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 10.1 to this Current Report on Form 8-K (this “report”) and is incorporated into this Item 1.01 by reference.

Solar Asset Securitization

On December 19, 2024, a wholly owned, indirect subsidiary (“Aurora I Issuer”) of the Company, entered into an indenture (the “Indenture”) with Wilmington Trust, National Association, as the indenture trustee, and completed an issuance of solar asset backed notes that were issued pursuant to the Indenture (the “Transaction”).

Aurora I Issuer issued $197,600,000 6.50% Solar Asset Backed Notes, Series 2024-PR1, Class A (the “Class A Notes”), and $17,900,000 6.70% Solar Asset Backed Notes, Series 2024-PR1, Class B (the “Class B Notes”) and $12,700,000 11.00% Solar Asset Backed Notes, Series 2024-PR1, Class C (the “Class C Notes” and, together with the Class A Notes and Class B Notes, the “Notes”). The Notes have an anticipated repayment date of January 30, 2030.

The Notes were offered within the United States only to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), to institutional accredited investors under Section 4(a)(2) of the Securities Act, and to persons outside of the United States in compliance with Regulation S under the Securities Act. The Notes have not been and will not be registered under the Securities Act or the securities laws of any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements under the Securities Act and other applicable securities laws. The Class A Notes, Class B Notes and Class C Notes have been rated AA (low) (sf), A (sf) and BB (sf) respectively, by Morningstar DBRS.

The Collateral

The Notes are secured by, and payable from the cash flow generated by, the membership interests in the Aurora I Issuer’s wholly owned, direct subsidiaries, and the sale of renewable energy credits. Each such subsidiary owns a managing member interest in a project company. Each project company owns a pool of photovoltaic systems, related lease agreements or power purchase agreements and other related solar assets. All but one project company is jointly owned with a third-party investor.

Sunnova TE Management, LLC, a Delaware limited liability company and a wholly owned, direct subsidiary of the Company (the “Transaction Manager”), will act as transaction manager pursuant to the terms of a Transaction Management Agreement between the Aurora I Issuer and the Transaction Manager. The Transaction Manager will be required to provide certain administrative, collection, and other management services to the Aurora I Issuer, including in respect of the subsidiaries of Aurora I Issuer and the renewable energy credits distributed to Aurora I Issuer by them.

Events of Default and Amortization Events

The Indenture contains events of default that are customary in nature for solar securitizations of this type, including, among other things, (a) the non-payment of interest, (b) material violations of covenants, (c) material breaches of representations and warranties and (d) certain bankruptcy events. An event of default will also occur with respect to the Notes if they are not paid in full at their rated final maturity. The Notes are also subject to amortization events that are customary in nature for solar securitizations of this type, including (a) the occurrence of an event of default, (b) a debt service coverage ratio

falling below certain levels, (c) failure to maintain insurance, (d) the aggregate expenses of the project companies rising above certain levels and (e) failure to repay the Notes in full by their anticipated repayment date. The occurrence of an amortization event or an event of default could result in accelerated amortization of the Notes, and the occurrence of an event of default could, in certain instances, result in the liquidation of the collateral securing the Notes. In connection with the Transaction, Sunnova Energy Corporation, a wholly owned, direct subsidiary of the Company, issued a performance guaranty covering (a) the performance of certain obligations of its affiliates who manage or service the project companies and the collateral securing the Notes, (b) the performance obligations of the Transaction Manager under the Transaction Manager Agreement and (c) the payment of certain expenses incurred by the Aurora I Issuer and the Indenture Trustee.

Use of Proceeds

The Company intends to use the proceeds from the sale of the Notes (i) for the payment of expenses related to the offering of the Notes, (ii) to repay a portion of one or more currently existing financing arrangements of the Company or any of its affiliates and (iii) to finance or refinance, in whole or in part, existing or new investments and expenditures by the Company and its subsidiaries related to capital investment, research, development, acquisition, manufacturing, distribution, maintenance and operation of solar energy and storage systems and enabling technologies for solar energy storage and optimization.

The foregoing description of the Indenture is qualified in its entirety by reference to the full text of the Indenture, a copy of which is filed as Exhibit 10.2 to this report and is incorporated into this Item 1.01 by reference.

Item 1.02. Termination of a Material Definitive Agreement.

On December 19, 2024, the previously disclosed Credit Agreement, dated as of September 30, 2020 (as previously amended, the “AP8 Facility”), by and among Sunnova Asset Portfolio 8, LLC, as the borrower (the “Borrower”), Sunnova SLA Management, LLC, as the manager and servicer, Sunnova Asset Portfolio 8 Holdings, LLC, as the seller of solar loans and solar assets, the lenders from time to time party thereto, the funding agents from time to time party thereto, Banco Popular de Puerto Rico, as agent for the lenders, and U.S. Bank, National Association, as custodian, was voluntarily terminated by the Borrower. The AP8 Facility contemplated the financing of solar loans and solar assets in Puerto Rico acquired by the Borrower with an aggregate commitment of $215,000,000.

At the time of termination, all outstanding obligations under the AP8 Facility in an aggregate amount of $213,658,119.64, including interest, accrued fees and expenses, were paid in full and all hedging agreements permitted by the AP8 Facility were settled.

