or make potential write-offs by considering certain factors such as historical experience, industry data, credit quality, age of balances and current economic conditions that may affect a customers’ ability to pay. Receivables arising from revenue recognized in excess of billings represents our unconditional right to consideration before customers are invoiced due to the level of progress obtained as of period end on our contracts to install tracker systems and related equipment. Further information may be found below in our revenue recognition policy.
Inventory, net	Inventories, net Inventories are stated at the lower of cost or net realizable value, with costs computed on a first-in, first-out basis. The Company periodically reviews its inventories for excess and obsolete items and adjusts carrying costs to estimated net realizable values when they are determined to be less than cost. Goodwill We recognize goodwill as the excess of the purchase price over the estimated fair value of the identified assets and liabilities acquired in a business combination accounted for using the acquisition method. Goodwill is not amortized but is subject to a periodic assessment for impairment at least annually, or whenever events and circumstances indicate an impairment may exist.
Use of Estimates	Use of estimates Preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported revenue and expenses during the period. Estimates are used for calculating the measure of progress of our solar tracker projects and deriving the standalone selling prices of the individual performance obligations when determining amounts to recognize for revenue, estimating allowances for doubtful accounts and slow-moving and obsolete inventory, determining useful lives of noncurrent assets and the estimated fair value of those assets for impairment assessments, and estimating the fair value of investments, stock compensation awards, warranty liabilities and federal and state taxes and contingencies. We base our estimates on historical experience and anticipated results, trends, and various other assumptions that we believe are reasonable under the circumstances, including assumptions as to future events. Actual results could differ from those estimates.
Concentration of Credit Risk	Concentration of credit risk Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and accounts receivable. We regularly maintain cash balances with various financial institutions that exceed federally insured amounts, but we have experienced no losses associated with these amounts to date. The Company extends credit to customers in the normal course of business, often without requiring collateral. The Company performs credit analyses and monitors the financial health of its customers to reduce credit risk. The Company’s accounts receivables are derived from revenue earned from customers primarily located in the U.S., Australia and in the Asia Pacific region. No countries other than the U.S. and Australia account for 10% or more of our revenue. Most of our customers are project developers, solar asset owners and engineering, procurement and construction (“EPC”) contractors that design and build solar energy projects. Often times, a small number of customers account for a significant portion of our outstanding receivables at period end and our total revenue for the year.
Stock-Based Compensation	Stock-based compensation We recognize compensation expense for all share-based payment awards made, including stock options and restricted stock, based on the estimated fair value of the award on the grant date, in the accompanying condensed consolidated statements of comprehensive loss. We calculate the fair value of stock options using the Black-Scholes Option-Pricing model for awards with service-based vesting or through use of a lattice model or a Monte Carlo simulation for awards with market conditions. The fair value of restricted stock grants is based on the estimated fair value of the Company's common stock on the date of grant. Since completion of our IPO, we consider the closing price of our stock, as reported on the Nasdaq Global Market, to be the fair value of our stock on the grant date. Forfeitures are accounted for as they occur. For service-based awards, stock-based compensation is recognized using the straight-line attribution approach over the requisite service period. For performance-based awards, stock-based compensation is recognized based on graded vesting over the requisite service period when the performance condition is probable of being achieved.
Revenue Recognition	Revenue recognition Product revenue includes revenue from the sale of solar tracker systems and customized components of those systems, individual part sales for certain specific transactions, and sale of term-based software licenses. Term-based software licenses are deployed on the customers’ own servers and have significant standalone functionality. Service revenue includes revenue from shipping and handling services, subscription fees from licensing subscription services, and maintenance and support services in connection with the term-based software licenses. Our subscription-based enterprise licensing model typically has contract terms ranging from one to two years and consists of subscription fees from the licensing of subscription services. Our hosted on-demand service arrangements do not provide customers with the right to take possession of the software supporting the hosted services. Support services include ongoing security updates, upgrades, bug fixes, and maintenance. We recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services by following a five-step process, (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when or as the Company satisfies a performance obligation, as further described below. Identify the contract with a customer: A contract with a customer exists when (i) the Company enters into an enforceable contract with a customer that defines each party’s rights regarding the products and services to be transferred and identifies the payment terms related to these products and services, (ii) the contract has commercial substance and, (iii) the Company determines that collection of substantially all consideration for products and services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. In assessing the recognition of revenue, we also evaluate whether two or more contracts should be combined and accounted for as one contract and if the combined or single contract should be accounted for as multiple performance obligations which could change the amount of revenue and profit (loss) recorded in a period. Change orders may include changes in specifications or design, manner of performance, equipment, materials, scope of work, and/or the period of completion of the project. We analyze change orders to determine if they should be accounted for as a modification to an existing contract or a new stand-alone contract. Contracts we enter into with our customers for sale of solar tracker systems are generally under two different types of arrangements: (1) purchase agreements and equipment supply contracts (“Purchase Agreements”) and (2) sale of individual parts for those systems. Change orders from our customers are generally modifications to existing contracts and are included in the total estimated contract revenue when it is probable that the change order will result in additional value that can be reliably estimated and realized. Identify the performance obligations in the contract: We enter into contracts that can include various combinations of products and services, which are either capable of being distinct and accounted for as separate performance obligations or as one performance obligation since the majority of tasks and services are part of a single project or capability. However, determining