E18/230 SOLAR PANEL
18% EFFICIENCY
SunPower’s signature black™ 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 MaxeonTM cell
THE WORLD’S STANDARD FOR SOLAR TM
technology and advanced module
design ensure industry-leading reliability SunPowerTM E18 Solar Panels provide today’s high efficiency and
performance. Powered by SunPower MaxeonTM 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.
