Sunpower is a scam
Sunpower is a scam. They mis-represented how much I should receive per kwh of energy production by over double. If you're thinking of signing a contract with these guys... Don't. You'd be making a very expensive mistake.

My invertor has not been working since Novemeber 2020, tons of calls, no show service calls, a supervisor or anyone above him apparently are not available. EVER. Never a call back from one although I have left 8 messages as of date. and called customer service numerous times which is not in the US. I am stopping my automatic withdraw of payment, to me this is breach of contract! 6 months and still can't talk to anyone who can give me answers! I have had to true-up with electric company already. I want this Solar off my roof and I want to be done with this company!

In August 2020 I contracted with Sunpower for installation of 12 solar panels and a battery back-up system on the part-flat, part-pitched roof of my home in Mill Valley CA. They quoted me $30,000 and said the work would be done by 1 November. "Battery delays" meant that the hardware of the system wasn't installed until just before Thanksgiving. There followed almost FIVE MONTHS of nightmare. Nothing worked. The system wouldn't talk to the internet, the battery wouldn't talk to the central computer system/hub, and so on. They had to make half a dozen separate visits, often with huge vans and a team of up to five people, with endless exhausting arguments, phone calls and emails in between. The installers (ESA-Solar) blamed Sunpower for defective parts, Sunpower blamed the installers for incompetence, and so on all the way through the winter and early Spring. Finally, Sunpower have offered me a 5% discount on the price they're charging, in an attempt to make up for the dismal mess their incompetence created. If you want to keep hold of your sanity, avoid these people. They look very glossy and professional, but in fact their systems are unreliable and they will go to great lengths to string you along.

The Worst Solar Company On the Planet 4 years of a dead system. Damage to my roof and home. Out thousands of dollars on a lease. Beware they will screw you over. I’m tired of the fraud, it’s time for action.

’ve had Sunpower for about 3 years and now I am in the process of selling my home and the new buyer agreed to take over the lease. However, Sunpower is forcing me to pay a $300 filling fee in order for them to provide UCC filling documents to the mortgage company of the new buyer. This is during a pandemic where I am barely surviving and able to provide for my family which I’ve mentioned to the representative that I was speaking to but none of that mattered to them. This is a lesson learned, I will definitely look into other companies in the future because of this experience and also, my monthly solar panel bill was $81 which is more than any other solar panel company out there. Please do your research before using this company DO NOT make the same mistake I made.

Sun power product is of very low quality. Have it on the roof for last 2 years. Have problems like 2 -3 months a year. And the customer service is pathetic. Maintenance will be rescheduled again and again. Don't waste your time, find someone better.

Horrible customer service. Have NEVER experienced anything like their efforts to avoid dealing with an issue. Our inverter went out last year. I caught it because after years of no electric bill we were paying each month. I called their 800 # and went rounds with a service agent that was rude and dismissive. He ignored logic (e.g. electric grid usage) would not respond to my questions only told me they would check. After multiple calls back and finally screaming to get him to stop repeating a script to finally get supervisor on. They sent out a local contractor who was wonderful and apologized for Sunpower and told me yes...the inverter was dead like many that age. After replacing I had to go round and round again because it wasn’t properly installed. And months later it’s still not performing as before. Exhausted. Do NOT go with them if you have any choice at all

We signed a contract with Sunpower in August 2015 for the installation of solar panels on our roof and a 20 year contract (the solar panels are actually leased to us and we pay a month flat energy bill to Sunpower). We were told the installation would take a couple of months and we would be supplied with enough solar energy to meet our expected needs and save a lot of money. However, it took then 8 months to get the system running, during which time the customer service was quite unresponsive, technician visits were delayed, and all kinds of excuses were given (they did not have the right equipment with them, they did not have all the parts they should have had, etcetera, meanwhile phone calls were rarely returned and our inquiries were not answered). Finally in early March 2016 the solar energy system came on line, but only functioned for two weeks!, at which point it malfunctioned. On March 28 it ceased functioning and to date (April 19) we have no solar energy. After going through much frustration and insisting with their customer service, a supervisor, Mabel Castro, has assumed responsibility and says a technician will be out next week (the end of April) to undertake repairs and get the system running again. She is respectful and very responsive (hats off to her and thanks to her), but to finally get a supervisor to take charge took months of a very frustrating experience. And bottom line? - in 9 months we have only had two weeks of solar energy.
