THIS INDENTURE (as amended or supplemented from time to time, this “Indenture”) is dated as of February 13, 2024 between Sunnova SOL VI 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”).

PRELIMINARY STATEMENT

Pursuant to this Indenture, there is hereby duly authorized the execution and delivery of three classes of notes designated as the Issuer’s 5.65% Solar Asset Backed Notes, Series 2024-1, Class A (the “Class A Notes”), the Issuer’s 7.00% Solar Asset Backed Notes, Series 2024-1, Class B (the “Class B Notes”), the Issuer’s 9.00% Solar Asset Backed Notes, Series 2024-1, Class C (the “Class C Notes” and together with the Class A Notes and the Class B Notes, the “Notes”). 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.

[***] = Certain information has been excluded from this exhibit because it is both not material

(a) Global Notes. The Underwritten Notes are being offered and sold by the Issuer to the Initial Purchasers pursuant to the Note Purchase Agreement and the Placed Notes are being sold directly by the Issuer to certain institutional accredited investors (within the meaning of Rule 501(a)(1), (2), (3), (7) or (9) of the Securities Act) pursuant to the applicable Placed Note Purchase Agreement.

The Underwritten Notes offered and sold within the United States to QIBs in reliance on Rule 144A and the Placed 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.

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 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.

[***] = 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.

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.

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.

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 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.

(b) 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.

(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.

and would likely cause harm to the company if publicly disclosed.

(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.

(e) No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication, substantially in the form provided for herein, executed by the Indenture Trustee by the manual signature of a Responsible Officer of the Indenture Trustee, and such executed certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered.

[***] = 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.

Section 2.06. Temporary Notes. Except for the Notes maintained in book-entry form, temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Definitive Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Issuer. Every such temporary Note shall be executed by the Issuer and authenticated by the Indenture Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the Definitive Notes. 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.

(a) The Indenture Trustee (in such capacity, the “Note Registrar”) shall cause to be kept at its Corporate Trust Office a register (the “Note Register”), in which, subject to such reasonable regulations as it may prescribe, the Note Registrar shall provide for the registration of the Notes and the registration of transfers of such Notes. The Notes are intended to be obligations in registered form for purposes of Section 163(f), Section 871(h)(2) and Section 881(c)(2) of the Code.

(b) Each Person who has or who acquires any Ownership Interest in a Note shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the provisions of this Section 2.07 and Section 2.08.

(c) Each purchaser of Global Notes, other than the Initial Purchasers, by its acceptance thereof, will be deemed to have acknowledged, represented and agreed as follows:

(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 the Class B Notes and the Class C Notes may be initially sold to certain institutional accredited investor (within the meaning of Rule 501(a)(1), (2), (3), (7) or (9) of the Securities Act) 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

8

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 Structuring Agent or any person representing the Sunnova Entities, the Indenture Trustee, the Initial Purchasers or the Structuring 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 Structuring 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 Structuring Agent. It acknowledges that the delivery of the Offering Circular at any time does not imply that information herein is correct as of any time subsequent to this date.

(iv) The purchaser understands that the Notes will, until such Notes may be resold pursuant to Rule 144(b)(1) of the Securities Act, unless otherwise agreed by the Issuer and the holder thereof, bear a legend substantially to the following effect:

THIS NOTE (OR ITS PREDECESSOR) HAS NOT BEEN AND WILL NOT BE REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER THE SECURITIES OR BLUE SKY LAWS OF ANY STATE IN THE UNITED STATES OR ANY FOREIGN SECURITIES LAWS. NEITHER

Section 3.01. Performance of Obligations.

(a) The Issuer will not take any action or permit any action to be taken by others which would release any Person from any of such Person’s covenants or obligations in any Transaction Document or under any instrument or agreement included in the Trust Estate or that would result in the amendment, hypothecation, subordination, termination or discharge of, or impair the validity or effectiveness of, any such instrument or agreement, except as ordered by any bankruptcy or other court or as permitted by, or expressly provided in, this Indenture, the Transaction Documents or such other instrument or agreement.

