Legacy SunPower Corporation (Out of Business)Reviews of sunpower.com

I was confident that my SunPower system would perform as advertised, however, since day one I have been greatly disappointed by its low performance! I’ve contacted SunPower 10 times about the low production of the solar panel system they installed on my roof, however they keep telling me that the weather is the problem; although they can’t tell me why the weather is only affecting 6 of my 14 panels. Also, I have a friend nearby with a comparable SunPower system and the weather isn’t affecting his system which produces 100% of what it was designed to produce. My system is only producing 82% of what it was designed to produce. Six of the solar panels on my roof produce only 92%, 90%, 89%, 83%, 82%, and 69% of capacity. The SunPower warranty says that each panel will produce no less than 98% for the 1st year. When I looked at my roof, I noticed some problems with the system that SunPower installed. The wires coming out of several of the micro-inverters were bent backwards sharply going 180 degrees to another component. It looks like the wires were too short and they forced them to reach their connection points. Additionally, the production lights on several of the micro-inverters were not on. This was while the sun was shining brightly. Lastly, the solar panels are installed at a tilt angle of 14 degrees instead of 34 degrees. In my area, they recommend 34 degrees.

I started the process with Sunpower in March and was given an estimated installation date of June. After a lot of calls and emails I was able to get an install date of August 3rd. As of 8/31, 3/4 of the panels are installed and a few are in my backyard collecting dust and pine needles. I was told they will finish the install next week but there is no inspection date or activation date in sight. Save your time and energy (literally) and use another company.

This company is a disaster. I have their system in my home and it’s not been communicating properly. I’ve called customer service 4 times now over the past 2 months and have been blatantly lied to regarding getting this fixed and having a technician sent over. They continue to do nothing to fix the issue or following up with me. Stay away from this company at all costs!!!

Wow, Sunpower customer service is just awful. I’ve been waiting for nearly 2 months simply to get a repair appt on the calendar. Emails and texts go unanswered and all I get is excuses from the customer service number. I’ve waited on hold multiple times for a customer service supervisor who eventually just dodged my call. The roosters crowing in the background on the latest customer service call doesn’t exactly leave one with the sense that this is a professionally run company. I’m over 60 years old, and have never experienced such a poorly run company. Stay away at all costs.

In May 2019, I entered into a contract with SunPower Solar for the installation of solar panels and the replacement of my roof. The agreement explicitly outlined the terms of the installation, which included the removal and installation of a Torch Down roof. The terms also stipulated a Workmanship Warranty of 10 years and a Manufacturers Warranty of 25 years. In March 2023, I reported a significant leak issue that had developed in my roof. This raised alarm as the installation was relatively recent and the warranties provided ample coverage for such issues. After a prolonged period, a SunPower Solar technician finally conducted an inspection and confirmed that the installation of the roof had not been executed properly, leading to the leaks. The technician identified multiple locations on the roof that required attention. In May 2023, I received an email from SunPower Solar stating that the company would not take responsibility for the roof issue and that I needed to contact the subcontractor directly. This sudden shift in responsibility was both unexpected and alarming, especially considering my direct contract and interactions with SunPower Solar. Since May 2023, despite my best efforts to reach out to the subcontractor as directed by SunPower Solar, I have been met with a complete lack of response. This has left the leak issue unresolved and has led to further deterioration of my property due to water damage. I am deeply disappointed by the lack of professionalism and accountability displayed by SunPower Solar throughout this entire ordeal. The initial inspection by technician clearly identified that the installation was faulty, putting both the Workmanship Warranty and Manufacturers Warranty into effect. The sudden change in stance and the subsequent lack of assistance have caused me significant stress, financial burden, and property damage.

Warren Grennan came out to see what was wrong with my solar system. What started out as a routine job turned into a nightmare. Long story short, my system was not installed very well and was also pre-commissioned incorrectly. Warren arrived on time and saw everything that was wrong and went above and beyond expectations to make everything right! He is very knowledgeable and personable and assured me over and over that he will not leave till the job was done correctly!! Warren did an outstanding job!! People like him are a valuable asset! Thank you Warren.