whether products or services are considered distinct performance obligations that should be accounted for separately versus together may sometimes require significant judgment. Our Purchase Agreements typically include two performance obligations- 1) our solar tracker systems or customized components of those systems, and 2) shipping and handling services. The deliverables included as part of our solar tracker systems are predominantly accounted for as one performance obligation, as these deliverables are part of a combined promise to deliver a project. The revenue for shipping and handling services will be recognized over time based on progress in meeting shipping terms of the arrangements, as this faithfully depicts the Company’s performance in transferring control. Sale of individual parts of our solar tracker systems for certain specific transactions includes multiple performance obligations consisting of individual parts of those systems. Revenue is recognized for parts sales at a point in time when the obligations under the terms of the contract with our customer are satisfied. Generally, this occurs with the transfer of control of the asset, which is in line with shipping terms. Determine the transaction price: The transaction price is determined based on the consideration to which we will be entitled in exchange for transferring services to the customer. Such amounts are typically stated in the customer contract, and to the extent that we identify variable consideration, we will estimate the variable consideration at the onset of the arrangement as long as it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The majority of our contracts do not contain variable consideration provisions as a continuation of the original contract. None of our contracts contain a significant financing component. Taxes collected from customers and remitted to governmental authorities are not included in revenue. Allocate the transaction price to performance obligations in the contract: Once we have determined the transaction price, we allocate the total transaction price to each performance obligation in a manner depicting the amount of consideration to which we expect to be entitled in exchange for transferring the good(s) or service(s) to the customer. We allocate the transaction price to each performance obligation identified in the contract on a relative standalone selling price basis. We use the expected cost-plus margin approach based on hardware, labor, and related overhead cost to estimate the standalone selling price of our solar tracker systems, customized components of those systems, and individual parts for certain specific transactions. We use the adjusted market assessment approach for all other performance obligations except shipping, handling, and logistics. For shipping, handling, and logistics performance obligations, we use a residual approach to calculate the standalone selling price, because of the nature of the highly variable and broad range of prices we charge to various customers for this performance obligation in the contracts. Recognize revenue when or as the Company satisfies a performance obligation: For each performance obligation identified, we determine at contract inception whether we satisfy the performance obligation over time or at a point in time. The performance obligations in the contracts for our solar tracker systems and customized components of those systems are satisfied over-time as work progresses, utilizing an input measure of progress determined by cost-to-cost measures on these projects as this faithfully depicts our performance in transferring control. Additionally, our performance does not create an asset with an alternative use, due to the highly customized nature of the product, and we have an enforceable right to payment for performance completed to date. Our performance obligations for individual part sales for certain specific transactions are recognized point-in-time as and when control transfers based on the Incoterms for the contract. Our performance obligations for term-based software licenses are recognized point-in-time as and when control transfers, either upon delivery to the customer or the software license start date, whichever is later. Our performance obligation for shipping and handling services is satisfied over-time as the services are delivered over the term of the contract. We recognize subscription services sales/other services on a straight-line basis over the contract period. With regard to support revenue, a time-elapsed method is used to measure progress because we transfer control evenly over the contractual period. Accordingly, the fixed consideration related to support revenue is generally recognized on a straight-line basis over the contract term. Contract assets and liabilities: The timing of revenue recognition, billing, and cash collection results in the recognition of accounts receivable, unbilled receivables for revenue recognized in excess of billings, and deferred revenue in the Condensed Consolidated Balance Sheets. We may receive advances or deposits from our customers before revenue is recognized, resulting in contract liabilities, which are reflected as “deferred revenue” on our Condensed Consolidated Balance Sheets. Cost of revenue consists primarily of costs related to raw materials, freight and delivery, product warranty, and personnel costs (salaries, bonuses, benefits, and stock-based compensation). Personnel costs in cost of revenue include both direct labor costs as well as costs attributable to any individuals whose activities relate to the procurement, installment, and delivery of the finished product and services. Personnel costs during 2021 are reported net of federal employee retention credits received. Deferred cost of revenue results from the timing differences between the costs incurred in advance of the satisfaction of all revenue recognition criteria consistent with our revenue recognition policy.
Warranty	Warranty Typically, the sale of solar tracker projects includes parts warranties to customers as part of the overall price of the product. We provide standard assurance type warranties for our products for periods generally ranging from two to ten years. We record a provision for estimated warranty expenses in cost of sales, net of amounts recoverable from manufacturers under their warranty obligations to us. We do not maintain general or unspecified reserves; all warranty reserves are related to specific projects. All actual or estimated material costs incurred for warranty services in subsequent periods are charged to those established reserves. While we periodically monitor our warranty activities and claims, if actual costs incurred were to be different from our estimates, we would recognize adjustments to our warranty reserves in the period in which those differences arise or are identified.
Recent Accounting Pronouncements	Recent accounting pronouncements adopted and not yet adopted Adopted We adopted Accounting Standards Update ("ASU") 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contract in an Entity's Own Equity, effective January 1, 2022. This standard had no impact on our financial position or results operations at the time of adoption. Not yet adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 changes the impairment model for most financial assets and requires the use of an expected loss model in place of the currently used incurred loss method. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. The update to the standard is effective for the Company for its fiscal year beginning after December 15, 2022, to the extent the Company remains an emerging growth company, and early adoption is permitted. We do not expect the adoption of ASU 2016-13 to have a material impact on our consolidated financial statements.

