BTW, if so, please put all the panels in Nevada... solar panels sucking up sun's energy would mean nice temperate summers in Las Vegas. 
Batteries to store the solar power is the other half of the equation in that solar power panels are useless at night. And Tesla is well along on its quest to develop these essential storage devices.

No noise either.
Solar farms kill an awful lot of birds, though. Migrating birds think they're ponds, land on them, and fry.
Wind farms aren't any better.
