Abstract

In recent years, aerial defect inspection methods have emerged as cost-efficient and rapid approaches, proving to be reliable techniques for detecting failures in photovoltaic (PV) systems. These methods are designed to swiftly conduct comprehensive monitoring of PV power plants, spanning from the commissioning phase to the entire operational lifetime. This paper presents a literature review on reported the aerial EL framework for PV system inspection. EL inspection on PV modules can be used to detect of defects, cracks, shunting, etc., with the aim of assisting to overcome any possible future major breakdown in the modules. While there are comprehensive review articles covering subjects such as infrared thermography (IRT), digital image processing (DIP), EL inspection classification, and deep learning techniques, there is currently no focused review exclusively on aerial EL inspection. In this mini review, we delve into the latest articles on aerial EL inspection, highlighting both the advantages and drawbacks of this technique. The contribution of this paper is to provide a focused review of the aerial EL inspection technique as a cutting-edge solution for evaluating module quality and identifying defective modules or problem areas.

利用航空电致发光 (EL) 对光伏太阳能模块进行缺陷检测：综述

近年来，空中缺陷检测方法已成为一种经济、快速的方法，被证明是检测光伏（PV）系统故障的可靠技术。这些方法旨在迅速对光伏电站进行全面监测，从调试阶段到整个运行寿命。本文对光伏系统检测的航空 EL 框架进行了文献综述。光伏模块的 EL 检测可用于检测缺陷、裂缝、分流等，目的是帮助克服模块未来可能出现的任何重大故障。虽然有一些综述文章涵盖了红外热成像 (IRT)、数字图像处理 (DIP)、EL 检测分类和深度学习技术等主题，但目前还没有专门针对航空 EL 检测的重点综述。在这篇小型综述中，我们将深入探讨有关航空 EL 检测的最新文章，重点介绍这种技术的优点和缺点。本文的贡献在于对航空电致发光检测技术进行了重点综述，将其作为评估模块质量和识别缺陷模块或问题区域的前沿解决方案。
