No overhead costs, only underfoot costs, as we'll still need to pump the water out of our well.
When I was about 15, in the mid 70's, my Dad (a conservative mid-west farmboy) uncharacteristically surprised everyone by having solar panels put on our roof. We were the talk of the town. Even with 3 teenage girls we always had sufficient hot water, and muchly reduced electric bills.
