Voltageis a measure of the electric potential difference between two points; usually expressed as volts (V). ground.
Toweris the structure of a wind energy system that supports the rotor and power train, etc., above the
Rotoris the set of blades of the wind turbine including the hub.
Rotor speedis the rate of rotation of a wind turbine rotor about its axis.
Power outputis the amount of power produced by a wind turbine at a given speed.
Rated wind speedis the specified wind speed at which a wind turbine's rated power is achieved.
Rayleigh wind speed distributionis a statistical curve whose shape approximates the actual shape of a wind speed distribution curve. It is used as a standardized distribution curve to estimate the energy production performance of a wind turbine.
Power curveis a graph that depicts the power output of a wind turbine as a function of wind speed.
Mean wind speedis the statistical mean of the instantaneous value of the wind speed averaged over a given time period which can vary from a few seconds to many years.
Hubis the fixture for attaching the blades or blade assembly of a HAWT to the rotor shaft.
Hybrid Systemis a term used to describe an alternative energy system which uses multiple charging sources such as wind, micro hydro generators.
Guy anchoris a foundation designed for guy wire connection.
Guy cableis a cable or wire used as a tension support between a guy anchor and a tower.
Guyed toweris a tower that uses external guy supports
Direct current( DC ) electric current which flows in only one direction in a wire. Our turbines and batteries are DC.
Free standing toweris a tower that does not use external supports, such as guy wires.
Currentis the rate at which electricity flows through a conductor; measured in amps (A).
Cut-in wind speedis the lowest wind speed (at hub height) at which the turbine starts to produce power.
Anemometeris a device used to measure wind speed.
Annual Average Wind Speed (AWS)is the average of all instantaneous wind speeds for a location over the course of a year.
Annual energy output (AEO)is the total energy produced by a wind turbine over the course of a year.
