NLR - SunPower 320W Mono Black Frame Solar Panel


Out of Stock


NOTE: These particular modules were part of a larger inventory we purchased that are classified as "seconds." These should supply identical performance to new modules, though have superficial scratches to either the front laminate or frames, or may display slight discoloration of the backsheets. They are offered "as is", though still carry factory warranty. Limited to supplies on hand.

The planet's most powerful solar panel.

The SunPower 320 Solar Panel provides today’s highest efficiency and performance. Utilising 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.

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 anodised frame allow panel to operate reliably in multiple mounting configurations.
