A five megawatt (MW) pilot concentrated solar power (CSP) plant designed in SolidWorks 3D CAD software, available from Solidtec Solutions , went online during the first week of October, 2009, providing electricity to 4,000 homes near Los Angeles. California-based eSolar used SolidWorks 3D CAD software to design heliostat mirrors that reflect and concentrate sunlight to a boiler that generates steam and powers a standard turbine to create solar energy.
