This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Unless the context otherwise requires, the terms "Sunnova," "the Company," "we," "us" and "our" refer to Sunnova Energy International Inc. ("SEI") and its consolidated subsidiaries. Forward-looking statements generally relate to future events or Sunnova's future financial or operating performance. Actual outcomes and results may differ materially from what is expressed or forecast in such forward-looking statements. In some cases, you can identify these statements because they contain words such as "anticipate," "believe," "contemplate," "continue," "could," "estimate," "expect," "future," "goal," "intend," "likely," "may," "plan," "potential," "predict," "project," "seek," "should," "target," "will" or the negative of these words or other similar terms or expressions that concern our expectations, strategy, plans or intentions. Forward-looking statements contained in this report include, but are not limited to, statements about:

•our future operations and financial performance following the acquisition of SunStreet Energy Group, LLC, a Delaware limited liability company ("SunStreet");

•the effects of the coronavirus ("COVID-19") pandemic on our business and operations, results of operations and financial position;

•federal, state and local statutes, regulations and policies;

•determinations of the Internal Revenue Service ("IRS") of the fair market value of our solar energy systems;

•the price of centralized utility-generated electricity and electricity from other sources and technologies;

•technical and capacity limitations imposed by operators of the power grid;

•the availability of tax rebates, credits and incentives, including changes to the rates of, or expiration of, federal tax credits and the availability of related safe harbors;

•our need and ability to raise capital to finance the installation and acquisition of distributed residential solar energy systems, refinance existing debt or otherwise meet our liquidity needs;

•our expectations concerning relationships with third parties, including the attraction, retention, performance and continued existence of our dealers;

•our ability to manage our supply chains and distribution channels and the impact of natural disasters and other events beyond our control, such as the COVID-19 pandemic;

•our ability to retain or upgrade current customers, further penetrate existing markets or expand into new markets;

•our investment in our platform and new product offerings and the demand for and expected benefits of our platform and product offerings;

•the ability of our solar energy systems, energy storage systems or other product offerings to operate or deliver energy for any reason, including if interconnection or transmission facilities on which we rely become unavailable;

•our ability to maintain our brand and protect our intellectual property and customer data;

•our ability to manage the cost of solar energy systems, energy storage systems and our service offerings;

•the willingness of and ability of our dealers and suppliers to fulfill their respective warranty and other contractual obligations;

•our expectations regarding litigation and administrative proceedings; and

•our ability to renew or replace expiring, canceled or terminated solar service agreements at favorable rates or on a long-term basis.

Our actual results and timing of these events may differ materially from those anticipated in these forward-looking statements as a result of many factors, including but not limited to those discussed under "Risk Factors" and elsewhere in this Quarterly Report on Form 10-Q. Moreover, we operate in a very competitive and rapidly changing environment and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this Quarterly Report on Form 10-Q may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this Quarterly Report on Form 10-Q to conform these statements to actual results or to changes in our expectations, except as required by law.

We are a leading residential energy service provider, serving over 224,000 customers in more than 35 United States ("U.S.") states and territories. Sunnova Energy Corporation was incorporated in Delaware on October 22, 2012 and formed Sunnova Energy International Inc. ("SEI") as a Delaware corporation on April 1, 2019. We completed our initial public offering on July 29, 2019 (our "IPO"); and in connection with our IPO, all of Sunnova Energy Corporation's ownership interests were contributed to SEI. Unless the context otherwise requires, references in this report to "Sunnova," the "Company," "we," "our," "us," or like terms, refer to SEI and its consolidated subsidiaries.

We have a differentiated residential solar dealer model in which we partner with local dealers who originate, design and install our customers' solar energy systems, energy storage systems and related products and services on our behalf. Our focus on our dealer model enables us to leverage our dealers' specialized knowledge, connections and experience in local markets to drive customer origination while providing our dealers with access to high quality products at competitive prices, as well as technical oversight and expertise. We believe this structure provides operational flexibility, reduces exposure to labor shortages and lowers fixed costs relative to our peers, furthering our competitive advantage.

We provide our services through long-term agreements with a diversified pool of credit quality customers. Our solar service agreements typically are structured as either a legal-form lease (a "lease") of a solar energy system and/or energy storage system to the customer, the sale of the solar energy system's output to the customer under a power purchase agreement ("PPA") or the purchase of a solar energy system and/or energy storage system with financing provided by us (a "loan"); however, we also offer service plans for systems we did not originate. We make it possible in some states for a customer to obtain a new roof and other ancillary products as part of their solar loan. We also allow customers originated through our homebuilder channel the option of purchasing the system when the customer closes on the purchase of a new home. The initial term of our solar service agreements is typically between 10 and 25 years, during which time we provide or arrange for ongoing services to customers, including monitoring, maintenance and warranty services. Our lease and PPA agreements typically include an opportunity for customers to renew for up to an additional 10 years, via two five-year or one 10-year renewal options. Customer payments and rates can be fixed for the duration of the solar service agreement or escalated at a pre-determined percentage annually. We also receive tax benefits and other incentives from leases and PPAs, a portion of which we finance through tax equity, non-recourse debt structures and hedging arrangements in order to fund our upfront costs, overhead and growth investments. Our future success depends in part on our ability to raise capital from third-party investors and commercial sources. We have an established track record of attracting capital from diverse sources. From our inception through June 30, 2022, we have raised more than $9.8 billion in total capital commitments from equity, debt and tax equity investors.

Basis of Presentation

The accompanying interim unaudited condensed consolidated financial statements ("interim financial statements") include our consolidated balance sheets, statements of operations, statements of redeemable noncontrolling interests and equity and statements of cash flows and have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") from records maintained by us. We have condensed or omitted certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP pursuant to the applicable rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. As such, these interim financial statements should be read in conjunction with our 2021 annual audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K filed with the SEC on February 24, 2022. Our interim financial statements reflect all normal recurring adjustments necessary, in our opinion, to state fairly our financial position and results of operations for the reported periods. Amounts reported for interim periods may not be indicative of a full year period because of our continual growth, seasonal fluctuations in demand for power, timing of maintenance and other expenditures, changes in interest expense and other factors.

Our interim financial statements include our accounts and those of our subsidiaries in which we have a controlling financial interest. In accordance with the provisions of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 810, Consolidation, we consolidate any VIE of which we are the primary beneficiary. We form VIEs with our investors in the ordinary course of business to facilitate the funding and monetization of certain attributes associated with our solar energy systems. The typical condition for a controlling financial interest is holding a majority of the voting interests of an entity. However, a controlling financial interest may also exist in entities, such as VIEs, through arrangements that do not involve holding a majority of the voting interests. A primary beneficiary is defined as the party that has (a) the power to direct the activities of a VIE that most significantly impact the VIE's economic performance and (b) the obligation to absorb losses or receive benefits from the VIE that could potentially be significant to the VIE. We do not consolidate a VIE in which we have a majority ownership interest when we are not considered the primary beneficiary. We

10

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

have considered the provisions within the contractual arrangements that grant us power to manage and make decisions that affect the operation of our VIEs, including determining the solar energy systems contributed to the VIEs, and the installation, operation and maintenance of the solar energy systems. We consider the rights granted to the other investors under the contractual arrangements to be more protective in nature rather than substantive participating rights. As such, we have determined we are the primary beneficiary of our VIEs and evaluate our relationships with our VIEs on an ongoing basis to determine whether we continue to be the primary beneficiary. We have eliminated all intercompany transactions in consolidation.

Coronavirus ("COVID-19") Pandemic

The ongoing COVID-19 pandemic has resulted and may continue to result in widespread adverse impacts on the global economy. We have experienced some resulting disruptions to our business operations as the COVID-19 virus has continued to circulate through the states and U.S. territories in which we operate.

Throughout the COVID-19 pandemic, we have continued to service and install solar energy systems and energy storage systems. The industry is currently facing shortages and shipping delays affecting the supply of energy storage systems, modules and component parts for inverters and racking used in solar energy systems available for purchase. These shortages and delays can be attributed in part to the COVID-19 pandemic and resulting government action, as well as to allegations regarding the use of forced labor in the Chinese polysilicon supply chain. While a majority of our dealers have secured sufficient quantities to permit them to continue installing through much of 2022, if these shortages and delays persist, they could impact the timing of when solar energy systems and energy storage systems can be installed and when we can acquire and begin to generate revenue from those systems. In addition, if supply chains become significantly disrupted due to additional outbreaks of the COVID-19 virus or otherwise, or more stringent health and safety guidelines are implemented, our ability to install and service solar energy systems and energy storage systems could become adversely impacted. We cannot predict the full impact the COVID-19 pandemic will have on our business, cash flows, liquidity, financial condition and results of operations at this time due to numerous uncertainties. We will continue to monitor developments affecting our workforce, our customers and our business operations generally, and will take actions we determine are necessary in order to mitigate these impacts.

(2) Significant Accounting Policies

Included below are updates to significant accounting policies disclosed in our 2021 annual audited consolidated financial statements.

Use of Estimates

The application of GAAP in the preparation of the interim financial statements requires us to make estimates and assumptions that affect the amounts reported in the interim financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ materially from those estimates.

Accounts Receivable

Accounts Receivable—Trade.    Accounts receivable—trade primarily represents trade receivables from residential customers that are generally collected in the subsequent month. Accounts receivable—trade is recorded net of an allowance for credit losses, which is based on our assessment of the collectability of customer accounts based on the best available data at the time. We review the allowance by considering factors such as historical experience, customer credit rating, contractual term, aging category and current economic conditions that may affect a customer's ability to pay to identify customers with potential disputes or collection issues. We write off accounts receivable when we deem them uncollectible. As of June 30, 2022, we have not experienced a significant increase in delinquent customer accounts and have not made any significant adjustments to our allowance for credit losses related to accounts receivable—trade as a result of the COVID-19 pandemic. The following table

Accounts Receivable—Other.    Accounts receivable—other primarily represents receivables from our dealers or other parties related to the sale of inventory and the use of inventory procured by us.

Inventory

Inventory is stated at the lower of cost and net realizable value using the first-in, first-out method. Inventory primarily represents (a) raw materials, such as energy storage systems, photovoltaic modules, inverters, meters and modems, (b) homebuilder construction in progress and (c) other associated equipment purchased. These materials are typically procured by us and used by our dealers, sold to our dealers or held for use as original parts on new solar energy systems or replacement parts on existing solar energy systems. We remove these items from inventory and record the transaction in typically one of these manners: (a) expense to operations and maintenance expense when installed as a replacement part for a solar energy system, (b) recognize in accounts receivable—other when procured by us and used by our dealers, (c) expense to cost of revenue if sold directly to a dealer or other party, (d) capitalize to property and equipment when installed on an existing home or (e) capitalize to property and equipment when placed in service under the homebuilder program. We periodically evaluate our inventory for unusable and obsolete items based on assumptions about future demand and market conditions. Based on this evaluation, provisions are made to write inventory down to market value. The following table presents the detail of inventory as recorded in other current assets in the unaudited condensed consolidated balance sheets:

Fair Value of Financial Instruments

Fair value is an exit price representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions market participants would use in pricing an asset or a liability. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820 establishes a three-tier fair value hierarchy, which prioritizes inputs that may be used to measure fair value as follows:

•Level 1—Observable inputs that reflect unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.

