The planet´s most powerful solar panel.

The SunPowerTM 320 Solar Panel provides today’s highest efficiency

and performance. Utilizing 96 back-contact solar cells, the SunPower

320 delivers a total panel conversion efficiency of 19.6%. The 320

panel’s reduced voltage-temperature coefficient, anti-reflective glass and

exceptional low-light performance attributes provide outstanding energy

delivery per peak power watt.

BENEFITS

Highest EfficiencySunPowerTM Solar Panels are the most efficient photovoltaic panels on the market today.

More PowerOur 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 CostMore power per panel means fewer panels per install. This saves both time and money.

Reliable and Robust DesignProven materials, tempered front glass, and a sturdy anodized frame allow panel to operate reliably in multiple mounting configurations.
