101 SunPower Consumer Reviews and Complaints

Original review: Nov. 1, 2017

We leased SunPower panels through Dave ** after getting several quotes. Prices were very similar, but other companies tried to get us to only purchase 50% coverage. We wanted more and Dave worked with us to accommodate our needs. Everything was on schedule and Dave was always very responsive. The installers were very polite and cleaned up after themselves.

The guy from SunPower that set up the system was incredibly polite, thoroughly explained everything and made sure all my questions were answered. To top it all off our system is producing more than promised and we are saving a ton of money!! I don't usually write reviews, but I have had such a good experience that I think a job well done should be rewarded!

Absolute nightmare of a company to deal with, once they get your money, goodbye anyone who is local, goodbye any timely responses/fixes, goodbye that good feeling you made the right purchase. Purchased a 15-panel system for our new home, it's been almost 3 months and the system is still not working. We have an appointment on Sept 21st, to look at the monitoring part, but if there is a legitimate issue we'll need to wait even longer to have the capable technician fix the issue. People all around us have had issues with them and their shotty contract installers, neighbor only has 10 of 15 panels working. The system is "on" but not producing any significant power to offset anything, shocking since 15 panels was suppose to supplant 80% of our power bill...

I went through Semper Solaris to get SunPower. If you look at the product and warranty you will be impressed however when you call Sunpower for assistance, they have the absolute worse customer service folks. My monitoring system has had an issue and now I am finding out that all my data is incorrect, there needs to be a change but now I will be in the dark for the rest of the year trying to figure out if I owe or not. Tried talking to them on the phone 4 different times and all 4 people were rude. All I wanted to know was if they could fix the issue and if the reporting would be updated with the right numbers. I love the company that installed my system but so disappointed with their service. I haven't rate anyone horrible but there is a first time and this is it!

I have called 5 times to schedule a service call. Each time same drill. The technician isn't at his desk but will call me back. Never a call back. It doesn't matter how angry I get or insistent. They don't care about service - only sales. Avoid SunPower at all costs.

I spent 41 thousand dollars on their product and install, the installer was a jerk. I spent another 10 grand fixing his installation problems, still I have 10 panels not working. They have replaced 6 before the 10 failed, they have since cut off the map of the panels on my roof so I have no way of knowing what ones are not working. I have a total of 51 panels. I do not recommend SunPower products or their installer Aram Solar in Calif. No matter where you are, stay as far away as you can from both. My panels are 3 yrs old. For two years I've had panel problems. Now Sun Power acts like they don't know who I am.

Original review: July 12, 2017

Purchased panels 3+ years ago and have had issues with their customer service since day one, way too many to list all here. Basically panels are not producing what is promised, told by technician we need 3-4 more that were installed and inverter also needs replacement. This means I have been paying more to SCE than necessary for the last 3 years. Of course my monthly report from SunPower says panels are producing as promised. Customer service is nil at best, and have been given at least 7 open ticket numbers for repairs, still waiting. Very frustrating, just told again they will meet regarding my concerns and should hear something next week... Seriously?

Original review: July 10, 2017

I would beware of this company! My wife and I chose SunPower after carefully reviewing all the solar panel company options. We chose SunPower because their panels were rated as technologically superior. While the initial installation was problem free, we have had nothing but problems every since and deeply regret that we locked ourselves into a 20 year contract with SunPower.

To begin with, the system stops working every few months or so, so that we have never had continuous service. But then, the nightmare begins each time we call customer service to have technicians come out and fix the problem. We generally need to call several times before we actually reach someone. Once we report the problem we generally do not hear back from anyone else and SunPower goes "missing in action" until we make several follow up calls and insist. Even at that, when technicians do call back, they expect us to be home during working hours to go to the side of our house and trouble-shoot around in the control box. Since we are not technicians (nor electricians or engineers) we can never resolve the problem on our own. Eventually, a technician shows up to fix the problem, but only after weeks of frustration and many phone calls to the company, some of them acrimonious, during which time we have no service.