•Level 2—Observable inputs other than Level 1 prices, such as quoted market prices for similar assets or liabilities in active markets, quoted market prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

12

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

•Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy must be determined based on the lowest level input that is significant to the fair value measurement. An assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the asset or liability. Our financial instruments include cash, accounts receivable, customer notes receivable, investments in solar receivables, accounts payable, accrued expenses, long-term debt, interest rate swaps and contingent consideration. The carrying values of accounts receivable, accounts payable and accrued expenses approximate the fair values due to the fact that they are short-term in nature and based on quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date (Level 1). We estimate the fair value of our customer notes receivable based on interest rates currently offered under the loan program with similar maturities and terms (Level 3). We estimate the fair value of our investments in solar receivables based on a discounted cash flows model that utilizes market data related to solar irradiance, production factors by region and projected electric utility rates in order to build up revenue projections (Level 3). In addition, lease-related revenue and maintenance and service costs were supported through the use of available market studies and data. We estimate the fair value of our fixed-rate long-term debt based on interest rates currently offered for debt with similar maturities and terms (Level 3). We determine the fair values of the interest rate derivative transactions based on a discounted cash flow method using contractual terms of the transactions. The floating interest rate is based on observable rates consistent with the frequency of the interest cash flows (Level 2). For contingent consideration, we estimate the fair value of the installation earnout using the Monte Carlo model based on the forecasted placements for the installations and the microgrid earnout using a scenario-based methodology based on the probabilities of the microgrid earnout, both using Level 3 inputs. See Note 6, Customer Notes Receivable, Note 7, Long-Term Debt and Note 8, Derivative Instruments.

We recognize revenue from contracts with customers as we satisfy our performance obligations at a transaction price reflecting an amount of consideration based upon an estimated rate of return, net of cash incentives. We express this rate of return as the solar rate per kilowatt hour ("kWh") in the customer contract. The amount of revenue we recognize does not equal customer cash payments because we satisfy performance obligations ahead of cash receipt or evenly as we provide continuous access on a stand-ready basis to the solar energy system. We reflect the differences between revenue recognition and cash payments received in accounts receivable, other assets or deferred revenue, as appropriate. Revenue allocated to remaining performance obligations represents contracted revenue we have not yet recognized and includes deferred revenue as well as amounts that will be invoiced and recognized as revenue in future periods. Contracted but not yet recognized revenue was approximately $2.6 billion as of June 30, 2022, of which we expect to recognize approximately 4% over the next 12 months.

14

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

We do not expect the annual recognition to vary significantly over approximately the next 20 years as the vast majority of existing solar service agreements have at least 20 years remaining, given the average age of the fleet of solar energy systems under contract is less than four years.

Certain customers may receive cash incentives. We defer recognition of the payment of these cash incentives and recognize them over the life of the contract as a reduction to revenue. The deferred payment is recorded in other assets for customers who receive the cash incentives under our lease and PPA agreements, and as a contra-liability in other long-term liabilities for customers who receive the cash incentives under our loan agreements.

PPAs.    Customers purchase electricity from us under PPAs. Pursuant to ASC 606, we recognize revenue based upon the amount of electricity delivered as determined by remote monitoring equipment at solar rates specified under the PPAs. All customers must pass our credit evaluation process. The PPAs generally have a term of 20 or 25 years with an opportunity for customers to renew for up to an additional 10 years, via two five-year or one 10-year renewal options.

Leases.    We are the lessor under lease agreements for solar energy systems and energy storage systems, which do not meet the definition of a lease under ASC 842 and are accounted for as contracts with customers under ASC 606. We recognize revenue on a straight-line basis over the contract term as we satisfy our obligation to provide continuous access to the solar energy system. All customers must pass our credit evaluation process. The lease agreements generally have a term of 20 or 25 years with an opportunity for customers to renew for up to an additional 10 years, via two five-year or one 10-year renewal options.

In most cases, we provide customers under our lease agreements a performance guarantee that each solar energy system will achieve a certain specified minimum solar energy production output, which is a significant proportion of its expected output. The specified minimum solar energy production output may not be achieved due to natural fluctuations in the weather or equipment failures from exposure and wear and tear outside of our control, among other factors. We determine the amount of the guaranteed output based on a number of different factors, including: (a) the specific site information relating to the tilt of the panels, azimuth (a horizontal angle measured clockwise in degrees from a reference direction) of the panels, size of the system, and shading on site; (b) the calculated amount of available irradiance (amount of energy for a given flat surface facing a specific direction) based on historical average weather data and (c) the calculated amount of energy output of the solar energy system. While actual irradiance levels can significantly change year over year due to natural fluctuations in the weather, we expect the levels to average out over the term of a lease and to approximate the levels used in determining the amount of the performance guarantee. Generally, weather fluctuations are the most likely reason a solar energy system may not achieve a certain specified minimum solar energy production output.

If the solar energy system does not produce the guaranteed production amount, we are required to refund a portion of the previously remitted customer payments, where the repayment is calculated as the product of (a) the shortfall production amount and (b) the dollar amount (guaranteed rate) per kWh that is fixed throughout the term of the contract. These remittances of a customer's payments, if needed, are payable as early as the first anniversary of the solar energy system's placed in service date and then every annual period thereafter. See Note 14, Commitments and Contingencies.

Inventory Sales.    Inventory sales revenue represents revenue from the direct sale of inventory to our dealers or other parties. We recognize the related revenue under ASC 606 upon shipment. Shipping and handling costs are included in cost of revenue—inventory sales in the consolidated statements of operations.

Solar Renewable Energy Certificates.    Each solar renewable energy certificate ("SREC") represents the environmental benefit of one megawatt hour (1,000 kWh) generated by a solar energy system. SRECs can be sold separate from the actual electricity generated by the renewable-based generation source. We account for the SRECs we generate from our solar energy systems as governmental incentives with no costs incurred to obtain them and do not consider those SRECs output of the underlying solar energy systems. We classify these SRECs as inventory held until sold and delivered to third parties. As we did not incur costs to obtain these governmental incentives, the inventory carrying value for the SRECs was $0 as of June 30, 2022 and December 31, 2021. We enter into economic hedges related to expected production of SRECs through forward contracts. While these fixed price forward contracts serve as an economic hedge against spot price fluctuations for the SRECs, the contracts do not qualify for hedge accounting and are not designated as cash flow hedges or fair value hedges. The contracts require us to physically deliver the SRECs upon settlement. We recognize the related revenue under ASC 606 upon satisfaction of the performance obligation to transfer the SRECs to the stated counterparty. Payments are typically received within one month of transferring the SREC to the counterparty. The costs related to the sales of SRECs are generally limited to broker fees (recorded in cost of revenue—other), which are only paid in connection with certain transactions. In certain circumstances we are required to purchase SRECs on the open market to fulfill minimum delivery requirements under our forward contracts.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Cash Sales.    Cash sales revenue represents revenue from a customer's purchase of a solar energy system from us typically when purchasing a new home. We recognize the related revenue under ASC 606 upon verification of the home closing.

Loans.    See discussion of loan revenue in the "Loans" section below.

Other Revenue.    Other revenue includes certain state and utility incentives, revenue from the direct sale of solar energy systems and energy storage systems to customers with financing provided by us and sales of service plans. We recognize revenue from state and utility incentives in the periods in which they are earned. We recognize revenue from the direct sale of energy storage systems in the period in which the storage components are placed in service. Service plans are available to customers whose solar energy system was not originally sold by Sunnova. We recognize revenue from service plan contracts on a straight-line basis over the life of the contract, which is typically 10 years.

Loans

We offer a loan program, under which the customer finances the purchase of a solar energy system or energy storage system through a solar service agreement, typically for a term of 10, 15 or 25 years. We recognize cash payments received from customers on a monthly basis under our loan program (a) as interest income, to the extent attributable to earned interest on the contract that financed the customer's purchase of the solar energy system or energy storage system; (b) as a reduction of a note receivable on the balance sheet, to the extent attributable to a return of principal (whether scheduled or prepaid) on the contract that financed the customer's purchase of the solar energy system or energy storage system; and (c) as revenue, to the extent attributable to payments for operations and maintenance services provided by us. To qualify for the loan program, a customer must pass our credit evaluation process, which requires the customer to have a minimum FICO® score of 600 to 780 depending on certain circumstances, and we secure the loans with the solar energy systems or energy storage systems financed. The credit evaluation process is performed once for each customer at the time the customer is entering into the solar service agreement with us.

Our investments in solar energy systems and energy storage systems related to the loan program that are not yet placed in service are recorded in other assets in the consolidated balance sheets and are transferred to customer notes receivable upon being placed in service. Customer notes receivable are recorded at amortized cost, net of an allowance for credit losses (as described below), in other current assets and customer notes receivable in the consolidated balance sheets. Accrued interest receivable related to our customer notes receivable is recorded in accounts receivable—trade, net in the consolidated balance sheets. Interest income from customer notes receivable is recorded in interest income in the consolidated statements of operations. The amortized cost of our customer notes receivable is equal to the principal balance of customer notes receivable outstanding and does not include accrued interest receivable. Customer notes receivable continue to accrue interest until they are written off against the allowance, which occurs when the balance is 180 days or more past due unless the balance is in the process of collection. Customer notes receivable are considered past due one day after the due date based on the contractual terms of the loan agreement. In all cases, customer notes receivable balances are placed on a nonaccrual status or written off at an earlier date when they are deemed uncollectible. Expected recoveries do not exceed the aggregate of amounts previously written off and expected to be written off. Accrued interest receivable for customer notes receivable placed on a nonaccrual status is recorded as a reduction to interest income. Interest received on such customer notes receivable is accounted for on a cash basis until the customer notes receivable qualifies for the return to accrual status. Customer notes receivable are returned to accrual status when there is no longer any principal or interest amounts past due and future payments are reasonably assured.

The allowance for credit losses is deducted from the customer notes receivable amortized cost to present the net amount expected to be collected. It is measured on a collective (pool) basis when similar risk characteristics (such as financial asset type, customer credit rating, contractual term and vintage) exist. In determining the allowance for credit losses, we identify customers with potential disputes or collection issues and consider our historical level of credit losses and current economic trends that might impact the level of future credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics, such as differences in underwriting standards. Expected credit losses are estimated over the contractual term of the loan agreements based on the best available data at the time and adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless either of the following applies: (a) we have a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual customer or (b) the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by us. As of June 30, 2022, we have not experienced a significant increase in delinquent customer notes receivable and have not made any significant adjustments to our allowance for credit losses related to loans as a result of the COVID-19 pandemic. See Note 6, Customer Notes Receivable.

Deferred Revenue

Deferred revenue consists of amounts for which the criteria for revenue recognition have not yet been met and includes (a) payments for unfulfilled performance obligations which will be recognized on a straight-line basis over the remaining term of the respective solar service agreements, net of any cash incentives earned by the customers, (b) down payments and partial or full prepayments from customers and (c) differences due to the timing of energy production versus billing for certain types of PPAs. Deferred revenue was $106.8 million as of December 31, 2020. The following table presents the detail of deferred revenue as recorded in other current liabilities and other long-term liabilities in the unaudited condensed consolidated balance sheets:

(1) Of this amount, $21.3 million and $15.3 million is recorded in other current liabilities as of June 30, 2022 and December 31, 2021, respectively.

