Illinois WestChicago Siemens factories have completed the upgrade, to begin production of photovoltaic inverters. Siemens has invested about $ 10 million to the two plants into this upgrade, which one will be used to support the rapid growth of the U.S. solar power market.

Currently, Siemens is located WestChicago SINVERTPVS photovoltaic wind turbine inverter being produced for the U.S. Southwest 20ME use solar power plants. Early 2011, Siemens has made this multi-million dollar contract. Under the agreement, Siemens will be delivered in October this year before all products.

Siemens Energy and Automation division vice president RajBatra AMD, said: "For Siemens, today is a proud day, because we are located WestChicago plant will continue to maintain its leading position in the solar industry, and further as the new U.S. energy markets provide efficient products we manufacture in the United States has gradually inverter will this work by the blue-collar jobs to green collar shift. "

Siemens WestChicago plant consists of two plants constitute an area of ​​200,000 square feet, 350 employees.
