Mariemont City Zoning Code

SOLAR ENERGY

SYSTEMS

§ 151.115 PURPOSE.

   It is the purpose of this chapter to regulate the construction, modification, operation and abandonment by discontinuation of use of solar energy systems, subject to reasonable conditions that will protect the public health, safety, and welfare while preserving the enjoyment of private property, promoting orderly land use, and development, allowing the safe, effective, and efficient use of solar energy systems. Solar energy systems shall be considered a permitted use in any zoning district, subject to the requirements of any other applicable chapter of this code.
(Ord. O-3-22, passed 2-28-2022)

§ 151.116 DEFINITIONS.

   For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
   ABANDONMENT. Choosing to give up or discontinue use of the solar energy generation system in whole or part.
   ALTERNATING-CURRENT (AC) MODULE. A complete, environmentally protected unit consisting of solar cells, optics, inverter, and other components, exclusive of tracker, designed to generate AC power when exposed to sunlight.
   APPLICANT. The person or entity filing an application under this subchapter.
   ARRAY. A mechanically integrated assembly of modules or panels with a support structure and foundation, tracker, and other components, as required, to form a direct-current power producing unit.
   FACILITY OWNER. The entity or entities having equity interest in the solar energy facility, including their respective successors and assigns.
   GROUND MOUNT. A solar electrical system that is mounted directly to ground-mounted structure instead of solely on a structure roof.
   OPERATOR. The entity responsible for the day-to-day operation and maintenance of the solar energy system.
   SOLAR CELL. The basic photovoltaic device that generates electricity when exposed to light.
   SOLAR ENERGY SYSTEM (ACTIVE OR PASSIVE). The equipment, assembly or building construction and requisite hardware that provides and is used for collecting, transferring, converting, storing, or using incident solar energy for water heating, space heating, cooling, generating electricity, or other applications that would otherwise require the use of a conventional source of energy such as petroleum products, natural gas, manufactured gas, or electricity produced from a nonrenewable resource. Such systems include passive solar energy systems that capture the sun's energy in building design and construction components; solar thermal energy systems that convert sunlight to heat as in a hot water tank or swimming pool; and photovoltaic solar energy systems that convert sunlight to electricity.
   SOLAR PANEL. One of any type of assembly that produces energy, either electrical, heat or hot water for use or distribution include PV (photovoltaic) an electrical device consisting of an array of connected solar cells, heat collectors and interstitial spaces including trombe panels, solar shingles, or hydronic panels for water heating systems.
   SOLAR PHOTOVOLTAIC SYSTEMS. The total components and subsystems that, in combination convert solar energy into electrical energy suitable for connection to utilization load.

§ 151.117 APPLICABILITY.

   (A)   No person shall construct, erect, maintain, extend, or remove a solar energy system in any zoning district in the village without compliance with the provisions of this chapter and applicable related requirements of the entire ordinances.
   (B)   Solar energy systems constructed prior to the effective date of this subchapter shall not be required to meet the requirements of this code, unless any physical condition or modification renders such system unrepairable or un-useable. If any pre-existing solar energy system is destroyed or damaged to such extent that it cannot be returned to original service, or any such damage or modification creates an unsafe condition it shall be replaced or removed in conformity with this chapter.
(Ord. O-3-22, passed 2-28-2022)

§ 151.118 CONTENTS OF APPLICATION.

   (A)   Solar equipment shall only be an accessory use in residential and business zoning districts. Solar panels are a use permitted by right at any residential or non-residential building. In non-residential districts, solar equipment, other than solar panels, may be located on the roof in compliance with all requirements of this code.
   (B)   An application for a solar energy system shall be approved in compliance with the standards and criteria of this subchapter and shall include:

"Physically remove" shall include, but not be limited to (not applicable to solar shingles themselves):
      (1)   Removal of the solar energy system and related above grade structures.
      (2)   Restoration of the location of the solar energy system to its natural condition, except that any landscaping, grading may remain in the after-conditions.
   (C)   In the event that an applicant fails to give such notice, the system shall be considered abandoned or discontinued if the system is out-of-service for a continuous six-month period. After 12 months of inoperability, the Building Department shall issue a notice of violation to the owner of the solar energy system. The owner shall have the right to respond to the notice of violation within 30 days from receipt. The Building Department shall withdraw the notice of abandonment and notify the owner that the notice has been withdrawn if the owner provides information that demonstrates the solar energy system has not been abandoned.
   (D)   If the owner fails to respond to the notice of violation or if after review by the Building Department it is determined that the solar energy system has been abandoned or use discontinued, the owner of the solar energy system shall remove the system at the owner's sole expense within 60 days of receipt of the notice of violation.
