Infrared detection of photovoltaic panels

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 remote sensing detect anomalies in photovoltaic systems?

In this research, a remote sensing method is proposed for the fast and efficient detection of anomalies in photovoltaic (PV) systems. An infrared radiation (IR) camera mounted on flying vehicles (e.g., drone) to capture IR images of solar panels. Then, convolutional neural networks (CNN) are developed to detect abnormal cells in the PV systems.

How do IR cameras detect abnormal cells in solar panels?

An infrared radiation (IR) camera mounted on flying vehicles (e.g., drone) to capture IR images of solar panels. Then, convolutional neural networks (CNN) are developed to detect abnormal cells in the PV systems. The CNN model are then quantized and implemented on edge devices for real-time detection of anomalies.

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.

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.
