SunPower® X-Series Solar Panels

Performance, Reliability and Aesthetics

Our top-of-the-line solar panels give homeowners more energy.1 They deliver the highest efficiency available in the residential solar market today.2

  • 1. Most energy per rated watt compared to the top ten solar manufacturers (9 of the top 10 manufacturers were tested, based on Photon Consulting 2013, silicon module shipments). Photon International, 2012 and 2014.
  • 2. Highest of over 3,200 silicon solar panels, Photon Module Survey, Feb 2014.
X Series Solar Panel
SunPower solar panels produce the most energy over the system’s lifetime

Advantages

  • More energy from less space: SunPower® X-Series solar panels deliver 38% more power per panel.1 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.
     
  • More electricity: Simply put, SunPower X-Series panels produce more power than conventional panels. They convert more sunlight to electricity, producing 70% more energy per square foot over the first 25 years.2,3,4
     
  • More 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.
     
  • More peace of mind: More guaranteed power. SunPower offers the best power, product and service 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.
     
  • More beautiful: X-Series panels are available in SunPower® Signature™ Black, designed to blend harmoniously into your roof. Built using all-black solar cells and anti-reflective glass to reduce glare, the premium aesthetics can accommodate a variety of architectural styles.
