Registration Statement on Form S-1

File No. 333-232393

Ladies and Gentlemen:

Pursuant to discussions with the staff of the Division of Corporation Finance (the “Staff”) of the Securities and Exchange Commission, Sunnova Energy International Inc. (the “Company”) hereby confidentially submits (the “Submission”) its currently expected offering terms of the initial public offering (the “Offering”) of its common stock, par value $0.0001 per share (the “Common Stock”), including, among other things, the bona fide price range pursuant to Item 501(b)(3) of Regulation S-K, the number of shares of Common Stock to be offered, the estimated net proceeds the Company expects to receive from the Offering and the total number of shares of Common Stock to be outstanding after the Offering. The Company expects that these pricing terms and other items will be included in a future amendment to the Registration Statement on Form S-1, File No. 333-232393 (the “Registration Statement”).

The Offering terms included in the Submission are based on bona fide estimates of the range of the minimum and maximum offering price and the maximum number of shares of Common Stock to be offered as of July 5, 2019. Should the bona fide estimates of these terms change, the figures presented in future amendments to the Registration Statement may increase or decrease.

The Company proposes to price the Offering with a bona fide price range of $15.00 to $18.00 per share, with a midpoint of $16.50 per share. In the Offering, the Company proposes to sell up to 18,181,818 shares of Common Stock. The Company also proposes to grant the underwriters a 30-day option to purchase up to an additional 2,727,273 shares of Common Stock to cover over-allotments. As discussed with members of the Staff, this range and the additional information included in the Submission are initially being provided for your consideration by correspondence due to the Company’s and the underwriters’ concern regarding providing such information in advance of the launch of the Offering given recent market volatility, as well as our desire to provide all information necessary for the Staff to complete its review on a timely basis.
