6 FAQs about [Thermal imaging of photovoltaic panel cracks]

Does a thermal image indicate a fault in a PV panel?

Considering that the change of the visual image does not necessarily mean the presence of a fault in a PV panel, the thermal image of the PV panel is more favoured in the practice of PV panel condition monitoring (Kandeal et al., 2021a).

Can thermal imaging be used to identify a solar PV module?

One of the significant challenges is the fault identification of the solar PV module, since a vast power plant condition monitoring of individual panels is cumbersome. This paper attempts to identify the panel using a thermal imaging system and processes the thermal images using the image processing technique.

Can thermal imaging detect and localize solar panel damage?

This research suggests a way for detecting and localizing solar panel damage using thermal imaging, which could get rid of the requirement for manual visual examination. The suggested technology detects and localizes hotspots on the surface of solar panels, which indicate faults or damage.

Can thermal imaging be used to identify PV panel failure points?

In , the authors have verified that high accuracy fault identification is possible by performing thermal imaging analysis of PV panels and using radiation sensors. V. Kirubakaran et al. use a thermal imaging system combined with image processing to record PV panel failure points.

How to detect small cracks in PV modules?

Detecting small cracks in PV modules is a challenging task. These cracks can occur during production, installation and operation stages. Electroluminescence (EL) imaging test procedure is often used to detect these cracks. Defective images with linear and star cracks obtained from EL are collected.

Can El imaging detect cracks in solar cells?

According to Fig. 9, a solar cell sample has been observed using EL imaging technique. As noticed, multiple cracks appear in the EL image, where in fact, the detection of the cracks have been improved using the proposed algorithm.
