Infrared drone inspection shows PID at industrial PV plants

In order to detect possible defects or problems of solar panels, an inspection is necessary on a regular base. An alternative way of inspection is an infrared inspection by drone.

The image below shows infrared images of a drone inspection at some industrial photovoltaic installations.

An infrared inspection by drone makes it possible to detect efficiency losses caused by Potential Induced Degradation (PID). This is the case for the solar panels in the image below. The yellow color of some solar cells indicates a higher temperature, which is an important indication for PID.