Basis of Presentation and Principles of Consolidation

Basis of presentation and principles of consolidation

The accompanying unaudited condensed consolidated financial statements include the results of the Company and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements and pursuant to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments have been made that are considered necessary for a fair statement of our financial position as of June 30, 2022, and December 31, 2021, our results of operations for the three and six months ended June 30, 2022 and 2021, and our cash flows for the six months ended June 30, 2022 and 2021. The condensed consolidated balance sheet as of December 31, 2021 has been derived from the Company’s audited consolidated financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. Operating results for the three and six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. Intercompany balances and transactions have been eliminated in consolidation.

Certain information and disclosures normally included in the notes to annual financial statements prepared in accordance with GAAP have been omitted from these interim financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, as updated in our Current Report on Form 8-K filed June 13, 2022.

On April 28, 2021, we effected an approximately 8.25-for-1 forward split of our issued and outstanding shares of common stock, par value $0.0001 per share. As a result of the forward stock split, one (1) share of common stock issued and outstanding was automatically increased to approximately 8.25 shares of issued and outstanding common stock, without any change in the par value per share. All

information related to common stock, stock options, restricted stock awards and earnings per share have been retroactively adjusted to give effect to the forward stock split for all periods presented, unless otherwise indicated.

We currently operate in one business segment, the manufacturing and servicing of solar tracker systems

Liquidity

We have incurred cumulative losses since inception, resulting in an accumulated deficit of $202.7 million at June 30, 2022, and have a history of cash outflows from operations. During the year ended December 31, 2021, and the six months ended June 30, 2022, we had $132.9 million and $36.4 million, respectively, of cash outflow from operations. At June 30, 2022, we had $66.0 million of cash on hand, $90.5 million of working capital and approximately $98.1 million of unused borrowing capacity under our existing revolving credit facility. The revolving credit facility includes a financial condition covenant stating we are required to have a minimum liquidity, consisting of cash on hand and unused borrowing capacity, of $50.0 million as of each quarter end through March 31, 2023. After considering this financial condition covenant, we had approximately $114.1 million of available liquidity as of June 30, 2022, in order to retain access to our revolving credit facility. Additionally, we had no long-term borrowings or other material obligations requiring the use of cash as of June 30, 2022.

