A typical PV fault detection and classification monitoring system has two main parts—the PV system with sensors and the monitoring system for fault detection and classification. The significant components of the PVS are the PV array with irradiance and temperature sensors, the DC/DC converter with MPPT, and the DC/AC inverter.
The faults in the PV panel, PV string and MPPT controller can be effectively identified using this method. The detection of fault is done by comparing the ideal and measured parameters. Any difference in measured and ideal values indicate the presence of a fault.
The UV Fluorescence image-based technique introduced in Gabor and Knodle (2021) detects cracked cells, hotspots, erosion defects and junction box faults on domestic solar panels. A novel method for enabling detection in outdoor areas is proposed in Schuss et al. (2021), which leverages obtained thermal images to locate the region of interest .
The first aspect is the detection of PV panel overlays, which are mainly caused by dust, snow, or shading. We classify the existing PV panel overlay detection methods into two categories, including image processing and deep learning methods, and analyze their advantages, disadvantages, and influencing factors.
