PowerLight's World's Largest Solar Power System Completes First Year of Operation

"The performance of the 10 MW Bavaria Solarpark has been very strong," noted Janine Schellhorn, Chief Managing Director of Deutsche Structured Finance (DSF). "Based on the consistent performance of this groundbreaking solar installation, we look forward to working with PowerLight and our other partners to develop additional large-scale systems at other sites throughout Europe."

"PowerLight is pleased to report that our solar power system -featuring our patented solar tracking technology- is reliably producing clean renewable energy," said PowerLight's CEO Tom Dinwoodie. "The scale and quick success of this deployment validates the market leadership of our PowerTracker system."

"Good planning and system design, high quality components and careful monitoring have resulted in the terrific yield that is being realized by this milestone solar power system - now, and for decades to come," added Mr. Klaus Kiefer of the Fraunhofer Institute of Solar Energy Systems, which is involved in the monitoring and quality control of the installations.

Bavaria Solarpark was designed and provided by PowerLight Corporation, using its patented PowerLight PowerTracker system. This innovative tracking system follows the sun as it moves across the sky throughout the day, producing more electricity than conventional fixed systems. PowerTracker's single-axis design is optimized to be reliable, cost-effective and efficient, thereby optimizing project economics. With 6.3MW of solar PV in Muehlhausen and 1.9MW each in Guenching and Minihof, Bavaria Solarpark is comprised of a total of 57,600 photovoltaic panels.

PowerLight served as the turnkey solar power system provider, leading the project's development, design, deployment, and service. The photovoltaic modules were produced by Sharp Electronics. Siemens AG provided electrical construction and equipment, such as inverters. The solar power plant was built on fallow fields formerly used for agricultural purposes. The area provides ecological benefits; herds of Moorland sheep graze the pastures and keep the grass short under the solar electric panels and extensive vegetation areas were planted to enhance the integration of the project site into the surroundings.

Bavaria Solarpark was financed by Deutsche Structured Finance and the Solar Energy Fund Bavaria, a closed fund.
Together with PowerLight and Siemens, regional companies K&S Consulting, Max Boegl Group and Klebl GmbH worked on the development and construction of the solar parks.

All three solar power plants began producing clean energy during 2004. Interconnection to the electrical grid was secured by the regional German utility E.ON Bayern and E.ON Netz. The German EEG guarantees a 20-year power purchase for electricity produced from renewable energy sources.

The world's largest photovoltaic system further validates Germany's forward-looking energy policies. Bavaria Solarpark -and similar projects like it- reinforce Germany's leadership in deploying renewable energy. "During its anticipated lifetime -at least 20 years- the solar systems of Bavaria Solarpark will produce hundreds of millions of kilowatt hours of clean electricity," noted Dinwoodie. "At a time of rising energy prices and concerns for our environment's health, PowerLight is working with the industry's most respected companies to deliver clean, renewable energy."
