Actually, the question of satellite dish has come up before, and after some research I found that even though our by-laws state we cannot put antennae or a dish, it is illegal to deny anyone access to communication. I was stunned by the regulation but dutifully followed it....What we can regulate is if wiring is sloppily done or haphazard placement of a dish...
However solar panels do not fall into this category....I too have wanted to place solar electric and water panels...several styles of houses in our neighborhood are perfectly suited for this with long sloping roofs and water heaters in the 2nd floor...I fully support going green, I even have a mulch pile (dutifully hidden) that is helping my garden and yard.....
