The ideal position for a wind generator is a flat open space with good wind from at least one direction (known as the prevailing wind
direction), a coastline, or a smooth hill top with an open area in the prevailing wind. The wind speeds up significantly near the top of
the hill and the air flow should be reasonably smooth and free from excessive turbulence.
Excessive turbulence or “bad wind” causes fatigue damage and shortens a generator’s working life. When siting, keep away from local
obstructions such as large trees and houses, or use a taller tower to ensure that the generator is well above the obstructions. Wind
speed also increases with height so it is best to have the generator as high as your zoning laws and investment payback will allow. It is
recommended to site you generator at least 20 feet (6 m) above any surrounding obstacles such as trees or buildings in a 250 foot (76
m) radius (see general siting image above).
