The elevation in temperature leads to an increase in the temperature of the PV system, resulting in an augmentation of the short-circuit current within the solar cell and a concurrent reduction in the voltage level. Solar photovoltaic (PV) systems generate electricity when sunlight hits solar cells.
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)).
Another significant aspect of this study is that the Efficientb0 model has been trained from scratch using infrared solar module images. The purpose of this approach is to optimize the model’s ability to detect faults in photovoltaic panels.
This study explores the potential of using infrared solar module images for the detection of photovoltaic panel defects through deep learning, which represents a crucial step toward enhancing the efficiency and sustainability of solar energy systems.
Defects can disseminate power by creating new recombination pathways (losses), allowing the light to generate heat rather than electricity, or even consuming power stored in the battery bank, degrading the PV module's efficiency , .
These results indicate average values of 93.93% accuracy, 89.82% F1-score, 91.50% precision, and 88.28% sensitivity, respectively. The proposed method in this study accurately classifies photovoltaic panel defects based on images of infrared solar modules. 1. Introduction
