Cannot get data through the app for my panels' solar production. It is an intermittent problem - hit or miss when I log into the system, I get a message "connecting data... it may take up to 1 hour for you to be able to access your site. Please try again in 1 hour" that does not change hour after hour. Without the data, I have no clue what the panels are doing and even if they are producing at all. Update - I have two sets of panels that were installed on two separate occasions. I was unable to get a consolidated view of my panels' output and needed two separate log-ins to view their energy production but it now seems that SunPower has combined the two sets, which is why one logon is no longer able to get data - at least this is what I presume is the case. I was not informed by SunPower but I've increased my rating because if this is the case, it's the right thing to do.

Monitoring system has not worked in months and our electric bill has been between $235 - $335 for the past 4 months in 2022, compared to $20 - $33 for the same months in 2021. Customer Service is basically non-existent, with empty promises and no follow through or returned calls.

Installed my SunPower residential solar system in January 2015, and was promised a 10-year warranty, with no mention anywhere that there are different warranty periods for different system components. Had to have the monitoring systems upgraded and changed within a few years under warranty, but then the monitoring system stopped working again December 2021. I found out in February of 2022 and contacted SunPower, who then referred me to Semper Solaris (the installer), who then referred back to SunPower. Now after 8 months of waiting, I received a call from Semper Solaris saying that the new monitoring system, called PV 6.0 is not covered by SunPower Warranty and that's why it's taking so long, and more than a dozen calls and emails and endless frustration. The entire holdup, I was told, is that I have to pay $950 for the new monitoring component, the PV 6.0. Bottom line, do not trust SunPower's warranty. When I was sold my system back in 2015 I was told SunPower has the best warranty in the business. This has proven to be a bunch a hooey. I paid a premium to have an "American" SunPower solar system, but don't let this fool you, "American" is just a mask they hide behind.

Its been over a month now. Many calls to tech support. My SunPower app does not work at all. It was escalated to the level 2 Database team apparently. They have a 5 day SLA. That came and went with no response. I also heard from someone named Pierre from the "escalations department". He asked for some info a week ago which I supplied within 2 hours but haven't heard anything since. I've called him to ask for an update. No response in 3 days. Called back into tech support level 1 and they reached out to both teams above them for status, and they did not respond to the gentleman on the phone with me. Also, on the phone with them while writing this review. Just found out they closed the level 2 escalation ticket as resolved, but its not fixed. Apparently they closed the ticket without even testing to confirm it worked... it did not. So now I have to create a new ticket and start the process all over again. Zero confidence it works any better next time but really don't have much of a choice here. There are poorly designed and managed customer service processes at Sunpower. No accountability, don't meet self imposed deadlines, don't respond back. I would give customer service a zero if I could, but 1 star is the lowest.

Water damage to my ceiling from penetration of solar panel.Had to wait weeks for them to get to my house to look at it. They were over 2 hours late but patched the area their seal failed but haven’t taken responsibility for damage to my ceiling and told me to contact my insurance company. I asked about having panels taken down in future if I needed a new roof and was told there’s a fee but haven’t been to the amount.performance report down for 3 months and information regarding usage compared to production gone. Edison now has me owing money instead of being credited for over production. First couple years Edison owed me $600+ last year I owed Edison $500+. This year I owe $300+ so obviously my production has Gone down. I was told my roof was warrantied for term of lease and it’s not it’s for 3 years. My panels were installed in 2017 so all cost are now on me. Disappointing

If I could give this company zero starts, I would. DO NOT USE SUNPOWER. Had a new roof rolled into the deal. The roof started leaking after the solar installation. Sunpower did an "investigation" and took zero responsibility.

My system stopped reporting and producing power in June of this year. It did the same thing last year for 3 months. The tech who fixed it in 2021 said the inverter was poor and probably needed replacement but Sunpower said no at the time. Over the last 4 months Sunpower has had a tech out to my property 3 times. The system has not worked each time after the visit. I was told at the last visit that Sunpower would replace the inverter and to expect a call to make appointment. Received a call from Sunpower saying my inverter is now fixed and the issue is a monitoring component that is not covered by warrant and they are closing my case# 02820883. I objected but Sunpower said they could see that system is working but I can’t and need to get monitoring system replaced. I don’t see how they can monitor system when I can’t. Further had this been fixed properly and not taken so long it probably would still be under warranty. My inverter light is still red which means it’s dead. Bottom line: SunPower has not fully addressed this issue and I continue to be without power production. I’m desperate for assistance.

I purchased a home over a year ago with a $120,000, two year old SunPower system. The solar system worked great for nine months but has now been down for three months (I have the Edison stubs I have had to pay.) As commented by most other reviewers, I too found it impossible to talk to a tech. I found a typical 2 hour wait to talk to anyone. After finally getting through I was told a technician would be out at my house on December 21. This would mean I am without solar for five months and will have to pay 5 months to Edison. I can make an effort to talk to a tech to try for an earlier tech support time but they have already told me this was an earlier time. I notice that SunPower respondes to every posting but I sure like to hear from the other reviewers the satisfaction they got form the SunPower reply. I highly recommend those who have a problem to file a report with your states Utilities Commission. Here in California they have a division just for problems with solar systems.
