It is now established practice, before embarking on the construction of the PV facility, to carry out a sample check on the modules in order to certify their good condition and to confirm the warranties given by their manufacturers.

Quality control of PV modules is an important process that should be carried out prior to the construction of an installation. Failures and manufacturing defects significantly burden the output of the facility and therefore the investment.

In recent years, the occurrence of severe weather events in Europe is becoming more and more frequent, with the most prevalent being floods and hail. PV installations could not remain unaffected by these natural disasters.

Quality control of PV modules constitutes now a necessary process taking place before the construction of an installation in order to ensure its maximum performance and to identify any failures and manufacturing defects.

It is known that the problems and failures that monocrystalline and polycrystalline PV modules often exhibit are due to various factors, both on the manufacturing side and operation/use side.

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.

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.
