Sensor check

Get accurate solar radiation measurement

The irradiance data gathered from satellite imagery are used for the automatic sensor condition based check-up, by detecting sensor failures and possible configuration issues, also generating warnings if discrepancies are found. If the irradiance sensor shows a systematic anomaly behaviour, while a nominal on-site recalibration and/or sensor replacement procedure is not immediately possible, a new corrected irradiance sensor measurements dataset is generated exploiting satellite data (Sensor Statistical Recalibration)Finally, reliable and accurate long-term PV DC effects can be assessed correlating the sensor measurements and the satellite irradiance data.

Drone data management

Get accurate information about PV plant construction and thermal problems


This service aim is twofold: support procurement stage in the acceptance phase and support O&M teams during plant operations. The service is based on the automatic analysis and delivery of insights from IR and visible video of PV plant. The video are collected by i-EM or third parties drones. The sisible spectrum videos allow the acceptance stage to provide accurate detection and count the number of panelspolestrackers and cabin units. The combination of IR images and visible images help the O&M teams during the operational stage exploitign the detection of hotspots and other typical problems of rooftop or ground installation (dirt, delamination, etc.). All this information are georeferenced and reported in a web-app dashboard which allows to have a clear overview of the PV plant.
