Automated sensor operation systems

Sensors to measure solar irradiance are operated outdoor and therefore subject to various soiling sources such as dust, snow or rain. Many measurement sites are built at remote locations where recalibration of sensors is difficult and and operator service missions are lengthy and costly. We developed a system that operates the sensor in such a way that soiling is significantly reduced and the measurement station has the possibility to recalibrate the sensors without operator interaction, as well as recognize and communicate possible errors in the measurements.