This Indenture (as amended or supplemented from time to time, this "Indenture") is dated as of December 19, 2024 between Sunnova Aurora I Issuer, LLC, a limited liability company organized under the laws of the State of Delaware, as issuer (the "Issuer"), and Wilmington Trust, National Association, a national banking association, not in its individual capacity but solely in its capacity as indenture trustee (together with its successors and assigns in such capacity, the "Indenture Trustee").

All covenants and agreements made by the Issuer herein are for the benefit and security of the Holders of the Notes. The Issuer is entering into this Indenture, and the Indenture Trustee is accepting the trusts created hereby, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged.

Granting Clause

The Issuer hereby Grants to the Indenture Trustee, for the benefit of the Holders of the Notes, as their interests may appear, all of the rights, title, interest and benefits of the Issuer (if any) whether now existing or hereafter arising in and to: (i) the Managing Member Membership Interests; (ii) the Contribution Agreement, the Transaction Management Agreement, the Manager Transition Agreement, the Custodial Agreement, the Performance Guaranty, any Letter of Credit and all other Transaction Documents; (iii) amounts (including, but not limited to Managing Member Distributions, Host Customer Payments, Insurance Proceeds and Equity Cure Payments) deposited from time to time into the Collection Account, the Liquidity Reserve Account and the Supplemental Reserve Account and all Eligible Investments in each such account; (iv) the membership interests of the Tax Equity Investor Member in the related Project Company, if and when acquired by the related Managing Member through the exercise of a Purchase Option, the exercise of a Withdrawal Right or otherwise, and upon such acquisition, all assets of such Project Company, (v) the membership interests of each Managing Member in the related Project Company; (vi) proceeds of any and all of the foregoing including all proceeds of the conversion, voluntary or involuntary, of any of the foregoing into cash or other property and (vii) all other assets of the Issuer (collectively, the "Trust Estate").

Each Note shall be dated the date of its authentication. The terms of the Notes are set forth in Exhibit A-1, Exhibit A-2 and Exhibit A-3 and are part of the terms of this Indenture.

(a)    Global Notes. The Underwritten Notes are being offered and sold by the Issuer to the Initial Purchasers pursuant to the Note Purchase Agreement, the Placed Notes are being sold directly by the Issuer to Institutional Accredited Investors pursuant to the applicable Placed Note

3

[***] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

Purchase Agreement and the Retained Notes are being acquired by Sunnova Energy or one of its Affiliates.

Subject to Section 2.12, the Underwritten Notes offered and sold within the United States to QIBs in reliance on Rule 144A, the Placed Notes and the Retained Notes shall each be issued initially in the form of Rule 144A Global Notes, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Indenture Trustee, as custodian for the Securities Depository, and registered in the name of the Securities Depository or a nominee of the Securities Depository, duly executed by the Issuer and authenticated by the Indenture Trustee as hereinafter provided. The Outstanding Note Balance of the Rule 144A Global Notes may from time to time be increased or decreased by adjustments made on the records of the Indenture Trustee and the Securities Depository or its nominee as hereinafter provided. The Indenture Trustee shall not be liable for any error or omission by the Securities Depository in making such record adjustments and the records of the Indenture Trustee shall be controlling with regard to outstanding principal amount of Notes hereunder.

Subject to Section 2.13, Notes offered and sold outside of the United States in reliance on Regulation S under the Securities Act shall initially be issued in the form of a Regulation S Temporary Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Indenture Trustee, as custodian for the Securities Depository, and registered in the name of the Securities Depository or the nominee of the Securities Depository for the investors’ respective accounts at Euroclear Bank S.A./N.V. as operator of the Euroclear System ("Euroclear"), or Clearstream Banking société anonyme ("Clearstream"), duly executed by the Issuer and authenticated by the Indenture Trustee as hereinafter provided. Beneficial interests in the Regulation S Temporary Global Notes may be held only through Euroclear or Clearstream.

Within a reasonable period of time following the expiration of the "40-day distribution compliance period" (as defined in Regulation S), beneficial interests in the Regulation S Temporary Global Note shall be exchanged for beneficial interests in Regulation S Permanent Global Notes upon the receipt by the Indenture Trustee of (i) a written certificate from the Securities Depository, together with copies of certificates from Euroclear and Clearstream, certifying that they have received certification of non-United States beneficial ownership of 100% of the Outstanding Note Balance of the Regulation S Temporary Global Note (except to the extent of any beneficial owners thereof who acquired an interest therein pursuant to another exemption from registration under the Securities Act and who will take delivery of a beneficial ownership interest in a Rule 144A Global Note, all as contemplated by Section 2.08(a)(ii)), and (ii) an Officer's Certificate from the Issuer. The Regulation S Permanent Global Notes will be deposited with the Indenture Trustee, as custodian, and registered in the name of a nominee of the Securities Depository. Simultaneously with the authentication of the Regulation S Permanent Global Notes, the Indenture Trustee shall cancel the Regulation S Temporary Global Note. The Outstanding Note Balance of the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes may from time to time be increased or decreased by adjustments made on the records of the Indenture Trustee and the Securities Depository or its nominee, as the case

4

[***] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

may be, in connection with transfers of interest as hereinafter provided. The Indenture Trustee shall incur no liability for any error or omission of the Securities Depository in making such record adjustments and the records of the Indenture Trustee shall be controlling with regard to outstanding principal amount of Regulation S Global Notes hereunder.

Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and prepayments. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Indenture Trustee, or by the Note Registrar at the direction of the Indenture Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.08.

The provisions of the "Operating Procedures of the Euroclear System" and "Terms and Conditions Governing Use of Euroclear" and the "Management Regulations" and "Instructions to Participants" of Clearstream shall be applicable to interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes that are held by the members of, or participants in, the Securities Depository ("Agent Members") through Euroclear or Clearstream.

Except as set forth in Section 2.08, the Global Notes may be transferred, in whole and not in part, only to another nominee of the Securities Depository or to a successor of the Securities Depository or its nominee.

(b)    Book-Entry Provisions. This Section 2.02(b) shall apply only to the Global Notes deposited with or on behalf of the Securities Depository.

The Issuer shall execute and the Indenture Trustee shall, in accordance with this Section 2.02(b), authenticate and deliver one Global Note for each Class of Notes which (i) shall be registered in the name of the Securities Depository or the nominee of the Securities Depository and (ii) shall be delivered by the Indenture Trustee to the Securities Depository or pursuant to the Securities Depository’s instructions or held by the Indenture Trustee as custodian for the Securities Depository.

Agent Members shall have no rights either under this Indenture with respect to any Global Note held on their behalf by the Securities Depository or by the Indenture Trustee as custodian for the Securities Depository or under such Global Note, and the Securities Depository may be treated by the Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Indenture Trustee or any agent of the Issuer or the Indenture Trustee from giving effect to any written certification, proxy or other authorization furnished by the Securities Depository or impair, as between the Securities Depository and its Agent Members, the operation of customary practices of such Securities Depository governing the exercise of the rights of an owner of a beneficial interest in any Global Note.

5

[***] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

The Note Registrar and the Indenture Trustee shall be entitled to treat the Securities Depository for all purposes of this Indenture (including the payment of principal of and interest on the Notes and the giving of instructions or directions hereunder) as the sole Holder of the Notes, and shall have no obligation to the Note Owners.

The rights of Note Owners shall be exercised only through the Securities Depository and shall be limited to those established by law and agreements between such Note Owners and the Securities Depository and/or the Agent Members pursuant to the Note Depository Agreement. The initial Securities Depository will make book-entry transfers among the Agent Members and receive and transmit payments of principal of and interest on the Notes to such Agent Members with respect to such Global Notes.

Whenever this Indenture requires or permits actions to be taken based upon instructions or directions of Holders of Notes evidencing a specified percentage of the Outstanding amount of the Notes, the Securities Depository shall be deemed to represent such percentage only to the extent that it has received instructions to such effect from Note Owners and/or Agent Members owning or representing, respectively, such required percentage of the beneficial interest in the Notes and has delivered such instructions to the Indenture Trustee.

(c)    Definitive Notes. Except as provided in Sections 2.08 and 2.13, owners of beneficial interests in Global Notes will not be entitled to receive physical delivery of certificated definitive, fully registered Notes (the "Definitive Notes").

Section 2.03.Payment of Interest.

(a)    On each Payment Date, the Note Interest for a Class of Notes will be distributed to the registered Noteholders of such Class of Notes as of the related Record Date to the extent Available Funds are sufficient for such distribution in accordance with the Priority of Payments. Interest on the Notes with respect to any Payment Date will accrue at the applicable Note Rate based on the Interest Accrual Period.

(a)If the Outstanding Note Balance of any Class of Notes has not been paid in full on or before the Anticipated Repayment Date, additional interest (the "Post-ARD Additional Note Interest") will begin to accrue during each Interest Accrual Period on such Class of Notes thereafter at the related Post-ARD Additional Interest Rate. The Post-ARD Additional Note Interest, if any, for a Class of Notes will only be due and payable (i) after the Aggregate Outstanding Note Balance has been paid in full or (ii) on the Payment Date on which a Voluntary Prepayment of all outstanding Notes in full is being made. Prior to such time, the Post-ARD Additional Note Interest accruing on a Class of Notes will be deferred and added to any Post-ARD Additional Note Interest previously deferred and remaining unpaid ("Deferred Post-ARD Additional Note Interest"). Deferred Post-ARD Additional Note Interest will not bear interest.

Section 2.04.Payments to Noteholders.

6

[***] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

(a)     Principal payments and interest on a Class of Notes will be made on each Payment Date to the Noteholders of such Class of Notes as of the related Record Date pursuant to the Priority of Payments. The remaining Outstanding Note Balance of each Class of Notes, if any, shall be payable no later than the Rated Final Maturity. Noteholders shall, subject to the priorities and conditions set forth in the Priority of Payments, be entitled to receive payments of interest and principal on each Payment Date. Any payment of interest or principal payable with respect to the Notes on the applicable Payment Date shall be made to the Person in whose name such Note is registered as of the Record Date for such Payment Date in the manner provided in Section 5.09.

