The Sunpower 435 watt solar panel is one of the highest efficiency PV modules available today. Powered by Sunpower Maxeon solar cell technology, the E20 series provides conversion efficiencies of up to 20.1%. The E20 435 watt has low voltage temperature coefficient and exceptional low-light performance attributes provide outstanding energy delivery per peak power watt.
Sunpower solar panels are only available for purchase with installation by authorized dealers. They are NOT sold separately.
