A structure, the use of which is customarily incidental and subordinate to that of the principal building and is attached thereto, and is located on the same lot or premises as the principal building.

Structures, equipment, devices or construction techniques used for the production of heat, light, cooling, electricity or other forms of energy on site and may be attached to or separate from the principal building.

A solar energy power system that consists of integrating photovoltaic modules into the building structure, such as the roof of the facade and which does not alter the relief of the roof.

Solar installations owned collectively through subdivision homeowner associations, college student groups, "adopt-a-solar-panel" programs, or other similar arrangements.

Photovoltaic panels and tiles that are installed flush to the surface of a roof and which cannot be angled or raised.

A solar energy power system that is directly installed in the ground and is not attached or affixed to an existing structure. Pole-mounted solar energy power systems shall be considered freestanding or ground-mounted solar energy power systems for the purposes of this article.

For purposes of this article, the term "large-scale solar" refers to solar photovoltaic systems that produce more than 12 kilowatts per hour of energy or solar-thermal systems which, although it may serve the building or electrical service to which they are attached, provides energy for other buildings, other properties or the commercial electrical grid.

A billing arrangement that allows solar customers to get credit for excess electricity that they generate and deliver back to the grid so that they only pay for their net electricity usage at the end of the month.

A solar energy power system that produces electricity by the use of semiconductor devices, called photovoltaic cells that generate electricity whenever light strikes them.

A person who has skills and knowledge related to the construction and operation of solar electrical equipment and installations and has received safety training on the hazards involved. Persons who are on the list of eligible photovoltaic installers maintained by the New York State Energy Research and Development Authority (NYSERDA), or who are certified as a solar installer by the North American Board of Certified Energy Practitioners (NABCEP), shall be deemed to be qualified solar installers for the purposes of this definition. Persons who are not on NYSERDA's list of eligible installers or NABCEP's list of certified installers may be deemed to be qualified installers if the Town of Mount Hope determines such persons have had adequate training to determine the degree and extent of the hazard and the personal protective equipment and job planning necessary to perform the installation safely. Such training shall include the proper use of special precautionary techniques and personal protective equipment, as well as the skills and techniques necessary to distinguish exposed energized parts from other parts of electrical equipment and to determine the nominal voltage of exposed live parts.

A solar energy power system in which solar panels are mounted on top of the structure of a roof as a flush-mounted power system.

The distance from a front lot line, side lot line or rear lot line of a parcel to any component of a freestanding or ground-mounted solar energy power system, solar facility or solar power plant within which no solar components shall be permitted.

For purposes of this article, the term "small-scale solar" refers to solar photovoltaic systems that produce up to 12 kilowatts per hour of energy or solar-thermal systems which serve only the building or electrical service to which they are attached, and do not provide energy for any other buildings.

Space open to the sun and clear of overhangs or shade including the orientation of streets and lots to the sun so as to permit the use of active and/or passive solar energy power systems on individual properties.

A solar photovoltaic cell, panel, or array, or solar hot air or water collector device, which relies upon solar radiation as an energy source for the generation of electricity or transfer of stored heat.

An easement recorded pursuant to NYS Real Property Law § 335-b, the purpose of which is to secure the right to receive sunlight across real property of another for continued access to sunlight necessary to operate a solar collector.

Solar collectors, controls, energy storage devices, heat pumps, heat exchangers, and other materials, hardware or equipment necessary to the process by which solar radiation is collected, converted into another form of energy, stored, protected from unnecessary dissipation and distributed. Solar power systems include solar thermal, photovoltaic and concentrated solar. For the purposes of this law, a solar energy power system does not include any solar energy power system of four square feet in size or less.

A device for the direct conversion of solar energy into electricity.

Energy generation facility or area of land whose principal use is allowed by special permit issued by the Planning Board to convert solar energy to electricity, whether by photovoltaics, concentrating solar thermal devices or various experimental solar technologies, with the primary purpose of wholesale or retail sales of electricity. No other buildings or uses are required unless needed for the solar installation.

A device that stores energy from the sun and makes it available in an electrical form.

Solar thermal power systems directly heat water or other liquid using sunlight. The heated liquid is used for such purposes as space heating and cooling, domestic hot water, and heating pool water.
