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!!!!

Low Energy Production I am glad I came to this site because at first I thought I was the only one experiencing issues with this company. I had my solar system installed over a year ago and instead of saving money I have ended paying more to my electric company than I did before the installation. The panels have been producing little energy even on very sunny days and I can’t seem to get a technician out here to look at the problem. When I call Sunpower I am told it’s a problem else where and that I should contact my electric company. During the winter months my electric bill is almost $500 per month keeping in mind that my heating system is gas. The summer months are almost equal in comparison. Today for instance it a bright and sunny day and the panels are only producing .1 percent of my energy when I first checked and five minutes later it’s producing 3.8 percent. This system seems to be flawed and my attempt to get a tech to look at the panels have been futile because all I keep hearing from their end is that the panels are working.

poor customer service was checking my production from prior years discovered production went down 5000 kwatts from 2017 t0 2018 in fact Nov and Dec of 2018 no production just learned today problem 2 of 5 modules were not working waiting for dealer in Phoenix area to return call for service call to hopefully fix problem, on my nickel, where was there customer support aren't they suppose to watch for things like to this and notify you I did buy out my lease in Oct 2019 but had started before then GREAT CUSTOMER SUPPPORT

Quality Service by Warren Grennan 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!

This company is a FRAUD This company is a FRAUD! I purchased this system in March 2022 and since before install IT has been a nightmare! The system never worked for about a year now. I contact Customer service 3 times a day and everyone says something different. Technician came twice, they seat in the backyard for half a day, the leave the system working and the following day it does not work. same nightmare ... They are stealing my money. Now I am paying more to electricity provider and I have a monthly payment for 25 years with the bank. They are doing fraudulent practices I am very tired of them.
