Quick Answer
Small wind turbines work best in locations with consistent, moderate wind speeds, typically above 5-7 mph (8-11 km/h). Ideal locations include open areas away from trees, buildings, and other obstacles that can disrupt airflow. A minimum distance of 50 feet (15 meters) from the turbine to the nearest obstruction is recommended.
Choosing the Right Location
When selecting a location for a small wind turbine, consider the topography and local climate. For example, areas with prevailing westerly or northwesterly winds are often ideal, as these wind directions are more consistent and stronger. In the United States, the National Renewable Energy Laboratory (NREL) recommends evaluating wind speeds using a mapping tool, such as the Wind Atlas, to determine the best locations for small wind turbines.
Turbine Placement Techniques
To optimize turbine placement, consider the following techniques: First, install a temporary anemometer (wind speed sensor) at the proposed turbine location to measure wind speeds over a period of time. Next, use a wind direction vane to determine the prevailing wind direction. Lastly, use a wind rose diagram to visualize the wind patterns and identify the best orientation for the turbine.
Obstacle Considerations
When placing a small wind turbine, it’s essential to consider nearby obstacles that can disrupt airflow and reduce turbine efficiency. Common obstacles include trees, buildings, power lines, and hills. To mitigate these effects, consider the following: Maintain a minimum distance of 50 feet (15 meters) between the turbine and any obstruction. Use a wind turbine with a wide rotor diameter to capture wind energy more efficiently. Consider installing a smaller turbine to reduce the impact of obstacles on turbine performance.
