X-Series Solar Panels

Unmatched Performance, Reliability and Aesthetics

Our top-of-the-line solar panels deliver the highest efficiency available in a residential solar panel today—a record-breaking 22.8%. X-Series residential panels convert more sunlight to electricity. They produce 38% more power per panel and 70% more energy per square foot over 25 years. They also have high year-one performance, and deliver 8-10% more energy per rated watt. This advantage increases over time, producing 21% more energy over the first 25 years to meet your needs. That means homeowners get more electricity, more flexibility, more peace of mind, and lower electricity bills.

Conventional panels Vs. SunPower panels

If you have been delaying your switch to solar because you thought adding solar to your home would detract from its aesthetics, the X-21 335 watt panel is for you. With integrated microinverters, this beauty will blend seamlessly with your roof. SunPower Equinox has 70% fewer visible parts than conventional panels. And with the highest efficiency available, we can reduce the number of total panels needed to meet your energy needs.

X-21 solar panels




Because X-21 345 Watt residential solar panels generate more electricity from a smaller area, you can expand energy production simply by using additional roof space to add more panels later.

Our panels guarantee more power, and more peace of mind. We also offer the best combined power and product warranty over 25 years. And because our panels are built on a solid copper foundation, SunPower solar cells deliver unmatched reliability over the lifetime of your solar energy system.

X-21 345 solar panels




Our X-22 360 watt panels produce the most energy and take up much less space. They boast the highest efficiency available on the market by any manufacturer and deliver 44% more power per panel, which means you can generate more power in smaller spaces, with fewer panels. Simply put, these panels convert more sunlight to electricity, producing 75% more energy per square foot over the first 25 years. The X-22 is designed for durability, using the SunPower Maxeon Solar Cell—the only cell built on a solid copper foundation. These cells make the panels virtually impervious to the corrosion and cracking that degrade conventional panels. The X-22 ranks #1 in Fraunhofer durability test and 100% power maintained in Atlas 25+ comprehensive durability test.
