Is there a fault diagnosis method for PV modules based on infrared images?

Here, a fault diagnosis method for PV modules based on infrared images and improved MobileNet-V3 is proposed.

How to use RPA and IR for inspection & fault diagnosis of PV modules?

Using RPA and IR for the inspection and fault diagnosis of PV modules follows several steps given by Figure 1 and depends on two main technologies: The first is collecting IR images through RPA, the second key technology include PV modules’ anomaly detection and defect classification based on IR images.

Can a light convolution neural network detect photovoltaic cell cracking defects?

To reduce the detection network complexity, Akram et al. 11 proposed a light convolution neural network based on a visual geometry group network for detecting photovoltaic cell cracking defects. It requires lower computational power, so it can detect defects without using a graphics processing unit.

How to improve the quality of infrared images of PV modules?

According to the characteristics of low contrast and unbalanced number of images in the dataset, the histogram equalization and Mixup method are used to enhance the quality of infrared images of PV modules, thereby improving the accuracy of PV module fault diagnosis based on infrared images and deep learning methods.

How can IR imaging be used to identify a PV module defect?

Defects on PV modules cause temperature differences and based on this, different types of defects can be identified through the inspection of temperature distribution [ 6 ]. IR imaging provides a real-time two-dimensional image of PV module from which temperature distribution of the module surface can be assessed [ 7 ].
