I spent quite sometime looking at what solution I can use at my home in IL. What I found out is that I can't basically afford it.
I'm looking into solar water heating at the moment. It's probably the most cost efficient solar solution at present.
I personally do not but a few homes in my town have solar panels on their roofs.
I'm sure they did when they were first installed (a picket sign in their front yard to advertise or something) but I don't see any signs now.You are in IL right? do they have any signs that say who they used?