On March 25, 2022, the U.S. Department of Commerce, in response to a petition by Auxin Solar, Inc., initiated an investigation of claims related to alleged circumvention of U.S. antidumping and countervailing duties ("AD/CVD") by solar manufacturers in certain Southeast Asian countries in an effort to determine whether or not solar cells and/or modules made in those Southeast Asian nations use parts originating from China in order to circumvent the AD/CVD tariffs. This decision resulted in some developers deferring projects later in the year due to the uncertainty of panel supply and costs, which has negatively impacted our current period revenues and cash flows and is expected to continue to negatively impact our anticipated revenues and our cash flows for some portion of the remainder of the year. On June 6, 2022, it was announced pursuant to the U.S. Defense Production Act, that President Biden had issued an executive order to allow U.S. solar deployers the ability to import solar modules and cells from Cambodia, Malaysia, Thailand and Vietnam free from certain duties for 24 months, along with other actions taken to accelerate U.S. domestic production of clean energy technologies. U.S. developers are now looking to reactivate projects they were pushing out and we expect this will increase demand for solar trackers in the U.S. in 2023.

Our costs are affected by certain component costs including steel, motors and micro-chips, as well as transportation costs. Current market conditions that constrain supply of materials and disrupt the flow of materials from international vendors impact the cost of our products and services. These cost increases impact our operating margins. We have taken steps to expand and diversify our manufacturing partnerships and have employed alternative modes of transportation to mitigate the impact of the current headwinds in the global supply chain and logistics markets. Although overall transportation costs are higher than one year ago, there has been a decline in recent months in costs for both charter vessels and in the premium container market, as well as an easing of congestion in U.S. ports. However, recent COVID shutdowns in China have created a backlog of exports and increased demand for container shipments from China. We continue to monitor the logistics markets and will adjust our use of various modes of transportation if and when warranted to optimize our transportation costs. Additionally, in February 2022, we contracted with a related-party consulting firm to support us with ongoing improvements to our processes and performance in various areas including design, sourcing, logistics, pricing, software and standard configuration. For further information regarding this consulting firm, see "Note 14. Related party transactions".

In accordance with ASC 205-40, Going Concern, we have evaluated whether there are conditions and events, considered in the aggregate, which raise substantial doubt about our ability to continue as a going concern within one year after the date these condensed consolidated financial statements are issued. During the second quarter of 2022, the Biden Administration announced a two-year moratorium on duties from importing solar modules and cells from certain countries as described above, which we believe has reduced the level of uncertainty among solar project owners and developers with regard to new project development. We also took significant actions to address the current market challenges through the following:

•

certain members of our senior management team have foregone certain cash compensation in exchange for equity compensation;

•

we have frozen non-essential hiring, reduced our travel expenses, and have decreased the future use of consultants and are deferring non-critical initiatives;

•

we have emphasized cash collections from customers during Q2, and continue to negotiate improved payment terms with both our customers and vendors;

•

we have initiated frequent, consistent communication with our customers, which has allowed us to resolve issues preventing timely collection of certain past due outstanding receivables; and

•

we continue to explore options to obtain additional sources of capital through either the issuance of new debt or equity. For example, we executed Amendment No. 2 to our existing revolving credit facility in June 2022, as described further in Note 10 below, which has increased available liquidity under our credit facility through March 31, 2023.

Management believes that our existing capital, which includes cash on hand, as well as our unused borrowing capacity under our revolving credit facility is sufficient for us to fund our operations for at least one year from the date of issuance of these consolidated financial statements. Accordingly, the accompanying financial statements assume we will continue as a going concern through the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business.

