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!

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

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

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 Grennan was wonderful Warren Grennan arrived on time on the day we had the service scheduled. He was very knowledgeable and walked us through using the system after installation. He was friendly and professional and set up the system very quickly for us.
