Purchase, Lease, PPA, and Loan Options Available

SunPower provides several flexible purchasing options to make solar energy affordable and accessible for homeowners, including cash purchase, financing, and leasing or Power Purchase Agreements (PPAs). Each option is designed to meet different financial goals while helping customers save money and reduce their carbon footprint.

A cash purchase offers the best long-term value for those who can afford the upfront investment. Homeowners who pay in full own their system outright and can take advantage of federal and state solar incentives, including the Investment Tax Credit (ITC). Without loan or lease payments, all energy savings go directly toward reducing utility costs, and the system can also increase property value.

For those who prefer to spread out costs, solar financing provides ownership benefits with lower upfront expenses. SunPower’s financing options typically offer low- or no-money-down plans with flexible terms. Homeowners can still qualify for tax incentives and start saving on electricity immediately, though interest payments slightly reduce total lifetime savings compared to a full cash purchase.

SunPower’s lease and PPA options are ideal for customers seeking solar savings without ownership responsibilities. With these plans, SunPower retains system ownership and handles maintenance, while homeowners pay a predictable monthly fee or a per-kilowatt-hour rate—usually less than their current utility costs. This approach requires little to no upfront payment and delivers instant savings, though homeowners don’t qualify for tax incentives or added home value.

In short, SunPower’s purchasing options give homeowners flexibility—whether they want to invest upfront for maximum returns, finance over time, or enjoy immediate savings with a hassle-free lease. Each choice delivers dependable solar performance backed by SunPower’s trusted quality and service.

SunPower Solar Panels

SunPower has been a leader in the solar industry for 15 years. SunPower provides high quality solar systems with components that are designed to work seamlessly together. Each component of the SunPower home solar system is rigorously tested to their high standards to provide customers an optimal solar experience. From part qualifications and vendor verification to extended reliability testing (beyond requirements by the International Electrotechnical Commission), these comprehensive quality standards help ensure that their panels will perform for years to come. 

SunPower Solar Panel Energy Production

SunPower offers the industry’s leading efficient panel which boasts up to 22.8 percent efficiency. This means that SunPower panels can provide more clean power for its customers’ homes with less roof space and fewer panels than other companies to meet their energy goals.

Aesthetics Options

SunPower offers front-contact and back contact solar panels. SunPower’s front contact solar panels are designed for higher efficiency and reliability than back contact solar panels due to an extra layer that enables some of the sun’s light to be reflected back into the solar cell.  SunPower’s high performance back contact solar panels feature a copper backing that adds durability to the panel and leaves more room on the front to capture the maximum amount of sunlight.

SunPower is known for the aesthetic appearance of its solar installations due to its InvisiMount® mounting system that helps solar panels appear sleek and nearly invisible. Through this mounting system, SunPower solar installations blend in better with the rooftop on most homes.

Solar Monitoring with Panel Level Data

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 offers its clients a helpful and convenient app through Enphase. 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. Systems equipped with microinverters can view the performance of the solar system at the individual panel level with accessible panel level data, allowing homeowners to understand how system performance is impacted by weather, shading or panel angle. All of this system information is easily viewed on a smartphone.

SunPower Solar Warranties

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. Customers who go solar through a lease or PPA are covered by a warranty for the duration of their lease/PPA term, which includes a performance guarantee for production.

Main Issues Cited in Negative Customer Reviews

SunPower has set the standard for the solar industry in terms of quality of equipment, system performance, flexible financing, and competitive warranties. For these reasons, the company has earned nearly 3,000 five-star reviews from Best Company reviewers. That said, the company's negative reviews reveal certain areas in which SunPower could improve:

• Customer service — approximately 17 percent of negative reviews cite customer service and the main source of their complaint. Difficulty getting in touch with the correct service department and not receiving prompt, helpful responses caused the most friction among these customers.
• Monitoring/billing issues — about 15 percent of negative reviews mention monitoring and/or billing issues affecting their opinion of SunPower. These issues often stem from rare system glitches that lead to customers receiving a higher than expected true-up statement from their utility provider.
