It’s been absurd that my project has… It’s been absurd that my project has been delayed many times, and nobody is even on top of my project. My project started in October 2023, and yet today is March 26th, I’ve been waiting for more than half a year, it still hasn’t been accomplished yet. What’s worst, we failed the building department Inspection. The Sunpower guy didn’t even try to fix it and left in the middle of the process, and it’s been seven days I’ve never heard back from them again . It’s been a very stressful process. I have to try to contact them a few times a week just so I can get a hold of someone on top of my project, otherwise it’s being ignored. I’m investing $50,000 cash in the solar panel project, expecting it to be reliable and giving me a long-term benefit. Now I’m not sure with this type of irresponsible service, how much I can expect in the future. I suggest people to look elsewhere, I do not recommend Sunpower. Received a response from Sunpower today on 3/27/2024 the review. Looking forward to their action on fixing the problem and when they will complete the project. I won't delete the review until things are done correctlly.

Deposit not returned Around six months ago, my system was installed and I made a full cash payment to settle my account. However they are refusing to pay me back the $1000 refundable deposit, and they have no reason not to do so.

Invertor Since early 2023, my solar panels have been generating zero or very little solar power. There have been multiple issues, some have been corrected. The one still not corrected is that one of the two invertors has not been working since at least since summer of 2023. I have been waiting over 5 months for the non-working invertor to be replaced. One would think a company like SunPower would have spare parts on hand. I was told they are still installing new systems, so invertors must exist!! Update - There have been 3 case numbers since April 2023 - #C03267717, #03376082, and #03690871. Also, per SunPower on 4/19/2023, SunPower was not communicating with the solar equipment for over 2 years so was not monitoring the performance of the system. I was not aware of this until the system was not working.

New solar installation and I was not… New solar installation and I was not able to connect or get the system running. Warren Grennan, from SunPower came out. He was SUPER nice and professional. Even better, he really knew what he was doing. It turns out the original install was done so poorly the system couldn't work. Warren spent extra time correcting those mistakes and stuck around until everything was up and running properly. Thank you Warren!
