Anemometers are instruments that measure and monitor the wind. They are therefore used for monitoring wind farms and weather stations.
In the photovoltaic field they are installed for uses provided by the standard EVS-EN 61724-1. In PV systems they are installed with solar tracking system, in places where wind is a frequent meteorological factor. This type of systems need to be secured in case of wind gusts that exceed a given threshold perceived by the anemometer.