On two separate occasions we have had to contact the manager Mabel **, as the only way to move beyond the lethargy, inertia, and incompetence of the company's customer service personnel and technicians. She has been extremely professional and immediately resolved the problem, first in April 2016 when we went weeks without the system functioning and then again in November 2016. There should be no reason we have to fight with the company in order to reach its manager to resolve the problem. Each time it is a major struggle to reach her. The customer service people insist that they, not the manager, will take care of the matter, but they never do. As I write these lines in July 2017 we have been without service for three weeks.

I loved my SunPower system when it was installed 7-8 years ago. However, the company that installed the system has since gone out of business. SunPower will only cover the product replacement - NOT the service involved in getting it replaced. In this situation, one of the wireless monitors has stopped working, and I am unable to track performance of the inverter - thus have no idea whether the system is even working, or how much energy is being produced. The tech on the phone was unfriendly, stuck to his script, and when I pushed, said "to be clear, the money to service the system will be coming out of your pocket." Not what I wanted to hear.

To be fair, I imagine that if the original installation company were still in business, they might have provided this service free of charge, but I have since spoken to other solar manufacturers who said it is their standard policy to provide this level of support to their clients who are spending thousands of dollars on their products.

SunPower state in their contract that there will not be a lien on my home. But after everything was done there is a lien on my home that they say they cannot remove. So for the next 20 years no bank would give me a loan until the 20 year lease is up. I am about to take legal action. Anyone who have the same problem can contact me.

Installation and setup is superb, very neat and quick. Service and setup is incredibly easy I would recommend the most amazing service. The financing option is very flexible I couldn't be any happier at the incredible financial options available to help me at the most of the best option. Their customer service is top notch, prompt at assisting and provide very useful helpful service. Always very polite at answering question and also very incredible at providing the best customer services that they can to help me with what I need. Very very amazing value at the most affordable pricing available to allow me to highly recommend. Couldn't have ask for a better value at an affordable price.

This was a big purchase for us so we had saved for a while and did not need to finance. We just bought straight cash because we don't like payments. It was expensive but so far we enjoy it and for the money it is a good value because we use it often so can't complain about that. SunPower’s customer service was also very good. They explained everything including how to work my solar generator and troubleshooting in case of an event in which it stopped working. When it was delivered the technician showed us exactly how everything worked including the manual so we knew how to do everything which is important because sometimes we use it where we have no cell service.

SunPower is something that we would recommend for others. You spend money on this but overall you end up saving money in the long run. It is good for you and your family and it is also good for our environment. They also have very nice customer service for us in our overall experience. We like it. The installation was easy too.

SunPower was the company for me. They have thoughtful, courteous, prompt service, technicians knew their job well, explained in detail what they were doing and were able to address all questions and concerns I had. Also, set up and installation was so easy. Making arrangements to look over products and telephone confirmations were prompt. The installation took as long as I was told it would and not any longer than expected. I was also able to choose a pay per month plan that fit my budget. This made it easier to get the work done that I wanted. Some other companies did not offer this option. The value I received was great too!

I would definitely recommend SunPower to friends and family. I felt the customer service was exceptional! I did have a question and it was answered quickly and efficiently. Also, the Financing options that were available to me were worthy of note. I feel the value of the products purchased was terrific and very fair as well. I felt it was not underpriced, making it feel cheap, and was not overpriced, making me feel ripped off. I also didn't have to worry about anything with installation or set up. It was all taken care of and very simple directions.

SunPower put them up in a couple days and it was crazy how fast they work. The financing options were great. The solar system wasn't fully paid but it was partly paid for because they helped out a lot and it worked out perfectly. The value was so much and it had 18 solar panels.

They were very accommodating and nice and respectful and I had a good experience with this company overall. They have very above average customer service from my experience in my honest opinion so props to them and their company for being so above average. Thanks. I would say financing options are pretty good and varied. It is a little on the expensive side but I was above average satisfied in my opinion. There was pretty good value in this company's product. I was overall satisfied with my experience of installation. They came to my home and helped me install. It was in a timely fashion which I was very happy about.

Companies can get away with not caring and doing their best. SunPower's installation could be a lot better. The setup was costly and confusing. It is a good value but the quality is uncharted and it seems they don't care. Moreover, customer service is not responsive to phone calls which can be frustrating. While their financial options are okay, the added interest is costly and could be better for consumers who are trying to live more environmentally friendly lives.

