With the increasingly growing number of solar energy sites, the need for better and faster fault detection techniques becomes more pressing. Using IR imaging is reliable and effective but scanning thousands or even hundreds of thousands of PV modules in mega sites quickly turns to be a time consuming and tedious task. To save on the spent effort and time digital image processing techniques can be introduced into the inspection process to help identify and annotate defects in the thermal footage

... of PV modules in an automated manner. The methodology used in the paper relies on analyzing the histogram to choose a suitable thresholding point that would help isolate the potential faulty areas in a grayscale IR image.
