SunPower Went Bankrupt — What Happens to My Panels & Warranty?

SunPower Corporation filed for Chapter 11 in August 2024. If they installed your system, here's what it actually means for your panels, your warranty, your monitoring app and your lease — and what to do next.

SunPower was one of the largest and most respected residential solar brands in America, with roughly 600,000 U.S. customers. Its 2024 bankruptcy left a lot of those homeowners worried. The reassuring part first: your panels are still yours and still producing. Solar hardware doesn't switch off because a company restructures.

What actually happened to SunPower?

SunPower filed Chapter 11 and sold off its business units. Pieces of the residential dealer and new-homes business were acquired by other companies and, confusingly, rebranded under the SunPower name. But the entity that installed and serviced most existing rooftops isn't operating the way it did — which is why so many customers can't get anyone to pick up the phone.

Is my SunPower warranty still good?

Partly — and the distinction matters:

• Your panels: SunPower's premium panels are made by Maxeon (spun off from SunPower in 2020). The panel product and power warranty — usually 25 years — is backed by the manufacturer, so it generally survives the bankruptcy.
• Your microinverters: Many SunPower systems use Enphase or SunPower-branded microinverters, also covered by a manufacturer warranty.
• The "Complete Confidence" service warranty: This is the piece at risk. The bundled service, monitoring and workmanship coverage relied on SunPower being around to honor it.

Bottom line: if a part fails, you likely still have a manufacturer replacement coming — but you need someone to diagnose it, file the claim, and do the labor. That's the gap.

What about the mySunPower app / monitoring?

Your monitoring app may still display production, but the support and alerting behind it is unreliable post-bankruptcy. If the app has gone dark, or you've noticed a higher electric bill, don't assume it's fine — a quiet inverter or dead panel string can cost you hundreds of dollars a year in lost production before you notice.

I have a SunPower lease or PPA — is that different?

Yes. If you lease your system or have a Power Purchase Agreement rather than owning it, the lease itself is a financial contract that was likely transferred to or is managed by a financing partner — separate from the installer. Keep making your payments, and bring your lease documents to any evaluation so the servicing details can be sorted out.

What to do now

1. Confirm the system is producing (app or year-over-year utility bills).
2. Note your panel and inverter brands (check the inverter label).
3. Keep paying any loan or lease — that servicer is separate from SunPower.
4. Book a free independent evaluation to verify health and protect your warranty and NEM rate.

Frequently asked questions

Did SunPower go out of business?

SunPower filed Chapter 11 in August 2024 and sold off its business units. The original service operation no longer functions the way it did, even though the brand name was acquired and reused.

Is my SunPower panel warranty still good?

The Maxeon panel manufacturer warranty (typically 25 years) generally survives because the manufacturer honors it. The bundled service/workmanship warranty is the part at risk.
