Yup,

Here in Maryland, without gov't incentives (federal, state, county) and RECs (which is really a state gov't requirement on the utilities), my simple payback period (without any financing/opportunity costs factored in) would be in the vicinity of 25 years (for a 5kw, $18k rooftop system generating 5500 kwh annually with 13 cents electricity cost). I think I could obtain better return than 4% on my capital elsewhere (although I do realize it would increase my home value, so isn't exactly a fair comparison).

It does protect the roof underneath. And when I expanded the array on my "off grid" island home in the San Juans of Washington State I designed the array to be easy to move when the roof needs to be replaced.

When I talked to the local Co. appraiser he said it does add to the value of the home when sold. Sometimes even a premium over the cost.

Leasing is a good option now.

Would You Rather Own or Lease Your Rooftop Solar?

Personally I'd rather own the system. The payback is much faster.
