Founded in 1985, SunPower Corporation is a solar company that prides itself on delivering reliable energy and long-term peace of mind for homeowners and businesses. The company is a pioneer in the industry and currently holds more than 500 U.S. patents for solar technology.
SunPower is known for its top-quality and high-efficiency solar panels that generate more power than conventional solar technologies. SunPower Panels have an attractive appearance and come in a few different size and wattage options to help both residential and commercial consumers get started with renewable energy. The majority of SunPower installations are completed by its expansive network of certified dealers.

SunPower offers three different payment options for customers to choose from that help them save on their electric bill: solar leasing, purchasing with cash, and financing with a loan.
With the lease option, SunPower Capital owns the system and the customer effectively rents the system via monthly payments. The lease comes with a 25-year performance guarantee, as well as easy options in case the customer needs to transfer the lease.
SunPower also offers outright purchase and financing options for customers interested in the tax credits and other incentives that supplement the benefits of solar power ownership. Loan terms for solar systems typically range from 5 to 25 years and do not have any prepayment penalties attached.
The cost of a SunPower solar system ultimately depends on several factors, including current energy usage, available amount of unshaded roof space, the local utility’s net metering policy, and other factors. The easiest way to learn exactly how much solar will cost you is to obtain a free quote from SunPower.
SunPower has been on the cutting edge of solar technology for more than 30 years. Consequently, the company excels when it comes to innovation and design of solar cell equipment, enabling customers to be confident that they will have the highest-quality solar products expertly installed on their homes.
In fact, the solar installer provides the highest-efficiency solar panels you can buy today. The solar panel manufacturer engineers elite solar modules that are up to 22.3 percent in solar panel efficiency, and carry a temperature coefficient of -0.29, meaning output will not be negatively effected because of excessive heat. Each SunPower panel is made of anti-reflective glass and coated with anti-reflective film for optimum durability and to ensure that they capture as much sunlight as possible. In short, SunPower cells provide the best value for your money.
The SunPower X Series solar panels excel in terms of power generation and deliver 44 percent more energy per watt than competitive products. This means that SunPower can provide more clean power for its customers' homes with a smaller solar installation and fewer panels than other companies.
Every SunPower solar panel also boast 75 percent more energy per watt than conventional solar panels, meaning that an investment in a SunPower solar energy system pays off significantly more in the long run.
In addition, SunPower panels maintain their energy production much better than conventional panels in partially shaded conditions, making them a better rooftop solar option for customers who live in a cloudy region or an often shady area.
In addition to being highly efficient, SunPower panels are uniquely attractive and aesthetically pleasing. While many other companies in the solar industry offer conventional solar panels — traditional blue photovoltaic panels with bright, visible frames and mounting hardware — SunPower's panels are all black, and their mounting system sleek and nearly invisible, allowing the SunPower solar installation to blend in better with the rooftop on most homes.
SunPower recently introduced SunVault™ storage — a powerful and sleek residential storage solution that pairs with SunPower Equinox®, the company’s premier residential solar power system. Once widely available, SunPower panels that are installed with SunVault storage will allow customers to have ready access to electricity even in the event of a power outage.
Monitoring of system status and performance is extremely important for customers who want to see how much energy the panels on their roof are producing —currently, as well as historically — and ensure that everything is operating as it should.
SunPower provides a helpful, convenient app for customers to do just that. The app provides important system information such as power output, estimated savings, energy production over time, and the environmental impact of the energy generated by the system. All of this system information is easily viewed on a smartphone.
SunPower systems also include a consumption monitoring kit, which is installed if the homeowner’s site is compatible. With consumption monitoring, homeowners can view current and historical energy usage, and the SunPower app provides more in-depth information about their energy profile.
SunPower offers multiple warranties to protect its customers' solar energy systems, including a 25-year Complete Confidence product warranty, which covers the equipment itself, and a 25-year workmanship warranty, which covers the labor and solar installation. The clean energy company also offers a 25-year performance warranty, which covers the customer in the event that their solar modules underperform in terms of energy production and output.
Many customers may be interested in obtaining a SunPower module through a Power Purchase Agreement (PPA) because this payment method typically includes some kind of $0 down option, which eliminates a barrier to entry for them to go solar.
Unfortunately, SunPower only offers PPAs to commercial customers; however, the company's solar lease option can provide immediate financial benefits (and at a flat rate) to customers.
Some users on our site have provided negative feedback with regard to SunPower's customer service. Common complaints include difficulty to reach a representative, delays in returning phone calls and inability to resolve issues.