(b)All reductions in the principal balance of a Note (or one or more Predecessor Notes) effected by payments of principal made on any Payment Date shall be binding upon all Holders of such Note and of any Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, whether or not such payment is noted on such Note.

Section 2.05.Execution, Authentication, Delivery and Dating.

(a)     The Notes shall be executed by the Issuer. The signature of such Authorized Officer on the Notes may be manual or facsimile. Notes bearing the manual or facsimile signature of any individual who was, at the time of execution thereof, an Authorized Officer of the Issuer shall bind the Issuer, notwithstanding the fact that such individual ceased to hold such office prior to the authentication and delivery of such Notes or did not hold such office at the date of issuance of such Notes.

(b)On the Closing Date, the Issuer shall, and at any time and from time to time after the execution and delivery of this Indenture, the Issuer may deliver Notes executed by the Issuer to the Indenture Trustee for authentication, and the Indenture Trustee, upon receipt of the Notes and of an Issuer Order, shall authenticate and deliver such Notes; provided, however, that the Indenture Trustee shall not authenticate the Notes on the Closing Date unless and until it shall have received the documents listed in Section 2.12.

(c)Each Note authenticated and delivered by the Indenture Trustee to or upon an Issuer Order on or prior to the Closing Date shall be dated the Closing Date. All other Notes that are authenticated after the Closing Date for any other purpose under this Indenture shall be dated the date of their authentication.

(d)Notes issued upon transfer, exchange or replacement of other Notes shall be issued in authorized denominations reflecting the Outstanding Note Balance so transferred, exchanged or replaced, but shall represent only the Outstanding Note Balance so transferred, exchanged or replaced. In the event that any Note is divided into more than one Note in accordance with this Article II, such Outstanding Note Balance shall be divided among the Notes delivered in exchange therefor.

Without unreasonable delay, the Issuer will execute and deliver to the Indenture Trustee Definitive Notes (other than in the case of Notes in global form) and thereupon any or all temporary Notes (other than in the case of Notes in global form) may be surrendered in exchange therefor, at the Corporate Trust Office, and the Indenture Trustee shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Definitive Notes. Such exchange shall be made by the Issuer at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Definitive Notes authenticated and delivered hereunder.

Section 2.07.Registration, Registration of Transfer and Exchange.

(i)     The purchaser (A)(1) is a QIB, (2) is aware that the sale to it is being made in reliance on Rule 144A and (3) is acquiring the Notes or interests therein for its own account (and not for the account of others) or as a fiduciary agent for others (which others are also QIBs and have executed an agreement containing substantially the same representations as provided herein), or (B) is not a U.S. Person and is purchasing the Notes or interests therein in an offshore transaction pursuant to Regulation S and, with respect to the Class C Notes only, is a QIB; provided that a portion of one or more Classes of Notes may be sold to Institutional Accredited Investors or transferred to Sunnova Energy of an Affiliate thereof on the Closing Date. The purchaser is aware that it (or any account of a QIB for which it is purchasing) may be required to bear the economic risk of an investment in the Notes for an indefinite period, and it (or such account) is able to bear such risk for an indefinite period.

(ii)     The purchaser understands that the Notes and interests therein are being offered in a transaction not involving any public offering in the United States within the meaning of the Securities Act, that the Notes have not been and will not be registered under the Securities Act or any other applicable securities laws and that (A) if in the future it decides to offer, resell, pledge or otherwise transfer any of the Notes or any interests therein, such Notes (or the interests therein) may not be offered, resold, pledged or otherwise transferred in denominations less than the applicable Minimum Denomination, and in each case, in integral multiples of $1,000 in excess thereof, and only (1) in the United States to a person whom the seller reasonably believes is a QIB in a transaction meeting the requirements of Rule 144A (acting for its own account and not for the account of others, or as a fiduciary or agent for other QIBs to whom notice is given that the sale, pledge or transfer is being made in reliance on Rule 144A), (2) outside the United States in a transaction complying with the provisions of Regulation S under the Securities Act and with respect to the Class C Notes, to a person reasonably believed to be a QIB, or (3) pursuant to another exemption from registration under the Securities Act (if available and evidenced by an opinion of counsel acceptable to the Issuer and the Indenture Trustee), in each of cases (1) through (3) in accordance with any applicable securities laws of any state of the United States and any other applicable jurisdiction, and that (B) the purchaser will, and each subsequent holder is required to, notify any subsequent purchaser of such Notes or interests therein from it of the resale restrictions referred to above. Notwithstanding the foregoing restriction, any Note that has originally been properly issued in an amount no less than the applicable Minimum Denomination, or any interest therein, may be offered, resold, pledged or otherwise transferred in a denomination less than the applicable Minimum Denomination if such lesser denomination is solely a result of a reduction of principal due to payments made in accordance with this Indenture.

