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: 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 equipment, enabling customers to be confident that they will have the highest-quality solar products expertly installed on their homes.
In fact, SunPower provides the highest-efficiency solar panels you can buy today. The company's panels’ solar cells are 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.
SunPower's 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 fewer solar panels.
SunPower panels also boast 75 percent more energy per watt than conventional solar panels, meaning that an investment in a SunPower 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 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, blending 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 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.

Hats off to Michael F, great sales rep. - great response time - very knowledgeable. SunPower Eco Solar - great company! They worked efficiently to ensure us that the total system would be completely installed before the end of 2019. Great communication from the office admin. secretary, Colleen. Workers did a great job! They took care of putting away everything and cleaning up all the rubbish too! Installation workers as well as the office staff were so respectful and willing to help with our concerns and questions.

Extremely pleasant experience! I would recommend them to everyone
Quality of work, price and final result.
Only had system one year and have not had to pay one electric bill!
Everyone was professional and there was a plan for each step and we were advised prior to any actions taking place so we understood the process every step of the way.
Everything is working well. Electric bill reflects savings that we were told we'd receive.
Delivered on what they promised, when they promised. Constant contact between project manager and myself kept me in the loop
I interviewed about five different solar companies in Southern California. Sun Power was honest and offered the best product in the industry. I did my homework and they were everything I hoped for. Without question, Sun Power is the best solar company in Southern California
Great solutions and great experience and better than any other option out there
They are great. They help me when I have questions and if I have a problem.
Quality, reputation and excellent service
Good product, good people, competitive pricing.

Great customer service and very honest. Upgraded our original system and are super pleased once again.
Delivered on every promise they made. Friendly and Helpful staff. The Product looks good and has performed great.
I was having trouble accessing my monitoring system. I called SunPower and Sandra answered the call. She was very polite, understanding,professional and knowledgeable. She walked me through the steps to recover my account access.She was very patient with me, as I'm not very knowledgeable of computers. This experience wasn't stressful, it was very pleasant thanks to her. I would hope that if anyone has question or problem that they would be assisted by her.
The company is very responsive when issues arise. Once the work is completed, there is excellent follow- up to ensure the issues have been resolved and the customer (me) is satisfied.
We just moved into a home with solar panels. We took over the lease. I have no idea how to manage my consumption of energy. A very professional woman named Yellow provided me with a great client experience. Yellow was able to explain my electric bill, how the panels work and finally how to use the dashboard to make an educated decision on when I would run all my appliances. Yellow helped to make sure I could understand all of these things and talked with me till I was comfortable in my newly gained knowledge on SunPower solar panels. Yellow, thank you so much for your stellar approach and teaching skills. The education you gave me has put me at ease. You are amazing !!!
California Solar Electric Company, Michael Burnstein

Hello Anonymous poster, we would appreciate an opportunity to address your concerns. Please send us a direct message with your contact information so that we may have an escalation specialist contact you.
They are that good. The work is clean , looks great. Hadn't had it one year yet but so far so good. I have the Sunpower 415 watt system. Panels come with inverter built onto back of panels. Pretty cool to know that i have the same panels that powered the solar plane. To sum it up , Sunpower is just kick ass. The team for installation was from Freedom Solar. Go look them up, then go look at the work they have done. ( MIC drops ) The End
They provided a great product, and did what they said they would do.
The panels work well and I like the phone inerface.
Mary Anne Mueller
I love my solar panels. I am saving big money on my electric bill!
Service has been good just wish we had more panels
