Abstract
This paper investigates defects in photovoltaic (PV) panels, more precisely, the location of defects in PV panels. With the help of electrical verification, it is possible to verify the impact of defects on output performances. However, it is not possible to determine the location of defects in order to address problems, for example in the manufacturing process of PV panels. In this paper, the focus lies on finding similarities in the location of defect areas in PV panels. Samples were characterised with the help of synchronized thermography (ST) in order to obtain infrared (IR) images of PV panels. IR-images are helpful to get a visual image on the health of PV panels and identify the position of defects. This information can be useful, for example to improve the fabrication process of PV panels.
