2.2 Building permits and zoning requirements
Building codes and installation requirements may vary greatly depending on state, city and local
townships. Be sure to obtain all required building permits BEFORE beginning the installation.
Be sure you understand all the installation and inspection requirements. Many localities require
inspections at key phases of the installation before next steps can be taken.
! IMPORTANT:
Do not pour concrete before all required permits are obtained, inspections complete
and you are authorized to proceed.
2.3 Siting
The best location to install a wind turbine is often a compromise. Local building restrictions, the height
of surrounding structures, length of power cables and available open area may require the my!Wind to
be installed in a less then optimum location. In general my!Wind will produce more power if installed
on a taller tower. However, towers are expensive so it is important to balance performance to
installation costs, in order to achieve the lowest cost of energy and the quickest payback.
Figure 1
– Optimal location for the turbine
For optimal performance, install my!Wind in such a manner that blade tip at its lowest position is
6.5 m above any surrounding object within a 75 m radius (see Figure 1). For example in case a 10 m
tower is used, there should be no objects in a 75 m radius, as the tip of the 3 m blade is located at
7 m above the ground.
In addition keep in mind where you plan to install the inverter system and gain access to the grid if it
planned to have a grid connected turbine. Lengthy power cables can substantially contribute to the
installation costs and generate higher losses in the energy conversion process. If a long distance is
