SunPower® E-Series Solar Panels
High Performance and Excellent Durability

SunPower E-Series high-achieving solar panels for homes deliver efficient performance, long-lasting durability at a great value.
 

 
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. 2,3
  • 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.5,6