During the six months ended June 30, 2022 and 2021, we recognized revenue of $8.1 million and $4.7 million, respectively, from amounts recorded in deferred revenue at the beginning of the respective years.

New Accounting Guidance

New accounting pronouncements are issued by the FASB or other standard setting bodies and are adopted as of the specified effective date.

In March 2022, the FASB issued Accounting Standards Update ("ASU") No. 2022-02, Financial Instruments—Credit Losses: Troubled Debt Restructurings and Vintage Disclosures, to eliminate the accounting guidance for troubled debt restructurings while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. This ASU is effective for annual and interim reporting periods beginning in January 2023. We are currently evaluating the impact of this ASU on our consolidated financial statements and related disclosures.

(5) Asset Retirement Obligations ("ARO")

AROs consist primarily of costs to remove solar energy system assets and costs to restore the solar energy system sites to the original condition, which we estimate based on current market rates. For each solar energy system, we recognize the fair value of the ARO as a liability and capitalize that cost as part of the cost basis of the related solar energy system. The related assets are depreciated on a straight-line basis over 30 years, which is the estimated average time a solar energy system will be installed in a location before being removed, and the related liabilities are accreted to the full value over the same period of time. We revise our estimated future liabilities based on recent actual experiences, including third party cost estimates, average size of solar energy systems and inflation rates, which we evaluate at least annually. Changes in our estimated future liabilities are recorded as either a reduction or addition in the carrying amount of the remaining unamortized asset and the ARO and either decrease or increase our depreciation and accretion expense amounts prospectively.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Availability.    As of June 30, 2022, we had $277.7 million of available borrowing capacity under our various financing arrangements, consisting of $30.0 million under the EZOP revolving credit facility, $187.7 million under the TEPH revolving credit facility and $60.0 million under the AP8 revolving credit facility. There was no available borrowing capacity under any of our other financing arrangements. As of June 30, 2022, we were in compliance with all debt covenants under our financing arrangements.

Weighted Average Effective Interest Rates.    The weighted average effective interest rates disclosed in the table above are the weighted average stated interest rates for each debt instrument plus the effect on interest expense for other items classified as interest expense, such as the amortization of deferred financing costs, amortization of debt discounts and commitment fees on unused balances for the period of time the debt was outstanding during the indicated periods.

HELVIII Debt.    In February 2022, we pooled and transferred eligible solar loans and the related receivables into HELVIII, a special purpose entity, that issued $131.9 million in aggregate principal amount of Series 2022-A Class A solar loan-backed notes, $102.2 million in aggregate principal amount of Series 2022-A Class B solar loan-backed notes and $63.8 million in aggregate principal amount of Series 2022-A Class C solar loan-backed notes (collectively, the "HELVIII Notes") with a maturity date of February 2049. The HELVIII Notes were issued at a discount of 1.55% for Class A, 2.23% for Class B and 2.62% for Class C and bear interest at an annual rate of 2.79%, 3.13% and 3.53%, respectively. The cash flows generated by these solar loans are used to service the monthly principal and interest payments on the HELVIII Notes and satisfy HELVIII's expenses, and any remaining cash can be distributed to Sunnova Helios VIII Depositor, LLC, HELVIII's sole member. In connection with the HELVIII Notes, certain of our affiliates receive a fee for managing and servicing the solar energy systems pursuant to management and service agreements. In addition, Sunnova Energy Corporation has guaranteed, among other things, (a) the obligations of certain of our subsidiaries to manage and service the solar energy systems pursuant to management and servicing agreements and (b) certain of our subsidiaries' obligations to repurchase or substitute certain ineligible solar loans eventually sold to HELVIII pursuant to the related sale and contribution agreement. HELVIII is also required to maintain certain reserve accounts for the benefit of the holders of the HELVIII Notes, each of which must be funded at all times to the levels specified in the HELVIII Notes. The holders of the HELVIII Notes have no recourse to our other assets except as expressly set forth in the HELVIII Notes.

EZOP Debt.    In June 2022, we amended the EZOP revolving credit facility to, among other things, (a) extend the scheduled commitment termination date to May 2024, (b) extend the facility maturity date to November 2024, (c) increase the aggregate commitment amount from $200.0 million to $400.0 million, subject to reductions based on the outstanding principal balance of advances over certain time periods, (d) increase the maximum facility amount from $350.0 million to $475.0 million, (e) modify the interest rate on borrowings from accruing based on the London Inter-Bank Offered Rate to accruing based on a forward-looking term rate based on the secured overnight financing rate ("Term SOFR"), plus a Term SOFR spread adjustment, (f) add an amortization event relating to certain of our subsidiaries ceasing to originate solar loans (subject to certain thresholds, time periods and exceptions set forth therein), (g) add concentration limits for solar loans (1) with obligors with credit scores below certain thresholds and (2) for which the original principal balance exceeds a certain threshold and (h) modify eligibility requirements for solar loans to increase the permitted maximum original principal balance.

SOLIV Debt.    In June 2022, we pooled and transferred eligible solar energy systems and the related asset receivables into wholly-owned subsidiaries of SOLIV, a special purpose entity, that issued $317.0 million in aggregate principal amount of Series 2022-1 Class A solar asset-backed notes and $38.0 million in aggregate principal amount of Series 2022-1 Class B solar asset-backed notes (collectively, the "SOLIV Notes") with a maturity date of April 2057. The SOLIV Notes were issued at a discount of 3.55% and 2.10%, respectively, and bear interest at an annual rate equal to 4.95% and 6.35%, respectively. The cash flows generated by the solar energy systems of SOLIV's subsidiaries are used to service the quarterly principal and interest payments on the SOLIV Notes and satisfy SOLIV's expenses, and any remaining cash can be distributed to Sunnova Sol IV Depositor, LLC, SOLIV's sole member. In connection with the SOLIV Notes, certain of our affiliates receive a fee for managing and servicing the solar energy systems pursuant to a transaction management agreement and management and servicing agreements. In addition, Sunnova Energy Corporation has guaranteed (a) the obligations of certain of our subsidiaries to manage and service the solar energy systems pursuant to a transaction management agreement and management and servicing agreements, (b) the managing members' obligations, in such capacity, under the related financing fund's limited liability company agreement and (c) certain of our subsidiaries' obligations to repurchase or substitute certain ineligible solar energy systems eventually sold to SOLIV pursuant to the sale and contribution agreement. SOLIV is also required to maintain certain reserve accounts for the benefit of the holders of the SOLIV Notes, each of which must remain funded at all times to the levels specified in the SOLIV Notes. The indenture requires SOLIV to track the debt service coverage ratio (such ratio, the "DSCR") of (a) the amount of certain payments received from customers, certain performance based incentives, certain energy credits and any applicable insurance proceeds as of a specific date to (b) interest and scheduled principal due on the SOLIV Notes as of such date, with the potential to enter into an early amortization period if the DSCR drops below a certain threshold. The holders of the SOLIV Notes have no recourse to our other assets except as expressly set forth in the SOLIV Notes.

(8) Derivative Instruments

Interest Rate Swaps and Caps on EZOP Debt.    During the six months ended June 30, 2022 and 2021, EZOP entered into interest rate swaps and caps for an aggregate notional amount of $340.6 million and $180.2 million, respectively, to economically hedge its exposure to the variable interest rates on a portion of the outstanding EZOP debt. No collateral was posted for the interest rate swaps and caps as they are secured under the EZOP revolving credit facility. In July 2022, the notional amount of the interest rate swaps and caps began decreasing to match EZOP's estimated monthly principal payments on the debt. During the six months ended June 30, 2022 and 2021, EZOP unwound interest rate swaps and caps with an aggregate notional amount of $360.2 million and $131.7 million, respectively, and recorded a realized gain of $15.7 million and a realized loss of $68,000, respectively.

Interest Rate Swaps and Caps on TEPH Debt.    During the six months ended June 30, 2022 and 2021, TEPH entered into interest rate swaps and caps for an aggregate notional amount of $421.1 million and $115.1 million, respectively, to economically hedge its exposure to the variable interest rates on a portion of the outstanding TEPH debt. No collateral was posted for the interest rate swaps and caps as they are secured under the TEPH revolving credit facility. In October 2023, the notional amount of the interest rate swaps will begin decreasing to match TEPH's estimated quarterly principal payments on the debt.

(9) Income Taxes

Our effective income tax rate is 0% for the three and six months ended June 30, 2022 and 2021. Total income tax differs from the amounts computed by applying the statutory income tax rate to loss before income tax primarily as a result of our valuation allowance. We assessed whether we had any significant uncertain tax positions taken in a filed tax return, planned to be taken in a future tax return or claim, or otherwise subject to interpretation and determined there were none not more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position, or prospectively approved when such approval may be sought in advance. Accordingly, we recorded no reserve for uncertain tax positions. Should a provision for any interest or penalties relative to unrecognized tax benefits be necessary, it is our policy to accrue for such in our income tax accounts. There were no such accruals as of June 30, 2022 and December 31, 2021 and we do not expect a significant change in gross unrecognized tax benefits in the next twelve months. Our tax years after 2011 remain subject to examination by the Internal Revenue Service and by the taxing authorities in the states and territories in which we operate.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis contain forward-looking statements that are subject to risks, uncertainties and assumptions. Our actual results and timing of selected events may differ materially from those anticipated in these forward-looking statements as a result of many factors, including but not limited to those discussed under "Special Note Regarding Forward-Looking Statements" above and "Special Note Regarding Forward-Looking Statements", "Risk Factors" and elsewhere in our Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on February 24, 2022, our Quarterly Report on Form 10-Q filed with the SEC on April 28, 2022 and elsewhere in this Quarterly Report on Form 10-Q. Moreover, we operate in a very competitive and rapidly changing environment and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this Quarterly Report on Form 10-Q may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. Unless the context otherwise requires, the terms "Sunnova," "the Company," "we," "us" and "our" refer to SEI and its consolidated subsidiaries.

Company Overview

We are a leading residential energy service provider, serving over 224,000 customers in more than 35 United States ("U.S.") states and territories. Our goal is to be the source of clean, affordable and reliable energy with a simple mission: to power energy independence so homeowners have the freedom to live life uninterrupted. We were founded to deliver customers a better energy service at a better price; and, through our energy service offerings, we are disrupting the traditional energy landscape and the way the 21st century customer generates and consumes electricity.

We have a differentiated residential solar dealer model in which we partner with local dealers who originate, design and install our customers' solar energy systems, energy storage systems and related products and services on our behalf. Our focus on our dealer model enables us to leverage our dealers' specialized knowledge, connections and experience in local markets to drive customer origination while providing our dealers with access to high quality products at competitive prices, as well as technical oversight and expertise. We believe this structure provides operational flexibility, reduces exposure to labor shortages and lowers fixed costs relative to our peers, furthering our competitive advantage.

