The average cost of installing a rooftop photovoltaic (PV) system on a typical U.S. home is currently about $6.50 per watt ($32,500 for a 5-kilowatt system). Most of the investment flowing into the solar industry these days is targeted toward innovations that can lower that cost. The U.S. Department of Energy (DOE) Sunshot Initiative, for example, recently doled out $145 million in funding for projects that will make PV cost-competitive. A team of scientists and engineers from GE Global Research, the technology development arm of General Electric (GE), was awarded $5.9 million in the latest round of DOE grants, and says its projects can cut the cost of rooftop PV down to $3 per watt...
