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.

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.

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! :)

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!!!!

All of these solar companies are a… 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.