We offer customers products to power their homes with affordable solar energy and related products and services. We are able to offer savings compared to utility-based retail rates with little to no up-front expense to the customer in conjunction with solar and solar plus energy storage, and, in the case of the latter, are able to also provide energy resiliency. Our solar service agreements typically take the form of a lease, power purchase agreement ("PPA") or loan; however, we also offer service plans for systems we did not originate. We make it possible in some states for a customer to obtain a new roof and other ancillary products as part of their solar loan. We also allow customers originated through our homebuilder channel the option of purchasing the system when the customer closes on the purchase of a new home. The initial term of our solar service agreements is typically between 10 and 25 years. Service is an integral part of our agreements and includes operations and maintenance, monitoring, repairs and replacements, equipment upgrades, on-site power optimization for the customer (for both supply and demand), the ability to efficiently switch power sources among the solar panel, grid and energy storage system, as appropriate, and diagnostics. During the life of the contract, we have the opportunity to integrate related and evolving home servicing and monitoring technologies to upgrade the flexibility and reduce the cost of our customers' energy supply.

In the case of leases and PPAs, we also currently receive tax benefits and other incentives from federal, state and local governments, a portion of which we finance through tax equity, non-recourse debt structures and hedging arrangements in order to fund our upfront costs, overhead and growth investments. We have an established track record of attracting capital from diverse sources. From our inception through June 30, 2022, we have raised more than $9.8 billion in total capital commitments from equity, debt and tax equity investors.

In addition to providing ongoing service as a standard component of our solar service agreements, we also offer ongoing energy services to customers who purchased their solar energy system through third parties. Under these arrangements, we agree to provide monitoring, maintenance and repair services to these customers for the life of the service contract they sign with us. We also offer complimentary products to our agreements as well as non-solar financing. Specifically, our offerings include a non-solar loan program enabling customers to finance the purchase of products independent of a solar energy system or energy storage system. We believe the quality and scope of our comprehensive energy service offerings, whether to customers that obtained their solar energy system through us or through another party, is a key differentiator between us and our competitors.

32

In April 2021, we acquired SunStreet, Lennar Corporation's ("Lennar") residential solar platform that focuses primarily on solar energy systems and energy storage systems for homebuilders. In connection with that acquisition, we entered into an agreement pursuant to which we would be the exclusive residential solar and storage provider for Lennar's new home communities with solar across the U.S. for a period of four years. We believe the acquisition provides a new strategic path to further scale our residential solar business, reduces customer acquisition costs, provides a multi-year supply of homesites through the development of new home solar communities and allows us to pursue the development of clean and resilient residential microgrids across the U.S.

We also enter into leases with third-party owners of pools of solar energy systems to receive such third party's interest in those systems. In connection therewith, we assume the related customer PPA and lease obligations, entitling us to future customer cash flows as well as certain credits, rebates and incentives (including SRECs) under those agreements, in exchange for a lease payment, whether upfront or over time, to the third-party owner, which may be made in the form of cash or shares of our common stock. We believe such arrangements enhance our long-term contracted cash flows and are complementary to our overall business model.

We commenced operations in January 2013 and began providing solar energy services under our first solar energy system in April 2013. Since then, our brand, innovation and focused execution have driven significant, rapid growth in our market share and in the number of customers on our platform. We operate one of the largest fleets of residential solar energy systems in the U.S., comprising more than 1,351 megawatts of generation capacity and serving over 224,000 customers.

Recent Developments

COVID-19 Pandemic

The ongoing COVID-19 pandemic has resulted and may continue to result in widespread adverse impacts on the global economy. We have experienced some resulting disruptions to our business operations as the COVID-19 virus has continued to circulate through the states and U.S. territories in which we operate.

Social distancing guidelines, stay-at-home orders and similar measures associated with the COVID-19 pandemic, as well as actions by individuals to reduce their potential exposure to the virus, contributed to a decline in origination. This decline reflected an inability by our dealers to perform in-person sales calls based on the stay-at-home orders in some locations. To adjust to these government measures, our dealers expanded the use of digital tools and origination channels and created new methods that offset restrictions on their ability to meet with potential new customers in person. Such efforts drove an increase in new contract origination. We have seen the use of websites, video conferencing and other virtual tools as part of our origination process expand widely and contribute to our growth.

Throughout the COVID-19 pandemic, we have continued to service and install solar energy systems and energy storage systems. The industry is currently facing shortages and shipping delays affecting the supply of energy storage systems, modules and component parts for inverters and racking used in solar energy systems. These shortages and delays can be attributed in part to the COVID-19 pandemic and to government action in response to the pandemic, as well as to allegations regarding the use of forced labor in the Chinese polysilicon supply chain. While a majority of our dealers have secured sufficient quantities to permit them to continue installing and conducting repairs through much of 2022, if these shortages and delays persist, they could impact the timing of when solar energy systems and energy storage systems can be installed and repaired and when we can acquire and begin to generate revenue from those systems. In addition, if supply chains become significantly disrupted due to additional outbreaks of the COVID-19 virus or otherwise, or more stringent health and safety guidelines are implemented, our ability to install and service solar energy systems and energy storage systems could become adversely impacted.

We cannot predict the full impact the COVID-19 pandemic will have on our business, cash flows, liquidity, financial condition and results of operations at this time due to numerous uncertainties. We will continue to monitor developments affecting our workforce, our customers and our business operations generally, and will take actions we determine are necessary in order to mitigate these impacts.

Financing Transactions

In May 2022, we admitted a tax equity investor with a total capital commitment of approximately $17.5 million. See "—Liquidity and Capital Resources—Financing Arrangements—Tax Equity Fund Commitments" below.

In June 2022, we amended a revolving credit facility to, among other things, (a) extend the scheduled commitment termination date to May 2024, (b) extend the facility maturity date to November 2024 and (c) increase the aggregate

33

commitment amount from $200.0 million to $400.0 million, subject to reductions based on the outstanding principal balance of advances over certain time periods. In July 2022, we further amended this revolving credit facility to, among other things, increase the uncommitted maximum facility amount from $475.0 million to $535.0 million until the earlier to occur of (a) September 29, 2022 and (b) the date upon which a specific sale of borrowing base assets and a related prepayment of outstanding debt thereunder occurs, upon the occurrence of which the uncommitted maximum facility amount will return to $475.0 million. See "—Liquidity and Capital Resources—Financing Arrangements—Warehouse and Other Debt Financings" below.

In June 2022, one of our subsidiaries issued $317.0 million in aggregate principal amount of Series 2022-1 Class A solar asset-backed notes and $38.0 million in aggregate principal amount of Series 2022-1 Class B solar asset-backed notes (collectively, the "SOLIV Notes") with a maturity date of April 2057. The SOLIV Notes bear interest at an annual rate of 4.95% and 6.35% for the Class A and Class B notes, respectively. See "—Liquidity and Capital Resources—Financing Arrangements—Securitizations" below.

Securitizations

As a source of long-term financing, we securitize qualifying solar energy systems, energy storage systems and related solar service agreements into special purpose entities who issue solar asset-backed and solar loan-backed notes to institutional investors. We also securitize the cash flows generated by the membership interests in certain of our indirect, wholly-owned subsidiaries that are the managing member of a tax equity fund that owns a pool of solar energy systems, energy storage systems and related solar service agreements that were originated by one of our wholly-owned subsidiaries. The federal government currently provides business investment tax credits under Section 48(a) (the "Section 48(a) ITC") and residential energy credits under Section 25D (the "Section 25D Credit") of the U.S. Internal Revenue Code of 1986, as amended. We do not securitize the Section 48(a) ITC incentives associated with the solar energy systems and energy storage systems as part of these arrangements. We use the cash flows these solar energy systems and energy storage systems generate to service the monthly, quarterly or semi-annual principal and interest payments on the notes and satisfy the expenses and reserve requirements of the special purpose entities, with any remaining cash distributed to their sole members, who are typically our indirect wholly-owned subsidiaries. In connection with these securitizations, certain of our affiliates receive a fee for managing and servicing the solar energy systems and energy storage systems pursuant to management, servicing, facility administration and asset management agreements. The special purpose entities are also typically required to maintain a liquidity reserve account and a reserve account for equipment replacements and, in certain cases, reserve accounts for financing fund purchase option/withdrawal right exercises or storage system replacement for the benefit of the holders under the applicable series of notes, each of which are funded from initial deposits or cash flows to the levels specified therein. The creditors of these special purpose entities have no recourse to our other assets except as expressly set forth in the terms of the notes. From our inception through June 30, 2022, we have issued $3.2 billion in solar asset-backed and solar loan-backed notes.

Tax Equity Funds

Our ability to offer long-term solar service agreements depends in part on our ability to finance the installation of the solar energy systems and energy storage systems by co-investing with tax equity investors, such as large banks who value the resulting customer receivables and Section 48(a) ITCs, accelerated tax depreciation and other incentives related to the solar energy systems and energy storage systems, primarily through structured investments known as "tax equity". Tax equity investments are generally structured as non-recourse project financings known as "tax equity funds". In the context of distributed generation solar energy, tax equity investors make contributions upfront or in stages based on milestones in exchange for a share of the tax attributes and cash flows emanating from an underlying portfolio of solar energy systems and energy storage systems. In these tax equity funds, the U.S. federal tax attributes offset taxes that otherwise would have been payable on the investors' other operations. The terms and conditions of each tax equity fund vary significantly by investor and by fund. We continue to negotiate with potential investors to create additional tax equity funds.

In general, our tax equity funds are structured using the "partnership flip" structure. Under partnership flip structures, we and our tax equity investors contribute cash into a partnership. The partnership uses this cash to acquire long-term solar service agreements, solar energy systems and energy storage systems developed by us and sells energy from such solar energy systems and energy storage systems, as applicable, to customers or directly leases the solar energy systems and energy storage systems, as applicable, to customers. We assign these solar service agreements, solar energy systems, energy storage systems and related incentives to our tax equity funds in accordance with the criteria of the specific funds. Upon such assignment and the satisfaction of certain conditions precedent, we are able to draw down on the tax equity fund commitments. The conditions precedent to funding vary across our tax equity funds but generally require that we have entered into a solar service agreement with the customer, the customer meets certain credit criteria, the solar energy system is expected to be eligible for the Section 48(a) ITC, we have a recent appraisal from an independent appraiser establishing the fair market value of the solar energy

34

system and the property is in an approved state or territory. Certain tax equity investors agree to receive a minimum target rate of return, typically on an after-tax basis, which varies by tax equity fund. Prior to receiving a contractual rate of return or a date specified in the contractual arrangements, the tax equity investor receives substantially all of the non-cash value attributable to the solar energy systems and energy storage systems, which includes accelerated depreciation and Section 48(a) ITCs; however, we typically receive a majority of the cash distributions, which are typically paid quarterly. After the tax equity investor receives its contractual rate of return or after a specified date, we receive substantially all of the cash and tax allocations.

We have determined we are the primary beneficiary in these tax equity funds for accounting purposes. Accordingly, we consolidate the assets and liabilities and operating results of these partnerships in our consolidated financial statements. We recognize the tax equity investors' share of the net assets of the tax equity funds as redeemable noncontrolling interests and noncontrolling interests in our consolidated balance sheets. The income or loss allocations reflected in our consolidated statements of operations may create significant volatility in our reported results of operations, including potentially changing net loss attributable to stockholders to net income attributable to stockholders, or vice versa, from quarter to quarter.

