SunPower 300 Watts Grid Connect Solar Panel


The SunPower 300 Solar Panel provides todayÆs highest efficiency and performance. Utilising 96 SunPower all back-contact solar cells, the SunPower 300 delivers a total panel conversion efficiency of 18.4%.


The 300 panelÆs reduced voltage-temperature coefficient and exceptional low-light performance attributes provide outstanding energy delivery per peak power watt


SunPower designs, manufactures and delivers high-performance solar electric technology worldwide. SunPower high-efficiency solar cells generate up to 50 percent more power than conventional solar cells. High-performance solar panels, roof tiles and trackers deliver significantly more energy than competing systems.




Highest Efficiency
Panel efficiency of18.4% is higher than any commercially available panel of similar size.


More Power
SunPower 230 delivers up to 50% more power per unit area than conventional solar panels 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.
