Historic districts matter here
The Litchfield historic district, established in 1959, was the first in Connecticut (historicdistrictsct.org). Towns with local historic districts on lhdct.org: Bethlehem, Colebrook, Harwinton, Kent, Litchfield, New Hartford, Norfolk, Roxbury, Salisbury, Sharon, Washington, Watertown and Woodbury.
In a district a commission reviews exterior changes. A local district commission can set design conditions on solar but may not deny it unless the system cannot be installed without substantially impairing the historic character and appearance of the district (C.G.S. §7-147f). SunPol checks your address against these districts during design.
