X-21 345 WATT PANEL
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.
