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.

The X-22 is designed for durability, using the SunPower Maxeon Solar Cell—the only cell built on a solid copper foundation.
