Electrical Data Collection of a Set of Mini Panels in Indoor and Outdoor Environments
Description
This dataset collects electrical information in photovoltaic mini panels, focusing on three main conditions: I-V curve acquisition in direct operation mode, I-V dark curve measurement, and I-V curve acquisition in both direct and reverse operation modes under partial shading conditions (Test 1, Test 2 and Test 3, respectively). The mini panels, ZW 86X82 Hi-tronic, were subjected to testing under different environmental conditions (indoor and outdoor). Variables measurements such as voltage, current, temperature, and radiation were included for each test. The time series of electrical data for each panel and each condition are saved using Matlab .mat format. This dataset can be a reference for researchers focused on modeling and parameter estimation of photovoltaic cells and panels.

Steps to reproduce
Experiments on photovoltaic mini panels were conducted at the Laboratory of Power and Electrical Energy of the Instituto Tecnológico Metropolitano in Medellín, Colombia. Parameters measured in this study: solar irradiation, I-V curve, and temperature. Test 1: named direct mode tests, was acquired on Jun 22, 2022, from 8:00 am to 1:00 pm in outdoor conditions. The data was taken at three different irradiation levels for each mini panel (Irr1, Irr2, and Irr3). Test 2: mini panels dark tests were taken on Aug 28, 2023, from 11:00 to 01:00 pm in indoor conditions without irradiation in the front mini panel surface. Test 3: Direct and reverse mode tests, with a 20 series mini panel array. The first step is to select a mini panel. Then, capture current and voltage information in the array and the selected mini panel terminals under three conditions: without shading in the selected area. Testing Instruments: Twenty mini solar panels with reference ZW 86X82 (Hi-tronic). Measuring Instruments: An oscilloscope Tektronix MDO 3024 was used to acquire the electrical variables (voltage and mini panel current); the irradiation and the temperature were acquired with a Fluke FLK-IRR1-SOL solar irradiance meter. The voltage sweep was made by programming a BK precision 8514 electronic load. Software: The data processing was developed in Matlab.
