6 FAQs about [Solar cell array damage detection]

What are the challenges of defect detection in PV systems?

Main challenges of defect detection in PV systems. Although data availability improves the performance of defect diagnosis systems, big data or large training datasets can degrade computational efficiency, and therefore, the effectiveness of these systems. This limits the deployment of DL-based techniques in practical applications with big data.

Can infrared solar module images detect photovoltaic panel defects?

Why should we study solar panel defects?

This study can provide a significant contribution to the maintenance and efficiency of solar energy systems. Due to solar panel defects occurring on the panel, the absorption of solar radiation on the solar cell side will be low or absent. Therefore, defects must be detected easily and accurately.

Should a PV array be isolated if a fault is detected?

In the absence of localization, the common practice has been to isolate the entire PV array upon the detection of a fault, which does not augur well for the reliability of power supply. Next, localization saves time and labour which otherwise would have gone into fault tracing by the maintenance team. 7.2.4. Criterion 4: Fault Isolation