We typically have an option to acquire, and our tax equity investors may have an option to withdraw and require us to purchase, all the equity interests our tax equity investor holds in the tax equity funds starting approximately five years after the last solar energy system in the applicable tax equity fund is operational. If we or our tax equity investors exercise this option, we are typically required to pay at least the fair market value of the tax equity investor's equity interest and, in certain cases, a contractual minimum amount. From our inception through June 30, 2022, we have received commitments of approximately $1.4 billion through the use of tax equity funds, of which an aggregate of $1.2 billion has been funded and $92.6 million remains available for use.

Key Financial and Operational Metrics

We regularly review a number of metrics, including the following key operational and financial metrics, to evaluate our business, measure our performance, identify trends affecting our business, formulate our financial projections and make strategic decisions.

Number of Customers. We define number of customers to include every unique premises on which a Sunnova product is installed or on which Sunnova is obligated to perform services for a counterparty. We track the total number of customers as an indicator of our historical growth and our rate of growth from period to period.

	As of   June 30, 2022	As of   December 31, 2021	Change
Number of customers	225,000	192,600	32,400

Weighted Average Number of Systems. We calculate the weighted average number of systems based on the number of months a customer and any additional service obligation related to a solar energy system is in-service during a given measurement period. The weighted average number of systems reflects the number of systems at the beginning of a period, plus the total number of new systems added in the period adjusted by a factor that accounts for the partial period nature of those new systems. For purposes of this calculation, we assume all new systems added during a month were added in the middle of that month. The number of systems for any end of period will exceed the number of customers, as defined above, for that same end of period as we are also including any additional services and/or contracts a customer or third party executed for the additional work for the same residence. We track the weighted average system count in order to accurately reflect the contribution of the appropriate number of systems to key financial metrics over the measurement period.

Weighted average number of systems	217,200	149,300	208,600	129,900

Adjusted EBITDA. We define Adjusted EBITDA as net income (loss) plus net interest expense, depreciation and amortization expense, income tax expense, financing deal costs, natural disaster losses and related charges, net, losses on

35

extinguishment of long-term debt, realized and unrealized gains and losses on fair value instruments, amortization of payments to dealers for exclusivity and other bonus arrangements, legal settlements and excluding the effect of certain non-recurring items we do not consider to be indicative of our ongoing operating performance such as, but not limited to, costs of our initial public offering ("IPO"), acquisition costs, losses on unenforceable contracts and other non-cash items such as non-cash compensation expense, asset retirement obligation ("ARO") accretion expense, provision for current expected credit losses and non-cash inventory impairments.

Adjusted EBITDA is a non-GAAP financial measure we use as a performance measure. We believe investors and securities analysts also use Adjusted EBITDA in evaluating our operating performance. This measurement is not recognized in accordance with accounting principles generally accepted in the United States of America ("GAAP") and should not be viewed as an alternative to GAAP measures of performance. The GAAP measure most directly comparable to Adjusted EBITDA is net income (loss). The presentation of Adjusted EBITDA should not be construed to suggest our future results will be unaffected by non-cash or non-recurring items. In addition, our calculation of Adjusted EBITDA is not necessarily comparable to Adjusted EBITDA as calculated by other companies.

We believe Adjusted EBITDA is useful to management, investors and analysts in providing a measure of core financial performance adjusted to allow for comparisons of results of operations across reporting periods on a consistent basis. These adjustments are intended to exclude items that are not indicative of the ongoing operating performance of the business. Adjusted EBITDA is also used by our management for internal planning purposes, including our consolidated operating budget, and by our board of directors in setting performance-based compensation targets. Adjusted EBITDA should not be considered an alternative to but viewed in conjunction with GAAP results, as we believe it provides a more complete understanding of ongoing business performance and trends than GAAP measures alone. Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP.

Interest Income and Principal Payments from Customer Notes Receivable. Under our loan agreements, the customer obtains financing for the purchase of a solar energy system from us and we agree to operate and maintain the solar energy system throughout the duration of the agreement. Pursuant to the terms of the loan agreement, the customer makes scheduled principal and interest payments to us and has the option to prepay principal at any time in part or in full. Whereas we typically recognize payments from customers under our leases and PPAs as revenue, we recognize payments received from customers under our loan agreements (a) as interest income, to the extent attributable to earned interest on the contract that financed the customer's purchase of the solar energy system; (b) as a reduction of a note receivable on the balance sheet, to the extent

36

attributable to a return of principal (whether scheduled or prepaid) on the contract that financed the customer's purchase of the solar energy system; and (c) as revenue, to the extent attributable to payments for operations and maintenance services provided by us.

While Adjusted EBITDA effectively captures the operating performance of our leases and PPAs, it only reflects the service portion of the operating performance under our loan agreements. We do not consider our types of solar service agreements differently when evaluating our operating performance. In order to present a measure of operating performance that provides comparability without regard to the different accounting treatment among our three types of solar service agreements, we consider interest income from customer notes receivable and principal proceeds from customer notes receivable, net of related revenue, as key performance metrics. We believe these two metrics provide a more meaningful and uniform method of analyzing our operating performance when viewed in light of our other key performance metrics across the three primary types of solar service agreements.

Interest income from customer notes receivable	$	13,100	$	7,862	$	23,932	$	14,959
Principal proceeds from customer notes receivable, net of related revenue	$	24,781	$	15,773	$	45,194	$	28,075

Adjusted Operating Expense. We define Adjusted Operating Expense as total operating expense less depreciation and amortization expense, financing deal costs, natural disaster losses and related charges, net, amortization of payments to dealers for exclusivity and other bonus arrangements, legal settlements, direct sales costs, cost of revenue related to cash sales, cost of revenue related to inventory sales, unrealized gains and losses on fair value instruments and excluding the effect of certain non-recurring items we do not consider to be indicative of our ongoing operating performance such as, but not limited to, costs of our IPO, acquisition costs, losses on unenforceable contracts and other non-cash items such as non-cash compensation expense, ARO accretion expense, provision for current expected credit losses and non-cash inventory impairments. Adjusted Operating Expense is a non-GAAP financial measure we use as a performance measure. We believe investors and securities analysts will also use Adjusted Operating Expense in evaluating our performance. This measurement is not recognized in accordance with GAAP and should not be viewed as an alternative to GAAP measures of performance. The GAAP measure most directly comparable to Adjusted Operating Expense is total operating expense. We believe Adjusted Operating Expense is a supplemental financial measure useful to management, analysts, investors, lenders and rating agencies as an indicator of the efficiency of our operations between reporting periods. Adjusted Operating Expense should not be considered an alternative to but viewed in conjunction with GAAP total operating expense, as we believe it provides a more complete understanding of our performance than GAAP measures alone. Adjusted Operating Expense has limitations as an analytical tool and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP, including total operating expense.

We use per system metrics, including Adjusted Operating Expense per weighted average system, as an additional way to evaluate our performance. Specifically, we consider the change in this metric from period to period as a way to evaluate our performance in the context of changes we experience in the overall customer base. While the Adjusted Operating Expense figure provides a valuable indicator of our overall performance, evaluating this metric on a per system basis allows for further nuanced understanding by management, investors and analysts of the financial impact of each additional system.

Estimated Gross Contracted Customer Value. We calculate estimated gross contracted customer value as defined below. We believe estimated gross contracted customer value can serve as a useful tool for investors and analysts in comparing the remaining value of our customer contracts to that of our peers.

Estimated gross contracted customer value as of a specific measurement date represents the sum of the present value of the remaining estimated future net cash flows we expect to receive from existing customers during the initial contract term of our leases and PPAs, which are typically 25 years in length, plus the present value of future net cash flows we expect to receive from the sale of related solar renewable energy certificates ("SREC"), either under existing contracts or in future sales, plus the cash flows we expect to receive from energy services programs such as grid services, plus the carrying value of outstanding customer loans on our balance sheet. From these aggregate estimated initial cash flows, we subtract the present value of estimated net cash distributions to redeemable noncontrolling interests and noncontrolling interests and estimated operating, maintenance and administrative expenses associated with the solar service agreements. These estimated future cash flows reflect the projected monthly customer payments over the life of our solar service agreements and depend on various factors including but not limited to solar service agreement type, contracted rates, expected sun hours and the projected production capacity of the solar equipment installed. For the purpose of calculating this metric, we discount all future cash flows at 4%.

The anticipated operating, maintenance and administrative expenses included in the calculation of estimated gross contracted customer value include, among other things, expenses related to accounting, reporting, audit, insurance, maintenance and repairs. In the aggregate, we estimate these expenses are $20 per kilowatt per year initially, with 2% annual increases for inflation, and an additional $81 per year non-escalating expense included for energy storage systems. We do not include maintenance and repair costs for inverters and similar equipment as those are largely covered by the applicable product and dealer warranties for the life of the product, but we do include additional cost for energy storage systems, which are only covered by a 10-year warranty. Expected distributions to tax equity investors vary among the different tax equity funds and are based on individual tax equity fund contract provisions.

Estimated gross contracted customer value is forecasted as of a specific date. It is forward-looking and we use judgment in developing the assumptions used to calculate it. Factors that could impact estimated gross contracted customer value include, but are not limited to, customer payment defaults, or declines in utility rates or early termination of a contract in certain circumstances, including prior to installation. The following table presents the calculation of estimated gross contracted customer value as of June 30, 2022 and December 31, 2021, calculated using a 4% discount rate.

Sensitivity Analysis. The calculation of estimated gross contracted customer value and associated operational metrics requires us to make a number of assumptions regarding future revenues and costs which may not prove accurate. Accordingly, we present below a sensitivity analysis with a range of assumptions. We consider a discount rate of 4% to be appropriate based on recent transactions that demonstrate a portfolio of residential solar service agreements is an asset class that can be securitized successfully on a long-term basis with a coupon of less than 4%. We also present these metrics with a discount rate of 4% based on industry practice. The appropriate discount rate for these estimates may change in the future due to the level of inflation, rising interest rates, our cost of capital and consumer demand for solar energy systems. In addition, the table below provides a range of estimated gross contracted customer value amounts if different cumulative customer loss rate assumptions were used. We are presenting this information for illustrative purposes only and as a comparison to information published by our peers.

Significant Factors and Trends Affecting Our Business

Our results of operations and our ability to grow our business over time could be impacted by a number of factors and trends that affect our industry generally, as well as new offerings of services and products we may acquire or seek to acquire in the future. Additionally, our business is concentrated in certain markets, putting us at risk of region-specific disruptions such as adverse economic, regulatory, political, weather and other conditions. See "Risk Factors" in our Annual Report on Form 10-K filed with the SEC on February 24, 2022.

