Energize CT developed a model solar PV zoning ordinance to aid municipalities in developing their own solar PV zoning ordinance. The model provides example height restrictions for various types of solar collector units. It states that ground-mounted solar PV systems are permitted as an accessory use in all zoning districts upon issuance of the proper permit and that they must not exceed thirty-five inches in height. Roof-mounted solar PV systems (permitted as an accessory use in all zoning districts upon issuance of the proper permit) shall be exempt from height restrictions pertaining to the principal structure so that the height of the system does not contribute to the total height of the principal structure. Building-Integrated PV Systems that are integrated into the roof or the faces of a structure, and which do not alter the relief of the roof, are permitted outright in all zoning districts. The model also provides model setback requirements for solar systems. Roof-mounted systems are exempt from zoning setbacks but may be subject to roof setbacks specific to solar PV in the State of Connecticut Building Code. Such systems will not extend beyond the edges of the roof on which they are mounted. Ground-mounted systems are exempt from front, rear and side lot setback.
