Randy, it doesn't work like that. Square foot of living space, ceiling heights, percentage of facade that has glass, glazing quality, insulation values and installation type, appliance efficiencies, lighting type (incandescent, CFL, LED), and a big one: CLIMATE ZONE (Alaska is a little different than Arizona), etc.

An average home where you are is different than an average home in Florida or New York.

It simply isn't a "average solar system cost xxxx" situation.
