Greentech Lead America: SunPower, a global solar energy and technology provider, has introduced its SunPower X-Series Solar Panels (X-Series) for the residential market that offers 21.5 percent efficiency.
The X-Series delivers more energy, higher reliability and superior aesthetics than conventional solar panels. The new world-record efficiency of this product line has received third-party validation by the National Renewable Energy Laboratory (NREL).
The X-Series is made with SunPower’s third-generation Maxeon solar cells which are built on a solid copper foundation for high reliability and performance.
This foundation makes them virtually impervious to the corrosion and cracking that typically degrade conventional panels. As a result, SunPower solar panels are backed by the industry’s first combined 25-year product and power warranty.
“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. Today, we are proud to announce the world-record efficiency X-Series product line,” said SunPower CEO Tom Werner.
The X-Series delivers approximately 8 to 10 percent more energy per watt when compared with conventional solar panels. It yields high energy output with no light induced degradation. It produces low temperature coefficient, allowing for more electricity generation on hot rooftops
The X-Series surpasses the performance of the SunPower E-Series Solar Panels, which placed first, second and third in the 2012 testing conducted by third-party Photon International Magazine for its annual field performance test.
The additional energy generated, along with the high efficiency and reliability delivered by the X-Series, results in approximately 75 percent more energy production over the first 25 years, when compared to a conventional solar system covering the same sized roof.
With the sleek appearance of a jet-black glass panel with a black frame and all-back contact solar cells, the SunPower Signature Black design allows the panels to blend seamlessly into the rooftop.
The new X-Series is now available in a 250 watt small format and a 345 watt standard size format for the residential market, and can be ordered in the U.S. via SunPower’s North American dealer network. The X-Series will be available in Europe later this month.
