There are actually many solar farms being put up across the land. A few are for individual use (i.e. a farmer with a large operation might need a lot of power for all of his equipment that he uses mainly in the day anyway, especially on sunny days). Some are for small community use (Alabama Power is doing that here and there to get a good PR promotion or two out of it, but no real use for the 20 or so houses each one is supposed to power).
The main ones that are a joke are the ones put up by the utility to put power onto the grid as a whole, often with the stated purpose of replacing a coal plant. What a joke!
