As used in this article, the following terms shall have the
meanings indicated:
ALTERNATIVE ENERGY
Includes geothermal energy, solar energy and wind energy
sources. Alternative energy sources may at times be referred to as
"renewable energy sources."
BLADE CLEARANCE
Required minimum distance between the lowest point of a rotor
blade and the ground surface below it.
BUILDING-INTEGRATED PHOTOVOLTAIC (BIPV) SYSTEM
A BIPV system forms part of the structure to which it is
affixed. Typically integrated into a roofing system (e.g., solar shingles),
BIPV systems can provide architectural interest and/or an unobtrusive
solar energy system installation.
HORIZONTAL-AXIS WIND TURBINE
A type of wind turbine in which the axis of rotation is parallel
to the ground and the blades are perpendicular to the ground.
INTERCONNECTION
Interfacing an on-site electricity generator to the electric
distribution system (i.e., the grid). This configuration allows an
on-site electricity generating system to operate in parallel with
the grid. For small systems, the point of interconnection is through
a circuit breaker of the main electric service panel on site, or it
could be a supply tap on the service line just before the main electric
service panel.
INTERCONNECTION AGREEMENT
A legal document between a customer and an electric utility
authorizing the connection of the customer's on-site electricity generating
system to the utility's electric grid.
NACELLE
The structure that houses all of the generating components,
gearbox, drive train, etc., of a wind turbine.
NET METERING
An approach for interconnecting and metering on-site electricity
generating facilities; the means of measuring the difference between
electricity supplied by an electric utility, electric distribution
company, or electric generation supplier and the electricity generated
by a customer-generator using alternative energy sources. Net metering
allows customers to use excess on-site generated electricity to offset
utility-purchased electricity on a monthly or annual basis.
NET METERING AGREEMENT
An agreement with a customer-generator and an electric utility,
electric distribution company, or electric generation supplier, regarding
the electricity generated by a customer generator, that allows customers
to receive a credit at the retail price of electricity for surplus
electricity generated on site. Under a net metering agreement, a bidirectional
electric meter is used to measure and record the flow of electricity
in both directions from and to the customer-generator.
POWER PURCHASE AGREEMENT (PPA)
A contract to purchase energy. A PPA is usually established
between a party that generates electricity and a party that purchases
electricity. A PPA may also be a contract written between a building
owner that wants to generate electricity on site and a third-party
developer who will install, maintain and own the system used to generate
the electricity and then sell the electricity produced by the system
to the building owner at a predetermined rate.
ROTOR
The blades and hub assembly of a wind turbine.
ROTOR DIAMETER
The cross-sectional dimension of the circle swept by the
rotating blades.
SHADOW FLICKER
The on-and-off flickering effect of a shadow caused when
the sun passes behind the rotor of a wind turbine.
SOLAR ACCESS
The ability of sunlight to shine on a property owner's land,
or more specifically, the owner's solar energy facility or solar energy
system, without the sunlight being blocked by structures, vegetation,
or other obstructions on neighboring land.
SOLAR EASEMENT
A legal agreement that protects access to sunlight, or solar
access, on a property.
SOLAR ENERGY FACILITY
An alternative energy facility that consists of one or more
ground-mounted, freestanding, or building-integrated solar collection
devices, solar-energy-related equipment and other associated infrastructure
with the primary intention of generating electricity or otherwise
converting solar energy to a different form of energy for primarily
commercial or other off-site use.
SOLAR ENERGY SYSTEM
An alternative energy system that consists of one or more
ground-mounted, freestanding, or building-mounted solar collection
devices and solar-energy-related equipment and other associated infrastructure
with the primary intention of generating electricity or otherwise
converting solar energy to a different form of energy to reduce on-site
consumption of purchased power. When a property upon which the system
is installed also receives electricity supplied by a utility company,
excess electricity generated and not presently needed for on-site
use may be used off site by a utility company.
SOLAR GLARE
The effect produced by light reflecting from a solar panel
with an intensity sufficient to cause annoyance, discomfort, or loss
in visual performance and visibility.
SOLAR HOT-WATER SYSTEM
Uses solar energy to heat water. The most common types of
solar water heaters are evacuated tube collectors and glazed flat-plate
collectors generally used for domestic hot water, and unglazed plastic
collectors used mainly to heat swimming pools.
SOLAR PANEL
A device containing one or more receptive cells equal to
or greater than two square feet, the purpose of which is to convert
solar energy into electrical or thermal energy.
TOTAL EXTENDED HEIGHT
The vertical distance from the ground level to the tip of
a wind generator blade when the tip is at its highest point.
TOWER
A guyed or freestanding structure, anchors, and foundation
that is specifically engineered to support a small wind turbine.
TOWER HEIGHT
The height above grade of the fixed portion of the tower,
excluding the wind turbine itself.
VERTICAL-AXIS WIND TURBINE
A type of wind turbine in which the axis of rotation is perpendicular
to the wind stream and the ground.
WIND ENERGY SYSTEM
Equipment that converts, and then stores or transfers, energy
from the wind into usable forms of energy, which has a rated capacity
of not more than 20 kW and which is intended to primarily reduce on-site
consumption of utility power. This equipment includes any base, blade,
foundation, generator, nacelle, rotor, transformer, vane, wire, inverter,
batteries, or other component of the system.
