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.

Great install team, but not sold on sales
So far my system has exceeded my expectations. Just wish I had the ability to monitor each panel separately.
Excellent product & an outstanding customer service people
Great product, great customer service, even in the time of COVID.
Everything went very smoothly up till Covid. Has been very difficult to have any communication since then.
The equipment and power generated was excellent but the data available to the owner from that equipment is somewhat limited.
The service is working find and my electricity bill is lower.
I think they have the best solar panels available and like that the equipment can be located in the garage.
This is my second house with Sunpower. They used to be great. Now calls go through a foreign call center and repair work is subcontracted. But their original installer can't get their attention either. The microinverters in my 4 year old panels failed in early April. They sent a crew in late May but that crew said they's have to send a different crew with different tools. Now I leave voicemail messages and get the same response: they will contact me when they are ready. Something terrible happened to a formerly good company and I'm ready to go to court.

After 3 week still waiting for my dahboard to work.
There were a few issues and the installers jumped on the problems and fixed them right away.
On time and did what they promised that they would
Quality product and installation team. Office staff did all the necessary work to get permissions from the home owners association and our utility company. The install was scheduled with a timeline indicating several landmarks along the road to completion so we always knew the progress.
The staff were/are very responsive to my questions and make sure we understand what is happening
SunPower is a fantastic company, from the smooth and professional sales process, to their customer communication once the order was placed, and the amazing efficiency and speed in which they were able to install the panels (and all during a pandemic!) I highly recommend this company.

Looks good and great value with an excellent warranty.
Great service to there customers. Easy to work with. Smooth installation.
The panels are ver6 well made excellent life expectancies and very high output
System is proving to provide as much power as promised. However, the inverter sensitivity to Hz fluctuations needs to be more tunable to match Tesla Powerwall feedback conventions.
They have delivered everything they said they would and more. They are a great company to work with.
Very helpful if you have questions, professional in every area.
Quality product, good people and good communication

Happy in San Mateo
Good friendly service. Informative, knowledgeable. Generally like doing business with SunPower.
Excellent performance under low light and at high angles of incidence.
Rising Sun LLC provided awesome service and SunPower products were a part of it all.
I am extremely happy I chose SunPower over the other brands. The installation was quick and painless. The price was about the same and the guarantee is exceptional! I should have gone solar a long time ago.
Professional and timely service. They kept me well informed about all aspects of the process. My only complaint has been in the timeliness in processing my rebate. Over 5 months since project completion, and still no rebate.
