Soitec CPV chosen by the city of San Diego to supply electricity to over 100 000 homes.
In early 2011, Soitec signed five contracts (now approved by the CPUC) with San Diego Gas & Electric ("SDG&E") to provide a combined total of 155 MW of CPV solar generated electricity. In total, these projects will produce enough renewable solar energy to serve more than 60,000 households a year.
Additionally, a power purchase agreement for up to 150 MW for the Imperial Solar Energy Center West project, another project that currently proposes to use Soitec's CPV technology, was also approved by the CPUC on December 15. Tenaska Solar Ventures, LLC, an affiliate of independent energy company Tenaska, is developing that project.The additional 150 MW makes it capable of supplying the electricity needs of approximately 55,000 homes.
This is why Soitec has made the decision to open a new factory in the San Diego area to manufacture its CPV Modules locally.
Additionally Soitec and Reflexite Energy Solutions Inc., a U.S.-based global supplier of microstructured optical components for the solar power, lighting, instrumentation and display industries, have entered a joint venture called Reflexite Soitec Optical Technology LLC. The new company will produce the silicone-on-glass (SOG) Fresnel lens plates used in Soitec’s concentrator photovoltaic (CPV) modules and co-develop next-generation technologies that will continue to increase the efficiencies and lower the costs of SOG lens plates. The joint venture will be located within the new CPV manufacturing facility.
New Product Configuration Delivers Higher Efficiency and Lower Cost of Electricity
Soitec will be producing in San Diego its fifth generation of concentrator photovoltaic (CPV) modules with enhanced features and performance characteristics specifically designed to benefit large-scale utility power plants.
Soitec's new fifth generation CPV system includes a 28 kW tracker of over 100 square-meters of module area (consisting of 12 CPV modules, each generating more than 2 kW of peak power), the optimum size to deliver high performance while drastically reducing the cost of installation and maintenance. It is designed to improve the Levelized Cost of Electricity (LCoE) for very large solar power plants. While employing the same proven, reliable materials as the previous generation, the new system’s configuration improves upon Soitec’s previous CPV products, boosting energy-generating efficiencies as high as 30 percent by introducing evolutionary improvements to Soitec’s Concentrix™ technology.
Soitec's two-axis-tracking CPV systems are well suited for installation sites with high direct solar radiation. The systems produce a high, constant power output curve throughout the day and are able to match peak-load demands.
