SunPower has introduced its X-Series solar panels, intended for the residential market, which the company claims delivers unsurpassed levels of efficiency at 21.5 percent. The panels incorporate the company’s third-generation Maxeon solar cells which are built using a copper foundation that makes them virtually impervious to the corrosion and cracking that usually act to degrade conventional solar panels.
“Our research and development teams have been working diligently to surpass the high performance standards set by our SunPower E-Series Solar Panels that are built with our second-generation solar cells” said Tom Werner, SunPower CEO.
The new panels feature high energy output with no light induced degradation, better low light and spectral response and a low temperature coefficient thus allowing for more electricity generation on hot rooftops. They also surpass the company’s E-Series panels which were placed first, second and third in the 2012 field performance test conducted annually by Photon International Magazine. They have a sleek black appearance in order to blend into the rooftop and are available in a 250-watt small format and a 345-watt standard format.
