8 weeks to get service One inverter stopped working resulting in 30 panels going down. I "chatted" with someone who sent me directions to reboot the inverter but you need to be an electrician. Best appointment available is 7 weeks out

Unacceptable! 5 months with no battery backup! I purchased a SunPower system (panels & 2 SunVault batteries) in late September 2023. Since Nov. 6, 2023, the two batteries we purchased are basically doorstops due to (apparently) several malfunctioning parts (microinverter(s) and a relay). I have called the 1-800-SunPower number numerous times over the past several months and have gotten no useful information from them except for a case number, #03621287. The consistant answer is that the parts are "on order." The SunVault (battery) line is worse than useless as no one ever answers it. Have contacted my "project manager" several times (email only - never answers his phone). He has only told me to call the 1-800-number. I am very discouraged, especially when I read that Sunpower is currently being sued by shareholders for not properly disclosing inventory levels. A previous lawsuit for selling systems with defective inverters (settled 2022) has caused me great alarm due to the similarity of the case to my situation. SunPower, please help me!!!!

Warren the GOATechs Warren was great, fixed a problem left behind someone who was fired from the company. Could have given up and left but stayed to fix a complex problem. For Warren specifically, this review is for him

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.

RUN..... RUN... customer service will never allow you to speak with a manager or a supervisor. Have been having issues with our solar panels generating power since 2/24/23. Finally fixed 1/2024 but not before having to pay Edison $2,537 right before Christmas 2023. Once it was fixed, they ran a performance guarantee test and they only refunded us $432, really! Now 3/21/2024 as of 2/3/2024 again we are not generating power... really again! Currently fighting the refund and now have a new open case for not generating since last month. In contact with Nilasco Caguimbal | Escalation Specialist but he usually only response once a month if I'm lucky. DON'T RECOMMEND THIS COMPANY AT ALLLLLLLLLLLL!!!