The best product out there, no sub contractors, installers who work for the company, products made in the USA and even with financing and the monthly payments we are still way ahead at the end of the month. The program works just like promised.
Efficient handling of installation and great online interface.
Friendly knowledgable sales staff. Installers delivered quality product as promised.
Best quality panels, excellent advice, excellent installation.
Excellent Customer Service. Very knowledgeable about the product.
Sun power has reduced my electricity bill by far!
The system works flawlessly with the grid and the battery system.
Equipment seems to work well and they are recommended by installers we trust. Their app to track production is weak and needs improvement.
Pr' -installation tech, not the best. Long period waiting not knowing what was going on. 6 months process end to end
Happy with working with them. Always get a quick response when we notify them. The people we've talked to are very kind and knowledgeable. Tha app is easy to understand.
Prompt honest and thorough. I would recomend them and I would use them again.
The process was explained and carried out perfectly
Customer service and their product follow through and follow up. The price was good as well as the financing.
Quality of work in regards to appearance on roof to the clean install using the breaker panel for monitoring
Quality product and great customer service
Overall excellence in their customer service and products used.
Good, not great. Had problems with monthly report. Took very long time for response, and it was pretty useless reason.
Great customer service, quality install, high quality components.
Efficient service and high quality product.
Most efficient panels resulted in a smaller roof footprint
panels efficiency and supports (questions vs answers)
Great product great service, I had a problem with the panels and they were out and had it fixed within three days
My Supplier HES worked directly with Sun Power
Great product and service. Supplier was HES
Everything went as expected and the installers were consciences
Great production from latest panels - Stellar did very professional installation - Best Warranty
Performance, professionalism, quality of employees.
I have been very pleased with the technical support the few times I needed it and our salesman, Kenny R has been just great in follow-up, monitoring, analyzing, and reporting on our progress for a system that has only been fully in place since December 2019.
great product, warranty, service. I wouldn't go to anyone else
What I was presented as being , the savings has not been the reality. It taken the Team , SEVERAL TIMES to get the , roof pictures and measurements to the Factory . Project completion went way past the , Quoted completion DATES. The Phone numbers for the original , local Company NO longer exist.
I am happy with the work they did and the product they provided.
We had 18 panels installed 6 1/2 years ago and just had 6 more panels added . Great product.
Harness the power of Sun
Very Solar Installation company, the whole process easy and professionally handled.
sunpower has not performed any maintenance as promised by the salesman , i am a 74year old disabled senior and have had their system for one year, and it has not perfoemed as promised. they have not been cleaned,and are creating a fire hazard on my roof . we were sold the cleaning,and bird stop if needed.
Answered all my questions. Promosied to get back to me with a timeline for upgrade.
We were sold on Sunpower product and installation. I would now change my recommendation due to poor service. We had an appointment to fix our solar on Feb 21. That was only after two hours of begging to the service center in the Philippines. We had already waited a month to even get scheduled! Unfortunately, the scheduler cancelled our appointment to reschedule us in April! Are you kidding me?? Our house is up for sale and this is not a good sales pitch for sun power! We have not been able to talk to a supervisor or anyone of authority. So frustrating.

Sunpower has NOT lived up to their hype. I've had my system down more than it's been up. I've had it repaired numerous times and this time I'm currently in the 3rd week of the 3rd month of the system not producing what it's supposed to be capable of. Not only am I paying Sunpower for their system but I'm also paying the electric company ...basically doubling my electric bills . I've called numerous times only to hear "the technical team is monitoring your system". Customer service is horrible as well as the tech team can't seem to fix anything.

