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.

Warren from SunPower was great! I just recently moved into a new home and was having trouble activating my solar control box. SunPower sent out a tech, Warren, to help get it activated. Warren kept me informed via phone call for when he would be arrive and he got right to work. He was professional and explained everything to me once he finished the job so I understood how my solar worked. I appreciated how quickly he worked and how friendly he was! :)

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.

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

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.