Financing Availability. Our future growth depends, in significant part, on our ability to raise capital from third-party investors on competitive terms to help finance the origination of our solar energy systems under our solar service agreements. We have historically used debt, such as convertible senior notes, asset-backed and loan-backed securitizations and warehouse facilities, tax equity, preferred equity and other financing strategies to help fund our operations. From our inception through June 30, 2022, we have raised more than $9.8 billion in total capital commitments from equity, debt and tax equity investors. With respect to tax equity, there are a limited number of potential tax equity investors, and the competition for this investment capital is intense. The principal tax credit on which tax equity investors in our industry rely is the Section 48(a) ITC. Starting January 1, 2020, the amount for the Section 48(a) ITC was equal to 30% of the basis of eligible solar property that began construction before 2020 if placed in service before 2026. By statute, the Section 48(a) ITC percentage decreased to 26% for eligible solar property that began construction during 2020 or 2021 or begins construction in 2022, 22% if construction begins in 2023 and 10% if construction begins after 2023 or if the property is placed into service after 2025. This reduction in the Section 48(a) ITC will likely reduce our use of tax equity financing in the future unless the Section 48(a) ITC is increased or replaced. IRS guidance includes a safe harbor that may apply when a taxpayer (or in certain cases, a contractor) pays or incurs 5% or more of the costs of a solar energy system before the end of the applicable year (the "5% ITC Safe Harbor"), even though the solar energy system is not placed in service until after the end of that year. We expect substantially all the solar energy systems installed in 2022 to qualify for the 26% Section 48(a) ITC. Additionally, we may make further inventory purchases in 2022 and future periods to extend the availability of each period's applicable Section 48(a) ITC by satisfying the 5% ITC Safe Harbor. Our ability to raise capital from third-party investors is affected by general economic conditions, the state of the capital markets, inflation levels and concerns about our industry or business. Specifically, interest rates remain subject to volatility that may result from action taken by the Federal Reserve. Recent data have suggested inflationary pressures may be more durable than anticipated, which could result in interest rate increases and/or the tapering of quantitative easing policies enacted towards the outset of the COVID-19 pandemic sooner than previously expected.

Cost of Solar Energy Systems and Energy Storage Systems. Upward pressure on prices of solar energy systems and energy storage systems may occur due to growth in the solar industry, regulatory policy changes, tariffs and duties, inflationary

39

cost pressures and an increase in demand. As a result of these developments, we may pay higher prices on solar modules, which may make it less economical for us to serve certain markets. Attachment rates for energy storage systems have trended higher while the price to acquire has remained steady and increased slightly for some suppliers due to several market variables, including COVID-19, raw material shortages and freight prices, but this still remains a potential area of growth for us.

Energy Storage Systems. Our energy storage systems increase our customers' independence from the centralized utility and provide on-site backup power when there is a grid outage due to storms, wildfires, other natural disasters and general power failures caused by supply or transmission issues. In addition, at times it can be more economic to consume less energy from the grid or, alternatively, to export solar energy back to the grid. Recent technological advancements for energy storage systems allow the energy storage system to adapt to pricing and utility rate shifts by controlling the inflows and outflows of power, allowing customers to increase the value of their solar energy system plus energy storage system. The energy storage system charges during the day, making the energy it stores available to the home when needed. It also features software that can customize power usage for the individual customer, providing backup power, optimizing solar energy consumption versus grid consumption or preventing export to the grid as appropriate. The software is tailored based on utility regulation, economic indicators and grid conditions. The combination of energy control, increased energy resilience and independence from the grid is strong incentive for customers to adopt solar and energy storage. As energy storage systems and their related software features become more advanced, we expect to see increased adoption of energy storage systems.

Climate Change Action. As a result of increasing global awareness of and aversion to climate change impacts, we believe the renewable energy market in which we operate, and investment in climate solutions more broadly, will continue to grow as the impact of climate change increases. This trend, along with increasing commitments to reduce carbon emissions, is expected to result in increased demand for our products and services. Under the current presidential administration, the focus on cleaner energy sources and technology to decarbonize the U.S. economy continues to accelerate. The federal government's administration under President Joe Biden ("Biden administration") has taken immediate steps that we believe signify support for cleaner energy sources, including, but not limited to, rejoining the Paris Climate Accord, re-establishing a social price on carbon used in cost/benefit analysis for policy making and announcing a commitment to transition the U.S. economy to a net-zero carbon economy by 2050. We expect the Biden administration, combined with a closely divided Congress, to continue to take actions that are supportive of the renewable energy industry, such as incentivizing clean energy sources and supporting new investment in areas like renewables.

Government Regulations, Policies and Incentives. Our growth strategy depends in significant part on government policies and incentives that promote and support solar energy and enhance the economic viability of distributed residential solar. These policies and incentives come in various forms, including net metering, eligibility for accelerated depreciation such as the modified accelerated cost recovery system, SRECs, tax abatements, rebates, renewable targets, incentive programs and tax credits, particularly the Section 48(a) ITC and the Section 25D Credit. Policies requiring solar on new homes or new roofs, such as those enacted in California and New York City, also support the growth of distributed solar. The sale of SRECs has constituted a significant portion of our revenue historically. A change in the value of net metering credits or SRECs or changes in other policies or a loss or reduction in such incentives could decrease the attractiveness of distributed residential solar to us, our dealers and our customers in applicable markets, which could reduce our customer acquisition opportunities. Such a loss or reduction could also reduce our willingness to pursue certain customer acquisitions due to decreased revenue or income under our solar service agreements. Additionally, such a loss or reduction may also impact the terms of and availability of third-party financing. If any of these government regulations, policies or incentives are adversely amended, delayed, eliminated, reduced, retroactively changed or not extended beyond their current expiration dates or there is a negative impact from the recent federal law changes or proposals, our operating results and the demand for, and the economics of, distributed residential solar energy may decline, which could harm our business.

Components of Results of Operations

Revenue. We recognize revenue from contracts with customers as we satisfy our performance obligations at a transaction price reflecting an amount of consideration based upon an estimated rate of return, net of cash incentives. We express this rate of return as the solar rate per kilowatt hour ("kWh") in the customer contract. The amount of revenue we recognize does not equal customer cash payments because we satisfy performance obligations ahead of cash receipt or evenly as we provide continuous access on a stand-ready basis to the solar energy system. We reflect the differences between revenue recognition and cash payments received in accounts receivable, other assets or deferred revenue, as appropriate.

PPAs. We have determined solar service agreements under which customers purchase electricity from us should be accounted for as revenue from contracts with customers. We recognize revenue based upon the amount of electricity delivered as determined by remote monitoring equipment at solar rates specified under the contracts. The PPAs generally have a term of 20 or 25 years with an opportunity for customers to renew for up to an additional 10 years, via two five-year or one 10-year

40

renewal options.

Lease Agreements. We are the lessor under lease agreements for solar energy systems and energy storage systems, which we account for as revenue from contracts with customers. We recognize revenue on a straight-line basis over the contract term as we satisfy our obligation to provide continuous access to the solar energy system. The lease agreements generally have a term of 20 or 25 years with an opportunity for customers to renew for up to an additional 10 years, via two five-year or one 10-year renewal options.

We provide customers under our lease agreements a performance guarantee that each solar energy system will achieve a certain specified minimum solar energy production output. The specified minimum solar energy production output may not be achieved due to natural fluctuations in the weather or equipment failures from exposure and wear and tear outside of our control, among other factors. We determine the amount of guaranteed output based on a number of different factors, including (a) the specific site information relating to the tilt of the panels, azimuth (a horizontal angle measured clockwise in degrees from a reference direction) of the panels, size of the solar energy system and shading on site; (b) the calculated amount of available irradiance (amount of energy for a given flat surface facing a specific direction) based on historical average weather data and (c) the calculated amount of energy output of the solar energy system.

If the solar energy system does not produce the guaranteed production amount, we are required to provide a bill credit or refund a portion of the previously remitted customer payments, where the bill credit or repayment is calculated as the product of (a) the shortfall production amount and (b) the dollar amount (guaranteed rate) per kWh that is fixed throughout the term of the contract. These bill credits or remittances of a customer's payments, if needed, are payable in January following the end of the first three years of the solar energy system's placed in service date and then every annual period thereafter. See Note 14, Commitments and Contingencies, to our interim unaudited condensed consolidated financial statements ("interim financial statements") included elsewhere in this Quarterly Report on Form 10-Q.

Inventory Sales. Inventory sales revenue represents revenue from the direct sale of inventory to our dealers or other parties. We recognize the related revenue under ASC 606 upon shipment.

SRECs. Each SREC represents the environmental benefit of one megawatt hour (1,000 kWh) generated by a solar energy system. We sell SRECs to utilities and other third parties who use the SRECs to meet renewable portfolio standards and can do so separate from the actual electricity generated by the renewable-based generation source. We account for SRECs generated from solar energy systems owned by us, as opposed to those owned by our customers, as governmental incentives with no costs incurred to obtain them and do not consider those SRECs output of the underlying solar energy systems. We classify SRECs as inventory held until sold and delivered to third parties. We enter into economic hedges with major financial institutions related to expected production of SRECs through forward contracts to partially mitigate the risk of decreases in SREC market rates. While these fixed price forward contracts serve as an economic hedge against spot price fluctuations for the SRECs, the contracts do not qualify for hedge accounting and are not designated as cash flow hedges or fair value hedges. The contracts require us to physically deliver the SRECs upon settlement. We recognize the related revenue upon the transfer of the SRECs to the counterparty. The costs related to the sales of SRECs are generally limited to fees for brokered transactions. Accordingly, the sale of SRECs in a period generally has a favorable impact on our operating results for that period. In certain circumstances we are required to purchase SRECs on the open market to fulfill minimum delivery requirements under our forward contracts.

Cash Sales. Cash sales revenue represents revenue from a customer's purchase of a solar energy system from us typically when purchasing a new home. We recognize the related revenue upon verification of the home closing.

Loan Agreements. We recognize payments received from customers under loan agreements (a) as interest income, to the extent attributable to earned interest on the contract that financed the customer's purchase of the solar energy system; (b) as a reduction of a note receivable on the balance sheet, to the extent attributable to a return of principal (whether scheduled or prepaid) on the contract that financed the customer's purchase of the solar energy system; and (c) as revenue, to the extent attributable to payments for operations and maintenance services provided by us. Similar to our lease agreements, we provide customers under our loan agreements a performance guarantee that each solar energy system will achieve a certain specified minimum solar energy production output, which is a significant proportion of its expected output.

Other Revenue. Other revenue includes certain state and utility incentives, revenue from the direct sale of solar energy systems and energy storage systems to customers with financing provided by us and sales of service plans. We recognize revenue from state and utility incentives in the periods in which they are earned. We recognize revenue from the direct sale of energy storage systems in the period in which the storage components are placed in service. Service plans are available to customers whose solar energy system was not originally sold by Sunnova. We recognize revenue from service plan contracts on a straight-line basis over the life of the contract, which is typically 10 years.

Cost of Revenue—Depreciation. Cost of revenue—depreciation represents depreciation on solar energy systems under lease agreements and PPAs that have been placed in service.

Cost of Revenue—Inventory Sales. Cost of revenue—inventory sales represents costs related to the procurement and direct sale of inventory to our dealers or other parties, including shipping and handling costs.

Cost of Revenue—Other. Cost of revenue—other represents costs related to cash sales, costs to purchase SRECs on the open market, SREC broker fees and other items deemed to be a cost of providing the service of selling power to customers or potential customers, such as certain costs to service loan agreements, costs for filing under the Uniform Commercial Code to maintain title, title searches, credit checks on potential customers at the time of initial contract and other similar costs, typically directly related to the volume of customers and potential customers.

