My experience / My thoughts

The CORRECT solar system has saved me $ tremendously! My AZ home is equipped with a Sunpower system capable of storing energy and selling unused back to the provider (Arizona Public Service). I have lived there since 10/2019 and 96% of my Monthly invoices for energy have been credits, Ranging from ($21.00) to ($314.00) per month!!!! My TX home has a different system. One without capability to store the unused clean energy. The second it is produced and is not needed for my home, it goes to the provider -FREE OF CHARGE!!!! Does Sunpower have a Texas division? If YES, please have someone contact me to discuss. My contact info should be on file with Sunpower under Franklin Pryor 20760 W Minnezona Ave Buckeye AZ. Needless to say, I am extremely happy with Sunpower and have shared my experiences with many people. Keep up the good work!!!’ Respectfully and gratefully submitted Lin Pryor (aka Franklin Pryor)

SunPower Customer Service

Vida was very helpful with my issue today. The phone system got me connected to Vida without having to go through a phone system maze. My issue was resolved on my initial phone call.

Worst customer service EVER

I signed up with them in March of 2023. My system did not get installed until August of 2023. It took them another month to send a supervisor to ensure everything is good to go. It took them another three months to get a city representative to come out and approve the system after the initial inspection failed because of loose cables and improper installation. Their excuse for taking three months is that city jurisdiction would not respond to them. Meanwhile, two of my neighbors (in the same cul de sac) signed with other companies in May and June respectfully and their systems were up and running by September... If I am not mistaken my neighbors would have the same jurisdiction as I would, right?? In between all of this - communications had been horrible. Absolutely horrendous. I would wait a few weeks before I heard from them. Now, when I signed up I was told my offset is 130% and that my system would produce over 15,000 kWh per year guaranteed. I was also guaranteed that I would never pay my electric company since my system will overproduce so much energy. I was also told that billing starts 30 days after the system goes live. It went live according to them on 12/14. Before it went live - I was asked by them to go turn my system on myself. I was not comfortable (also was traveling) so I asked can you have a tech come and do it. It took another few weeks for them to send a tech out. Thank god I did not do it and the tech did. The system did not work as some of the panels were not working and the inverter wasn't either. The tech tells me that the system is not on. They however claim it was on as of the 14th of December. My expectation - I would not be billed because of what the techs said and what the sales reps said. 6 days later I received a bill. I reach out to them again - no response. I reach out to them again... 10 days later I get a message that, yes some parts of the system isn't working. a few weeks later - still waiting for techs to come. So I called corporate and finally the ball started rolling. I get techs to my house right away (they claim yet again my system is not on). I get email replies right away BUT they keep saying it's on and you will be billed. I dug into my electric bill to see if there was any energy produced. 46 kWh. from December 14 to January 18th it produced 46kWh. A $40,000 system produced 46 kWh when it's guaranteed it produce over 15,000 a year. In 34 days it produced 46 with 36 panels installed. Yet they insist the system is fully operational and running but they have a repair scheduled for 2 weeks out. Makes sense? I didn't think so. Now they're asking me to pay two bills with hardly any usage.

Please do not give this company your money

All of the positive reviews here are detailing SunPower’s service prior to and during the installation. This shouldn’t come as a surprise to anyone, because only fools would treat potential customers poorly. But when it comes to their treatment of existing customers, SunPower is unprofessional and unconcerned. We opened a case to address our non functional panels in summer of last year. It took two months for a technician to come onsite to replace a part of the system, which did not end up fixing the issue. Four months later, another technician comes to tell us we need to replace our micro inverters. Frustrating that it took so long to get to this point, but micro inverters are explicitly listed under their warranty so it shouldn’t be a big deal, right? Well, a month later, we get an email demanding that we pay $1500 for a replacement. Why? Because it apparently falls out of the scope of their warranty. This is because the damage was allegedly caused by a storm (in the middle of a California summer in 2022), which is not SunPower’s fault (as if it is ours?) thereby not their responsibility. Never mind the dubiousness of being able to diagnose that the root cause of the issue was a summer storm that happened a year and a half ago, what exactly does this warranty cover then? Issues that occur during installation? How is a customer supposed to verify the accuracy of the reports of their technician? And what were we met with when we asked for an explanation? Radio silence. If you are considering SunPower as a solar panel vendor, please do not fall for their warranty and friendly customer service as part of their sales pitch. It is a predatory facade to get your money in their pockets. Because, God forbid, if nature does something to mess up your system, they will slowly but surely ask you for more money.
