Two typical visible defects of PV modules, snail trails and dust shading, are characterised and the defect detection through image processing algorithms based on first order derivative of Gaussian function and feature matching is carried out for the aerial PV module images captured by visible light cameras.
In recent years, aerial defect inspection methods have emerged as cost-efficient and rapid approaches, proving to be reliable techniques for detecting failures in photovoltaic (PV) systems.
EL imaging is a potent method for identifying defects in solar PV modules, but its limitations in daytime can make it intractable to use in certain situations contexts. Under these conditions, thermal imaging or other non-destructive evaluation techniques might be more suitable for inspecting solar PV systems during the day.
Defects and faults in solar PV systems can be detected and diagnosed by analyzing sensor data, such as visual, thermal, and electroluminescent images, and identifying anomalies through various AI techniques, thus enhancing system reliability and maintaining optimal performance .
Neural Networks Neural networks, particularly deep-learning models, have emerged as the most popular and effective AI method for detecting defects in solar PV modules, both through thermal imaging and I-V curve analysis.
Discoloration is a common defect for PV modules, especially for a plant located in the desert. The statistics in Ref. indicated that encapsulant discoloration occurred for all 608 modules located in Algeria. The defects, yellowing and browning can cause the primary power loss in the whole PV system [, , ].
