• Most energy from less space: SunPower X-Series solar panels deliver 44% more power per panel.2 Which means you can create more power in smaller spaces, with fewer panels. And, you can position them on the sunniest parts of your roof.
  • Most electricity: Simply put, SunPower X-Series panels produce more electricity than conventional panels. They convert more sunlight to electricity, producing 75% more energy per square foot over the first 25 years.3,4
  • Most flexibility: Because X-Series 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.
  • Most peace of mind: More guaranteed power. SunPower offers the best combined power and product warranty over 25 years. And because they’re built on a solid copper foundation, SunPower solar cells deliver unmatched reliability over the lifetime of your solar energy system.5
