Average Customer Rating

Overall, SunPower earns strong online reviews from customers. For our review, we analyzed customer feedback from Consumer Affairs, Solar Reviews, and Best Company. Among those resources, SunPower averaged 4.06 out of 5.0 across 1,036 reviews.

Positive reviews mention the smooth enrollment and installation process with the professional SunPower team, responsive and knowledgeable customer service and high quality panels.

Negative reviews harp on the confusion around working with third-party technicians and frustrations with faulty inverters.

SunPower Finance Options

SunPower offers three different payment options to choose from: leasing, financing or buying your system outright.

SunPower leases are best for customers who don’t have a lot of money to put down but want to save on energy. Often times, you don’t have to pay anything upfront for your lease. Generally, lease payments are still smaller than utility bills.

SunPower loans are an excellent choice for those who don’t have the $25,000 available but aspire to eventually own their solar system. The loan also allows you to keep any state or federal tax incentives, which will help your system pay for itself faster. If you move, you can sell the system to the new homeowners or include the price in your listing.

If you buy a system outright from SunPower, you’ll have to pay for everything upfront. However, you’ll get big tax incentives, and you can also leverage a home equity loan to make ownership possible.

Solar Equipment

When reviewing SunPower, we were impressed with their innovation and the value they place on solar panel quality. The company designs and manufactures the highest efficiency solar panels on the market.

The flexible panels have an average longevity of 40 years (double the industry standard) and an efficiency rate of 22 percent. According to SunPower, their panels produce 60 percent more energy than comparable panels. With this kind of efficiency, you can pay for your system faster.

And with EnergyLink, the SunPower monitoring system, you can check your energy usage anytime from anywhere with the unique mobile app. This can be a useful tool to see your lifetime savings estimate in real-time.

Size and Configuration

SunPower’s Equinox panels have an efficient and streamlined design which means fewer panels are needed, while discreet Invisimount frames and hidden microinverters are also utilized.

When comparing SunPower’s 6 kW system with its competitors, 6 fewer panels are required. Furthermore, 8 fewer panels are needed for its 8 kW system.

Solar Panel Warranty

SunPower offers a unique, comprehensive “Complete Confidence Warranty” that covers the entire solar system - not just the panels. The warranty covers repair or replacement costs, including workmanship, for 25 years (20 years for leases).

Our favorite feature of SunPower’s warranty is the power output guarantee. For the first 25 years, the company pledges that their installed panels won’t lose more than 8 percent of the original power output, while the industry average is up to 19 percent.

Maintenance & Troubleshooting

Should you need any repairs on your solar system, SunPower will pay to have the damaged panels removed and new ones shipped and installed, with no cost to you. Plus, the company covers rust damage, which is a prevalent problem in high-moisture areas. Receipts, proof of purchase, or written claims are not required.
