What is a hub height?

The hub height is the distance from the turbine platform to the rotor of an installed wind turbine and indicates how high your turbine stands above the ground, not including the length of the turbine blades. Commercial scale turbines (greater than 1MW) are typically installed at 80 m (262 ft) or higher, while small-scale wind turbines (approximately 10kW) are installed on shorter towers. Wind speed increases with height above ground, so to get an accurate assessment you want to choose a hub height that is close to your expected turbine height.
