They installed the panels incorrectly and it lead to some flooding in our attic. Our plumber showed what happened but they denied everything. Part of our contract calls for them to wash the panels at least once a year. They've never done it since installation.

It’s been absurd that my project has been delayed many times, and nobody is even on top of my project. My project started in October 2023, and yet today is March 26th, I’ve been waiting for more than half a year, it still hasn’t been accomplished yet. What’s worst, we failed the building department Inspection. The Sunpower guy didn’t even try to fix it and left in the middle of the process, and it’s been seven days I’ve never heard back from them again . It’s been a very stressful process. I have to try to contact them a few times a week just so I can get a hold of someone on top of my project, otherwise it’s being ignored. I’m investing $50,000 cash in the solar panel project, expecting it to be reliable and giving me a long-term benefit. Now I’m not sure with this type of irresponsible service, how much I can expect in the future. I suggest people to look elsewhere, I do not recommend Sunpower.

SunPower is unresponsive several times with my experience. I actually had to report them to the BBB for lack of communication and response. First, when they installed the solar panels, I had my home inspection that failed, and they needed to come back. Not a big deal, but they took forever to comeback, and I had to hound them to come back out and they had forgot the issues that needed corrected and took 3 visits to get it correct. Second, when I had a roof leak they did not respond for weeks and then it turned to months before I heard from them. I had to get my own contractor and fix the leak myself. I plan on selling my home and getting solar again and will not be using SunPower due to their lack of customer service. Also, my co-worker used SunPower and had a similar experience as I did. You can have a great product, but if you can respond or fix issues in a timely manner then the product doesn't matter.

I actually purchased solar panels from this company about 12 or 13 years ago and I was very happy I did so they worked as expected and the company was a pleasure to work with, in fact so much so that I had 5 of my friends contact them, all of which purchased their own. Sadly this all changed with the company a couple of years ago. My unit was no longer producing the power it should. I contacted SunPower and almost a year later they resolved the problem. Yes I said that right almost a year. But that isn't even the worse of it, their technician who replaced the faulty unit created a problem with the electrical that caused the main breaker on my house to burn out. At the time I did not realize that, plus it was in the middle of summer here in Arizona, 100 plus degrees. The electrician that did fix the problem had to disconnect the solar panels to do so. This cost me over $1000, which I have been trying to collect for over 6 months now. The company just flat out refuses to work with you. They haven't denied it, which they can't, but they haven't reimbursed me either. Sadly I have spoken with two others that purchased the solar panels which have had problems to where they are unwilling to work with them as well. This company has gone, at least to me, as gone from a good customer service company to an extremely poor one. At this point if you are looking for solar panels, which I believe are a good investment, I would definitely look elsewhere.

I regret to say that my experience with SunPower Solar has been deeply frustrating and disappointing. I've been facing ongoing issues since July 2023, and their customer service has been abysmal, to say the least. In July, my solar service unexpectedly went offline. I promptly reached out to them, expecting a swift and professional response. Unfortunately, my concern seemed to fall on deaf ears. Despite my efforts to communicate the severity of the issue, there was no follow-through on their end. Hoping for a better response, I reached out again in August. Once more, I was met with promises - assurances that someone would be sent to address the problem. Yet, these promises turned out to be empty. No one showed up, and my system remained in limbo. What’s more frustrating is that they assured me my system was still generating power, which was difficult to believe given the circumstances. By December, with the issue still unresolved, I spoke with a representative named Brandon. The level of service did not improve. Brandon was unable to confirm whether my system was operational or not. He had me reset the system and assured me he would follow up the next day. That follow-up never came. This entire saga has not only caused inconvenience but also led to a lack of trust in their service and commitments. The lack of accountability and responsiveness is appalling. I've been patient and understanding, but the situation has gone from bad to worse with no resolution in sight. To anyone considering SunPower Solar of El Cohn, I would strongly advise looking elsewhere. The lack of reliable customer service and the inability to deliver on their promises has been a source of immense frustration. A solar energy provider should be dependable and responsive, especially when issues arise, and unfortunately, this company falls significantly short on both counts.

I can't speak to the product yet because they haven't completed the installation. For the reputation of SunPower and additional expense paid for the reputation and service, the installation so far has been a let down. We had 2 different site inspections to plan the installation for our house which we had to plan our FT jobs around. When the installers came last week, they were scheduled for Monday/Tuesday but by Tuesday, we were told the distance from the planned hub/battery to the electrical panel was "unexpectedly" long (how can that be after 2 site visits?) so would need to come back on Friday or following Monday to finish the electrical transfer. The team came on Wednesday to do some additional work and then came on Friday. On Friday, we were told that they were not ready to do the electrical transfer and we should plan to have it done Monday. On Monday, no one showed up and no one called. When I called SunPower, the CS rep reviewed the notes and said the Monday appt wasn't even listed. We have fulltime jobs where we have to coordinate in office or telework with our colleagues, work with a separate contractor for our house renovation we put on hold for the last 2 weeks, and also a large salt water aquarium so have been anxious about that and generator power for each of the days we were told to expect a power outage that didn't happen. I am now waiting for a 4th appointment for this electrical transfer. I was looking forward to this installation and was confident in SunPower but with this dragging on, it's rather disappointing.

Although I am satisfied with the product, the customer service is poor. went through 5 project coordinators and 10 months of delays for no apparent reasonable explanation before up and running. Biggest complaint was a false promo for a $1,000 gift card if you purchased/financed their system using their preferred financial partners, which I did. Made numerous complaints, was given a case number and after 15 months still getting nothing. Apparently the different departments do not have the ability to converse with each other and fix simple issues.

I purchased a new home that included a SunPower solar system. All was fine until the system needed repair just before the warranty expired. The system was offline for about four months during the hottest part of the year (when my electrical consumption was at its greatest). It would probably still be down had I not called and emailed SunPower relentlessly in order to get attention. I needed to spend $300 to get an affiliate to diagnose the issue (which SunPower said that I shouldn’t need to do). Also, I was told that I would be getting an “upgraded” (more-reliable) unit from a different manufacturer but that wasn’t the case. Very disappointed with how the support was handled. (Interestingly, I was told after the repair was completed that I may be invited to provide a survey. When I said that it wouldn’t be good and explained why, I never got an invite.)