I did research and believed that the sun power equipment was very good. I also found that service from most solar companies was not as good as I would like. After talking to the sales person I felt confident that service should not be a problem. The sales staff was excellent over all and very knowledgeable. They did mislead me on one item that I caught (so pay attention to EVERY DETAIL) They did make good on the item after several phone calls and emails. The installers that Sun Power hired were very good, and professional. They did not fool around and got the job done on schedule. They were not Sun Power employees. The account manager was a Sun Power employee. I never met her but I did speak to her on the phone early on when she called to introduce herself. She never once called when she was supposed to. She did not answer my calls or emails unless I gave her a status update on the job. Then she would just rewrite what I had just told her and send it back to me. From the completion of the install to start up it took a little over 3 months. I was told the start up was supposed to take 4 to 6 weeks. After about 8 weeks or so I called the electric company and was told that no one from Sun Power had followed up on the start up, so I started working with the electric company. I sent the manager an update. She sent it back to me as my update. It took me 10 days from the time I started working with the electric company to get the meter set. When all was hooked up and ready to turn on the system was working backwards. I system was making electricity but what is was making was showing up as what I was using and what I was using was showing up as what I was making. Many, many calls to the rep with no response. many calls to the service center to find out after quite a few days that they have no one to service my system and can find anyone to service. I tried to get the contact info for my acct. reps boss. That seems to be a well protected secret (get this kind of info before you sign anything). As it turned out the problem was corrected via computer on their end. However the numbers have never been corrected. Please note I had to get this corrected through the sales department. I took some doing to convince them that the system was not right. I have had to call the support team for several other issues and they do try but they have no field service personnel that they can send to fix the system. The latest issue happened on 12-31-19 after the system has been running for 6 months. The app that I use to monitor the system with failed. I called the call center for service. They determined that they will have to send a tech to fix it. a couple of weeks later they told me they can not find anyone that is willing to work for them to fix the system. The app has not worked for over 7 weeks so far. So other than the sales people this company has not given me any support. They have given me a phone number for a repair person that they want to come out to fix the problem but the person is over 200 miles away. He won't return my calls, but that is not unexpected. Would I recommend this company ? No. Was my experience worse than what is described above? Yes!

I had a Sunpower 12 panel system installed in 2016. It was expected to generate 6000 kWh annually. Year 1 was 6500, year 2 was 3500 and year 3 was 2000. Several calls and emails later I am waiting on a technician who is only available in April almost 3 months after. Can someone from SunPower escalate this and help ?

Hello Sam, I'm sorry to hear that your expectations have not been met. Please be expecting a call from a member of our executive specialist team. They will be able to help with your concerns. We appreciate your business and value your feedback.
My new SunPower system has been up and running for a week... My installation and certification went well and I'm pleased with the professionalism of my installer. I can watch my power meter running backward and am extremely pleased with the performance that I am seeing. As the year progresses, the sun's path should be more directly overhead and it appears that the panels will be producing very near what they are spec'd for. On the other hand, I'm surprised by the intermittent behavior of their monitoring application and web site. I'd be interested in hearing from other SunPower owners about your experiences with their monitoring tools. Because my SunPower monitoring system is directly connected to Internet through a high-speed / reliable connection, I expected a much more responsive (real-time) view of the systems output. On a positive note, at the end of the day, all information about the system's performance appears to be present; I can see a graph of exactly what was produced throughout the day...so I'm not missing any information. The responsiveness of the system appears to vary over the course of the day; sometimes the data is presented quickly, other times it can take minutes for the user interface to refresh. What I also see is that the reported data is delayed up to an hour. Is this what others are seeing? Is this the expected behavior? Again, please let me know if others are seeing what I'm seeing or it's just my installation. Thanks ---------------------------------------------------------------------- A digression: As an Embedded Software (IoT) engineer who designs monitoring systems like this for a living...I have seen this type of "intermittent failure under load" behavior before; which includes the unexpected loss and/or corruption of data. If anyone from SunPower is listening... I offer my consulting services to you for free... I know what could likely be causing this and can probably find and fix it for you in a few days. Again, since I own a SunPower system, I want to help. The responsiveness of the monitoring tools should be able to be greatly improved over how they currently work.

Unfortunately I would love to leave good review, but can’t. Panels and system are great, but service sucks. Main company is in Philippines. I always speak to different people. My problem with panels started last May, today is end of January, still not working after 8 visits. Every time they send new people. They don’t know where previous worker stopped. I am really frustrated.