The workers who came to install the solar panels were very polite and also worked very hard in a timely manner. These workers were very professional and did a great job. The experience was great because they finished on time. The packages that my consultant provided to me over the phone were very reasonable and worked in my favor financially... The options provided were well explained and I was able to choose the right one for me. The solar panels provided will pay for themselves in less than 10 years... Great value for the price. I am very happy with my selection.

I didn't have enough energy for my big home. I hardly have any windows and needed more light. SunPower's representatives were very friendly and polite but they couldn't figure out how to help me. They came and did a great job setting the system up for me and told me it was exactly what I needed for my home. They knew what they were doing. However, the system wasn't nearly worth the price. It couldn't keep up with what was needed but they expected me to play their large prices. I couldn't afford the high payments they were asking for and they wouldn't work with me on what I could afford. I've found cheaper since then but after the bad experience I'm hesitant to do this again.

They were quick to set up and install. It seemed so easy that I could have done it. They didn't charge too much. I did notice that they could have done it a little quicker though. But they did explain things for me. It was decent dealing with these people and they opened my eyes to new things and helped me with my dilemma in figuring out how these work and what I can do to save on electricity in the future. They allowed me to either make payment or a one time deal which I was unable to make so I set up a great installment plan to make my budget and save a few dollars and cents. The value wasn't what I had expected... I thought I could save more or it would not be as expensive. It will take years to recoup my cost into what I have paid.

People that work at SunPower are very friendly. Their customer service agents were very helpful and questions were answered in a speedy fashion. I was extremely happy with all the information. Also, their installation experience is rated a ten and had very high standards. Moreover, the financing options that they had were very acceptable. The value of the products is 100% and everything was just right. I would totally recommend Sunpower.

Nice customer service provider. Easy to talk to. Very eager to respond to many questions. Wish they were more worldwide but still easy to obtain and maintain. Very easy to start up and finance... have many different tiers with many options to obtain. Affordable and very reliable energy source. Great value! Easy access and great website and online material. I received a better amount quoted than most other energy sources. Quick set up and very quick turnaround time. They came out very fast and had set up done in a pinch. I'd definitely recommend to any company or person.

Original review: Feb. 25, 2017

In September an authorized dealer by the name of Sunmark Solar installed a solar system on my home. They made several claims regarding warranty, potential savings and guaranteed power output. All were lies and I paid 41000 for a 10kw system that was suppose to produce close to 10000kw a year but instead has been down at least 6 times and has only generated 1200kw in 7 months. Sunmark the authorized dealer for Sunpower who had recently changed its name from Firstmark Advantage lied about how much the system would produce yearly and the savings before the sale. After the sale and the install when the system didn't produce they provided three different estimates of the expected output. First one for 10000kw which I received, then 7900kw which I was never provided and then a new one more recently which now states 6600kw.

They made false claims that I agreed to cut down every tree in my yard which was never the agreement. I am the process of taking legal action against them and Sunpower. My home uses 13000kw a year so you think anyone would ever pay 41k to have a system produce less than half than their yearly usage. As of now it is on pace to not even meet 5000kw. My electric bill is still high and in addition I now have the loan payment. My bill is now 550 a month.

After months of fighting with this company I had another solar company review the reports which I just received and they acknowledged the system should have never been installed without first removing the trees. The company used Unfair and deceptive business practices and misrepresented the product. Buyer beware. Do not BUY a solar system from Sunpower. If you purchase the system they will ignore you and point you to the dealer for any warranty claim or issues. The dealer who is often small will do nothing and will eventually disappear leaving customers who purchased the system out in the cold. So the 25 year warranty is completely worthless. The company changed its name from First mark Advantage to Sunmark Solar after several left the company because of their business practices.

They have good customer service but I believe they have a lot of clients to attend to so they might slack a little bit here and there but I am sure if the company expands in staff members, this can be fixed. The company needs to put more work there to satisfy customers. I do not find their financing system bad but I think they need to pay attention to their use of services. I strongly and honestly feel that there is really great value, I can not complain about that. Their services are all in short valuable to put it all in short.

