General Considerations

The location and height of the mounting pole or tower for your wind turbine will be the
major factor in the overall performance of your system.
The smooth flow of wind over land and water is often interrupted by a multitude of
obstructions causing wind sheer and turbulence.
Wind sheer describes the interference between the fast moving upper air and the slow
moving air close to the ground and the resulting decrease in average wind speed as
one gets closer to the ground.
Turbulence is caused by the wind passing over obstructions such as moored boats,
trees and buildings.
Both wind sheer and turbulence diminish with height and can be overcome simply by
putting the turbine sufficiently high above them. It is therefore essential that the wind
generator should be located in an area as free as possible from disturbed wind flow.
Bear in mind that downwind obstructions can be as detrimental to performance as
upwind obstructions (Fig.6).
