8. Installation Sites For SkyWind NG
............................................................
8.2 Turbulence
To avoid losses caused by turbulence and lengthen the life of your turbine the lowest point of the rotor must be at least 1 m above the highest point of the building. For a flat roof the
tower should have a length of at least 1/3 of the buildings diameter.
Use the following rule of thumb for placing turbines on top of a standard building:
A.
Choose the middle of the roof (for single turbine)
B.
Install the towers 2.5 m to the left and 2.5 m to the right of the buildings center
(for two turbines)
The minimum distance between two turbines is 5 m and must always be kept to ensure a
proper function of the turbines.
Your turbine must nor be installed behind buildings or in the red (turbulent) area above
them. You should keep a distance of at least 2.50 m from edges of the roof.
Turbulence is not only reducing your energy production but also your turbines useful life
time. Buildings can cause severe turbulence which the turbines must be kept away from
by choosing a suitable site.

Not suitable
The turbine must always represent the highest point!
Never install the turbine below the height of a buildings roof or be-
low treetop height.
Stay away from sharp edges, building attics etc.. Try to install the
turbine as high and free as is possible.
Keep the turbine away from eaves, building edges etc.. If the turbine
appears to be wobbly and won´t lock into the wind direction it is hit
by turbulence. Sometimes turbulence can even cause the rotor to
spin backwards. This can cause damage to your turbine and must be
prevented by choosing a proper site.