Operations and Maintenance Expense. Operations and maintenance expense represents costs from third parties for maintaining and servicing the solar energy systems, property insurance, property taxes and warranties. When services for maintaining and servicing solar energy systems are provided by Sunnova personnel rather than third parties, those amounts are included in payroll costs classified within general and administrative expense. During the six months ended June 30, 2022 and 2021, we incurred $8.3 million and $6.3 million, respectively, of Sunnova personnel costs related to maintaining and servicing solar energy systems, which are classified in general and administrative expense. In addition, operations and maintenance expense includes write downs and write-offs related to inventory adjustments, gains and losses on disposals and other impairments and impairments due to natural disaster losses net of insurance proceeds recovered under our business interruption and property damage insurance coverage for natural disasters.

General and Administrative Expense. General and administrative expense represents costs for our employees, such as salaries, bonuses, benefits and all other employee-related costs, including stock-based compensation, professional fees related to legal, accounting, human resources, finance and training, information technology and software services, marketing and communications, IPO costs, acquisition costs, travel and rent and other office-related expenses. General and administrative expense also includes depreciation on assets not classified as solar energy systems, including information technology software and development projects, vehicles, furniture, fixtures, computer equipment and leasehold improvements and accretion expense on AROs. We capitalize a portion of general and administrative costs, such as payroll-related costs, that is related to employees who are directly involved in the design, construction, installation and testing of the solar energy systems but not directly associated with a particular asset. We also capitalize a portion of general and administrative costs, such as payroll-related costs, that is related to employees who are directly associated with and devote time to internal information technology software and development projects, to the extent of the time spent directly on the application and development stage of such software project.

Other Operating Expense (Income). Other operating expense (income) primarily represents changes in the fair values of certain financial instruments related to our investments in solar receivables and contingent consideration.

Interest Expense, Net. Interest expense, net represents interest on our borrowings under our various debt facilities, amortization of debt discounts and deferred financing costs and realized and unrealized gains and losses on derivative instruments.

Interest Income. Interest income represents interest income from the notes receivable under our loan program and income on short term investments with financial institutions.

Loss on Extinguishment of Long-Term Debt, Net. Loss on extinguishment of long-term debt, net resulted from a make-whole payment related to the early repayment of one of our solar asset-backed notes.

Other Income. Other income primarily represents changes in the fair value of certain financial instruments related to non-operating assets.

Income Tax. We account for income taxes under Accounting Standards Codification 740, Income Taxes. As such, we determine deferred tax assets and liabilities based on temporary differences resulting from the different treatment of items for tax and financial reporting purposes. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. Additionally, we must assess the likelihood that deferred tax assets will be recovered as deductions from future taxable income. We have a full valuation allowance on our deferred tax assets because we believe it is more likely than not that our deferred tax assets will not be realized. We evaluate the recoverability of our deferred tax assets on a quarterly basis. The income tax expense includes the effects of taxes paid in U.S. territories where the tax code for the respective territory may have separate tax reporting

42

requirements, as applicable.

Net Income (Loss) Attributable to Redeemable Noncontrolling Interests and Noncontrolling Interests. Net income (loss) attributable to redeemable noncontrolling interests and noncontrolling interests represents tax equity interests in the net income or loss of certain consolidated subsidiaries based on hypothetical liquidation at book value.

Revenue increased by $80.5 million in the three months ended June 30, 2022 compared to the three months ended June 30, 2021 primarily as a result of inventory sales and an increased number of solar energy systems in service. The weighted

44

average number of systems (excluding systems with loan agreements, service-only agreements and cash sales) increased from approximately 95,600 for the three months ended June 30, 2021 to approximately 124,200 for the three months ended June 30, 2022. Excluding SREC revenue, revenue under our loan agreements, inventory sales revenue, cash sales revenue and service revenue, on a weighted average number of systems basis, revenue remained relatively flat at $475 per system for the three months ended June 30, 2021 compared to $457 per system for the same period in 2022 (4% decrease). Inventory sales revenue increased by $54.2 million in the three months ended June 30, 2022 compared to the three months ended June 30, 2021 due to the sale of inventory to our dealers or other parties, which began in April 2022. SREC revenue increased by $2.9 million in the three months ended June 30, 2022 compared to the three months ended June 30, 2021 primarily as a result of an increase in SREC prices in New Jersey. The fluctuations in SREC revenue from period to period are also affected by the total number of solar energy systems, weather seasonality and hedge and spot prices associated with the timing of the sale of SRECs. On a weighted average number of systems basis, revenues under our loan agreements increased from $69 per system for the three months ended June 30, 2021 to $83 per system for the same period in 2022 (21% increase) primarily due to (a) higher battery attachment rates and (b) increasing expected battery replacement costs, which are included in the loan, resulting in larger customer loan balances.

46

from approximately 24,300 for the three months ended June 30, 2021 to approximately 50,300 for the three months ended June 30, 2022. On a weighted average number of systems basis, loan interest income decreased from $324 per system for the three months ended June 30, 2021 to $260 per system for the three months ended June 30, 2022 primarily due to a decrease in the average annual interest rate for customer loans due to market conditions.

Loss on Extinguishment of Long-Term Debt, Net

Loss on extinguishment of long-term debt, net decreased by $9.8 million in the three months ended June 30, 2022 compared to the three months ended June 30, 2021 primarily due to a make-whole payment related to the early repayment of one of our solar asset-backed notes in June 2021.

Income Tax

We do not have income tax expense or benefit due to pre-tax losses and a full valuation allowance recorded for the three months ended June 30, 2022 and 2021. See "—Components of Results of Operations—Income Tax".

Net Income (Loss) Attributable to Redeemable Noncontrolling Interests and Noncontrolling Interests

Net income (loss) attributable to redeemable noncontrolling interests and noncontrolling interests changed by $30.2 million in the three months ended June 30, 2022 compared to the three months ended June 30, 2021 primarily due to an increase in income attributable to noncontrolling interests from tax equity funds added in 2020 and 2021.

acquisition of SunStreet. The weighted average number of systems (excluding systems with loan agreements, service-only agreements and cash sales) increased from approximately 92,500 for the six months ended June 30, 2021 to approximately 120,300 for the six months ended June 30, 2022. Excluding SREC revenue, revenue under our loan agreements, inventory sales revenue, cash sales revenue and service revenue, on a weighted average number of systems basis, revenue remained relatively flat at $859 per system for the six months ended June 30, 2021 compared to $836 per system for the same period in 2022 (3% decrease). Inventory sales revenue increased by $54.2 million in the six months ended June 30, 2022 compared to the six months ended June 30, 2021 due to the sale of inventory to our dealers or other parties, which began in April 2022. SREC revenue increased by $3.1 million in the six months ended June 30, 2022 compared to the six months ended June 30, 2021 primarily as a result of an increase in SREC prices in New Jersey, offset by decrease due to a forward sale that occurred in the fourth quarter of 2021. The amount of SREC revenue recognized in each period is also affected by the total number of solar energy systems, weather seasonality and hedge and spot prices associated with the timing of the sale of SRECs. On a weighted average number of systems basis, revenues under our loan agreements increased from $128 per system for the six months ended June 30, 2021 to $165 per system for the same period in 2022 (28% increase) primarily due to (a) higher battery attachment rates and (b) increasing expected battery replacement costs, which are included in the loan, resulting in larger customer loan balances.

Net income attributable to redeemable noncontrolling interests and noncontrolling interests increased by $34.2 million in the six months ended June 30, 2022 compared to the six months ended June 30, 2021 primarily due to an increase in income attributable to noncontrolling interests from tax equity funds added in 2020 and 2021.

As of June 30, 2022, we had total cash of $363.9 million, of which $208.1 million was unrestricted, and $277.7 million of available borrowing capacity under our various financing arrangements. We seek to maintain diversified and cost-effective funding sources to finance and maintain our operations, fund capital expenditures, including customer acquisitions, and satisfy obligations arising from our indebtedness, which may include reducing debt prior to scheduled maturities through debt repurchases, either in the open market or in privately negotiated transactions, through debt redemptions or tender offers, or through repayments of bank borrowings. For a discussion of cash requirements from contractual and other obligations, see Note 14, Commitments and Contingencies, to our interim financial statements included elsewhere in this Quarterly Report on Form 10-Q. Historically, our primary sources of liquidity have included non-recourse and recourse debt, investor asset-backed and loan-backed securitizations and cash generated from operations. Our business model requires substantial outside financing arrangements to grow the business and facilitate the deployment of additional solar energy systems. We will seek to raise additional required capital, including from new and existing tax equity investors, additional borrowings, securitizations and other potential debt and equity financing sources. We believe our cash and financing arrangements, as further described below, will be sufficient to meet our anticipated cash needs for at least the next twelve months. As of June 30, 2022, we were in compliance with all debt covenants under our financing arrangements.

Financing Arrangements

The following is an update to the description of our various financing arrangements. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Financing Arrangements" in our Annual Report on Form 10-K filed with the SEC on February 24, 2022 for a full description of our various financing arrangements.

Tax Equity Fund Commitments

As of June 30, 2022, we had undrawn committed capital of approximately $92.6 million under our tax equity funds, which may only be used to purchase and install solar energy systems. In February 2022, we admitted a tax equity investor with a total capital commitment of approximately $150.0 million. In May 2022, we admitted a tax equity investor with a total capital commitment of approximately $17.5 million.

Warehouse and Other Debt Financings

In June 2022, we amended a revolving credit facility to, among other things, (a) extend the scheduled commitment termination date to May 2024, (b) extend the facility maturity date to November 2024, (c) increase the aggregate commitment

51

amount from $200.0 million to $400.0 million, subject to reductions based on the outstanding principal balance of advances over certain time periods, (d) increase the maximum facility amount from $350.0 million to $475.0 million, (e) modify the interest rate on borrowings from accruing based on the London Inter-Bank Offered Rate ("LIBOR") to accruing based on a forward-looking term rate based on the secured overnight financing rate ("Term SOFR"), plus a Term SOFR spread adjustment, (f) add an amortization event relating to certain of our subsidiaries ceasing to originate solar loans (subject to certain thresholds, time periods and exceptions set forth therein), (g) add concentration limits for solar loans (1) with obligors with credit scores below certain thresholds and (2) for which the original principal balance exceeds a certain threshold and (h) modify eligibility requirements for solar loans to increase the permitted maximum original principal balance. In July 2022, we further amended this revolving credit facility to, among other things, increase the uncommitted maximum facility amount from $475.0 million to $535.0 million until the earlier to occur of (a) September 29, 2022 and (b) the date upon which a specific sale of borrowing base assets and a related prepayment of outstanding debt thereunder occurs, upon the occurrence of which the uncommitted maximum facility amount will return to $475.0 million. In June 2022, one of our subsidiaries used proceeds from the SOLIV Notes to repay $271.0 million in aggregate principal amount outstanding under their financing arrangement.

