The X-21 335 Watt - super efficient, and ultra durable
X-21 345 Watt Panel
More Efficiency, Lower Electric Bills

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 at a later date.

Our panels guarantee more power and more peace of mind. We also offer the best-combined power and product warranty for 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.

The X-21 345 Watt - The most efficient X-Series Solar Panel
X-22 360 Watt Panel
Most Power, Less Space

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. X-22 panels are 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. X-22 panels rank #1 in the Fraunhofer durability test and have 100% power maintained in the Atlas 25+ comprehensive durability test.
