High Concentration PhotoVoltaic Thermal (HCPVT)

A cutting-edge solar system that resembles a 10-meter-high sunflower has just been unveiled by IBM Research and Swiss solar technology company Airlight Energy. The High Concentration PhotoVoltaic Thermal (HCPVT) system can concentrate the sun’s radiation 2,000 times and convert 80 percent of it into useful energy, generating up to 12 kilowatts of electrical power and 20 kilowatts of heat on a sunny day—enough to power several average homes. It can also produce clean, fresh water as a result of the process used to cool the solar cells. (Video)
