GOP lawmakers are pushing to repeal a 50-year-old property tax exemption for homes and businesses with solar, arguing that non-solar neighbors are unfairly subsidizing the “extreme minority” who have panels. Critics say that argument is flimsy. In the town of Hudson, for example, the exemption covers just $2.2M out of a $5.1B tax base, meaning repealing it would have almost no effect on anyone’s tax rate.
