- Uses the highest grade monocrystalline silicon and Maxeon™ cell technology;
- Durable solar cells built on a solid copper foundation;
- Superior construction prevents corrosion and cracking, common causes of degradation in other panels;
- Built with anti-reflective glass to reduce glare and improve light absorption.
These qualities help the X-21 Series by SunPower set the industry record for the most energy produced by production photovoltaic modules. That’s why the name is X-21, from the original record-breaking 21.5% efficiency produced by these panels. Continued research and development has pushed this factor even further, and now the X-Series offers homeowners nearly 23% efficiency, clearly the best panel that money can buy!
Advantages of the SunPower X-Series:
- Purchase fewer panels! SunPower does more with less, so you need less space for the same amount of energy production.
- Make more electricity! SunPower converts more sunlight into electricity than any other panel, so you can also choose to maximize your energy output for the available space.
- Peace of mind guarantee! With a 25-year warranty, SunPower is unmatched in reliability and satisfaction.
- Save more money! A SunPower system generates 60% more electricity over its 25-year lifespan than other companies’ solar panels.
