"There's a total of twelve on each side." Ellsworth Kauffman's solar panels are hard to miss. But, he says, so is the money they'll save.
"Last year our highest bill was $39 for the heat in one month."
Kauffman moved into his house five years ago with the solar heating system already in place. Water runs through the panels on the roof and throughout pipes in the floor of the house - heating it from the ground up.
"It's quite easy for there to be a difference, a major difference in the long run." But a system like his is a big investment, $15,000 to $20,000. A price tag big enough to discourage a lot of people from even considering it.
