I have considered solar for my house in the past but every time I look at the economics I decide not to do it. The return on my investment would exceed my remaining lifespan and add nothing to the value of my home. I've decided that solar is for those folks wanting to make a statement with money to burn. That ain't me.
That's fine, it's your decision. My statement was merely that for some people, it's not all about the bottom line, and that spending the extra dough might be worthwhile. I don't have them on my house now, either, but when I have the money to build my own, I am going to make sure to look into alternative energy, especially solar panels (although who knows how much good they'll be up here in MN).
It seems the biggest problem right not is regulation and tax/fees.
Perhaps what needs to happen is laws which make solar panels exempt for ANY homeowners association rules and regulations, put a cap on a permit not to exceed $100.00 across the board, and .... make the cost of the solar panel system come off two years worth of property taxes.
I like the last one best.
