The Company Behind Your SunPower Panel Warranty Is in Insolvency Court. Get Your Paperwork Ready Now.

If you have SunPower-brand panels on your roof, the 25- or 40-year warranty on them has been the safe part of the deal. It belongs to the company that built the panels, not the installer that sold them.

That company is Maxeon, and since April it has been run by court-appointed managers in Singapore. Nasdaq delisted its shares at the opening bell on October 12.

Your warranty hasn’t been canceled. It’s just now a promise from a company in insolvency court. Treat it that way.

How the safe warranty got shaky

SunPower went bankrupt in August 2024. SolarReviews says it had nearly 600,000 residential customers. Maxeon, which made SunPower-brand panels, said it would cover warranties on the panels it built.

Then Maxeon ran into its own trouble. Its April 1 SEC filing blames U.S. Customs for blocking its panel shipments, along with price competition and the tax-credit changes in the One Big Beautiful Bill Act. Customers were already suing it for “upward of $70M.”

Two Deloitte insolvency practitioners took control on April 9, and the court made it official on May 29. The directors’ powers “cease,” per the filing. Noteholders then declared default and demanded payment from subsidiaries that still carry the SunPower name.

What that means for your claim

Judicial management can end three ways, according to Maxeon’s own filing: the company survives, creditors accept a deal, or the assets get sold for more than a liquidation would bring. From the day Maxeon applied, the filing says, nobody could start or continue a lawsuit against it without the court’s permission.

The filing says judicial managers are typically appointed for 180 days. Counting from May 29, that’s late November unless they get an extension. File that date away.

Even a healthy Maxeon wasn’t writing a blank check. Its current U.S. warranty, dated May 1, 2026, pays up to $250 to pull and reinstall a bad panel. If it refunds instead, the refund on a 40-year warranty drops 2.78% a year after year five. And the 40-year term only applies if the panels were registered within six months. Otherwise it’s 25 years.

Do this now

1. Find your model and serial numbers. Maxeon’s U.S. warranty lists SPR- model numbers. Check your contract, your installer’s documents, or the panel labels.
2. Collect your proof. Itemized proof of purchase or installation and your registration. Maxeon can reject a claim if the documents are thin.
3. Check your production today. Compare this October against last October in your monitoring app. If output has dropped hard, email [email protected] now. A claim on file while the company is still operating beats one filed after the restructuring ends.
4. Selling the house? The warranty transfers only if you give notice within 90 days and the buyer registers the panels.
