SunPower Went Bankrupt: What SunPower Customers Need to Do Right Now

SunPower — once the largest residential solar company in the United States — filed for Chapter 11 bankruptcy in August 2024. If you're a SunPower customer, you likely have urgent questions about your warranty, your monitoring app, and who is responsible for your system now. Here's exactly what happened and what you need to do.

What happened to your SunPower warranty?

Your SunPower panel warranty did not disappear with the bankruptcy. SunPower's panel manufacturing business was spun off as Maxeon Solar Technologies prior to the bankruptcy — and Maxeon has assumed responsibility for honoring SunPower panel warranties going forward.

This means your 25-year panel warranty is still valid and still enforceable. You just need to contact Maxeon directly instead of SunPower.

What happened to your SunPower monitoring app?

The mySunPower app and monitoring platform have been significantly disrupted. Many customers have lost access to their monitoring data or found their app no longer updating. This is one of the most common complaints from affected customers.

Your monitoring access can be restored, but you may need to work with either Maxeon or your regional servicer to transfer the account. If your system uses Enphase microinverters, you can set up a separate Enphase Enlighten account to monitor production independently of SunPower's platform.

What happened to your SunPower installer?

SunPower operated through a network of authorized dealers and direct installers. Many of these have either closed, been acquired, or stopped operating in your area. Some regional operations were acquired by Complete Solar, which may have assumed certain warranty service obligations in your area.

To find out who is responsible for warranty service in your specific region, contact Maxeon directly — they can tell you which servicer, if any, has assumed responsibility in your area.

Step by step: what to do right now

1. Check your system is still producing power. Log into your mySunPower app if it still works, or check your utility bill for the past 2–3 months to see if your energy credits have changed. A sudden increase in your electricity bill is a sign your system may have gone down.

2. Document your system details. Find your original installation contract, warranty documents, and equipment specs. Note your panel model numbers (usually visible on the back of panels or on your original contract) and your inverter type.

3. Contact Maxeon directly for panel warranty issues. Visit maxeon.com and navigate to their warranty claims section. Have your system serial number, install date, and address ready. Maxeon has set up dedicated support for affected SunPower customers.

4. Contact Enphase directly for microinverter issues. If your system uses Enphase IQ microinverters (which most SunPower systems do), contact Enphase at enphase.com/support. Request a monitoring account transfer so you can access your system data independently.

5. File a warranty claim if your system has a problem. If your panels are underperforming or your inverter has failed, file a warranty claim directly. Solar Warranty Navigator can generate a complete claim letter and action plan specific to your SunPower / Maxeon situation in under 5 minutes.

What if my system needs physical repair?

If your system needs a technician to visit your home, Maxeon maintains a network of certified service providers who can perform warranty repairs. When you file a warranty claim with Maxeon, they will dispatch a certified technician — you don't need to find one yourself.

If you need repairs that fall outside the manufacturer warranty (like roof work near the panels or electrical work), you'll need to find an independent solar service company. Search for "solar O&M service" or "solar maintenance" in your area — many independent companies specialize in servicing orphaned SunPower systems.

What if my warranty claim is denied?

Don't accept a first denial. You have options: escalate to Maxeon's warranty supervisor, file a complaint with your state attorney general's consumer protection office, or contact your state's public utilities commission. Some states have specific solar consumer protection laws that provide additional rights.

Your Solar Warranty Navigator claim package includes escalation templates specifically written for denied claims — so you're prepared for this scenario before it happens.
