Warranty
SunStrong won't honor the warranty: whose promise it was, and what to ask for
Updated October 22, 2026.
Owners often hear that a warranty or guarantee “wasn't transferred” to SunStrong. Sometimes that's true and sometimes it isn't, and the difference is in which document the promise lives in.
Which promise is which
- Promises inside your lease or PPA (repairs, the agreement's own terms) generally travel with the agreement to whoever now holds it.
- Separate company programs may be treated differently. In Sunnova's bankruptcy sale, some company-level guarantees and warranties were listed as liabilities the buyer didn't take on, and SunStrong has said so publicly in at least one BBB reply: a warranty “did not transfer to SunStrong Management” (March 30, 2026).
- Equipment warranties come from the panel and inverter makers, not the installer, and they're unaffected by a bankruptcy.
What to ask for
A written answer that names which promise they say didn't transfer, and which section of your agreement they rely on. That one answer tells you where you stand, and it's the record for anything next.

“After the letter was sent, it was mere days that they got back to me with a much more positive email looking into all our issues causing the total system to be down.”

What happened next: after her letter, SunStrong answered in writing within days, saying it would put billing and collections on hold, cancel auto-pay and set up a deferment while it looks into the system. See page 1 of her letter.
What this page isn't
It isn't legal advice. Agreements and state rules differ, and your own agreement wins over anything general here. I prepare documents at your direction; you review, sign and send them yourself.
