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.

Brian Mac Donald
They have been very helpful and crew was very professional and I really liked there work. They were on time and quickly got job done. I would recommend SunPower to my friends.
Great service- so good they are very busy which caused a longer wait than desired
Great product, and great service. The solar panels look fantastic on my roof, and they were installed crazy fast.
Highly efficient with fewer panels than my neighbors.
Good product, efficient installation and service, no problems.
Very efficient and cortecios personal I will recommend to any one
I had the worst experience ever with sun power solar installation in the end of 2011. They subcontracted out the installation to people that were not qualified and bro 24 of my cement roof tiles which they never made good on. I planned on buying the system in the early buyout option .Sunpower would never take care of the broken roof tile issue prior to this date and then screwed me out of the early buyout option.I even sent a certified letter for which they tried to say they did not receive. Then I sent them an email. When your customer service is in the Philippines and you’re trying to deal with issues they don’t care at all. This has never been resolved today and I am still looking for an attorney to sue them.

very happy customer
Great staff, wonderful sales person, enjoyed the proffessional friendly staff.
The system is working well so far. I am awaiting my rebate check.
Panels are working well -- and when I had a question on monitoring, I received a call back within an hour
Product quality and company professionalism
It's been online for a very short period of time, that makes it harder to evaluate.
Good price, good quality, good warranty, the system was installed quickly and works great. Was up and running within two days
Great product. Great service! The installation was smooth as was all the associated admin!
No problems with any of the equipment at any time so far
Terance La Croix
They are great people to work with, they never pressure you to buy their product.
They are a bit high in cleaning solar panels.
Sunpower was in my top 3 to choose. They were not the least expensive, but their total package of product quality, warranty, and service made them my choice. The salesperson was very knowledgeable and made me confident in my choice. The Installation was not very good though. There was a lack of communication and expectation setting. Also little collaboration.
Outstanding experience from the beginning until the end
Easy contract process. Fast, efficient installation. Great performance, ie production exceeds estimates.
So far we're producing about twice the energy we're using
Good units but not enough panels for our needs
good ,fast and reliable, good quality equipmment
I have a constant failed connection in order to monitor my panels production online, despite router change and switching internet providers
A satisfied customer
SunPower's team has been professional and courteous every step along the way.
good company, good people and good products
SunPower's customer service is genuine and effective
Great solar panels, great value!
Definitely the best solar panels on the market. When I am making a large investment for solar panels, I want to make sure they have the best warranty, and are the most efficient. SunPower definitely hits the mark with the product and the warranty.
John from Babylon
Great process from start to finish. Up front and honest. My system looks and performs better than expected.
Good product & service; productivity of the panels so far seems excellent
Sunpower had my 86 year old grandfather sign a 20-year lease. He died 4 years later and now this lease is the responsibility of his next of kin. Predatory? Beware of this company.

Piece of crap company. Once getting my load controller installed I had to turn it on and off to be able to have my dryer work. This was before the system was activated. Then I had to turn the controller off to have heat, hot water, dryer, stove working in my house. I had to pay for an internet upgrade and now having to look into pest control issues with pigeons and mites because the company wants me to now pay for bird netting through them or I void my warranty.

I checked the first PG&E bill after installed and calculated. ROI is less than 10 years which I was told before installation.
Wade Bischoff, Nicole Corona, Kassy Macias

Excellent high performance panels.They perform better then the other manufacturers i am familiar with.
excellent customer service and follow-up throughout the process, professional installers but never received final review of system once it was installed
Excellent & efficient staff. Very helpful through entire process
Everything from start to finish was as promised. They deserve 10 stars
Jon in Lemon Grove
Efficient, one-stop shopping with great products
Easy to deal with and provide a quality product.
Best panel available - most power produced and looses least amount of production over time.
