The PID or Potential Induced Degradation is a phenomenon that has appeared in PV modules in the past few years. The reason for this appearance is the designing of PV installations with long strings that develop high voltage. This voltage in many cases nears 1000 V and serves the reduced energy losses in the pipelines.

Conditions for proper thermography of PV modules
Manufacturers of thermal imaging cameras, e.g. FLIR, note that PV module thermography can be performed when the incident radiation on the surface of the Pv modules is at least 500 Watt/m2, and preferably above 700 Watt/m2.
