Measuring Wind Speed

Before installing a wind-power generator, measure the wind-power resource at the site. Local weather data will be helpful, but wind is very site-specific based on local terrain, site elevation, wind direction, and any obstructions such as trees or buildings. Average wind speeds should be calculated along with peak wind speeds during storm events. Installing a wind data logger and monitoring site conditions for a year, or for the target season, will yield enough information to predict the amount of power that can be produced by a wind turbine.
