Thermal imaging photovoltaic panels

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 images of solar PV panels be acquired using FLIR thermal camera?

The thermal images of solar PV panels can be acquired using FLIR thermal camera from PV panels. In this study, a previously published dataset was utilized to validate the proposed technique (Niazi et al., 2019a). The installed PV system has a rating of 42.24-kWp and located in Lahore, Pakistan.

Why is thermal imaging important for PV systems?

The short circuit and shunted cell/modules generated the heat due to the Joule heating effect. The thermal imaging can easily detect brighter spots due to temperature gradients in PV panels. The early detection of hotspots is essential to ensure the reliability and durability of the PV systems.

What is drone thermal imaging for PV inspections?

Curve Tracers)HOW DRONE THERMAL IMAGING HELPS PV INSPECTIONSTo complement and enhance manual electrical testing, the use of drone thermal imaging for PV inspections, also known as aerial thermography, is increasingly required in contracts for PV system commissioning and maintenance due to the spe

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 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. ... ...
