I would think that a "solar farm" where the end user is making money from the use of their land would be zoned commercial use.
Seems like it's your town or county zoning board you need to address this issue with?
I would think, and I could be wrong, but something like that would be put up for a town / county vote?
Just be nice. My dad was on his local zoning board and he was a pretty good man who used common sense, but listening to him about his experience, seemed everyone was screaming at him LOL
