Legacy SunPower Corporation (Out of Business)Reviews of sunpower.com

My wife and I moved in on mid January 2024 and Sunpower took awhile to activate and were told to do it manually but no green light on the PV monitor. They sent a tech over and I met Warren Grennan and he did a splendid job with quality work. He took his time to make sure everything is up and running. He answered all my questions and guided me through the sunpower app. The green light is now on the PV monitor. Thank you again Warren Grennan!

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

All of these solar companies are a scam........they give you their sales pitch......a lot of their customers buy the system upfront......when you take that price and spread the cost out over 30 years, then you take in consideration the months during winter that you are drawing energy from the grid you are paying more for your electricity than unfortunately the electric company. Take some time to do the cost......it's a scam. There is no sales order number. No sale was made due to the above statement of conversation.

DO NOT THINK ABOUT CALLING AND SIGNING WITH THIS COMPANY STAY AWAY!! Our first project coordinator was amazing she would non stop contact me and let me know what was happening. One day I get a email that TRENT will be taking over and that’s when the nightmare started.. it’s going to be a year that we have the system on our roof and it hasn’t been turned on!! One day I lost my cool and wrote a beautiful email to Trent to let me know what was happening because my power company had sent me multiple emails wanting proof and I didn’t know what was going on so ofcourse Trent didn’t even bother to answer until 3days after the email was expired. Every time I ask him what is happening his answer: let me contact the team and that’s it goes on for weeks with nothing until I have to email him again asking to call me asap! He’s only called me once to let me know sorry your system is oversized we have to downsize. As always it’s the same excuse and no moving forward. today my husband called him and finally he picked up his line because he didn’t have my husbands number saved. So ofcourse first thing we did was ask for a supervisor or manager and first thing he did give me a second and hung up the phone. Called back he started making excuses oh my manager this that until he gave me a fake email to his manager and few mins later he calls my number letting me know oh this line is recorded this is my managers correct email and he will contact you today until end of the day and it’s already 9pm I’m still waiting for his managers call or email.  If you have another local solar company please run or if you’ve signed with Sunpower and have Trent as your project manager RUN!!

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

Update: It is now June 20, 2024 and I still have no battery back up!! I have had several visits from various technicians and an and a supposed escalation specialist. None of the techs could fix the problem despite supposedly having the “right parts” with them. No continuity of communication with Sunpower once the installation is done. If you are looking for a system that is maintained properly, look elsewhere. Original: 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!!!!

Istallati 4 kw di pannelli fotovoltaici Sunpower pannelli da 400 w. La resa è ottima per la posizione dei miei pannelli, producono circa 3800 w. Purtroppo non sono orientati perfettamente a sud. Mi riservo di aggiornare questa recensione nel periodo estivo così da avere il tempo di verificare i rendimenti con il sole allo zenit. Io per ora mi stoi trovando bene.

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