While we have achieved success in executing certain of the initiatives above, we continue to work to further reduce our use of cash to fund our operations. We expect the two-year moratorium on duties announced by President Biden in June 2022 to reduce the level of uncertainty in the market due to the ongoing AD/CVD investigation by the U.S. Department of Commerce, as described above. At the same time, however, the Uyghur Forced Labor Prevention Act, or UFLPA, became effective in June 2022, resulting in new rules for module importers and reviews by U.S. Customs and Border Patrol. There is still uncertainty in the market around achieving full compliance with UFLPA, whether related to sufficient traceability of materials or other factors. Once there is additional clarity around this, and customers get line-of-sight to module deliveries, we believe the market will see a swift and substantial recovery. One other potential change is the proposed "Inflation Reduction Act", which includes incentives and an extension of the investment tax credit. While there are already many underlying drivers of growth in the solar industry, we believe this bill would serve to further bolster and extend future demand. However, the expected positive impact on demand for our products may take longer than expected to occur. In addition, market conditions could deteriorate significantly from what we currently expect, and regulatory and international trade policies could become more stringent as a result of (i) findings from the Department of Commerce's AD/CVD investigation, (ii) the level of enforcement of regulations issued under UFLPA, and (iii) other factors, which may result in a need for us to issue additional debt or obtain new equity financing to fund our operations beyond the next twelve months. We may be unable to obtain any desired additional financing on terms favorable to us, or at all, depending on market and other conditions. The ability to raise additional financing depends on numerous factors that are outside of our control, including macroeconomic factors such as the impact of the COVID 19 pandemic, inflation and the ongoing conflict in the Ukraine, market conditions, the health of financial institutions, investors' and lenders' assessments of our prospects and the prospects of the solar industry in general.

Cash and cash equivalents

We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. We regularly maintain cash balances that exceed federally insured amounts, but we have experienced no losses associated with these amounts to date.

Accounts receivable, net

Trade receivables are recorded at invoiced amounts, net of allowances for doubtful accounts, if applicable, and do not bear interest. We generally do not require collateral from our customers; however, in certain circumstances, we may require letters of credit, other collateral, additional guarantees or advance payments. The allowance for doubtful accounts is based on our assessment of the collectability of our customer accounts. We regularly review our accounts receivable that remain outstanding past their applicable payment terms and establish allowances or make potential write-offs by considering certain factors such as historical experience, industry data, credit quality, age of balances and current economic conditions that may affect a customers’ ability to pay.

Receivables arising from revenue recognized in excess of billings represents our unconditional right to consideration before customers are invoiced due to the level of progress obtained as of period end on our contracts to install tracker systems and related equipment. Further information may be found below in our revenue recognition policy.

Inventory, net

Inventories, net

Inventories are stated at the lower of cost or net realizable value, with costs computed on a first-in, first-out basis. The Company periodically reviews its inventories for excess and obsolete items and adjusts carrying costs to estimated net realizable values when they are determined to be less than cost.

Goodwill

We recognize goodwill as the excess of the purchase price over the estimated fair value of the identified assets and liabilities acquired in a business combination accounted for using the acquisition method. Goodwill is not amortized but is subject to a periodic assessment for impairment at least annually, or whenever events and circumstances indicate an impairment may exist.

Use of Estimates

Use of estimates

Preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported revenue and expenses during the period. Estimates are used for calculating the measure of progress of our solar tracker projects and deriving the standalone selling prices of the individual performance obligations when determining amounts to recognize for revenue, estimating allowances for doubtful accounts and slow-moving and obsolete inventory, determining useful lives of noncurrent assets and the estimated fair value of those assets for impairment assessments, and estimating the fair value of investments, stock compensation awards, warranty liabilities and federal and state taxes and contingencies. We base our estimates on historical experience and anticipated results, trends, and various other assumptions that we believe are reasonable under the circumstances, including assumptions as to future events. Actual results could differ from those estimates.

Concentration of Credit Risk

Concentration of credit risk

Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and accounts receivable.

We regularly maintain cash balances with various financial institutions that exceed federally insured amounts, but we have experienced no losses associated with these amounts to date.

The Company extends credit to customers in the normal course of business, often without requiring collateral. The Company performs credit analyses and monitors the financial health of its customers to reduce credit risk.

The Company’s accounts receivables are derived from revenue earned from customers primarily located in the U.S., Australia and in the Asia Pacific region. No countries other than the U.S. and Australia account for 10% or more of our revenue. Most of our customers are project developers, solar asset owners and engineering, procurement and construction (“EPC”) contractors that design and build solar energy projects. Often times, a small number of customers account for a significant portion of our outstanding receivables at period end and our total revenue for the year.