(b) To the extent consistent with the Issuer Operating Agreement, the Issuer may contract with other Persons to assist it in performing its duties hereunder, and any performance of such duties shall be deemed to be action taken by the Issuer. To the extent that the Issuer contracts with other Persons which include or may include the furnishing of reports, notices or correspondence to the Indenture Trustee, the Issuer shall identify such Persons in a written notice to the Indenture Trustee.

(c) The Issuer shall and shall require that the Depositor, Sunnova Intermediate Holdings, Sunnova SOL VI Holdings and SOL VI Owner Managing Member characterize (i) (x) the transfer of the Conveyed Property by Sunnova Intermediate Holdings to Sunnova SOL VI Holdings, the transfer of the Conveyed Property by Sunnova SOL VI Holdings to the Depositor and the transfer of the Conveyed Property by the Depositor to the Issuer pursuant to the Managing Member Contribution Agreement and (y) the transfer of SOL VI Owner Conveyed Property from Sunnova Intermediate Holdings to SOL VI Owner Managing Member and from SOL VI Owner Managing Member to SOL VI Owner Project Company pursuant to the SOL VI Owner Contribution Agreement, in each case, as an absolute transfer for legal purposes, (ii) the Grant of the Trust Estate by the Issuer under this Indenture as a pledge for financial accounting purposes, and (iii) the Notes as indebtedness for U.S. federal income tax purposes and for financial accounting purposes (unless otherwise required by Applicable Law). In this regard, the financial statements of SEI and its consolidated subsidiaries will show the Conveyed Property and SOL VI Owner Conveyed Property as owned by the consolidated group and the Notes as indebtedness of the consolidated group (and will contain appropriate footnotes stating that the assets of the Issuer will not be available to creditors of SEI, Sunnova Energy, Sunnova Intermediate Holdings, Sunnova SOL VI Holdings or the Depositor or any other Person), and the U.S. federal income Tax Returns of SEI, Sunnova Energy and its consolidated subsidiaries that are regarded entities for U.S. federal income tax purposes will indicate that the Notes are indebtedness unless otherwise required by Applicable Law. The Issuer will cause Sunnova Energy, Sunnova Intermediate Holdings, Sunnova SOL VI Holdings and the Depositor to file all required Tax Returns and associated forms, reports, schedules and supplements thereto in a manner consistent with such characterizations unless otherwise required by Applicable Law.

(d) The Issuer covenants to pay, or cause to be paid, all Taxes or other similar charges levied by any governmental authority with regard to the Trust Estate, except to the extent that the validity or amount of such Taxes is contested in good faith, via appropriate Proceedings and with adequate reserves established and maintained therefor in accordance with GAAP.

Except as otherwise expressly provided therein, the Issuer shall not waive, amend, modify, supplement or terminate any Transaction Document or any provision thereof without the consent of the Indenture Trustee (acting at the direction of the Majority Noteholders of the Controlling Class).

(g) If an Event of Default or Transaction Manager Termination Event shall arise from the failure of the Transaction Manager to perform any of its duties or obligations under the Transaction Management Agreement, the Issuer shall take all reasonable steps available to it to remedy such failure, including appointing a Replacement Transaction Manager pursuant to the terms of the Transaction Management Agreement.

(h) The Issuer, or the Transaction Manager on behalf of the Issuer, shall supply to the Indenture Trustee, at the time and in the manner required by applicable Treasury Regulations, for further distribution to such persons, and to the extent required by applicable Treasury Regulations, information with respect to any original issue discount accruing on the Notes.

(c) (i) create, incur or suffer, or permit to be created or incurred or to exist any Lien on any of the Trust Estate or the assets of any Managing Member or Non-Tax Equity Project Company or (ii) permit the Lien created by this Indenture or any other Transaction Document not to constitute a valid first priority, perfected Lien on the Trust Estate or the assets of any Managing Member or Non-Tax Equity Project Company pledged to the Indenture Trustee under the Pledge and Security Agreement, in each case subject to Permitted Liens;

Section 3.03. Money for Note Payments.

(a) All payments with respect to any Notes which are to be made from amounts withdrawn from the Collection Account pursuant to the Priority of Payments shall be made on behalf of the Issuer by the Indenture Trustee, and no amounts so withdrawn from an Account for payments with respect to the Notes shall be paid over to the Issuer under any circumstances except as provided in this Section 3.03 and Article V.

