Using more or larger wire will also increase your installation cost. A substantial amount of electricity can be lost as a result of the wire resistance-the longer the wire run, the more electricity is lost. Whether the system is stand-alone or grid-connected, you also will need to take the length of the wire run between the turbine and the load (house, batteries, water pumps, etc.) into consideration. If your tower is guyed, you must allow room for the guy wires. When siting be sure to leave enough room to raise and lower the tower for maintenance. System Considerations - It is encouraged that you only consider small wind turbines that have been tested and certified to national performance and safety standards.Your turbine needs to be sited upwind of any buildings and trees, and it needs to be 30 feet above anything within 300 feet. You also need to plan for future obstructions, such as new buildings or trees that have not reached their full height. In addition to measuring or finding out about the annual wind speeds, you need to know about the prevailing directions of the wind at your site. In addition to geological formations, you need to consider existing obstacles, such as trees, houses, and sheds. You can have varied wind resources within the same property. If you site your wind turbine on the top of or on the windy side of a hill, for example, you will have more access to prevailing winds than in a gully or on the leeward (sheltered) side of a hill on the same property. Wind Resource Considerations - If you live in complex terrain, take care in selecting the installation site.Some general considerations they will discuss with you include: Your professional installer should help you finding the best location for your wind system.
