Performance of Photovoltaic Panels with Different Ages Under Outdoor Conditions

This dataset, includes measurements of voltage, current, characteristic parameters, temperature, and irradiance of two photovoltaic panels refrences. Seven polycrystalline photovoltaic panels (10 W) with over 10 years of use from the brand ERDM, model Hybrytec 10/12, and a new Restarsolar photovoltaic panel, model RT010P (10 W) were measured.
The information is organized into two folders: "RawData" and "ProcessedData". The files within the RawData folders contain the voltage [V] and current [A] panel vectors (V and I) delivered by the oscilloscope, as well as the temperature data [°C] and irradiation [W/m2] measured at the time of the test (T and G); on the other hand, the files within the ProcessedData folder include the voltage [V] and current [A] data of the panel necessary to reproduce the I-V and P-V curves (V and I) and some data of interest extracted from the curves I-V, P-V, such as the open circuit voltage (Voc) [V], short circuit current (Isc) [A], maximum power point current (Impp) [A], maximum power point voltage (Vmpp) [V] and power in that point (Pmpp) [W].
This dataset could be used in studies to compare the performance of different parameter estimation methods of circuit models of photovoltaic panels, they could help to develop predictive models for energy generation and enhance the accuracy of photovoltaic simulations and additional experimentation and comparative analysis could be conducted to examine the PV power degradation rate based on the electrical parameters of the tested datasets.
The names of the files in the “RawData” folders follow the format: RefCurve_yyyy-mm-dd_s_hhmmss.Wfm.csv; and the "ProcessedData" files corresponds to each panel reference and panel number: ERDM_Px.mat (where x refers to panel number).

本数据集包含两块参考光伏板的电压、电流、特性参数、温度及辐照度测量数据。本次测试共纳入7块品牌为ERDM、型号为Hybrytec 10/12的多晶硅光伏面板（polycrystalline photovoltaic panels），单块功率为10 W，已服役超过10年；另有1块全新Restarsolar品牌、型号为RT010P（10 W）的光伏面板参与测量。

数据集按两类文件夹进行组织：「原始数据（RawData）」与「处理后数据（ProcessedData）」。RawData文件夹内的文件包含示波器采集的光伏板电压[V]、电流[A]矢量数据（即V与I），以及测试时刻记录的温度数据[°C]与辐照度[W/m²]（即T与G）；而ProcessedData文件夹内的文件则包含复现电流-电压（I-V）与功率-电压（P-V）曲线所需的光伏板电压[V]、电流[A]数据，以及从I-V、P-V曲线中提取的关键参数，例如开路电压（open circuit voltage, Voc）[V]、短路电流（short circuit current, Isc）[A]、最大功率点电流（maximum power point current, Impp）[A]、最大功率点电压（maximum power point voltage, Vmpp）[V]以及该点的输出功率（Pmpp）[W]。

本数据集可用于开展对比研究，以评估不同光伏板电路模型的参数估计方法性能；同时可助力构建光伏发电预测模型，提升光伏仿真的准确性。此外，还可基于本次测试数据集的电气参数开展额外实验与对比分析，用以探究光伏功率衰减速率。

RawData文件夹内的文件命名遵循格式：RefCurve_yyyy-mm-dd_s_hhmmss.Wfm.csv；ProcessedData文件夹内的文件则对应每一块参考光伏板与板号，命名格式为ERDM_Px.mat（其中x代表光伏板编号）。
