SunPower Celebrates the Dedication of SOLON's Gut Erlasee Solar Park

World's Largest Solar Electric Power Plant Features SunPower's

High-Efficiency A-300 Solar Cells



Sep 01, 2006, 01:00 ET from SunPower Corporation

    SAN JOSE, Calif., Sept 1 /PRNewswire-FirstCall/ -- SunPower Corporation
 (Nasdaq:   SPWR), a Silicon Valley-based manufacturer of the world's highest
 efficiency, commercially available solar cells and solar panels, celebrated
 today's dedication of SOLON's Gut Erlasee Solar Park, the world's largest
 solar electric power plant. This 12 MW solar power plant is located in a
 working agricultural field in Bavaria, near Arnstein, Germany, and will
 fulfill the electrical needs of thousands of local customers each year.
     SunPower's high-efficiency A-300 solar cells are used in SOLON's
 "Mover" electricity generation system, designed for deployment in
 multi-megawatt solar power plants. The movers automatically tilt and rotate
 during the day to directly face the sun at all times. By combining
 SunPower's industry-leading, high-performance solar cells with the Mover's
 ability to maximize daily energy production, each square foot of Mover
 solar panel surface can generate up to double the annual energy of a fixed
 solar array using conventional solar. At Gut Erlasee, SunPower's solar
 cells power about one-third of the Movers but generate a higher proportion
 of the energy at the Solar Park due to their exceptional performance.
     "We are very pleased to be part of today's dedication ceremonies," said
 Peter Aschenbrenner, vice president of sales and marketing, for SunPower
 Corp. "This installation is a testament to SOLON's vision to make solar
 power a mainstream energy source -- in this case providing solar power to
 thousands of customers in a unique and cost-effective way. We are proud
 that our high-efficiency solar cells are powering many of the Movers at Gut
 Erlasee."
     Thomas Krupke, CEO of SOLON AG, added, "Since the start of our
 cooperation last year, SunPower has been an important strategic partner for
 SOLON. By using SunPower's high-efficiency solar cells, we were able to
 increase the energy output of our SOLON movers, while offering the solar
 power market a state of the art product."
