Solar energy systems, fuel cells and the aboveground portion of closed loop geothermal systems shall be treated as accessory buildings which must comply with the requirements of §
177-20E except as further specified in Subsection
C(3)(b)[2] of this section.
All transmission lines from solar energy systems, fuel cells and closed loop geothermal systems to any other building or structure shall be located underground to the extent feasible. This requirement shall not apply to transmission lines owned or managed by any public utility company.
All solar energy systems, fuel cells and closed loop geothermal systems shall be installed according to manufacturer specifications, the requirements of any applicable utility company interconnect agreements and any applicable codes including, without limitation, the Connecticut Building Code.
Where the system is designed to generate electricity, clearly visible warning signs concerning voltage shall be placed at the base of all pad-mounted transformers and substations or fence.
In addition to the requirements of Subsection
C(1), solar energy systems shall be subject to the following additional requirements:
(a) The system must be designed to avoid glare or reflection onto adjacent properties and adjacent roadways and shall not interfere with traffic or create a safety hazard.
(b) Height limitations:
[1] The highest point of a roof-mounted solar energy system shall not exceed the maximum height limitation for the building upon which it is mounted or two feet above the roof of the building to which it is attached, whichever height is lower, except:
[a] On buildings with flat roofs which are located in multifamily residential, commercial or industrial zones, a roof-mounted solar energy system may extend up to 10 feet above the roof of the building upon which it is installed, provided that the solar energy system shall be set back from the perimeter of the roof by a distance equal to one foot for each one foot in height less the height of any parapet wall at the perimeter of the roof; or
[b] Where a main use is subject to special use permit approval pursuant to §
177-42A, an applicant may seek such approval for installation of a roof-mounted solar energy system extending up to 10 feet above the roof of the building upon which it is installed.
[2] Where permitted, ground-mounted solar energy systems shall not exceed 10 feet in height. In residential zones, ground-mounted solar energy systems shall not cover more than 10% of the area of the required rear yard in which the system is to be located, except that where a main use is subject to special use permit approval pursuant to §
177-42A, an applicant may seek such approval for installation of a ground- or pole-mounted solar energy system extending up to the maximum height permitted for main buildings in the zone. Height shall be measured at the highest point on the system. Where components of the solar energy system track the sun's movement across the sky, the height shall be measured relative to the system's most vertical position. Ground-mounted solar energy systems shall also be subject to the following limitations:

(c) Building-integrated systems are deemed to be a component of the structure into which they are integrated and are subject to the requirements of this chapter which otherwise apply to the structure itself.
(d) The surface area of ground and pole-mounted solar energy systems, regardless of mounted angle, shall be calculated as part of the maximum lot coverage of all buildings.
(e) Solar energy systems shall be maintained in good working order at all times. If a solar energy system ceases to perform its originally intended function for more than six consecutive months, the property owner shall promptly remove the collector, mount and associated equipment except where it is in the process of being repaired or is out of service pending the completion of other ongoing work at the property.
(f) The owner of a property on which a solar energy system is installed and/or the owner(s) of the solar energy system itself assume(s) all risk associated with diminished performance of said system caused by any present or future use of nearby property that may interfere with the system's ability to produce power at its rated capacity, regardless of when that adjacent structure or landscaping is constructed or installed.
In addition to the requirements of Subsection
D(1), solar energy systems shall be subject to the following requirements:
(a) The system must be designed to avoid glare or reflection onto adjacent properties and adjacent roadways and shall not interfere with traffic or create a safety hazard.
(b) Solar energy systems installed as main uses shall not exceed 20 feet in height except that an applicant may seek special use permit approval pursuant to §
177-42A for installation of a solar energy system extending up to the maximum height permitted for main buildings in the zone where there is good cause to increase heights to more than 20 feet. In the case where components of the solar energy system track the sun's movement across the sky, the height shall be measured relative to the system's most vertical position.
(c) The surface area of ground or pole-mounted solar energy systems, regardless of mounted angle, shall be calculated as part of the maximum lot coverage of all buildings.
(d) Solar energy systems which are obsolete or otherwise no longer in use shall be removed completely. For purposes of this subsection, a solar energy system shall be deemed to be no longer in use if it has not been used to generate electricity for a continuous period of six months except where it is in the process of being repaired or is out of service pending the completion of other ongoing work at the property.
(e) The owner of a property onto which a solar energy system is installed and/or the owner(s) of the solar energy system itself assume(s) all risk associated with diminished performance of said system caused by any present or future use of nearby property that may interfere with the system's ability to produce power at its rated capacity, regardless of when that adjacent structure or landscaping is constructed or installed.
Permitted as both a main use and an accessory use.
