ML-based techniques for surface defect detection of solar cells were reviewed by Rana and Arora , of which were only imaging-based techniques. Similarly, Al-Mashhadani et al., have reviewed DL-based studies that adopted only imaging-based techniques.
Our mobile measurement and testing equipment for on-site testing of solar modules includes A+A+A+ LED sun simulators, high-resolution electroluminescence testers and various other tests. Integrated in a small van or a container, the systems are flexible to use and easy to move from one location to another.
Nevertheless, review papers proposed in the literature need to provide a comprehensive review or investigation of all the existing data analysis methods for PV system defect detection, including imaging-based and electrical testing techniques with greater granularity of each category's different types of techniques.
Although several review papers have investigated recent solar cell defect detection techniques, they do not provide a comprehensive investigation including IBTs and ETTs with a greater granularity of the different types of each for PV defect detection systems.
Main challenges of defect detection in PV systems. Although data availability improves the performance of defect diagnosis systems, big data or large training datasets can degrade computational efficiency, and therefore, the effectiveness of these systems. This limits the deployment of DL-based techniques in practical applications with big data.
An automated EL image pre-processing pipeline for solar cell defect detection . To identify the module region, the background in the image is removed. A histogram is first used by mapping the spectral colour of the pixel intensity values to the binned colour ranges. This yields a background of colour purple (Fig. 7 (b)).
