San Diego Gas & Electric (SDG&E) and subsidiaries of Soitec Solar Development have signed three contracts with a combined capacity of 30MW of solar energy.

The electricity will be generated at three solar power plant sites in San Diego County that will use Soitec Concentrix technology.

The concentrator photovoltaic (CPV) modules will be manufactured in a new Soitec factory to be built in the San Diego area.

The company said that these three projects will produce enough renewable solar energy to serve more than 11,200 households a year and further contribute to SDG&E reaching its RPS goals.

The projects will deploy ground-mounted dual-axis tracking CPV solar power system, which uses lenses to concentrate sunlight onto very small, extremely efficient solar cells which convert the light into electrical energy.

Soitec will implement capacity investments and pursue options for related financing to construct its San Diego area factory.

Soitec’s delivery of the CPV systems for these three new solar energy facilities in San Diego County will begin in 2013 and finish in 2014.
