Sunnova Reviews (2026): Is It Still in Business?

What Happened: The June 2025 Chapter 11

Sunnova Energy International was, for most of its history, one of the largest residential solar-and-storage providers in the United States — a publicly traded company on the NYSE under the ticker NOVA, headquartered in Houston, with approximately 500,000 customer agreements spread across multiple states. The business model was primarily lease and power purchase agreement (PPA), with Sunnova owning the system on the customer's roof and selling the electricity back for a fixed monthly rate.

In June 2025, Sunnova filed for Chapter 11 bankruptcy protection. Revenue for FY2025 was approximately $839 million, but the company was carrying unsustainable debt levels relative to the cash generated by its customer portfolio. NEM 3.0's 75% cut to California export credits hit the whole sector, interest rate pressure through 2024 and 2025 made third-party-ownership economics thinner, and the balance-sheet math did not pencil out.

Through the bankruptcy process, substantially all of Sunnova's operating assets were sold to Solaris Assets, a vehicle backed by the company's bondholders. The sale closed and the ongoing portfolio, leases, PPAs, customer accounts, servicing operations. transitioned to a new operating company called SunStrong Management. The Sunnova brand name continues to be used for customer-facing communications, but the legal entity behind your contract, if you're a Sunnova customer, is no longer the pre-2025 Sunnova.

The bankruptcy, from the source documents

Sunnova Energy International Inc., along with affiliates Sunnova Energy Corporation and Sunnova Intermediate Holdings, LLC, filed for Chapter 11 protection on June 8, 2025, in the U.S. Bankruptcy Court for the Southern District of Texas (Houston Division), jointly administered under Case No. 25-90160 before Judge Alfredo R. Perez (Sunnova Energy International Inc., Case No. 25-90160, U.S. Bankruptcy Court, S.D. Tex., accessed via court docket September 22, 2026). A related developer entity, Sunnova TEP Developer, LLC, had already filed on June 1, 2025 (Case No. 25-90153).

Sunnova's own SEC filing made the same day confirms the company intended to “continue to operate their businesses and manage their properties as ‘debtors in possession’” during the case, and separately disclosed that it expected the New York Stock Exchange to move to delist its common stock — while noting that delisting “does not change its reporting requirements under the rules of the U.S. Securities and Exchange Commission” (Form 8-K, Item 1.03 and Item 3.01, filed 2025-06-09, accessed September 22, 2026). The filing also listed defaults triggered under four debt instruments — two bond indentures and two warehouse credit facilities — under Item 2.04.

The case closed out several months later: the court-approved plan's Effective Date was November 14, 2025, at which point the plan was formally consummated (case docket, via restructuring.ra.kroll.com/Sunnova, the case's official noticing agent, accessed September 22, 2026). That's the point at which the asset sale and the shift to SunStrong Management became final, not just proposed.

Utility records show the effect in California. Sunnova Energy Corporation (CSLB #1003498) is listed on 2,832 residential systems approved at PG&E, SCE and SDG&E in 2025, 94% of them leases or PPAs, but on 28 from January through May 2026 (California Distributed Generation Statistics, CPUC interconnection data through May 31, 2026, downloaded September 24, 2026).

What It Means for Existing Sunnova Customers

If your solar is already installed and producing, the short-term reality is similar to any residential solar owner: the panels keep producing, the inverter keeps inverting, and your utility keeps crediting exports under whichever NEM tariff you're on. That part doesn't depend on Sunnova or SunStrong.

What does depend on the new ownership is the 25-year performance guarantee, the lease or PPA payment administration, and post-install service (repairs, monitoring, billing disputes). The Chapter 11 plan provides that SunStrong honors the existing contract terms. Your monthly rate stays the same, your annual escalator stays the same, the 90% production guarantee persists. In practice, post-bankruptcy service response times have lengthened according to customer reports on BBB, Trustpilot and Reddit, as the new entity focuses on portfolio management rather than growth.

