I forget what power rating was on the solar systems I looked at awhile back, but they were quite a bit more than that.
Wish I could do a windmill, but several years ago (about 15 or 20) a guy down the road from me put one up. Lot's of people objected to it
Hence the town added to the zoning laws to prevent anyone else from doing the same thing. This in a rural town with plenty of old windmills still standing from the days when they were used to run irrigation pumps