(c) Any money held by the Indenture Trustee in trust for the payment of any amount distributable but unclaimed with respect to any Note shall be held in a non-interest bearing trust account, and if the same remains unclaimed for two years after such amount has become due to such Noteholder, such money shall be discharged from such trust and paid to the Issuer upon an Issuer Order without any further action by any Person; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof (but only to the extent of the amounts so paid to the Issuer), and all liability of the Indenture Trustee with respect to such trust money shall thereupon cease. 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).

For avoidance of doubt, Sunnova Energy shall not be permitted to make an Equity Cure Payment during an Early Amortization Period or a Sequential Interest Amortization Period.

Section 5.08. Early Amortization Period Payments and Sequential Interest Amortization Period Payments. Any distributions of principal made during an Early Amortization Period or a Sequential Interest Amortization Period will be allocated in the following manner to determine any unpaid amounts on future Payment Dates: first, to the Scheduled Note Principal Payment amount calculated for such Class of Notes for such Payment Date; and second, to the Unscheduled Note Principal Payment amount calculated for such Class of Notes for such Payment Date. Any principal payments made in excess of the amounts allocated to the Scheduled Note Principal Payment and Unscheduled Note Principal Payment for such Payment Date will be considered an additional paydown of principal.

Section 5.09. Note Payments.

(a) The Indenture Trustee shall pay from amounts on deposit in the Collection Account in accordance with the Quarterly Transaction Report and the Priority of Payments to each Noteholder of record as of the related Record Date either (i) by wire transfer, in immediately available funds to the account of such Noteholder at a bank or other entity having appropriate facilities therefor, if such Noteholder shall have provided to the Indenture Trustee appropriate written instructions at least five Business Days prior to the related Payment Date (which instructions may remain in effect for subsequent Payment Dates unless revoked by such Noteholder), or (ii) if not, by check mailed to such Noteholder at the address of such Noteholder appearing in the Note Register, the amounts to be paid to such Noteholder pursuant to such Noteholder’s Notes; provided, however that so long as the Notes are registered in the name of the Securities Depository such payments shall be made to the nominee thereof in immediately available funds.

(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 Indenture Trustee is hereby authorized and directed to retain from amounts otherwise distributable to the Noteholders sufficient funds for the payment of any withholding Tax that is legally owed by the Issuer as instructed by the Transaction Manager, in writing in a Quarterly Transaction Report (but such

authorization shall not prevent the Indenture Trustee from contesting at the expense of the applicable Noteholder any such withholding Tax in appropriate Proceedings, and withholding payment of such withholding Tax, if permitted by law, pending the outcome of such Proceedings). 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. Upon reasonable request from the Indenture Trustee, the Issuer will provide such additional information that it may have to assist the Indenture Trustee in making any withholdings or informational reports.

Section 5.10. Statements to Noteholders; Tax Returns. Within the time period required by Applicable Law after the end of each calendar year, the Issuer shall cause the Indenture Trustee to furnish to each Person who at any time during such calendar year was a Noteholder of record and received any payment thereon any information required by the Code to enable such Noteholders to prepare their U.S. federal and state income Tax Returns. The obligation of the Indenture Trustee set forth in this paragraph shall be deemed to have been satisfied to the extent that information shall be provided by the Indenture Trustee, in the form of Form 1099 or other comparable form, pursuant to any requirements of the Code.

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.

Section 5.12. Final Balances. On the Termination Date, all moneys remaining in all Accounts, shall be, subject to applicable escheatment laws, remitted to, or at the direction of, the Issuer and after the return of such funds (or disposition thereof pursuant to applicable escheatment laws), the Indenture Trustee will have no liability with respect to such funds, and Holders shall look solely only to the Issuer for such amounts.

(e) If the Issuer elects to rescind the Voluntary Prepayment, it must give written notice to the Indenture Trustee of such determination at least two Business Days prior to the Voluntary Prepayment Date. If a Voluntary Prepayment of the Notes has been rescinded pursuant to this Section 6.01(e), the Indenture Trustee shall provide notice of such rescission to the registered owner of each Note which had been subject to the rescinded redemption at the address shown on the Note Register maintained by the Note Registrar with copies to the Issuer, Sunnova Energy, the Depositor and the Rating Agency.