(iii)The purchaser acknowledges that none of the Sunnova Entities, the Indenture Trustee, the Initial Purchasers or the Placement Agent or any person representing the Sunnova Entities, the Indenture Trustee, the Initial Purchasers or the Placement Agent has made any representation to it with respect to the Sunnova Entities, or the sale of any Notes, other than the information contained in the Offering Circular, which Offering Circular has been delivered to it and upon which it is relying in making its investment decision with respect to the Notes; accordingly, it acknowledges that no representation or warranty is made by the Sunnova Entities, the Indenture Trustee, the Initial Purchasers or the Placement Agent as to the accuracy or completeness of such materials; and it has had access to such financial and other information concerning the Sunnova Entities and the Notes as it has deemed necessary in connection with its decision to purchase any of the Notes, including an opportunity to ask questions and request information from the Sunnova Entities, the Indenture Trustee, the Initial Purchasers and the Placement Agent.

(a)     The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Securities Depository, in accordance with this Indenture and the procedures of the Securities Depository therefor, which shall include restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Beneficial interests in a Global Note may be transferred to persons who take delivery thereof in the form of a beneficial interest in the same Global Note in accordance with the transfer restrictions set forth in the legends in subsections of Section 2.07(c), as applicable. Transfers of beneficial interests in the Global Notes to persons required or permitted to take delivery thereof in the form of an interest in another Global Note shall be permitted as follows:

If, at any time, an owner of a beneficial interest in a Rule 144A Global Note deposited with the Securities Depository (or the Indenture Trustee as custodian for the Securities Depository) wishes to transfer its interest in such Rule 144A Global Note to a person who is required or permitted to take delivery thereof in the form of an interest in a Regulation S Global Note, such owner shall, subject to compliance with the applicable procedures described herein (the "Applicable Procedures"), exchange or cause the exchange of such interest for an equivalent beneficial interest in a Regulation S Global Note as provided in this Section 2.08(a)(i). Upon receipt by the Indenture Trustee of (1) instructions given in accordance with the Applicable Procedures from an Agent Member directing the Indenture Trustee to credit or cause to be credited a beneficial interest in the Regulation S Global Note in an amount equal to the beneficial interest in the Rule 144A Global Note to be exchanged, (2) a written order given in accordance with the Applicable Procedures containing information regarding the participant account of the Securities Depository and the Euroclear or Clearstream account to be credited with such increase, and (3) a certificate in the form of Exhibit B-1 hereto given by the Note Owner of such beneficial interest stating that the transfer of such interest has been made in compliance with the transfer restrictions applicable to the Global Notes and pursuant to and in accordance with Rule 903 or Rule 904 of Regulation S, then the Indenture Trustee, as Note Registrar, shall instruct the Securities Depository to reduce or cause to be reduced the initial Outstanding Note Balance of the applicable Rule 144A Global Note and to increase or cause to be increased the initial Outstanding Note Balance of the applicable Regulation S Global Note by the initial principal amount of the beneficial interest in the Rule 144A Global Note to be exchanged, to credit or cause to be credited to the account of the person specified in such instructions a beneficial interest in the Regulation S Global Note equal to the reduction in the initial Outstanding Note Balance of the Rule 144A Global Note, and to debit, or cause to be debited, from the account of the person making such exchange or transfer the beneficial interest in the Rule 144A Global Note that is being exchanged or transferred.

(ii)Regulation S Global Note to Rule 144A Global Note. If, at any time an owner of a beneficial interest in a Regulation S Global Note deposited with the Securities Depository or with the Indenture Trustee as custodian for the Securities Depository wishes to transfer its interest in such Regulation S Global Note to a person who is required or permitted to take delivery thereof in the form of an interest in a Rule 144A Global Note, such owner shall, subject to the Applicable Procedures, exchange or cause the exchange of such interest for an equivalent beneficial interest in a Rule 144A Global Note as provided in this Section 2.08(a)(ii).

(i)to register the transfer of Definitive Notes in the form of other Definitive Notes; or

(ii)to exchange such Definitive Notes for an equal principal amount of Definitive Notes of other authorized denominations,

the Note Registrar shall register the transfer or make the exchange as requested; provided, however, that the Definitive Notes presented or surrendered for register of transfer or exchange shall be duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Note Registrar duly executed by such Holder or by his attorney, duly authorized in writing; and

16

[***] = Certain information has been excluded from this exhibit because it is both not material and would likely cause harm to the company if publicly disclosed.

(i)if such Definitive Note is being transferred to a QIB in accordance with Rule 144A or in an offshore transaction pursuant to Regulation S, a certification to that effect from such Holder (in the form attached as Exhibit B-3 hereto); or

(ii)if such Definitive Note is being transferred in reliance on any other exemption from the registration requirements of the Securities Act, a certification to that effect from such Holder (in the form attached as Exhibit B-3 hereto) and an Opinion of Counsel from such Holder or the transferee reasonably acceptable to the Issuer and to the Indenture Trustee to the effect that such transfer is in compliance with the Securities Act.

(c)     Restrictions on Transfer and Exchange of Global Notes. Notwithstanding any other provision of this Indenture, a Global Note may not be transferred except by the Securities Depository to a nominee of the Securities Depository or by a nominee of the Securities Depository to the Securities Depository or another nominee of the Securities Depository or by the Securities Depository or any such nominee to a successor Securities Depository or a nominee of such successor Securities Depository.

