Why no spare parts in stock, lack of urgency? Our solar panel and battery system has been off-line for at least 5 days. Sunpower support says there is an assembly called the Gateway that appears to be broken. They have to order one and they will let us know when it comes in and they can schedule an installation. In the meantime, we are buying all of our power from the grid. I don't understand why Sunpower can't keep some spare parts in stock. I suppose it's cheaper for them to operate with no backup stock. Also, on a previous outage, it took something like a month to get a service appointment. Couldn't sunpower schedule a service appointment now, using an estimate of the part's arrival? To us this seems urgent, and sunpower doesn't seem to get that.

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.

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!!!!

New Home in Santee I just bought a new home in Santee and I met my SunPower tech Warren Grennan when he was doing maintenance on my neighbor's home. I asked him for some insight on my home and he took the time to educate me on the type of solar panels I had and what to expect. Fortunately, it was good news that I didn't need additional panels. Once we moved in I had SunPower come out to make sure everything was working properly. That was a good move because there were some things that needed to be upgraded and reconfigured to work optimally. Warren set up shop in my garage and walked me through the app on my phone and let me know what to expect consumption and usage wise. He was very thorough and kind. Warren made sure I didn't have any questions before he left. I even picked his brain about battery walls which I plan to do once we decide what kind of electric car we will buy in the future. I wish more companies had a Warren they could send out to make sure these things are done correctly. Thanks for taking care of us! Lastly, I was told by our community that this process could take weeks/months. This isn't even our second week in our new home and we are already up and running. #Awesome

Worst of the worst customer service I purchased their system two years ago, and it has been reliable for the most part. However, my experience with their customer service has been abysmal. Without any explanation, they've rescheduled appointments three times already. Now, I'm told I have to wait another three months for someone to finally come. It feels like they might be a one-person team. Needless to say, I'll be cautious about choosing them again. I've heard similar complaints about other big companies like Tesla. Once they install your system, it seems like support becomes nonexistent. That's why I'm inclined to explore smaller companies that prioritize responsiveness to their customers.
