UNMATCHED PERFORMANCE, RELIABILITY & AESTHETICS

HIGHEST EFFICIENCY 6

Generate more energy per square footGenerate more energy per square footGenerate more energy per square footGenerate more energy per square foot

X-Series residential panels convert more sunlight to electricity producing 44% more power per panel,1 and 75% more energy per square foot over 25 years.3,4

HIGHEST ENERGY PRODUCTION 7

Produce more energy per rated wattProduce more energy per rated wattProduce more energy per rated wattProduce more energy per rated watt

High year one performance delivers 8-10% more energy per rated watt.3

This advantage increases over time, producing 21% more energy over the first 25 years to meet your needs.4
