Open Dataset of Current–Voltage Curves for a Photovoltaic Panel Under Partial Shading Conditions with Variable Irradiance per Section

This file presents an open photovoltaic performance database consisting of 14,400 current–voltage (I–V) curves generated from the simulation of a photovoltaic panel divided into six independent sections subjected to varying irradiance levels. Each section was exposed to irradiance values ranging from 100 to 1,000 W/m² in increments of 100 W/m², resulting in a comprehensive combinatorial dataset that captures a wide range of partial shading scenarios. The database is organized into 10 simulation scenarios, each containing 1,440 I–V curves with a resolution of 2,071 data points per curve. All scenarios share a common voltage sweep vector, and each scenario file provides the corresponding output current data. An irradiance reference file records the 14,400 unique irradiance combinations across the six sections. The dataset was developed to support research on photovoltaic system modeling, maximum power point tracking (MPPT) algorithms, fault detection, and machine learning applications under non-uniform irradiance conditions. By providing a structured and reusable source of I–V characteristic data, this dataset contributes to the advancement of photovoltaic performance analysis and the development of intelligent energy management strategies. The dataset comprises 14,400 unique configurations of a photovoltaic panel divided into six sections; each assigned an irradiance level from 100 to 1,000 W/m². For every configuration, a complete I-V curve was simulated with 2,071 points, using a voltage sweep from 0 to 41.4 V in 0.02 V steps. The configurations are organized into 10 scenarios of 1,440 curves each, stored as separate files. This modular organization allows users to load and analyze individual subsets without processing the entire database at once.
