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.

Great All Around
Excellent product and customer service all the way around.
Poor online monitoring tool. It's mostly not functional. Useless.
They installed my solar system on time without issue. They kept me informed every step of the installation. My garage opener didn't work after the instalation and SunPower paid to repair it.
They have all the answers to my questions and they were on time.

Efficient, professional, personable, and prompt
The best panels from the best company, the installers from Ambrose were very professional throughout the process.
No problems with the system and the cost savings for electricity are great
They need different size panels to better use available areas.
Good product but not good customer service and terrible customer service on the financing part of our deal.

Highest panel wattage in the industry, highest quality inverters and an excellent warranty
The panels are the best, they perform as advertised
installed & online quickly. Sleek, efficient panels. Good app for tracking power usage.
The whole process was stress free. We were informed every step of the way.
Great service, from sales to installation.
Only solar panels my installer would use; 25 year warranty.
I chose SunPower for my residential solar system because they make long-lasting, high-quality panels with the best efficiency rating in the industry. I also like their integrated approach to system design, in which they manufacture and use all of their own components.
Their representatives, follow-ups and prompt responses to questions are admirable.
My chat experience yesterday was terrible. I started 6th in line and it took hours to get through.
personnel very professional, knowledgeable, excellent follow up and support.
Great product, looks better than other solar systems in the neighborhood.
I have had my solar panels for 6 years and my solar panels stopped working. I rent my panels from SunPower who provides all the maintenance and operation on them. SunPower sent out a third party contractor who diagnosed the problem as a defective power inverter. The contractor said that it should take should take about two weeks to get the parts and a day to replace the inverter. It has been three months and my power inverter still has not been repaired. I have called both SunPower and the third party contractor numerous times to get a status update and each one blames the other for the delay. UPDATE: Parts were finally received by the contractor to make the repairs (after more than two months since the contractor informed SunPower of the problem). However, I strongly believe that if I had not made repeated calls to SunPower concerning my problem, nothing would have been done.

Please expect a call from an Executive Support Specialist to discuss your concerns in detail and provide additional assistance. We appreciate your business and truly value your feedback
Excellent installation. Excellent products that exceed promised production. Yet digital web sites for billing and monitoring that are in serious need of upgrading.
Great product, almost great service. We had to call them a couple of times to get an update on our project. I felt like if we had not done that, the install would have taken longer. They were very receptive to our concerns and made it right immediately. I would work with them again.
Top of the line panels that are very advanced technology wise
They were very easy to work, upfront about costs and timelines, they handled all the permits and coordination with the electrical company, as well as help me apply for a State grant
They were timely and did everything they said they would
So far, I am very pleased with my solar panel choice and everything is working as it should.
Great product, great performance, great company!
Awesome service, quick installation, flexible schedule
Great customer service and fast, convenient
I did research and SunPower Panels seemed to be better than all the other panels we looked at. The Install Team were above our expectations. We had heard so many other people going Solar that were disappointed about the installation but we could not be happier.ptions were brilliant
I am super pleased about the panels I have. Sunpower panels and Enphase Energy micro inverters are an unbeatable combination. I feel at ease knowing my panels are covered for any issues whatsoever as long as I own them. Feels good to be on the renewable energy bandwagon. :)
Excelent product and warrenty. Their installer (Green Logic) was outstanding.
good product, great installation service
They did a great job, they keep me updated on what was going on and got the job done in time.
Sunpower has an awesome product and excellent customer service. Highly recommend Esmay Electric for installation.
Great quality solar panels so far! Haven't had them up too long, but so far are very efficient
Knowledgeable sales people representing a superior product.
Only getting 4 stars because it hasn't been long enough for 5. Can't really rate because it's only been 3 (winter) months. I have already recommended you twice.
Quick, positive response. Pey and his staff went out of their way to ensure I was happy.
The overseas call center masquerading as "customer service" is a joke. Once you get somebody here in the US, they are a surprisingly efficient and knowledgeable company. Getting that far may take months though, so only 4 stars from me. I would definitely recommend SunPower to friends and family and have in the past. Unfortunately the incompetent "customer service" forces me to take a star away. Get rid of this and they are a 5+ star company.
