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 315 Solar Panel provides today’s highest efficiency and performance. Utilizing 96 back-contact solar cells, the SunPower 315 delivers a total panel conversion efficiency of 19.3%. The 315 panel’s reduced voltage-temperature coefficient, anti-reflective glass and exceptional low-light performance attributes provide outstanding energy delivery per peak power watt.