Stock-Based Compensation

Stock-based compensation

We recognize compensation expense for all share-based payment awards made, including stock options and restricted stock, based on the estimated fair value of the award on the grant date, in the accompanying condensed consolidated statements of comprehensive loss. We calculate the fair value of stock options using the Black-Scholes Option-Pricing model for awards with service-based vesting or through use of a lattice model or a Monte Carlo simulation for awards with market conditions. The fair value of restricted stock grants is based on the estimated fair value of the Company's common stock on the date of grant. Since completion of our IPO, we consider the closing price of our stock, as reported on the Nasdaq Global Market, to be the fair value of our stock on the grant date.

Forfeitures are accounted for as they occur. For service-based awards, stock-based compensation is recognized using the straight-line attribution approach over the requisite service period. For performance-based awards, stock-based compensation is recognized based on graded vesting over the requisite service period when the performance condition is probable of being achieved.

Revenue Recognition

Revenue recognition

Product revenue includes revenue from the sale of solar tracker systems and customized components of those systems, individual part sales for certain specific transactions, and sale of term-based software licenses. Term-based software licenses are deployed on the customers’ own servers and have significant standalone functionality.

Service revenue includes revenue from shipping and handling services, subscription fees from licensing subscription services, and maintenance and support services in connection with the term-based software licenses. Our subscription-based enterprise licensing model typically has contract terms ranging from one to two years and consists of subscription fees from the licensing of subscription services. Our hosted on-demand service arrangements do not provide customers with the right to take possession of the software supporting the hosted services. Support services include ongoing security updates, upgrades, bug fixes, and maintenance.

We recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services by following a five-step process, (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when or as the Company satisfies a performance obligation, as further described below.

Identify the contract with a customer: A contract with a customer exists when (i) the Company enters into an enforceable contract with a customer that defines each party’s rights regarding the products and services to be transferred and identifies the payment terms related to these products and services, (ii) the contract has commercial substance and, (iii) the Company determines that collection of substantially all consideration for products and services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. In assessing the recognition of revenue, we also evaluate whether two or more contracts should be combined and accounted for as one contract and if the combined or single contract should be accounted for as multiple performance obligations which could change the amount of revenue and profit (loss) recorded in a period. Change orders may include changes in specifications or design, manner of performance, equipment, materials, scope of work, and/or the period of completion of the project. We analyze change orders to determine if they should be accounted for as a modification to an existing contract or a new stand-alone contract.

Contracts we enter into with our customers for sale of solar tracker systems are generally under two different types of arrangements: (1) purchase agreements and equipment supply contracts (“Purchase Agreements”) and (2) sale of individual parts for those systems.

Change orders from our customers are generally modifications to existing contracts and are included in the total estimated contract revenue when it is probable that the change order will result in additional value that can be reliably estimated and realized.

Identify the performance obligations in the contract: We enter into contracts that can include various combinations of products and services, which are either capable of being distinct and accounted for as separate performance obligations or as one performance obligation since the majority of tasks and services are part of a single project or capability. However, determining whether products or services are considered distinct performance obligations that should be accounted for separately versus together may sometimes require significant judgment.

Our Purchase Agreements typically include two performance obligations- 1) our solar tracker systems or customized components of those systems, and 2) shipping and handling services. The deliverables included as part of our solar tracker systems are predominantly accounted for as one performance obligation, as these deliverables are part of a combined promise to deliver a project.

The revenue for shipping and handling services will be recognized over time based on progress in meeting shipping terms of the arrangements, as this faithfully depicts the Company’s performance in transferring control.

Sale of individual parts of our solar tracker systems for certain specific transactions includes multiple performance obligations consisting of individual parts of those systems. Revenue is recognized for parts sales at a point in time when the obligations under the terms of the contract with our customer are satisfied. Generally, this occurs with the transfer of control of the asset, which is in line with shipping terms.

Determine the transaction price: The transaction price is determined based on the consideration to which we will be entitled in exchange for transferring services to the customer. Such amounts are typically stated in the customer contract, and to the extent that we identify variable consideration, we will estimate the variable consideration at the onset of the arrangement as long as it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The majority of our contracts do not contain variable consideration provisions as a continuation of the original contract. None of our contracts contain a significant financing component. Taxes collected from customers and remitted to governmental authorities are not included in revenue.