Manufacturer warranties on your panels, inverter, and battery are from the equipment makers themselves (not Sunnova) and are unaffected by the ownership change. Keep a copy of your original installation paperwork and the spec sheets for every component, if SunStrong service is slow on a warranty issue, you can sometimes pursue the manufacturer directly.

Practical steps for legacy Sunnova customers: confirm in writing (email is fine) that SunStrong is administering your specific contract. Keep paying your lease or PPA on schedule through the payment portal. Download and keep any production history from the monitoring app. If you're on a lease and considering selling your house, get the transfer-to-buyer process documented in writing before listing.

Sunnova's own site states plainly: “new owners have acquired substantially all of Sunnova's assets” through the court-supervised sale process, and instructs existing customers to “continue to make payments as usual until you receive updated instructions directly from SunStrong” (sunnova.com, accessed September 22, 2026). For anyone with an installation that was still in progress when the case closed, the same page states SunStrong is working with GoodLeap, a financing company, “to facilitate completion of certain in-progress installations,” and that affected customers would be contacted by their original dealer or a GoodLeap representative (sunnova.com, accessed September 22, 2026).

Business Model & Why It Struggled

Sunnova was never vertically integrated. It did not manufacture panels, inverters, or batteries — it bought equipment from third parties (Tesla Powerwall for batteries, a mix of Tier-1 panel brands, various inverters). Its installation work was handled primarily through a large network of local dealers and subcontractors rather than in-house W-2 crews. And while Sunnova owned its own leases and PPAs, the underlying financing still required capital markets access.

That model — asset-light, dealer-heavy, capital-markets dependent. was efficient for scaling fast in the NEM 2.0 era but brittle under rate pressure and the NEM 3.0 transition. The dealer structure also created the service-quality pattern that dominates Sunnova's complaint record: great sales pitch, mixed install quality, slow post-install service. When a dealer moves on or closes, Sunnova/SunStrong becomes the default servicer for systems the dealer installed, and the service queue backs up.

What “dealer model” means for a Sunnova customer

Sunnova didn't design, manufacture, or (in most cases) directly install anything. It financed and owned systems that independent local solar dealers sold and installed on its behalf, then bundled the resulting customer contracts — leases, loans, and power-purchase agreements — into portfolios (sunnova.com, accessed September 22, 2026). That's a materially different relationship than working with a company like Sunrun or Tesla Energy, which employ or directly manage their own install crews: with Sunnova, the entity that showed up at your house and the entity that owns your contract were usually two different companies.

That split matters for two practical reasons. First, service quality varied by dealer, not just by Sunnova — a complaint pattern the reputation section below already reflects. Second, the CSLB license that matters for your installation is the dealer's, not Sunnova's— Sunnova itself does not appear to publish its own California contractor license, because Sunnova wasn't the licensed installer of record; your dealer was. Check whichever company's name is actually on your contract and permit at CSLB directly — see how to verify a California solar contractor.

Reputation Before and After the Bankruptcy

Sunnova's pre-bankruptcy reputation was a weak point. BBB complaint volume ran into the thousands over the prior three-year period. Trustpilot ratings sat in the mixed-to-poor range, with install-phase experiences rated more positively than post-install service. Reddit's r/solar regularly warned new buyers about Sunnova's service response times. Legacy class-action exposure from earlier years continues through the new entity.

Post-bankruptcy, the customer-facing reputation has not improved. SunStrong's mandate is portfolio management — keep the existing customers paying, keep warranties from becoming a lawsuit. rather than growth or service excellence. For a California homeowner considering installing new solar in 2026, Sunnova is not a strong candidate. For existing customers, it's worth knowing what you have and what recourse options you have if service issues arise.

California-Specific Notes

Sunnova historically served California through its dealer network rather than with direct crews. Post-bankruptcy, new California installs through the Sunnova brand are limited to portfolio-maintenance additions. A California homeowner shopping for solar in 2026 is unlikely to get a compelling proposal through the Sunnova channel compared to financially stable installers operating in-state — and certainly should weigh the long-duration warranty question carefully before committing.
