Maybe we'll get that solar roof on a volt for cheap yet.A new patents pending solar energy system will soon make it possible to produce electricity at a wholesale cost of 5 cents per kWh (kilowatt hour). This price is competitive with the wholesale cost of producing electricity using fossil fuels and a fraction of the current cost of solar energy.
XCPV (Xtreme Concentrated Photovoltaics), a system that concentrates the equivalent of more than 1,600 times the sun’s energy onto the world’s most efficient solar cells, was announced today by Sunrgi, a solar energy system designer and developer, at the National Energy Marketers Association’s 11th Annual Global Energy Forum in Washington, DC. The technology will enable power companies, businesses, and residents to produce electricity from solar energy at a lower cost than ever before.
