E19 / 318 SOLAR PANEL
MAXIMUM EFFICIENCY AND PERFORMANCE
BENEFITS
Highest Efficiency
SunPowerTM Solar Panels are the most
efficient photovoltaic panels on the
market today.
More Power
Our panels produce more power in
the same amount of space—up to 50%
more than conventional designs and
100% more than thin film solar panels.
Reduced Installation Cost
More power per panel means fewer
panels per install. This saves both time
and money.
Reliable and Robust Design
Proven materials, tempered front glass,
and a sturdy anodized frame allow
panel to operate reliably in multiple
mounting configurations.
The planet´s most powerful solar panel.
The SunPowerTM 318 Solar Panel provides today’s highest efficiency
and performance. Utilizing 96 back-contact solar cells, the SunPower
318 delivers a total panel conversion efficiency of 19.5%. The 318
panel’s reduced voltage-temperature coefficient, anti-reflective glass and
exceptional low-light performance attributes provide outstanding energy
delivery per peak power watt.
