Electrical behavior dataset of photovoltaic mini panels under indoor and outdoor conditions

This dataset presents the electrical performance characteristics of 20 photovoltaic mini panels (ZW 86 × 82 Hi-tronic) tested under three conditions. <b><i>Test 1</i></b> : I-V curve acquisition in direct operation mode, <b><i>Test 2</i></b> : I-V dark curve measurement, and <b><i>Test 3</i></b> : I-V curve acquisition in both direct and reverse operation modes under partial shading conditions. Tests 1 and 3 were conducted in outdoor environmental conditions, capturing current, voltage, irradiance, and temperature. Key electrical parameters, including short-circuit current, open-circuit voltage, and output power, were calculated. Test 2 was performed indoors, where the current, voltage, and temperature were acquired. This dataset offers valuable insights into the real-world performance of photovoltaic systems and serves as a reference for researchers focused on modelling and parameter estimation of photovoltaic cells and arrays.
