Increased Efficiencies, Reduced Costs Expected
SAN DIEGO, Oct. 23, 2009 – San Diego Gas & Electric (SDG&E) today announced it has joined with Pyron Solar of San Diego to test an advanced concentrated solar-power system that floats in a shallow pool of water and is expected to generate electricity at higher efficiencies and lower costs than conventional flat-panel photovoltaic systems. The objective of the 18-month demonstration project is to validate the technology for potential broad commercial applications.
Now being installed at SDG&E’s Mission Control/Skills Training Center in Mission Valley (photo), the technology utilizes acrylic lenses and a dual-tracking system floating in water to concentrate the sun’s rays and focus the sunlight on a proprietary glass optic. The glass optic spreads the sunlight evenly over advanced photovoltaic cells to generate electricity.
