Best TechnologyHeadlines:

• Outperforms, Outlasts, Outshines

The technology behind SunPower® solar is unique—and better—than conventional panels. Designed in the USA, our systems make more electricity from every ray of sunshine, and stand stronger against severe weather conditions. So you get more power and more durability than any other system available today.

SavingsHeadlines:

• SunPower® solar panels make more power for more savings

• Lower your energy bill with the highest efficiency solar panels available1

More power means more savings. SunPower’s unique technology is built-to-last when conventional panels lose power with age. No other solar technology converts more sunlight than SunPower, giving customers an incredible 70 percent more energy in the same space over 25 years,2 resulting in more savings over time.

Headlines:

• More Powerful, More Durable, More Attractive

• Big Power from Small Spaces

• SunPower® solar panels make more power for more savings

• Lower your electricity bill with the highest efficiency solar panels available1

SunPower’s world record-setting high-efficiency panels2 produce more energy than conventional panels,³ which means

customers need fewer panels and less roof space to generate the same amount of energy. The more energy you

generate on your roof, the less you have to buy from the electric company—so even homeowners with smaller roofs can

generate more energy and reduce, or even eliminate, their electric bill.

In addition, SunPower’s panels are uniquely designed to perform better in low light, “waking up” earlier in the morning

and “staying awake” later in the day,⁴ generating energy even when it’s cloudy or foggy outside.

Proven ExperienceHeadlines:

• Seeing the future of energy takes a unique perspective

SunPower has been leading the way in solar for over 30 years. Designed here in the U.S., our systems have been installed on over 500,000 homes around the world. And because we design and manufacture our own products, we can stand behind them with the industry’s best 25-year Combined Power and Product Warranty.

SunPower has powered solar aircrafts for NASA, built the world’s largest solar power plant and teamed up with the San Francisco 49ers on their new, environmentally-friendly Levi’s Stadium. We’ve partnered with household names like FedEx, Toyota, Walmart and more. Even the U.S. Department of Energy turns to us for solar. Only SunPower packs so much know-how into every solar system we make.

Most Customized ExperienceGoing solar is not one-size-fits all. Each home is uniquely suited for solar, ranging from the direction it faces, to the type of roof and the surrounding trees. And each homeowner also has unique needs, from energy goals to financing. SunPower’s local market partners tailor every solar system to the homeowner’s personal needs. From flexible financing solutions including loans or zero-down leases,* to complex installations designed for a tile roof, SunPower has it covered.

* For qualified customers.

Best Local ExperienceSunPower hand picks dealers that share our values of quality and integrity. So homeowners can rely on a SunPower-certified installer in their area to handle all aspects of the installation, while their high efficiency solar system is designed, manufactured and warrantied by a global company that’s been around for 30 years.
