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

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!

Low Energy Production I am glad I came to this site because at first I thought I was the only one experiencing issues with this company. I had my solar system installed over a year ago and instead of saving money I have ended paying more to my electric company than I did before the installation. The panels have been producing little energy even on very sunny days and I can’t seem to get a technician out here to look at the problem. When I call Sunpower I am told it’s a problem else where and that I should contact my electric company. During the winter months my electric bill is almost $500 per month keeping in mind that my heating system is gas. The summer months are almost equal in comparison. Today for instance it a bright and sunny day and the panels are only producing .1 percent of my energy when I first checked and five minutes later it’s producing 3.8 percent. This system seems to be flawed and my attempt to get a tech to look at the panels have been futile because all I keep hearing from their end is that the panels are working.

Waiting over 6 months now - Does not prioritize customers with warranty UPDATE: SunPower replied that they would escalate, but that’s been promised over the phone multiple times already. Canned review responses to show others that they are receptive to customers is more of a ploy. If they truly cared then they would actually resolve the issue immediately. If and when they do that, my review will reflect that. Original Review: My inverter broke over 6 months ago. The service person who originally came out explained the model I had was problematic with many inverter fails with other customers. He couldn't do anything and originally said it would probably take a month or so for a new inverter to get ordered and shipped. I was patient for many months, but after many phone calls and emails, all SunPower can tell me is that they are still waiting for the manufacturer and cannot give me any concrete details of when. The exact same thing every time I have called and the same thing they state when they email. It boggles my mind that SunPower has absolutely no visibility into their supply chain. Supply chain management/software has been around for decades at this point. Everytime I called customer service and asked to speak to a superviser, I was told it would not do anything, etc. I don't even know if my issue has been escalated properly, other than the word of the rep. And, in the mean-time, I have lost hundreds of dollars due to an inoperable solar system. It may even be thouands depending on how much longer SunPower takes. Had I known all this would happen, I would have gone to another service provider for a new inverter in the first place.