(d)    Initial Issuance of the Notes. The Initial Purchasers and (solely with respect to the Retained Notes) Sunnova Energy or any of its Affiliates shall not be required to deliver, and neither the Issuer nor the Indenture Trustee shall demand therefrom, any of the certifications or opinions described in this Section 2.08 (other than Section 2.08(e)) in connection with the initial issuance of the Notes and the delivery thereof by the Issuer (or by Sunnova Energy or any of its Affiliates to Sunnova Energy or any of its Affiliates).

(a)Transfer Restrictions for the Class C Notes. By its acceptance of an Ownership Interest in a Class C Note, each transferee shall be deemed to have represented and agreed as follows:

(i)Either (a) it is not and will not become, for U.S. federal income tax purposes, a partnership, S corporation, grantor trust or an entity that is disregarded as separate from any of the foregoing (each such entity a "flow-through entity") or (b) if it is or becomes a flow-through entity, then (1) none of the direct or indirect beneficial owners of any of the interests in such flow-through entity has or ever will have 50% or more of the value of its interest in such flow-through entity attributable to the beneficial interest of such flow-through entity in any Class C Note, other interest (direct or indirect) in the Issuer, or any interest created under the Indenture and (2) it is not and will not be a principal purpose of the arrangement involving the flow-through entity's beneficial interest in any Class C Note to permit any entity to satisfy the 100-partner limitation of Section 1.7704-1(h)(1)(ii) of the Treasury Regulations necessary for such entity not to be classified as a publicly traded partnership for U.S. federal income tax purposes.

(ii)It will not (a) acquire, sell, transfer, assign, participate, pledge or otherwise dispose of any of its interests in any Class C Note (or any

(iv)Its beneficial interest in any Class C Note is not and will not be in an amount that is less than the Class C Minimum Denomination (which for this purpose includes a lesser denomination if such denomination is solely a result of a reduction of principal due to payments made in accordance with the Indenture), and it does not and will not hold any beneficial interest in any Class C Note on behalf of any person whose beneficial interest in any Class C Note is in an amount that is less than the Class C Minimum Denomination. It will not sell, transfer, assign, participate, pledge or otherwise dispose of any beneficial interest in any Class C Note or enter into any financial instrument or contract the value of which is determined by reference in whole or in part to any Class C Note, in each case, if the effect of doing so would be that the beneficial interest of any person in any Class C Note would be in an amount that is less than the Class C Minimum Denomination.

(v)It will not enter into any financial instrument the payment on which, or the value of which, is determined in whole or in part by reference to an interest in any Class C Note (including the amount of payments on any Class C Note, the value of any Class C Note or any contract that otherwise is described in Section 1.7704-1(a)(2)(i)(B) of the Treasury Regulations).

The Indenture Trustee may adopt and employ, at the expense of the Issuer, any reasonable means of notification of such payment (including, but not limited to, mailing notice of such payment to Noteholders whose Notes have been called but have not been surrendered for prepayment or whose right to or interest in moneys due and payable but not claimed is determinable from the records of the Indenture Trustee, at the last address of record for each such Noteholder).

related Determination Date, Sunnova Energy may, in its sole and absolute discretion, make a payment to the Issuer (as an indirect cash equity capital contribution through the Depositor, to be immediately deposited into the Collection Account and be part of Available Funds) in an amount equal to the amount in cash that, if deemed added to the sum specified in clause (i)(A) of the definition of DSCR, would cause the DSCR to be greater than 1.25 (each such payment by Sunnova Energy, an "Equity Cure Payment").

(b)In the event that Sunnova Energy elects to make an Equity Cure Payment, Sunnova Energy shall notify the Issuer, the Indenture Trustee and the Transaction Manager of such election on or prior to the date that is not later than three Business Days prior to the related Determination Date.

(b)In the event that any withholding Tax is imposed on the Issuer's payment (or allocations of income) to a Noteholder, such withholding Tax shall reduce the amount otherwise distributable to the Noteholder in accordance with this Indenture.

The amount of any withholding Tax imposed with respect to a Noteholder shall be treated as cash distributed to such Noteholder at the time it is withheld by the Issuer or the Indenture Trustee (at the direction of the Transaction Manager or the Issuer) and remitted to the appropriate taxing authority. If there is a possibility that withholding Tax is payable with respect to a distribution (such as a distribution to a non-U.S. Noteholder), the Indenture Trustee may in its sole discretion withhold such amounts in accordance with this clause (b). In the event that a Noteholder wishes to apply for a refund of any such withholding Tax, the Indenture Trustee shall reasonably cooperate with such Noteholder in making such claim so long as such Noteholder agrees to reimburse the Indenture Trustee for any out-of-pocket expenses incurred.

(c)Each Noteholder and Note Owner, by its acceptance of its Note, will be deemed to have consented to the provisions of the Priority of Payments.

(d)For all Tax purposes, each Noteholder and each Note Owner, by its acceptance of a Note, will be deemed to have agreed to, and hereby instructs the Indenture Trustee to, treat the Notes as indebtedness.

