Expert review
Sunpower is an American company manufacturing solar panels both in the US and also in Mexico and China. It manufactures the most efficient solar panels on the market.
Two of its monocrystalline X series panels rank as both the most efficient solar panels on the market, with a peak efficiency of 22.1% and 21.5% respectively, and were also the most installed residential solar panels in America in 2018.
Sunpower offer the longest product warranty of 25 years to go with their 25-year power output warranty.
However, Sunpowers' financial position is not as strong as its peers LG Solar, Panasonic and Tesla. They made a large loss in 2018 and their new assets declined accordingly.
This has lowered our overall rating of their solar panels. To date Sunpower has done very well to retain premium pricing for their brand but will face more and more competition from very high-quality solar panels manufactured by other companies.
All of the top 20 brands of solar panels are now very good and very reliable making it harder to justify a price premium.
Sunpower are expensive solar panels, very good, but expensive. Sunpower only sell their residential solar panels through trained dealers. They do this to maintain quality and ensure their panels are installed properly. Whilst this is a good thing it means the average price of a residential solar system installed with their panels is still well above the $4.00 per watt level. This has caused us to rank them below other companies on a value score.

the support is terrible you call them, and you have wait whatever they want, the engineer department, I have issues with my monitoring system
Hello Juan, we apologize for the issues you are experiencing with your SunPower monitoring system. Please send me a direct message with your contact information so that I may assist.
Sunpower doesn't stand by thier contract
sunpower thoroughly examines your roof condition and then signs a contract that they are responsible for the roof the solar panels are on. That is BS. After spending 1k to paint all my ceilings a storm came and a leak appeared. Took them a month to get someone to my house. Inspector fixed it and stated the i initial installers didn't secure the panel to a beam which is what they were supposed to do. I requested compensation they declined and said that I need to get a 3rd party involved. So now im going to get my lawyer involved and they just lost the other 107 homeowners in my community. SUNPOWER INSPECTED THE ROOF TO ENSURE IT WAS IN GOOD CONDITION. A year later you want to tell me there are numerous leaks. When there's not. Only a leak where the inspector stated it was incorrectly installed!! I will be suing for way more than having my ceiling repainted just for the principal that ypu do not stand by your contract.

We have brand new SunPower panels and panels that are nearly 10 years old that are working flawlessly.
SunPower Residential ---Arrogance and dishonesty
In April 2019 we replaced our 16-year-old solar array that was shaded by neighbor’s trees with more efficient SunPower 370W panels. I read the advertising claims about the communications app and thought it would be useful for adjusting the time of use with our electric car and all-electric home. The new communication unit is PVS-6 replacing, according to the installer, Northern Pacific Power Systems, the former poor PVS-5 unit. After a few months it was apparent that even the installer couldn’t get useful data from the SunPower-modified Enphase inverters. I communicated with Ryan Pickering: SunPower is rebuilding our monitoring platform, which we originally built in 2001. It has been a challenging update and I look forward to completing the project soon. SunPower is indeed releasing our residential battering in mid-2020. Monitoring is a critical piece of storage and therefore we are all working hard to solve this matter. Northern Pacific is visiting our engineering office this week and will be discussing some monitoring cases. Tony, as always, thank you for your patience. Ryan Pickering Residential Manager: Northern California Coast In September 2019 we installed Tesla Powerwalls and with their communication system I could monitor the performance of our panels. On April 14, 2020 our power output suddenly dropped by 20%. And has never recovered. The power curve went from a bell-shaped curve with maximum output of about 6.5kW to a chopped top form with a maximum ever of 5.3kW. Four months have lapsed trying to get SunPower to address this loss of power. A Customer Ticket Case No. 0213358 was opened with Jeremy Sibug as Manager. Three months elapsed with him not replying, even to the SunPower customer service reps when I’d call to learn the status. On July 14, 2020 he replied: Our Design Team and Engineering Team could not find any problem in the system. Both teams already checked for any possible errors or issues. One recommendation was to trim down the trees nearby, if not yet done. I’m sorry that our teams could not find any problem on your system. Let me know if you still have questions. Thanks! Contrary to this useless guess, the SunPower system was installed away from all shading. They seem to have not talked to the installer. Today, August 6. 2020, Northern Pacific Power Systems is removing the SunPower-modified Enphase inverters and PVS-6 and installing un-corrupted Enphase inverters with Enphase communication. Through these four months SunPower has demonstrated arrogance and dishonesty as a company culture. The photovoltaics in their panels may be exemplary but their damaging the Enphase inverters for their private communication system is a disaster. Northern Pacific Power Systems in the end seem to have fixed my system but why a reputable installer would market SunPower to a homeowner is a mystery. I imagine most homeowners assume their system is delivering the advertised power and, unless they have the Tesla softwa
Sun Power Rocklin, Ca. TOTAL RIP OFF
We went with Sun Power Sept. 2018 with a 12.4Kw solar system. We gave Sun Power the tax right off {about $9K} for what we thought was favorable 10 year 4% loan with Digital Federal Credit Union loan. We just this month found that what we thought was a $303.00 monthly payment just went up for the duration of my our 8+ year loan to $438.28. We failed to read the fine print on our loan. We had a roof leak under our panels shortly after the install. After two no shows and sending a crew out twice no attempt was made to fix our roof leaks. I had to fix myself. Russ. Grass Valley, Ca.