Allocate the transaction price to performance obligations in the contract: Once we have determined the transaction price, we allocate the total transaction price to each performance obligation in a manner depicting the amount of consideration to which we expect to be entitled in exchange for transferring the good(s) or service(s) to the customer. We allocate the transaction price to each performance obligation identified in the contract on a relative standalone selling price basis.

We use the expected cost-plus margin approach based on hardware, labor, and related overhead cost to estimate the standalone selling price of our solar tracker systems, customized components of those systems, and individual parts for certain specific transactions. We use the adjusted market assessment approach for all other performance obligations except shipping, handling, and logistics. For shipping, handling, and logistics performance obligations, we use a residual approach to calculate the standalone selling price, because of the nature of the highly variable and broad range of prices we charge to various customers for this performance obligation in the contracts.

Recognize revenue when or as the Company satisfies a performance obligation: For each performance obligation identified, we determine at contract inception whether we satisfy the performance obligation over time or at a point in time. The performance obligations in the contracts for our solar tracker systems and customized components of those systems are satisfied over-time as work progresses, utilizing an input measure of progress determined by cost-to-cost measures on these projects as this faithfully depicts our performance in transferring control. Additionally, our performance does not create an asset with an alternative use, due to the highly customized nature of the product, and we have an enforceable right to payment for performance completed to date. Our performance obligations for individual part sales for certain specific transactions are recognized point-in-time as and when control transfers based on the Incoterms for the contract. Our performance obligations for term-based software licenses are recognized point-in-time as and when control transfers, either upon delivery to the customer or the software license start date, whichever is later. Our performance obligation for shipping and handling services is satisfied over-time as the services are delivered over the term of the contract. We recognize subscription services sales/other services on a straight-line basis over the contract period. With regard to support revenue, a time-elapsed method is used to measure progress because we transfer control evenly over the contractual period. Accordingly, the fixed consideration related to support revenue is generally recognized on a straight-line basis over the contract term.

Contract assets and liabilities: The timing of revenue recognition, billing, and cash collection results in the recognition of accounts receivable, unbilled receivables for revenue recognized in excess of billings, and deferred revenue in the Condensed Consolidated Balance Sheets. We may receive advances or deposits from our customers before revenue is recognized, resulting in contract liabilities, which are reflected as “deferred revenue” on our Condensed Consolidated Balance Sheets.

Cost of revenue consists primarily of costs related to raw materials, freight and delivery, product warranty, and personnel costs (salaries, bonuses, benefits, and stock-based compensation). Personnel costs in cost of revenue include both direct labor costs as well as costs attributable to any individuals whose activities relate to the procurement, installment, and delivery of the finished product and services. Personnel costs during 2021 are reported net of federal employee retention credits received. Deferred cost of revenue results from the timing differences between the costs incurred in advance of the satisfaction of all revenue recognition criteria consistent with our revenue recognition policy.

Warranty

Typically, the sale of solar tracker projects includes parts warranties to customers as part of the overall price of the product. We provide standard assurance type warranties for our products for periods generally ranging from two to ten years. We record a provision for estimated warranty expenses in cost of sales, net of amounts recoverable from manufacturers under their warranty obligations to us. We do not maintain general or unspecified reserves; all warranty reserves are related to specific projects. All actual or estimated material costs incurred for warranty services in subsequent periods are charged to those established reserves.

While we periodically monitor our warranty activities and claims, if actual costs incurred were to be different from our estimates, we would recognize adjustments to our warranty reserves in the period in which those differences arise or are identified.

Recent Accounting Pronouncements

Recent accounting pronouncements adopted and not yet adopted

Adopted

We adopted Accounting Standards Update ("ASU") 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contract in an Entity's Own Equity, effective January 1, 2022. This standard had no impact on our financial position or results operations at the time of adoption.

Not yet adopted

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 changes the impairment model for most financial assets and requires the use of an expected loss model in place of the currently used incurred loss method. Under this model, entities will be required to estimate the

lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. The update to the standard is effective for the Company for its fiscal year beginning after December 15, 2022, to the extent the Company remains an emerging growth company, and early adoption is permitted. We do not expect the adoption of ASU 2016-13 to have a material impact on our consolidated financial statements.
