TOWER SELECTION AND INSTALLATION
Tower Selecon
Soil and wind condions vary; towers and tower foundaons must be designed
for your specic locaon.
Wind speed increases with height. Higher towers also raise generators above
the air turbulence that can exist close to the ground.
Calculaons are based on Power Law Exponent 0.02 (in areas of tall row crops,
hedges, a few trees.)
Wind Speed
Prevent tower climbing by unauthorized
persons or children. Never climb with-
out proper safety equipment.
Always stop the blades before climbing the tower.
Both falling from the tower and contact with the
spinning blades can be lethal.

THE POWER OF THE WIND: Cube of Wind Speed
The wind speed is extremely important for the
amount of energy a wind turbine can convert to elec-
tricity: The energy content of the wind varies with the
cube (the third power) of the average wind speed,
e.g. if the wind speed is twice as high it contains 2
cubed = 2 x 2 x 2 = eight mes as much energy.
Wind Power Equaon (air density):
WIND POWER = 1/2 x Air Density x Wind Velocity^3 x
