This Amendment No. 1 to Third Amended and Restated Credit Agreement (SLA) (this “Amendment”), is dated as of April 3, 2025 (the “Effective Date”), by and among Sunnova EZ-Own Portfolio, LLC, a Delaware limited liability company (the “Borrower”), Sunnova SLA Management, LLC, a Delaware limited liability company, as manager (in such capacity, the “Manager”) and as servicer (in such capacity, the “Servicer”), Sunnova Asset Portfolio 7 Holdings, LLC, a Delaware limited liability company, as seller (in such capacity, the “Seller”), the financial institutions parties hereto (each such financial institution (including any Conduit Lender), a “Lender” and, collectively, the “Lenders”), each Funding Agent representing a group of Lenders party hereto (each, a “Funding Agent” and, collectively, the “Funding Agents”), and Atlas Securitized Products Administration, L.P. (“Atlas”), as administrative agent under the Credit Agreement (as defined below) (in such capacity, the “Administrative Agent”). Except as otherwise defined in this Amendment, terms defined in the Credit Agreement are used herein as defined therein.

WHEREAS, the Borrower, the Manager, the Servicer, the Seller, the Lenders, the Funding Agents, the Administrative Agent, Computershare Trust Company, National Association, as paying agent, and U.S. Bank National Association, as custodian, are party to the Third Amended and Restated Credit Agreement, dated as of March 20, 2025 (as amended, amended and restated, supplemented, or otherwise modified from time to time prior to the date hereof, the “Credit Agreement”);

WHEREAS, the Borrower has requested certain amendments to the Credit Agreement as further described herein;

WHEREAS, the Borrower also acknowledges that a Borrowing Base Deficiency likely exists due to a violation of the eligibility criteria set forth in Schedule 1(A)(t) as to certain Solar Loans, which criteria requires payment of all unpaid fees owed to third parties relating to the origination of a related Solar Loan and installation of the related PV System once it is no longer a Substantial Stage Solar Loan or Final Stage Solar Loan (the “Dealer Payment Related Borrowing Base Deficiency”) and has requested a forbearance on exercise of remedies related to a Potential Default based on such Dealer Payment Related Borrowing Base Deficiency;

WHEREAS, in furtherance of the foregoing and in accordance with Section 10.2 of the Credit Agreement, the parties hereto desire to amend the Credit Agreement and grant a temporary forbearance subject to the terms and conditions set forth herein; and

NOW, THEREFORE, in consideration of the mutual promises hereinafter set forth, and for other good and adequate consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

Subject to the satisfaction of the conditions precedent set forth in Section 2.01 below, Section 6.1(R) of the Credit Agreement shall be, and it hereby is, amended as follows:

“(R)     Dealer Payments.     (i) Borrower (or Parent on its behalf) shall have failed to provide on or before the tenth (10th) Business Day following the Third Amendment and Restatement Date, to the Administrative Agent evidence satisfactory to it that the disbursements due by Parent (or its Affiliate) to the approved channel partners with respect to at least ninety percent (90%) of the aggregate Eligible Dealer Payments outstanding as of the Third Amendment and Restatement Date have been made and disbursed to such approved channel partners (as such date may be extended in consecutive increments of one (1) Business Day (each a “Deadline Extension”) in the Administrative Agent’s sole discretion, not to exceed a total of seven (7) Business Days beyond such initial date and so long as progress is being made on identification of the amounts due with respect to Borrower’s Solar Loans and arranging funding for such disbursements in its sole discretion), or (ii) Borrower (or Parent on its behalf) shall have failed to provide on or before the thirtieth (30th) calendar day following the Third Amendment and Restatement Date (or, if such thirtieth (30th) calendar day is not a Business Day, the next succeeding Business Day), to the Administrative Agent evidence satisfactory to it that the disbursements due by Parent (or its Affiliate) to the approved channel partners with respect to one hundred percent (100%) of the aggregate Eligible Dealer Payments outstanding as of the Third Amendment and Restatement Date have been made and disbursed to such approved channel partners. The Administrative Agent shall provide contemporaneous notice (by email) to the Lenders and Borrower of any Deadline Extension.”

The Administrative Agent and each Lender agree to forbear from exercising any remedies (whether at law or under the Credit Agreement) solely in respect of an Event of Default caused by any Dealer Payment Related Borrowing Base Deficiency on the Effective Date and to automatically extend such forbearance in consecutive increments of one (1) Business Day in connection with the granting of each Deadline Extension, if any, after the Effective Date. The Administrative Agent and each Lender further agree that once Borrower makes the Dealer Payments described in Section 6.01(R) and provides proof of payment thereof, the making of such Dealer Payments shall also be treated as curing any related ineligibility of a Solar Loan solely to the extent of the payments made and so long as no claim for damages related to non-payment of such Dealer Payments has been lodged against Borrower, provided that (i) any portion of the Dealer Payment Related Borrowing Base Deficiency not covered by such Dealer Payments shall continue to constitute a Borrowing Base Deficiency and (ii) the making of such Dealer Payments shall not be considered to cure any other ineligibility of Borrower’s Solar Loans such that any remaining Borrowing Base Deficiencies shall remain subject to Borrower’s

obligation to cure in accordance with the terms of the Credit Agreement and to all rights and remedies of the Administrative Agent and Lenders related to any failure to so cure.

The effectiveness of this Amendment is subject to the satisfaction of all of the following conditions precedent:

    (a)    The Administrative Agent, the Borrower, the Manager, the Servicer, the Seller, the Lenders party hereto and the Funding Agents party hereto shall have executed and delivered this Amendment to the Administrative Agent; and

(b)the execution, delivery and performance by it of this Amendment are within its powers, and do not conflict with, and will not result in a violation of, or constitute or give rise to a default under (i) any of its organizational documents, (ii) any agreement or other instrument which may be binding upon it, or (iii) any law, governmental regulation, court decree or order applicable to it or its properties, except, in each case, where such conflict, violation or default could not reasonably be expected to result in a Material Adverse Effect;

(c)it has all powers and all governmental licenses, authorizations, consents and approvals required to carry on its business as now conducted except where the failure to obtain such licenses, authorizations, consents and approvals would not result in a Material Adverse Effect; and
