Siting The Windcharger
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 trees and
buildings.
Both wind sheer and turbulence diminish with height and can be overcome
simply by putting the machine sufficiently high above them as shown.
Wind speed decreases and turbulence increases where obstructions exist.
Consider also that downwind obstructions can be as detrimental to performance
as upwind obstructions.
