SDG&E Installing Pyron Solar System

Bruce V. Bigelow10/23/09

San Diego Gas & Electric, a public utility operated by San Diego-based Sempra Energy (NYSE: SRE), says it is planning an 18-month field demonstration of a solar power system that floats in a shallow pool of water. When operational later this year, the 20-kilowatt system developed by San Diego’s Pyron Solar is expected to generate electricity at higher efficiencies and lower costs than conventional flat-panel photovoltaic systems. Pyron’s technology uses a dual-tracking system and acrylic lenses and to concentrate the sun’s energy on a proprietary glass optic. Pyron says its system could produce nearly twice the electricity of conventional flat-panel photovoltaic systems.
