The solar panels used at Ridge Vineyards in Healdsburg, Calif., are designed to complement the buildings architecture.Aided by government incentives, solar electricity in Germany is booming. This installation in the Bavarian town of Guenching is one of three sites that together have been dubbed the largest solar park, capable of generating 10 megawatts.Credit: PowerLight PowerLight, which manufactures solar panels, is developing roofing tiles that can generate electricity. The company hopes to build partnerships with building companies.Credit: PowerLightWith rising electricity prices, traditional silicon-based solar photovoltaic panels are being used more widely. FedEx recently installed nearly 1 megawatt of local power generation at its Oakland, Calif., airport location.Credit: PowerLight  Stirling Engine Systems is building large dishes that concentrate the suns rays to drive a mechanical engine. The company is under contract to build an array of dishes capable of generating 500 megawatts of electricity.Using its research in optics and manufacturing, Xeroxs Palo Alto Research Center is partnering with SolFocus to build glass solar concentrators that rotate during the day to face the sun directly. Over the next two years, about 2 megawatts of power generation from this project are slated to be installed and tested.Credit: Xeroxs Palo Alto Research Center A design of Energy Innovations concentrator shows how light reflects from mirrors close to the ground and shines on a silicon solar cell above, which is cooled by fans. The design concentrates the light 25 times, cutting down on the amount of expensive silicon needed. The mirrors move to follow the sun.Credit: Energy InnovationsEnergy Innovations, an Idealab company, is developing solar concentrators that use mirrors and lenses to intensify the light and generate more electricity from solar panels. The companys Sunflower product is designed specifical
