  • New Products Deliver Unsurpassed Performance, Reliability and Aesthetics

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.

The X-Series delivers approximately eight to 10 percent more energy per rated watt when compared with conventional solar panels.  Features include:

  • High energy output with no light induced degradation
  • Better low-light and spectral response, generating electricity earlier in the morning and longer in the evening
  • 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.

X-Series joins the SunPower E20 Series Solar Panels, offering customers a choice of high efficiency SunPower products.
