Various stats. Article lead: "Solar photovoltaic (PV) installations in the U.S. topped 4.78 GW in 2013, an increase of 41 percent over 2012, according to the annual market review and outlook published today by the Solar Energy Industries Association (SEIA) and GTM Research. . . ." 4.78 GW is the nameplate capacity. Still, that's a lot. I suppose it is at least as much as a 1 GW nuke. They could do this in Japan for 4 years to replace the Fukushima reactor capacity. They have plenty of rooftops there. In southern Japan this gives you power when you most need it, during peak demand hours. Better than wind in that respect. - Jed
