6 FAQs about [Photovoltaic panel el semi-finished product inspection]

Can El images be used for photovoltaic panel defect detection?

Buerhop et al. 17 constructed a publicly available dataset using EL images for optical inspection of photovoltaic panels. Based on this dataset, researchers have developed numerous algorithms 9, 10, 12 for photovoltaic panel defect 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 power plant in-situ El testing?

In conclusion, PV power plant in-situ EL testing, particularly through innovative drone-based technologies, represents a paradigm shift in ensuring the performance and reliability of PV power plants.

Should El imaging be performed in-situ at PV power plants?

Thus, conducting EL imaging in-situ at the PV power plants is a good measure. As proposed by the EU Horizon 2020-funded SolarBankability studies and Solar Power Europe conducting IEC62446 and additional tests, like that of site EL imaging are a best practice.

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.
