Fairfax City Zoning Code

§ 260-23

Solar systems.

[Added 2-14-2017 by Ord. No. 124]
A. 
Purpose and intent.
(1) 
Fairfax ("City") believes it is in the public interest to encourage renewable energy systems that have a positive impact in energy conservation with limited adverse impact on the community. While Fairfax strongly encourages increased energy conservation and improved energy efficiency, the City also finds that increased use of appropriate renewable energy systems will be an important part of improving sustainability.
(2) 
The renewable energy regulations are intended to supplement existing zoning ordinances and land use practices and ensure these systems are appropriately designed, sited, and installed. These regulations are in place to balance the need to improve energy sustainability through increased use of renewable energy systems with concerns for preservation of public health, welfare, and safety, as well as environmental quality, visual and aesthetic values, and existing neighborhood social and ecological stability.
(3) 
The requirements of this section shall apply to all small-scale solar energy systems (residential, commercial, multifamily and condominium).
B. 
Definitions. For the purpose of this section, the following definitions shall apply unless the context clearly indicates or requires a different meaning:
ACTIVE/SOLAR ENERGY EQUIPMENT/SYSTEM
A solar energy system whose primary purpose is to harvest energy by transforming solar energy into another form of energy or transferring heat from a collector to another medium using mechanical, electrical, or chemical means.
BUILDING-INTEGRATED PHOTOVOLTAIC (BIPV) SYSTEMS
A solar energy system that consists of integrating photovoltaic modules into the building structure by replacing typical building material, such as the roof or the façade, and which does not alter the relief of the roof.
FLUSH-MOUNTED SOLAR PANEL
Photovoltaic panels and tiles that are installed flush to the surface of a roof and which cannot be angled or raised.
FREESTANDING OR GROUND-MOUNTED SOLAR ENERGY SYSTEM
A solar energy system that is installed directly in the ground or by means of brackets or poles and is not attached or affixed to an existing structure.
PHOTOVOLTAIC (PV) SYSTEMS
A solar energy system that produces electricity by the use of semiconductor devices called "photovoltaic cells" that generate electricity whenever light strikes them.
QUALIFIED SOLAR INSTALLER
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. 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.
ROOF- OR BUILDING-MOUNTED SOLAR SYSTEM
A solar power system in which solar panels are mounted on top of the structure of a roof either as a flush-mounted system or as modules fixed to frames which can be tilted toward the south at an optimal angle.
SOLAR COLLECTOR
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.
SOLAR ENERGY SYSTEM
A set of devices whose primary purpose is to provide for the collection, storage, and distribution of solar energy for space heating, cooling, electricity generation, or water heating.
SOLAR FARM
A commercial facility that converts sunlight into electricity, whether by photovoltaics (PV), concentrating solar thermal devices (CST), or other conversion technology, for the primary purpose of wholesale sales of generated electricity. A solar farm is the principal land use for the parcel on which it is located.
SOLAR PANEL
A device for the direct conversion of solar energy into electricity.
SOLAR THERMAL SYSTEMS
Solar thermal 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.
C.
