PV module XHYG-10W XKD-50W Cell Technology Poly-Crystalline Mono-Crystalline Maximum Power 10 W 50W Voltage at Maximum Power Point 9V 17.82V Current at Maximum Power Point 1.12A 2.8A Open-circuit voltage 10.71V 22.02V Short-circuit current 1.23A 3.18A The number of cells 20 36 The experiments used four-series connected PV modules operating under both UICs and PSCs. The PV cellswere shaded by light films to simulate different PSCs. AYHT309 thermometer with Type-K thermocouple probes was installed to measure the temperature of the PV panels. The solar irradiance was measured by a standard 2 cm2 cm mono-crystalline PV cell which has been calibrated by the National Institute of Metrology, China. A Fluke F289C multimeter measured the cell’s short circuit current. A PROVA-1011 PV system analyzer has the capability of generating the I-V data under a specific environmental condition. In the dataset, there are 24 testing cases by using multiple-level numbering. The first item indicates the number of irradiance levels receiving by the applied PV string, while the second item represents the case number. For example, “4-2" means the second test case with four different irradiance levels. All the data were collected at the Xi’an Jiaotong-Liverpool University’s south campus (east longitude 120o75’, north latitude 31o28’) in March 2021. The column headings for the tabular data are defined as follows: I terminal current (A) V terminal voltage (V) T temperature (oC)

本实验采用四串连接的光伏组件，分别在不均匀光照条件（Uneven Irradiance Conditions, UICs）与部分遮阴条件（Partial Shading Conditions, PSCs）下开展测试。通过透光薄膜遮挡光伏电池片以模拟不同程度的部分遮阴效果。搭载K型热电偶探头的AYHT309温度计用于测量光伏面板的表面温度。太阳辐照度通过经中国计量科学研究院校准的标准2 cm × 2 cm单晶硅光伏电池进行采集。使用福禄克F289C万用表（Fluke F289C）测量该标准电池的短路电流。采用PROVA-1011光伏系统分析仪采集特定环境条件下的I-V特性数据。

本数据集共包含24组测试案例，采用多级编号规则进行标识：第一位数字代表待测光伏串所接收的辐照度等级总数，第二位数字代表该辐照度等级组合下的测试案例序号。例如，“4-2”代表包含4种辐照度等级的第2组测试案例。所有数据均于2021年3月，在西交利物浦大学南校区（东经120°75′，北纬31°28′）完成采集。

表格数据的列标题定义如下：
I：端子电流（单位：安培，A）
