SunPower E-Series Solar Panel

High Performance, Excellent Durability

SunPower® E-Series solar panels deliver efficient performance and long-lasting durability at a great value. Compared to other technologies, SunPower converts the greatest percentage of sunlight into electricity. This means that over the lifetime of your system, you’ll generate more electricity and save more money on your electricity bills.

Advantages

  • More energy from less space: SunPower E-Series solar panels convert more sunlight into electricity than conventional panels, delivering 36% more power per panel.1
  • More electricity: SunPower E-Series residential solar panels convert more sunlight to electricity over the life of your system than conventional panels. Which means you produce 60% more energy over 25 years and save more on your electricity bills, too.23
  • More flexibility: Because E-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 combined power and product warranty over 25 years.4
  • The panels are designed to deliver consistent, trouble-free energy over a very long lifetime.56
  • 1. All comparisons are SPR-E20-327 vs. a representative conventional panel: 240W, approx. 1.6 m², 15% efficiency.
  • 2. Typically 7-9% more energy per watt, BEW/DNV Engineering “SunPower Yield Report,”Jan 2013.
  • 3. SunPower 0.25%/yr degradation vs. 1.0%/yr conv. panel. Campeau, Z. et al.“SunPower Module Degradation Rate,” SunPower white paper, Feb 2013; Jordan, Dirk “SunPower Test Report,” NREL, Oct 2012.