Securitizations

In February 2022, one of our subsidiaries issued $131.9 million in aggregate principal amount of Series 2022-A Class A solar loan-backed notes, $102.2 million in aggregate principal amount of Series 2022-A Class B solar loan-backed notes and $63.8 million in aggregate principal amount of Series 2022-A Class C solar loan-backed notes (collectively, the "HELVIII Notes") with a maturity date of February 2049. The HELVIII Notes bear interest at an annual rate of 2.79%, 3.13% and 3.53% for the Class A, Class B and Class C notes, respectively. In June 2022, one of our subsidiaries issued $317.0 million in aggregate principal amount of Series 2022-1 Class A solar asset-backed notes and $38.0 million in aggregate principal amount of Series 2022-1 Class B solar asset-backed notes with a maturity date of April 2057. The SOLIV Notes bear interest at an annual rate of 4.95% and 6.35% for the Class A and Class B notes, respectively.

Historical Cash Flows—Six Months Ended June 30, 2022 Compared to Six Months Ended June 30, 2021

The following table summarizes our cash flows for the periods indicated:

	Six Months Ended   June 30,
	2022		2021		Change
	(in thousands)
Net cash used in operating activities	$	(162,343)	$	(110,684)	$	(51,659)
Net cash used in investing activities	(893,992)		(509,189)		(384,803)
Net cash provided by financing activities	1,028,328		711,078		317,250
Net increase (decrease) in cash and restricted cash	$	(28,007)	$	91,205	$	(119,212)

Operating Activities

Net cash used in operating activities increased by $51.7 million in the six months ended June 30, 2022 compared to the six months ended June 30, 2021. This increase is primarily a result of increases in purchases of inventory and prepaid inventory of $28.3 million and payments to dealers for exclusivity and other bonus arrangements of $7.0 million. This increase is offset by an increase in net inflows of $13.9 million in 2022 compared to net outflows of $0.8 million in 2021 based on: (a) our net loss of $30.3 million in 2022 excluding non-cash operating items of $44.3 million, primarily from depreciation, impairments and losses on disposals, amortization of intangible assets, amortization of deferred financing costs and debt discounts, unrealized net gains on derivatives, unrealized net gains on fair value instruments and equity-based compensation charges, which results in net inflows of $13.9 million and (b) our net loss of $90.3 million in 2021 excluding non-cash operating items of $89.5 million, primarily from depreciation, impairments and losses on disposals, amortization of deferred financing costs and debt discounts, unrealized net gains on derivatives, unrealized net losses on fair value instruments and equity-based compensation charges, which results in net outflows of $0.8 million. These net differences between the two periods resulted in a net change in operating cash flows of $14.7 million in 2022 compared to 2021.

52

Investing Activities

Net cash used in investing activities increased by $384.8 million in the six months ended June 30, 2022 compared to the six months ended June 30, 2021. This increase is primarily a result of increases in payments for investments and customer notes receivable of $267.8 million and purchases of property and equipment, primarily solar energy systems, of $144.1 million. This increase is partially offset by increases in proceeds from customer notes receivable of $21.8 million and proceeds from investments in solar receivables of $5.6 million.

Financing Activities

Net cash provided by financing activities increased by $317.3 million in the six months ended June 30, 2022 compared to the six months ended June 30, 2021. This increase is primarily a result of increases in net borrowings under our debt facilities of $186.5 million and net contributions from our redeemable noncontrolling interests and noncontrolling interests of $54.6 million and the purchase of capped call transactions of $91.7 million in 2021.

Seasonality

The amount of electricity our solar energy systems produce is dependent in part on the amount of sunlight, or irradiation, where the assets are located. Because shorter daylight hours in winter months and poor weather conditions due to cloud cover, rain or snow results in less irradiation, the output of solar energy systems will vary depending on the season or the year. While we expect seasonal variability to occur, the geographic diversity in our assets helps to mitigate our aggregate seasonal variability.

Our Easy Plan PPAs with variable billing, Solar 20/20 Plan Agreements and Fixed Rate Power Purchase Agreements are subject to seasonality because we sell all the solar energy system's energy output to the customer at either a fixed price per kWh or indexed, variable rate per kWh. Our Easy Plan PPAs with balanced billing are not subject to seasonality (from a cash flow perspective or the customer's perspective) within a given year because the customer's payments are levelized on an annualized basis so we insulate the customer from monthly fluctuations in production. In addition, energy production true-ups and production estimate adjustments for Easy Plan PPAs with balanced billing are calculated over an entire year. However, our Easy Plan PPAs with balanced billing are subject to seasonality from a revenue recognition perspective because, similar to the Easy Plan PPAs with variable billing, we sell all the solar energy system's energy output to the customer. Our lease agreements are not subject to seasonality within a given year because we lease the solar energy system to the customer at a fixed monthly rate and the reference period for any production guarantee payments is a full year. Finally, our loan agreements are not subject to seasonality within a given year because the monthly installment payments for the financing of the customers' purchase of the solar energy system are fixed and the reference period for any production guarantee is a full year.

In addition, weather may impact our dealers' ability to install solar energy systems and energy storage systems. For example, the ability to install solar energy systems and energy storage systems during the winter months in the Northeastern U.S. is limited. This can impact the timing of when solar energy systems and energy storage systems can be installed and when we can acquire and begin to generate revenue from solar energy systems and energy storage systems.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our interim financial statements, which have been prepared in accordance with GAAP which requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, cash flows and related disclosures. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. In many instances, we could have reasonably used different accounting estimates, and in other instances, changes in the accounting estimates are reasonably likely to occur from period-to-period. Actual results may differ from these estimates. Our future financial statements will be affected to the extent our actual results materially differ from these estimates. For further information on our significant accounting policies, see Note 2, Significant Accounting Policies, in our Annual Report on Form 10-K filed with the SEC on February 24, 2022 and Note 2, Significant Accounting Policies, to our interim financial statements included elsewhere in this Quarterly Report on Form 10-Q.

We identify our most critical accounting policies as those that are the most pervasive and important to the portrayal of our financial position and results of operations, and that require the most difficult, subjective, and/or complex judgments by management regarding estimates about matters that are inherently uncertain. We believe the assumptions and estimates associated with our principles of consolidation, the valuation of assets acquired and liabilities assumed in acquisitions, the estimated useful life of our solar energy systems, the valuation of the removal assumptions, including costs, associated with

53

AROs, the valuation of redeemable noncontrolling interests and noncontrolling interests and our allowance for current expected credit losses have the greatest subjectivity and impact on our interim financial statements. Therefore, we consider these to be our critical accounting policies and estimates. There have been no material changes to our critical accounting policies and estimates as described in our Annual Report on Form 10-K.

Recent Accounting Pronouncements

See Note 2, Significant Accounting Policies, to our interim financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to various market risks in the ordinary course of our business. Market risk is the potential loss that may result from market changes associated with our business or with an existing or forecasted financial or commodity transaction. Our primary exposure includes changes in interest rates because certain borrowings bear interest at floating rates based on LIBOR, SOFR or a similar index plus a specified margin. We sometimes manage our interest rate exposure on floating-rate debt by entering into derivative instruments to hedge all or a portion of our interest rate exposure on certain debt facilities. We do not enter into any derivative instruments for trading or speculative purposes. Changes in economic conditions could result in higher interest rates, thereby increasing our interest expense and operating expenses and reducing funds available to capital investments, operations and other purposes. A hypothetical 10% increase in our interest rates on our variable-rate debt facilities would have increased our interest expense by $732,000 and $1.1 million for the three and six months ended June 30, 2022, respectively.

Item 4. Controls and Procedures.

Internal Control Over Financial Reporting

Evaluation of Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer ("CEO") and our Chief Financial Officer ("CFO"), of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q, pursuant to Rules 13a-15(e) and 15d-15(e) under the Exchange Act. In connection with that evaluation, our CEO and our CFO concluded our disclosure controls and procedures were effective and designed to provide reasonable assurance the information required to be disclosed is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms as of June 30, 2022, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosures. The term "disclosure controls and procedures", as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure information required to be disclosed by a company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure information required to be disclosed by a company in the reports it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Management recognizes any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Changes in Internal Control over Financial Reporting

In connection with the acquisition of SunStreet, we are integrating SunStreet's internal controls over financial reporting into our financial reporting framework. Such integration has resulted and may continue to result in changes that materially affect our internal control over financial reporting (as described in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Other than the changes that have and may continue to result from such integration, there was no change in our internal control over financial reporting that occurred during the second quarter of 2022 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

54

Limitations on Effectiveness of Controls and Procedures

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives as specified above. However, our management, including our principal executive and principal financial officers, does not expect that our disclosure controls and procedures will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within our company have been detected.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings.

Although we may, from time to time, be involved in litigation, claims and government proceedings arising in the ordinary course of business, we are not a party to any litigation or governmental or other proceeding we believe will have a material adverse impact on our financial position, results of operations or liquidity. In the ordinary course of business, we have disputes with dealers and customers. In general, litigation claims or regulatory proceedings can be expensive and time consuming to bring or defend against, may result in the diversion of management attention and resources from our business and business goals and could result in settlement or damages that could significantly affect financial results and the conduct of our business.

Item 1A. Risk Factors.

There have been no material changes in the risks facing us as described in our Annual Report on Form 10-K filed with the SEC on February 24, 2022.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

In February 2021, we entered into an Earnout Agreement (the "Earnout Agreement") in connection with the April 2021 SunStreet acquisition. Pursuant to the terms of the Earnout Agreement, we are required to issue a number of earnout shares to Lenx, LLC, a subsidiary of Lennar Corporation, ("Lenx") if we meet certain commercial milestones, including if (a) we place a certain number of solar systems into service and enter into qualifying customer agreements related to such solar system for annual periods over four years commencing on the closing date of the acquisition and (b) prior to the fifth anniversary of the closing date of the acquisition, certain legally binding agreements relating to the development of microgrid communities are entered into. In April 2022, we issued 694,446 shares of common stock (the "Earnout Shares") to Lenx pursuant to the terms of the Earnout Agreement. The issuance of the Earnout Shares did not involve a public offering and was exempt from the registration requirements of the Securities Act pursuant to Section 4(a)(2) of the Securities Act, which exempts transactions by an issuer not involving any public offering.

Item 3. Defaults Upon Senior Securities.

Not applicable.

Item 4. Mine Safety Disclosures.

Not applicable.

Item 5. Other Information.

On July 22, 2022, a wholly-owned subsidiary (the "SLA Borrower") of Sunnova Energy International Inc. (the "Company") entered into that certain Amendment No. 9 to the Amended and Restated Credit Agreement (the "SLA Amendment"), which further amends that certain Amended and Restated Credit Agreement, dated as of March 27, 2019 (as previously amended, the "SLA Credit Agreement"), by and among the SLA Borrower, certain other subsidiaries of the Company, Credit Suisse AG, New York Branch, as agent, and the lenders and other financial institutions party thereto. The SLA Amendment amended the SLA Credit Agreement to, among other things, increase the uncommitted maximum facility amount from $475.0 million to $535.0 million until the earlier to occur of (a) September 29, 2022 and (b) the date upon which a specific sale of borrowing base assets and a related prepayment of outstanding debt thereunder occurs, upon the occurrence of which the uncommitted maximum facility amount will return to $475.0 million. The foregoing description of the SLA Amendment is qualified in its entirety by reference to the full text of the SLA Amendment, a copy of which is filed as Exhibit 10.4 to this Quarterly Report on Form 10-Q and is incorporated into this Item 5 by reference.
