Photovoltaic panel deflection detection

What is PV panel defect detection?

The task of PV panel defect detection is to identify the category and location of defects in EL images.

What is PV panel overlay detection & fault detection?

PV panel overlay detection and PV panel fault detection are both directly related to the performance and efficiency of solar power generation systems. PV panel overlay detection aims to detect whether there are shelters or pollutants on the surface of PV panels.

How to detect photovoltaic panel faults?

Common analysis methods include equivalent circuit models, maximum power point tracking algorithms, etc. The principle of using the hybrid method to detect photovoltaic panel faults is to combine the advantages of intelligent method and analytical method, aiming to improve the accuracy and robustness of photovoltaic panel fault detection.

Why is fault detection important for PV panels?

Fault detection can help detect PV panel damage and problems such as hot spots, cracks, partial shading, and electrical failures. These issues can lead to a decrease in panel output power and imbalances in current and voltage, lowering overall system power generation efficiency [ 34 ].

Can a real-time defect detection model detect photovoltaic panels?

Efforts have been made to develop models capable of real-time defect detection, with some achieving impressive accuracy and processing speeds. However, existing approaches often struggle with feature redundancy and inefficient representations of defects in photovoltaic panels.

What is PVL-AD dataset for photovoltaic panel defect detection?

To meet the data requirements, Su et al. 18 proposed PVEL-AD dataset for photovoltaic panel defect detection and conducted several subsequent studies 19, 20, 21 based on this dataset. In recent years, the PVEL-AD dataset has become a benchmark for photovoltaic (PV) cell defect detection research using electroluminescence (EL) images.
