See what it takes to make the wheel on your utility meter spin backwards! Even when the Hanks family is home, Eric says their rooftop panels cut their energy bill from almost $200 a month to about $35 dollars a month. Installing the system cost about $12,000 once state and federal tax credits were factored in. Eric estimates that they'll recover that investment in about four years even though they live in a place where the skies are often overcast.
