Quick Answer
Assessing wind speed on your property involves installing an anemometer, a device that measures wind speed, in a location that represents the average wind conditions. The anemometer typically records wind speeds over a period of time, and the data is used to determine the average annual wind speed. This data helps determine if your property is suitable for a small wind turbine.
Understanding Wind Speed Requirements
To determine if your property has enough wind for a small wind turbine, consider the following: the American Wind Energy Association recommends a minimum average annual wind speed of 5 meters per second (11 mph) for a small residential wind turbine. In general, wind turbines are most effective in areas with average annual wind speeds of 7-10 meters per second (15-22 mph). If your property’s wind speed is below these levels, a wind turbine may not be a cost-effective option.
Measuring Wind Speed on Your Property
To accurately assess wind speed on your property, install an anemometer at a height of 10-15 meters (33-49 feet) above the ground, which is the typical installation height for a small residential wind turbine. The anemometer should be placed in an open area, free from obstructions such as trees, buildings, and hills. Record wind speeds over a period of at least 6 months to 1 year to get a accurate representation of your property’s wind conditions.
