E20/327 SOLAR PANEL
20% EFFICIENCY
SunPower E20 panels are the highest
efficiency panels on the market today,
providing more power in the same
amount of space
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
technology and advanced module
design ensure industry-leading reliability
THE WORLD’S STANDARD FOR SOLAR
TM
SunPowerTM E20 Solar Panels provide today’s highest efficiency and
performance. Powered by SunPower MaxeonTM cell technology, the E20
series provides panel conversion efficiencies of up to 20.1%. The E20’s
low voltage temperature coefficient, anti-reflective glass and exceptional
low-light performance attributes provide outstanding energy delivery per
peak power watt.
