SOLAR ENERGY SYSTEMS

Sec. 30-1581. - Purpose and intent.

The town finds that the development of solar energy systems should be balanced with the protection of the public health, safety and welfare of the public. The town resolves that the following standards shall be adopted to ensure that solar energy systems and solar energy farms can be constructed within the town while protecting public safety and the natural resources of the town. The town finds that it is in the public interest to encourage the use and development of renewable energy systems that enhance energy conservation efforts but result in limited adverse impact on nearby properties. As such, the town supports the use of solar energy collection systems and the development of solar energy farms.

(Ord. No. 175, § 1(812.01(subd. 1)), 3-26-2019)

Sec. 30-1582. - Applicability.

These regulations shall apply to all solar energy systems and solar energy farms on properties and structures under the jurisdiction of the town.

(Ord. No. 175, § 1(812.01(subd. 3)), 3-26-2019)

Sec. 30-1583. - Definitions.

The following words, terms and phrases, when used in this article, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning:

Accessory solar energy system means a system which is roof or building mounted, or architecturally integrated, or ground-mounted panels which are located on a lot or parcel with a principal use such as a residence or business designed to supply energy for onsite residential use; excess energy produced may be sold back to the grid through net metering or commercial use to generate energy to offset utility costs or as an additional revenue stream.

Building- or other architecturally-integrated solar energy system means an active solar energy system that is an integral part of a principal or accessory building, rather than a separate mechanical device, replacing or substituting for an architectural or structural component of the building. Building-integrated systems include, but are not limited to, photovoltaic or thermal solar systems that are contained within roofing materials, windows, skylights and awnings.

Community solar energy system (CSES) or solar garden means a solar-electric (photovoltaic) array that provides retail electric power (or a financial proxy for retail power) to multiple community members or businesses residing on site or located off-site from the location of the solar energy system. A CSES is not a solar energy system that has been primarily designed for export to the wholesale market. A CSES may be connected to the electrical transmission grid in order to sell excess power to the utility company. A CSES is a solar energy system that has a capacity of no more than one megawatt of power. All solar energy systems that are primarily designed for export to the wholesale market, regardless of megawatt capacity or land area, shall be regulated as a solar farm.

Ground-mounted panels means freestanding solar panels mounted to the ground by use of stabilizers or similar apparatus. Ground-mounted panels may be systems which are accessory to the principal use of the site and designed to supply energy for the principal use (see also Accessory solar energy system) or may be part of solar garden (CSES) or solar farm operation.

Photovoltaic system means an active solar energy system that converts solar energy directly into electricity.

Right-of-way means those lands designated and delineated to contain a public or private roadway, bicycle path, walking trail, recreational trail, or other mode of ground transportation.

Roof- or building-mounted solar energy system means a solar energy system that is mounted to the roof or building using brackets, stands or other apparatus. Typically, accessory to the principal land use, these may also be used in solar gardens (CSES).

Solar array means a group of solar panels wired together.

Solar collector means a device, structure or a part of a device or structure that the principal purpose is to transform solar radiant energy into thermal, mechanical, chemical or electrical energy.

Solar energy means radiant energy received from the sun that can be collected in the form of heat or light by a solar collector.

Solar energy system (SES) means an active solar energy system that collects or stores solar energy and transforms solar energy into another form of energy or transfers heat from a collector to another medium using mechanical, electrical, thermal or chemical means.

Solar farm means a utility scale commercial facility that converts sunlight into electricity, whether by photovoltaics (PV), concentrating solar thermal devices (CST), or other conversion technology, where the principal purpose of land is to provide energy to off-site uses or wholesale sales of generated electricity.

Solar hot water system means a system that includes a solar collector and a heat exchanger that heats or preheats water for building heating systems or other hot water needs.

(Ord. No. 175, § 1(812.01(subd. 4)), 3-26-2019)
