Calibrated high precision device to measure the irradiance at a plant.
Smart integration into Solar-Log web portal - thereby recording of the energy efficiency of a PV plant (direct comparison of PV plants with a pyranometer).
Measurement of weather data such as temperature, wind speed, wind direction, humidity and air pressure. This provides information on the influence of weather conditions on the performance of a PV plant.
Another Company - Meteocontrol GmbH, also uses the compact weather stations WS501-UMB and WS600-UMB with their PV monitoring.
