Photovoltaic System Thermal Images

This article presents a dataset for thermal characterization of photovoltaic systems to identify snail trails and hot spot failures. This dataset has 277 thermographic aerial images that were acquired by a Zenmuse XT IR camera (7-13 μm wavelength) from a DJI Matrice 100 drone (quadcopter). Additionally, our dataset includes the next environmental measurements: temperature, wind speed, and irradiance. The experimental set up consisted in a photovoltaic array of 4 serial monocrystalline Si panels (string) and an electronic equipment emulating a real load. The conditions for images acquisition were stablished in a flight protocol in which we defined altitude, attitude, and weather conditions.本文提出了一套用于光伏系统热特性表征、以识别蜗牛迹（snail trails）与热斑故障（hot spot failures）的数据集。该数据集包含277幅热成像航拍图像，由搭载于DJI经纬Matrice 100四旋翼无人机的禅思Zenmuse XT红外相机（工作波长7-13 μm）采集获得。此外，本数据集还包含环境温度、风速与辐照度（irradiance）三类环境测量数据。实验装置由4块串联单晶硅光伏组件构成的光伏组串（string），以及一台模拟真实负载的电子设备组成。图像采集的相关参数已通过飞行规程确定，其中涵盖飞行高度、飞行姿态与气象条件。
