THE WORLD’S STANDARD FOR SOLAR
SunPowerTM E18 Solar Panels provide today’s high efficiency and performance. Powered by SunPower Maxeon cell technology, the E18 series provides panel conversion efficiencies of up to 18.5%. The E18’s low voltage temperature coefficient and exceptional low-light performance attributes provide outstanding energy delivery per peak power watt.
SunPower’s signature blackTM panels provide the highest efficiency for
their product class and a sleek, black appearance.
MAXIMUM SYSTEM OUTPUT
Comprehensive inverter compatibility ensures that customers can pair the highest- efficiency panels with the highest-efficiency inverters, maximizing system output.
REDUCED INSTALLATION COST
More power per panel means fewer panels per install. This saves both time and money.
RELIABLE AND ROBUST DESIGN
SunPower’s unique Maxeon cell technology and advanced module design ensure industry-leading reliability.
