While traveling through the Nevada desert on Hwy 50 (the "loneliest highway in the US") we came across Cold Strings Station, which is a motel, RV park, and general store -- it is located about 50 miles from anything. We were amazed to see a huge solar PV installation. The owner said that it is a 30 KW grid tied solar PV installation that sells excess power to the utility. The owners installed the solar PV as an investment, and feel that it has paid well -- they intend to install additional PV in the future.
The pictures show some of the details of the rack mounted PV panels, with some interesting construction detail.
