The detection methods before photovoltaic panel installation are

This paper presents an innovative approach to detect solar panel defects early, leveraging distinct datasets comprising aerial and electroluminescence (EL) images. The decision to employ separate datasets with different models signifies a strategic choice to harness the unique strengths of each imaging modality.

As any energy production system, photovoltaic (PV) installations have to be monitored to enhance system performances and to early detect failures for more reliability. There are several photovoltaic monitoring strategies based on the output of the plant and its nature. Monitoring can be performed locally on site or remotely.

A typical PV fault detection and classification monitoring system has two main parts—the PV system with sensors and the monitoring system for fault detection and classification. The significant components of the PVS are the PV array with irradiance and temperature sensors, the DC/DC converter with MPPT, and the DC/AC inverter.

Visual assessment should be carried out before and after module installation to evaluate effect percentage of electrical, mechanical, and environmental stress on the PV module. In converter and BOS devices, visual inspection allows one to recognize disconnections, burning parts, defect in supporting structure (see Fig. 2) as well as problems .

Lastly, the selective kernel network is added before the detection head to strengthen its ability to recognize multi-scale targets. Compared to previous models, the proposed tool demonstrates superior efficiency, accuracy, and robustness in identifying defects from visible light images of photovoltaic panels.
