Anatomy of the fully integrated system

Impressive Reliabiliy

  • Built on a solid copper foundation that is resistant to corrosion and cell breakage caused by damp heat and temperature swings
  • Design eliminates 86% of the reasons conventional cells fail
  • ⁶. Wohlgemuth, J. “Reliability of PV Systems.” Proceedings of SPIE, 2008.

World Record Setting Efficiency

  • Highest efficiency panels available commercially
  • #1 in independent durability tests and have an expected useful life of 40 years ¹⁰
  • Produced sustainably by the first Cradle to Cradle Certified™ Silver Solar Company
  • ⁷. Green, M. A., et. al. “Solar Cell Efficiency Tables (version 47),” Progress in Photovoltaics, 2015
  • ⁸. Highest of over 3,200 silicon solar panels, Photon Module Survey, Feb 2014.
  • ⁹. Fraunhofer PV Durability Initiative for Solar Modules: Part 2. Photovoltaics International, 2014.
  • ¹⁰. "SunPower Module 40-Year Useful Life" SunPower white paper, May 2015. Useful life is 99 out of 100 panels operating at more than 70% of rated power. All comparisons are SPR-E20-327 vs. a representative conventional panel: 250W, approx. 1.6 m2, 15.3% efficiency.

Keeps Energy Flowing

  • First cable management system built specifically for an integrated commercial solar solution
  • Purpose-built metal clips secure cables and prevent erosion
  • Cables protected by 92% recycled rubber cones and trays¹¹
  • Designed for lifetime durability¹¹
  • ¹¹. a. b. Cable cones and trays are made from 92% recycled rubber and are designed for a 25-year life. Cable clips are made from stainless steel and are also designed and tested for a 25-year life.

Uses Plug-and-Play Connectors

  • Factory-installed electrical connections simplify and speed up installation
  • Reduced wiring virtually eliminates the potential for human error