*Update: you might notice that SunPower immediately got back to me once they saw this review to tell me they're going to reach out to make everything all better. This is just a show for you reading this review. After several days of not hearing from them, they got back to me to say that a customer service person would be reaching out, and guess what? It's the same person who has been "helping" me for the last few months who can't even answer the most basic questions about my issue and has asked me multiple times for the plans that they already have (because they're theirs!). Worse than useless. *Original review on 8/17/23 I'm not sure where to even begin with them. First, let me tell you that if you are approached by a sales guy named Ian Bamer, run. Sure, he did a great job selling to me, but while I've been struggling for over a year now to get my system operational, he's been copied on every email but has never responded. Either he has no asnwers, or he doesn't care because the sale's been made. Second, my journey with them is about 18 months, so I will try to be as brief as possible. * Note that I had a functional system in place already with them, and it was covering about 60% of my usage. I just did a remodel and added roof space, so wanted to add new panels. Should have been easy, right? Wrong! They had to shut down the current system for this process. * They worked out of order. The panel guys showed up first and were very surprised the electrical wasn't done. The guy was frustrated as though this happens all the time. * They screwed up the design out of the gate. I wanted the backup battery to be on the back of my ADU. They said no problem, but when the workers came out to do the electrical work they said it was not a good location because the wires would be at a 90 degree angle. We agreed to put the battery on the left side of the house. Not ideal, but at least out of the way since no one walks through there. Note that this was a completely different crew and they had no idea what the team prior to them had done, and it took them hours of phone calls and revieiws with their main office to get up to speed. * After about 5-7 more visits (each lasting days/weeks), all different crews, all having to spend hours on the phone trying to get up to speed (all disrupting me while I was on client Zoom calls, multiple times a day), they even had to get advice from my neighbor's contractor who had to walk them through the plans. But then they told me the battery couldn't go on the left side of the house because there was a bedroom on the other side of the wall. Seems like something they should have asked before they did all the electrical work! * And each crew who showed up told me that the crew before them made mistakes they had to fix. * So now the battery is on teh right side of the house blocking a significant part of the only open walkway to get to my backyard. * On top of this, they had to run a conduit through my valuable storage space in my attic to get to the new battery location. They promised it would be out of the way, but it is NOT! It's blocking valuable space. * To add insult to injury, one of the electricians told me the original location, the back of the ADU, would have worked perfectly fine. * They agreed to pay my PG&E invoices during the delay but they have only paid three months. Have tried to contact them on this, but have heard nothing back. * They lied to me for months saying the delay was because of PG&E, but PG&E provided me with proof that SunPower submitted the wrong plans, which was causing the delay. * We failed inspection 3 times because of those crappy plans. * I can no longer access my account at all. * I've written to their COO to tell him about this horrible experience and am considering reaching out to him again since I can't find an escalation path within their delivery team.

I had 17 Panels installed In February 2023, They are the 425W panels supposedly the best they offer. Late June, 2023 two of them stopped producing power and their installation partner came out 10 days later and determined that the microinverters were not working. They took measurements and photos that they forwarded back to SunPower for escalation, additional diagnostics and possible replacement of the two defective panels. I have attempted on multiple occasions to contact their service and product engineering teams for an update and a timeframe for resolution. On 3 occasions after providing my details and case# I was put on hold and dropped after being on hold for 20 mins. When I did get through it was a finger pointing exercise, namely our Product Engineers have a large backlog and it will take 3-5 days to get back to you (that was 3 weeks ago). Then the response was we have not received a report from our partner who installed your panels (yes they did receive a report). I am still in limbo with 2 expensive panels not functioning (approx cost was $2K per panel). As a former electronic engineer who has managed sales and support teams of over 150 people I have come to the conclusion that Sun Power support is seriously understaffed and poorly trained and that their panels are inherently unreliable with an unacceptable failure rate after only a few months of use. I was considering adding a battery to my solar installation but I will not be including SunPower on the list of my potential suppliers. I have researched other social media sites and the Better Business Bureau for comments on Sun Power and dissatisfaction with their service organization is a common complaint. They need to stand behind their product. They charge a premium price for a substandard level of service.
