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 facilities 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, US.

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

These three projects will produce enough renewable solar energy to serve more than 11,200 households a year.

Soitec will start delivery of the CPV systems for the three new solar energy facilities in 2013 and complete in 2014.

The three power purchase contracts are subject to approval by the California Public Utilities Commission.
