4 FAQs about Brand new defective photovoltaic panels

What are the different types of defects in PV panels?

As illustrated in Fig. 1, the common types of defects in PV panels include crack, finger interruption, black core, thick line, star crack, corner, horizontal dislocation, vertical dislocation, and short circuit often accompanied by complex background interference. However, defect detection in EL images requires highly specialized knowledge.

What are the different types of solar panel problems?

Microcracks are another type of solar panel problem. They typically occur during solar cell manufacturing and module assembling. Unfortunately for the owners of solar panels, microcracks are hard to detect with the naked eye.

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 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.
