2. Site & Customer
SkyWind NG turbines must be installed above obstacles that might disrupt a free and con-
tinuous airflow. Remember the following rule:
BASIC RULE:
When your head is at the height of the turbines nacelle you must not look into any
trees, houses or other obstacles! You should see the horizon in any direction!
The turbines nacelle should, in any case, be mounted in a height of 10 m above the
ground at least.
BASIC RULE:
The closer a turbine is mounted to the ground, the more energy of the airstream
will be lost due to ground friction. In most cases a turbine installed in 6 m height will generate
only 20
-
40% of a turbine mounted at 10 m hub height at the same site.
When installed on a flat rooftop the hub height should be about 1/3 of the buildings
height or width (whatever is greater) above the building and at least 10 m above ground.
A turbine should be mounted in the middle of a rooftop rather than on its edges.
Individual turbines should be mounted in five (5) meters distance to each other.
