Sunnova vs. Sunrun (2026): Battle of the 25-Year Solar Lease & PPA Giants
Forensic contract comparison of Sunnova and Sunrun third-party solar leases, escalators, buyout penalties, and dealer networks.
The Verdict: Neither — Avoid 25-Year Escalating Leases From Both Companies
Signing a 25-year escalating PPA or lease with either Sunnova or Sunrun is the #1 financial regret reported by US homeowners selling their homes. Sunnova is particularly risky because they rely 100% on third-party dealers—when the original local installer goes out of business, homeowners often wait 4–9 months for warranty repairs while Sunnova continues auto-debiting monthly lease payments.

🔍 FORENSIC ANALYSISForensic Pricing & Contract Breakdown: Sunnova Energy vs. SunrunHow sales commissions, dealer fees, and lease escalators impact your 25-year ROI
Under both Sunnova and Sunrun leases, you do not own the solar panels on your roof, you forfeit all local SRECs, and your monthly payment compounds upward every year for 25 years regardless of whether utility rates flatten.
⚖️ HOMEOWNER FAQDo I still have to pay my Sunnova or Sunrun lease if my inverter breaks and the system is offline?
Yes—stopping auto-pay triggers credit bureau defaults and late fees. While many contracts include a production guarantee, reconciliation typically only happens every 12 to 24 months at a fraction of retail electricity rates.