Failure to make such Notice of Prepayment available to any Noteholder, or any defect therein, shall not affect the validity of any Proceedings for the prepayment of other Notes.

(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 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.

precedent, if any, have been complied with, except that in the case of any such application or request as to which the furnishing of certificates and Opinions of Counsel are 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.

(d) Wherever in this Indenture, in connection with any application or certificate or report to the Indenture Trustee, it is provided that the Issuer or the Transaction Manager shall deliver any document as a condition of the granting of such application, or as evidence of the Issuer’s or the Transaction Manager’s compliance with any term hereof, it is intended that the truth and accuracy, at the time of the granting of such application or at the effective date of such notice or report (as the case may be), of the facts and opinions stated in such document shall in such case be conditions precedent to the right of the Issuer to have such application granted or to the sufficiency of such notice or report. The foregoing shall not, however, be construed to affect the Indenture Trustee’s right to rely upon the truth and accuracy of any statement or opinion contained in any such document as provided in Section 7.01(b)(ii).

Section 12.03. Acts of Noteholders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Noteholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Noteholders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Indenture Trustee, and, where it is hereby expressly required, to the Issuer. 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. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 7.01) conclusive in favor of the Indenture Trustee and the Issuer, if made in the manner provided in this Section 12.03.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Whenever such execution is by an officer of a corporation or a member of a limited liability company or a partnership on behalf of such corporation, limited liability company or partnership, such certificate or affidavit shall also constitute sufficient proof of his authority.

(c) The ownership of Notes shall be proved by the Note Register.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Notes shall bind the Holder of every Note issued upon the registration or transfer thereof or in exchange therefor or in lieu thereof, with respect to anything done, omitted or suffered to be done by the Indenture Trustee or the Issuer in reliance thereon, whether or not notation of such action is made upon such Notes.

Section 12.05. Notices and Reports to Noteholders; Waiver of Notices.

(a) Where this Indenture provides for notice to Noteholders of any event or the mailing of any report to the Noteholders, such notice or report shall be written and shall be sufficiently given (unless otherwise herein expressly provided) if mailed, first-class, postage-prepaid, to each Noteholder affected by such event or to whom such report is required to be mailed or sent via electronic mail, at the address or electronic mail address of such Noteholder as it appears on the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice or the mailing of such report. 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.

(b) Where this Indenture provides for notice in any manner, such notice may be waived in writing by any Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Noteholders shall be filed with the Indenture Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

(c) If, by reason of the suspension of regular mail service as a result of a strike, work stoppage or similar activity, it shall be impractical to mail notice of any event to the Noteholders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving of such notice.

(d) The Indenture Trustee shall, on or before each Payment Date, make available to each Noteholder each Quarterly Transaction Report and, unless directed to do so under any other provision of this Indenture or any other Transaction Document (in which case no request shall be necessary), a copy of all reports, financial statements and notices received by the Indenture Trustee pursuant to this Indenture and the other Transaction Documents, but only with the use of a password provided by the Indenture Trustee; provided, however, the Indenture Trustee shall have no obligation to provide such information described in this Section 12.05 until it has received the requisite information from the Issuer or the Transaction Manager. The Indenture Trustee will make no representation or warranties as to the accuracy or completeness of such documents and will assume no responsibility therefor.

Section 12.09. Effect of Headings and Table of Contents. The Section and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

Section 12.10. Successors and Assigns. All covenants and agreements in this Indenture by the Issuer and the Indenture Trustee shall bind their respective successors and assigns, whether so expressed or not.

Section 12.11. Separability; Entire Agreement. If any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. Furthermore, in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as part of this Indenture, a provision as similar in its terms and purpose to such illegal, invalid or unenforceable provision as may be possible and be legal, valid and enforceable. This Indenture reflects the entire agreement with respect to the matters covered by this Indenture and supersedes any prior agreements, commitments, drafts, communication, discussions and understandings, oral or written, with respect thereto.

Section 12.12. Benefits of Indenture. Nothing in this Indenture or in the Notes, expressed or implied, shall give to any Person, other than the parties hereto and their successors hereunder, any separate trustee or co-trustee appointed under Section 7.13 and the Noteholders, any benefit or any legal or equitable right, remedy or claim under this Indenture.
