If it's the same NC town I think it is, the issue stems from how much solar they already have. Three sides of the town are bordered by huge solar farms. This one would have locked the town in and given them no room to expand.
IDK man the summary seems to disagree on the mains
A North Carolina town rejected the further installation of solar panels; some residents registered fears that the panels would disrupt the local ecosystem, while many others worried property values would be affected.
I saw what you are referring to, and I'm choosing to believe (to save my braincells, I know its probably wrong) that she was worried about products used in cleaning the panels or ground leaching of chemicals used in the maintenance or manufacture of the panels.
