There are a few things to consider when choosing a Wind Turbine to supplement your power requirements:

• If you are living in a Town or City – Check with your local city council first before installing a turbine to make sure they allow them in your area.
• Check your existing solar system – Check the size; type and voltage of your battery system, to make sure it’ll match the voltage produced by the turbine you are interested in. Most of the time the wind controller can be ordered to match your existing system voltage.
• Where to put your new turbine? – Do you have the free air space to put up a turbine without it being in turbulent air? i.e., 6 meters up and above and trees and buildings and ideally 100M away from any structure, to get clean laminar airflow and peak performance.
• Know the average wind speed in your area (Online info for your area here) – If you are in a low wind speed area, you may need a five-blade turbine.