Outstanding Service from Freedom Solar by SunPower
As a California and Texas homeowner for more than 20 years, I can tell you that this was my first time looking at Solar options. It was long overdue! I conducted my research and analyses on four top Texas companies by holding in-home interviews with each one of them. Of course, they all say “we’re number one” over their competitors. However, we all know that there could only be ONE number one. These four Solar company representatives had their own right to claim a particular featured “edge” against the competition. The lowest bid I received from company “D” was $13,170; the highest bid from company “C” was $27,772; the other two, company “A” and company “B” fell in between those estimates. Company “A” really stood out, not in cheapest cost, but in their professional salesmanship and presentation of their products inclusive of their warranties. I further read hundreds of reviews from an independent website https://www.solar-estimate.org/solar-panels/texas/ which is not related to any of the Solar installation companies. Company “A” was customer rated Number One at 5-Star for their service and products. This company is Sunpower by Freedom Solar https://www.solarreviews.com/installers/freedom-solar-power-reviews/ and their Senior Energy Consultant is Mr. Stephen Galaviz. Mr. Galaviz is a true professional and provided me and my family with a Solar Energy presentation that no other company even attempted to do. He precisely answered my multitude of questions about products, workmanship, warranties, and service after the sale. Moreover, he provided a tangible sample of his company’s panels and the competitor’s, to my surprise the Sunpower panels were flexible and very well made in comparison to its competition. Freedom Solar is the company I selected to build/install my Solar Energy system, thanks to Mr. Galaviz and Mr. Aaron Heth who worked with me to obtain the most efficient and cost-effective system for my family and home. I am truly appreciative of their knowledge and service throughout this installation, and look forward to developing a long-term business relationship with SunPower. Thank you so much and Semper-Fi! “Gunny” Salazar, USMC-Retired
No Solar energy produced for week in a month
I don't know but customer service is not that good or fast enough like their Solar system. We had 8 panels installed, but last month 8 hot days no energy produced. Last 5 hottest days including today when its 100, no solar panels working....I don't know how to rate the company.
Hello Mike, I apologize for the delayed response and your frustration related to your Customer Service experience. Please send me a direct message so that I may escalate your concerns for prompt resolution.
Premium panels and great price
The Sunpower panels look great and perform even better. I’m very pleased with Sunpower and Savkat Solar.
Worst customer experiences I have ever had
I would like to submit a complaint, I have had one of the worst customer experiences I have ever had dealing with Sunpower Solar to transfer the lease for the sale of my home. I had to call several times and spend hours on hold to get the lease transfer documents in the first place (I was repeatedly lied to and told I would receive the docs by X date, then nothing would happen and I would have to call again). Finally, once we signed and sent everything in, Sunpower promised to get the documents in today so we could close on time. Now Sunpower missed yet another deadline with no contact or any information whatsoever. I paid $300 for this solar lease transfer and want a refund, and if the home sale runs into any issues, I am going to hold Sunpower legally responsible for my losses.
Hello, We are sorry to hear about your recent experience. We would like to see how we can help. At your earliest convenience please send a direct message with your contact information. We will review your account and have an executive specialist reach out to you to address your concerns. We appreciate your business and value your feedback.
