(Source: Business Wire)Aerojet, a GenCorp (NYSE:GY) company and Solar Power, Inc. ("SPI")(OTCBB:SOPW), announced jointly today that the companies have entered into agreement to add an additional 2.4 megawatts to the single-axis tracker photovoltaic solar system currently installed at Aerojet's Sacramento, California site. Construction of the 3.6 megawatt solar system at Aerojet's facility was initiated in June of 2009. By expanding the system to six megawatts, the installation will be the largest single-site industrial location in California and one of the largest in the country. The site is located within the Sacramento Municipal Utility District (SMUD).

The announcement of an additional 2.4 megawatts was made during today's dedication event and press conference hosted by Aerojet, SPI and SMUD. The event was held at the same location where California Governor Arnold Schwarzenegger signed an executive order on Sept. 15, 2009 calling for 33 percent of energy consumed in California to come from renewable resources by the year 2020. Heralding the expansion of the solar array, Governor Schwarzenegger said, "The addition of this large-scale solar project is further evidence that reliable, renewable and pollution-free technology is here to stay. And this project is great news for California because it will help us meet our ambitious renewable energy and environmental goals, lead to more homes and businesses powered by sunshine and create new jobs in the clean-tech industry."

"We like to say ˜At Aerojet, it really is rocket science," said Scott Neish, president of Aerojet. "For sixty years, energy management has been at the root of our aerospace operations, and our venture into broader energy management programs demonstrates the real commitment Aerojet is making towards operating in a more sustainable fashion and reducing our company's carbon footprint. This solar partnership is a concrete example of this commitment."

The solar array at Aerojet is a ground-mounted system utilizing a single-axis tracking system that follows the sun's course throughout the day to maximize electricity production. The additional array will utilize 11,712 SPI 205 watt modules mounted atop eight tracking arrays. When completed, the entire six megawatt system will cover more than 40 acres of the Aerojet site and utilize 22 tracking arrays and 29,344 SPI 205 watt photovoltaic modules. Based on its performance characteristics, the SPI 205 watt module is currently the number one ranked PV solar module in its class with the California Energy Commission.

"Prior to this addition, the Aerojet project was already one of the largest system installations in the U.S.
