SunPower Modules Recognized for Superior Quality and Efficiency
Independent Organizations Validate SunPower's Technology Leadership
SAN JOSE, Calif., April 18 /PRNewswire-FirstCall/ -- SunPower Corporation (Nasdaq: SPWR), a Silicon Valley-based manufacturer of high-efficiency, commercially available solar cells, panels and systems, announced today that Sandia National Laboratories measured SunPower's SPR-315 solar panel at the highest recorded conversion efficiency ever tested by Sandia for a commercially available, mass produced solar panel. This announcement follows recent renewable energy industry accolades from PHOTON Magazine and Energy Focus Ltd., (ENF) in the first quarter of 2007, underscoring SunPower's position as the global leader in solar electric technology efficiency, performance and satisfaction.
Sandia National Laboratories, based in Albuquerque, N.M., rated the newly-released SunPower 96-cell solar panel as the most-efficient commercially available, mass-produced panel ever tested at the lab . Sandia measured the actual power output of the SunPower 315 watt nameplate-rated solar panel at 321.65 watts, giving the panel an unprecedented [back-up] module efficiency of 19.7 percent.
PHOTON Magazine's February 2007 "Buyers Market Module Survey" concluded that SunPower holds the efficiency record for solar cells and panels made in series production. SunPower's SPR-315 panels utilize the company's new Gen 2 solar cells, rated at 22 percent conversion efficiency.
ENF published a study that ranked SunPower solar panels the No. 1 photovoltaic brand in the world, owing to a combination of excellent product quality and good value for the money. The ENF study surveyed hundreds of directors of solar photovoltaic installation companies in 45 countries.