The service that I used was quick and easy and the customer service rep was very knowledgeable and able to help with my every need. I would use them again as they were very quick to get the task I needed done completed and with ease. The prices were great too and that's always a plus! The prices were comparable to other companies. Not the lowest of prices but not the highest either, and for the services they provide I would say the prices are reasonable. The financing options available are great for large expensive purchases.

I was thankful to have chosen this company. It was a great overall experience compared to others I have had with other Solar power companies. The reps are very knowledgeable and the value was great for what I got. They continue to be the best decision I could have made. When they arrived with my solar panels for my out building they were ready to get to work. The entire process only took a couple of hours and it has worked like a dream since installation.

They really explained everything they were doing to me and made me a part of the process. I understand everything about my panel now and I'm happy about that! Not everything they showed me was outrageously expensive like I thought it would be. I got a solar panel that I never would've dreamed I could afford. I think I easily got my money back in savings since I got my solar power panel installed in my house. Plus it wasn't that expensive to begin with so I knew it would be that way. They set it up in a day or two and it was fully up and functional within a week at most if I recall correctly. On top of that I didn't even notice the workers outside.

The customer service personnel were nice. They helped schedule an appointment to have a solar panel installed on top of my roof. They went out of their way to help you. The financing of the installation was reasonable. They can work with you with prices and how to set up a plan to pay in installments if the price is an issue. The value of the product is good. I do not have any issues thus far since the installation. It functions properly and is efficient. Overall, it is good product. The setup and installation is good. I called a professional from solar company to set up solar panel on my roof. He was knowledgeable and experienced in answering my questions and setting up the installation.

They were great. I had no issues with them and they helped me with every aspect of the process. There was no question that weren't answered. There were several financial options available. All of the options were explained to me in great detail that I was able to make an informed choice on which was best for me. The whole process was not all that long.

All questions answered thoughtfully and intelligently. High quality products and service. Pricing was reasonable. Would definitely recommend to friends, family, and neighbors. Offered many viable options and process was fairly easy and painless. Best money we could have invested for the service and product. We've been ready to solstice our homes for a while and when we finally decided to do so, they made it so easy. We feel like we are doing a great deal to reduce our carbon footprint on the world and they've helped us with great service and prices. Installation went without a single hitch. Crew knew what they were doing. They were careful and conscientious. Couldn't have asked for a finer group of professionals.

The people at the company were very helpful and friendly which is appreciated for someone like me who is in the customer service industry. They explained everything in simple upfront terms which is needed because I have a family and we budget our money so the plan worked for us. It is a good value I think because solar energy is better for the environment so even if it's a little more than what we expected to pay it's still worth it. The installation people were quick and helpful in explaining all the ins and outs of using the products and troubleshooting problems so we liked that about them.

SunPower expert review by Zachary Shahan

SunPower is one of the world’s leading solar cell and solar module manufacturers, and it’s also a leading solar installer. It was one of the first solar companies to become vertically integrated, and was the first U.S. company focused on the home solar market to do so. Aside from residential solar installations, SunPower is routinely one of the top commercial solar panel installers in the United States.

  • High-efficiency and reliable products: SunPower’s solar cells and modules hold efficiency records for commercial solar technology – meaning they can produce the same amount of power as competitors in a smaller area. Its solar cells and solar modules are also known to be of very high quality. SunPower was the first company to offer homeowners a 25 year guaranteed level of performance on their solar panels or money back for the difference.

  • Electric vehicle partnerships: You can sometimes get a special deal on your solar power system and/or electric vehicle if you buy a SunPower system and certain electric vehicles at the same time.

  • Objective customer guidance: SunPower objectively helps you choose the best financing option for your situation (solar leasing, a solar loan, or straight cash), handles permitting paperwork, tax incentive applications, testing, monitoring and maintenance.

  • Availability: SunPower’s leasing option is available only in select states (solar leasing, in general, is only legal in select states), but its home solar loan option is available across the country.

  • Market: SunPower uses its own solar panels, keeping both its manufacturing and distribution branches in-house.

  • Price: SunPower’s high-quality solar panels come at a cost that fits that quality. SunPower offers financing options for consumers who prefer to pay in installments.

  • Best for: homeowners, small and large businesses, government agencies and nonprofits, leasing and PPA customers, solar beginners, cash and loan consumers and DIY solar users.
