The aim of the paper is to propose a procedure
to process InfraRed (IR) images of PV modules. In fact, when
an IR image is acquired by thermo-camera, three possibilities
can happen. The first one regards the acquisition of an IR image
of a well-working PV module; in this case the IR image reveal
no anomaly. The second case regards the acquisition of an IR
image of a bad-working PV module; then, the IR image reveal
clearly the anomaly. The third one regards the acquisition of an
IR image, which gives no clear information about the health of
the PV module. In this last case, the uncertainty can be totally
or partially removed only after filtering and processing the IR
image. Proposed procedure and tools have been applied on IR
images of real PV modules.
