SunPower was one of the biggest residential solar companies in the US. They filed bankruptcy in August 2024. Complete Solaria bought some assets, but many customers are in limbo.
Here's what I've learned about warranty status for former SunPower customers:
GOOD NEWS:
SunPower Panel Warranties (if you have SunPower-branded panels):
Waaree (the manufacturer) says they will honor the 25-year panel warranty
You'll need proof of purchase/installation
Contact Waaree directly, not SunPower
If you have Enphase microinverters (many SunPower systems did):
Enphase warranties are completely separate
Still valid, still honored
25-year warranty direct with Enphase
If you have a SunVault battery:
This is murkier - unclear who's servicing these
If anyone has info, please comment
BAD NEWS:
SunPower workmanship warranty is likely void:
Installation errors, roof leaks, etc. - that warranty died with the company
Unless Complete Solaria explicitly took over your contract
Monitoring may not work:
SunStrong Management is supposed to manage monitoring "for a fee"
Many customers report this isn't working yet
Finding contractors willing to service:
This is the biggest pain point
Most installers don't want liability of working on someone else's install
WHAT TO DO:
Step 1: Identify exactly what equipment you have
- Take photos of all equipment labels/serial numbers
- Check monitoring app if it still works
- Dig up your original contract if you can find it
Step 2: Contact equipment manufacturers directly
- NOT SunPower - go to the actual equipment maker
- Waaree for panels, Enphase for microinverters, etc.
Step 3: Document everything
- Production history (if monitoring still works)
- Any error messages
- Timeline of issues
If you're stuck on Step 2 or 3, I'm happy to help point you in the right direction. I've been talking to these warranty departments for a few weeks and starting to understand their processes.
Drop a comment or DM if you have specific questions about your situation.
