SunPower warranty — Have a Warranty issue?

We have recently been receiving a lot of wrong numbers calling us to get a hold of SunPower about the solar panel system installed on their house. We're not the correct people to call for this. The 'old' SunPower did go bankrupt in 2024, but there is a 'new' SunPower who are the best people to talk to about your system, any repairs & warranty issues.

Call +1 877 299 4943

Phone support

Formerly known as Complete Solar they have acquired the rights to the SunPower brand, and other assets, and have now completed their rebrand trading as SunPower. Here's a link to our blog post about that.

What's happening at SunPower?

If you call the +1 877 299 4943 phone number you will be welcomed with a slightly overwhelming phone tree, but don't stress, this is the best way to get your answers. Here's a transcript of the phone message so you can plan ahead a little:
