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.
