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

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.

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

SunPower will not support you We have a system we leased from SunPower in 2012. We've never missed a payment and it has worked well. In Jan. 2024, our roof was damaged by a severe windstorm. SunPower is responsible for temporarily removing the system (at our cost) so that the roof can be replaced. I contacted them 7 weeks ago and they have not made any progress in locating an authorized dealer to do the work. I located a local solar company who would do it with permission from SunPower but they weren't interested. I offered to buy out the lease and they haven't responded. I am at risk of water damage to my house because SunPower support is non-existent. They'll respond promptly to emails but make no progress in resolving issues. In addition, they defaulted on a $300M loan last year and may have to declare bankruptcy or reorganize. DO NOT DO BUSINESS WITH SUNPOWER, YOU WILL REGRET IT!!

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.
