On August 16, 2010 a group of four innovative electric vehicles started a journey around the world under the banner of the zero emissions race. Race organizer Louis Palmer, who won the 2008 European Solar Prize and himself circled the globe in his home-built Solar Taxi two years ago, continues to build awareness around the planet about how electricity from the sun can readily power buildings and vehicles.
How would you like to buy a solar electric (photovoltaic) system for your home or business, and cut the payback time almost in half? PV/T (photovoltaic thermal) systems may offer a way to improve solar payback times by capturing the waste heat energy from the Photovoltaic (PV) system for your building’s water and space heating needs. Of the sun’s energy that falls on the PV modules, about 15% is converted to useful electricity, which leaves 85% of the sun’s energy available as heat. This excess heating of the PV module is wasted and also decreases PV module efficiency.
