PARC solar concentrators
Using its research in optics and manufacturing, Xerox's 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.
Stirling Engine Systems is building large dishes that concentrate the sun's rays to drive a mechanical engine. The company is under contract to build an array of dishes capable of generating 500 megawatts of electricity.
With 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.