(e)Each Noteholder and each Note Owner by its acceptance of a Note or an interest in a Note, will be deemed to have agreed to provide the Indenture Trustee or the Issuer, upon request, with the Noteholder Tax Identification Information and, to the extent FATCA Withholding Tax is applicable, the Noteholder FATCA Information. Each Noteholder and Note Owner shall update or replace its previously provided Noteholder Tax Identification Information and Noteholder FATCA Information promptly if requested by the Indenture Trustee; provided that nothing herein shall require the Indenture Trustee to make such request. In addition, each Noteholder and each Note Owner will be deemed to agree that the Indenture Trustee has the right to withhold from any amount of interest or other amounts (without any corresponding gross-up) payable to a Noteholder or Note Owner that fails to comply with the foregoing requirements. The Issuer hereby covenants with the Indenture Trustee that the Issuer will cooperate with the Indenture Trustee in obtaining sufficient information so as to enable the Indenture Trustee to (i) determine whether or not the Indenture Trustee is obliged to make any withholding, including FATCA Withholding Tax, in respect of any payments with respect to a Note and (ii) to effectuate any such withholding. The parties agree that the Indenture Trustee shall be released of any liability arising from properly complying with this Section 5.09 and FATCA. The Issuer agrees to provide to the Indenture Trustee copies of any Noteholder Tax Identification Information and any Noteholder FATCA Information received by the Issuer from any Noteholder or Note Owner.

The Issuer shall cause the Transaction Manager, at the Transaction Manager’s expense, to cause a firm of Independent Accountants to prepare any Tax Returns required to be filed by the Issuer. The Indenture Trustee, upon reasonable written request, shall furnish the Issuer with all such information in the possession of the Indenture Trustee as may be reasonably required in connection with the preparation of any Tax Return of the Issuer.

Section 5.11.Reports by Indenture Trustee. Within five Business Days after the end of each Collection Period, the Indenture Trustee shall provide or make available electronically (or upon written request, by first class mail or facsimile) to the Transaction Manager a written report (electronic means shall be sufficient) setting forth the amounts in the Collection Account, the Liquidity Reserve Account and the Supplemental Reserve Account, and the identity of the investments included therein, as applicable. Without limiting the generality of the foregoing, the Indenture Trustee shall, upon the written request of the Transaction Manager, promptly transmit or make available electronically to the Transaction Manager, copies of all accountings of, and information with respect to, the Collection Account, the Liquidity Reserve Account and the Supplemental Reserve Account, investments thereof, as applicable, and payments thereto and therefrom.

(e)    no direction inconsistent with such written request has been given to the Indenture Trustee during such 30-day period by the Majority Noteholders of the Controlling Class;

it being understood and intended that no one or more Holders of Notes shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders of Notes, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided.

Section 9.08.Restoration of Rights and Remedies.

The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 9.10.Delay or Omission; Not Waiver. No delay or omission of the Indenture Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default

or any acquiescence therein. Every right and remedy given by this Article IX or by law to the Indenture Trustee or to the Noteholders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture Trustee or by the Noteholders, as the case may be.

Section 9.11.Control by Noteholders. Other than as set forth herein, the Majority Noteholders of the Controlling Class shall have the right to direct the time, method and place of conducting any Proceeding for any remedy available to the Indenture Trustee or exercising any trust or power conferred on the Indenture Trustee; provided that:

(b)    the Indenture Trustee may take any other action deemed proper by the Indenture Trustee which is not inconsistent with such direction; provided, however, that, subject to Section 7.01, the Indenture Trustee need not take any action which a Responsible Officer or Officers of the Indenture Trustee in good faith determines might involve it in liability (unless the Indenture Trustee is furnished with the reasonable indemnity referred to in Section 9.11(c)); and

(c)    the Indenture Trustee has been furnished reasonable indemnity against costs, expenses and liabilities which it might incur in connection therewith.

Section 9.12.Waiver of Certain Events by Less Than All Noteholders. The Super-Majority Noteholders of the Controlling Class may, on behalf of the Holders of all the Notes, waive any past Default, Event of Default or Transaction Manager Termination Event, and its consequences, except:

(a)    a Default in the payment of the principal of or interest on any Note, or a Default caused by the Issuer becoming subject to registration as an "investment company" under the 1940 Act, or

(b)    with respect to a covenant or provision hereof which under Article X cannot be modified or amended without the consent of the Holder of each Outstanding Note affected.

Upon any such waiver, such Default, Event of Default or Transaction Manager Termination Event shall cease to exist, and any Default, Event of Default or Transaction Manager Termination Event or other consequence arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default, Event of Default or Transaction Manager Termination Event or impair any right consequent thereon.

Section 9.13.Undertaking for Costs. All parties to this Indenture agree, and each Noteholder and each Note Owner by its acceptance of a Note, shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Indenture Trustee for any action taken, suffered or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to

79

the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 9.13 shall not apply to any suit instituted by the Indenture Trustee or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or interest on any Note on or after the Rated Final Maturity expressed in such Note.

Section 9.14.Waiver of Stay or Extension Laws. The Issuer covenants (to the extent that it may lawfully do so) that it will not, at any time, insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 9.15.Sale of Trust Estate.

