Solar Power, Inc. ("SPI") (OTCBB:SOPW) announced today that it will host a luncheon on Tuesday, November 10, 2009 from 11:00 AM to 1:45 PM in Sacramento, California to provide industry analysts and investors with a corporate update presentation and Q&A session with SPI CEO and Chairman, Mr. Stephen Kircher. Additionally, an overview presentation on the Aerojet project will be given by Mr. Eric Hafter, President of SPI's Commercial Construction Division. At 3.5 megawatts, covering more than 20 acres of Aerojet land, the system is one of the largest single-site industrial solar installations in the United States.

Immediately following the luncheon, SPI and Aerojet will jointly host a dedication ceremony and press conference at the site and unveil a permanent monument and visitation center for the installation site. The system is a major part of Aerojet's environmental and sustainability initiative. "The Aerojet project, which has been one of the largest system installations in the U.S. this year, is the foundation of our growing portfolio of multi-megawatt projects," said Mr. Kircher. "More importantly, the project has been successful for us and our client. Our team has executed the project on time, on target and on budget. I couldn't be more pleased with the results," Mr. Kircher concluded.

During its first year of use, SPI's Aerojet system is expected to offset approximately 4,200 tons of carbon dioxide, 16.7 tons of sulfur dioxide, and approximately 6.5 tons of nitrogen oxide that would have otherwise been produced using fossil fuel power production. The first-year net clean energy benefits equate to offsetting approximately 8,270,000 automobile miles driven or the clean air benefits realized from planting 976,520 trees. With a system life expectancy of 25 years, the cumulative life-cycle environmental offsets for a system of this scope are significant.

Analysts and prospective investors interested in attending the luncheon and ceremony should contact Brion Tanous with CleanTech IR at (310) 541-6824.
