6 FAQs about [Infrared photovoltaic panel detection and analysis]

How to detect hot spot defects in infrared image PV panels?

Aiming at the problem of difficult operation and maintenance of PV power plants in complex backgrounds and combined with image processing technology, a method for detecting hot spot defects in infrared image PV panels that combines segmentation and detection, Deeplab-YOLO, is proposed.

Can drone IR cameras detect faults in solar PV plants?

The objective of this research is to compare the fault detection analyses performed, for two different solar PV plants, using alternatively an unmanned drone and a manned aircraft as aerial platforms, equipped with different IR cameras to provide reliable and comparable thermal images over the same inspected sites.

How to detect PV module anomalies in IR images?

Detection of PV module anomalies Similar to the PV module detection, many existing works identify anomalous PV modules in IR images with classic image processing techniques. The most popular one is binary thresholding of image intensities, which segments hot regions of PV modules corresponding to thermal anomalies [ 91, 92, 97, 102, 104, 109 ].

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 infrared thermography detect PV plants?

An overview for infrared thermography (IRTG) detection of PVs is introduced. Classification of IRTG techniques, detected faults are discussed in detail. The manuscript provides a good guide for selecting a proper IRTG system for PV plants.

Can a deeplab-Yolo hot-spot defect detection method be used to detect PV panels?

This article proposes a Deeplab-YOLO hot-spot defect detection method that combines segmentation and detection with infrared images and based on the differences and features in the shape, size, and color of PV panels and hot spots. On the one hand, it can meet the accuracy of segmentation and enhance the edge features of the target.
