2. Site & Customer
SkyWind NG turbines must be installed above obstacles that might disrupt a free and
continuous 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 6m height will generate
only 30
-
40% of a turbine mounted at 10m hub height at the same site.
When installed on a rooftop the hub height should be about 1/3 of the buildings height
or width (whatever is greater) above the building.
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.