(a)     The power to effect any sale of any portion of the Trust Estate pursuant to this Article IX shall not be exhausted by any one or more sales as to any portion of the Trust Estate remaining unsold, but shall continue unimpaired until the entire Trust Estate securing the Notes shall have been sold or all amounts payable on the Notes and under this Indenture with respect thereto shall have been paid. The Indenture Trustee, acting on its own or through an agent, may from time to time postpone any sale by public announcement made at the time and place of such sale.

(b)The Indenture Trustee shall not, in any private sale, sell to a third party the Trust Estate, or any portion thereof unless the Super-Majority Noteholders of the Controlling Class direct the Indenture Trustee, in writing, to make such sale or unless either (i) the proceeds of such sale or liquidation are sufficient to discharge in full the amounts then due and unpaid upon the Notes for principal and accrued interest and the fees and all other amounts required to be paid pursuant the Priority of Payments or (ii) the Holders of 100% of the principal amount of each Class of Notes then Outstanding consent thereto. Notwithstanding the foregoing, prior to the consummation of any sale of the Trust Estate (either private or public), the Indenture Trustee shall first offer the Originator the opportunity to purchase the Trust Estate for a purchase price equal to the greater of (x) the fair market value of the Trust Estate and (y) the aggregate outstanding note balance of the Notes, plus accrued interest thereon and fees owed thereto (such right, the "Right of First Refusal"). If the Originator does not exercise its Right of First Refusal within two Business Days of receipt thereof, then the Indenture Trustee shall sell the Trust Estate as otherwise set forth in this Section 9.15; provided, further, that if the Originator does not exercise its Right of First Refusal and the Indenture Trustee elects to sell the Trust Estate in a private sale to a third party, then prior to the sale thereof, the Indenture Trustee shall offer the Originator the opportunity to purchase the Trust Estate for the purchase price being offered by such third party, and the Originator shall have two Business Days to accept such offer.

(c)The Indenture Trustee or any Noteholder may bid for and acquire any portion of the Trust Estate in connection with a public or private sale thereof, and in lieu of paying cash therefor, any Noteholder may make settlement for the purchase price by crediting against amounts owing on the Notes of such Holder or other amounts owing to such Holder secured by

this Indenture, that portion of the net proceeds of such sale to which such Holder would be entitled, after deducting the reasonable costs, charges and expenses incurred by the Indenture Trustee or the Noteholders in connection with such sale. The Notes need not be produced in order to complete any such sale, or in order for the net proceeds of such sale to be credited against the Notes. The Indenture Trustee or the Noteholders may hold, lease, operate, manage or otherwise deal with any property so acquired in any manner permitted by law.

(d)The Indenture Trustee shall execute and deliver an appropriate instrument of conveyance transferring its interest in any portion of the Trust Estate in connection with a sale thereof. In addition, the Indenture Trustee is hereby irrevocably appointed the agent and attorney-in-fact of the Issuer to transfer and convey its interest in any portion of the Trust Estate in connection with a sale thereof, pursuant to this Section 9.15, and to take all action necessary to effect such sale. No purchaser or transferee at such a sale shall be bound to ascertain the Indenture Trustee’s authority, inquire into the satisfaction of any conditions precedent or see to the application of any monies.

(e)The method, manner, time, place and terms of any sale of all or any portion of the Trust Estate shall be commercially reasonable.

(f)This Section 9.15 is subject to Section 7.01(i).

Section 9.16.Action on Notes. The Indenture Trustee’s right to seek and recover judgment on the Notes or under this Indenture shall not be affected by the seeking, obtaining or application of any other relief under or with respect to this Indenture. Neither the Lien of this Indenture nor any rights or remedies of the Indenture Trustee or the Noteholders shall be impaired by the recovery of any judgment by the Indenture Trustee against the Issuer or by the levy of any execution under such judgment upon any portion of the Trust Estate or upon any of the assets of the Issuer.

specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or Opinion of Counsel need be furnished.

Section 12.02.Form of Documents Delivered to Indenture Trustee.

(a)     If several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

(b)Any certificate or opinion of an Authorized Officer of the Issuer may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by outside counsel, unless such Authorized Officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or opinion or any Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an Authorized Officer of any relevant Person, describing that the information with respect to such factual matters is in the possession of such Person, unless such officer or counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous. Any Opinion of Counsel may be based on the written opinion of other counsel, in which event such Opinion of Counsel shall be accompanied by a copy of such other counsel’s opinion and shall include a statement to the effect that such counsel believes that such counsel and the Indenture Trustee may reasonably rely upon the opinion of such other counsel.

(c)Where any Person is required to make, give or execute two or more applications, requests, consents, notices, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Noteholders signing such instrument or instruments.

In any case where a notice or report to Noteholders is mailed in the manner provided above, neither the failure to mail such notice or report, nor any defect in any notice or report so mailed, to any particular Noteholder shall affect the sufficiency of such notice or report with respect to other Noteholders, and any notice or report which is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided.

The Indenture Trustee will make no representation or warranties as to the accuracy or completeness of such documents and will assume no responsibility therefor. The Indenture Trustee’s internet website will initially be located at www.wilmingtontrustconnect.com or at such other address as the Indenture Trustee shall notify the parties to the Indenture from time to time.
