This dataset presents the performance characteristics of photovoltaic (PV) panels under various fault conditions, including discoloration, cracks, and partial shading. The panels, SP090P Solar Plus Energy and HYBRYTEC-M5-30/12, were subjected to testing under three distinct scenarios: dirty surfaces, clean surfaces, and partial shading. Electrical parameters such as short-circuit current, open-circuit voltage, and output power, were measured, along with thermographic images to assess thermal performance under the specified conditions. Data was acquired using an electronic load system, oscilloscope, and thermographic camera, with testing conducted in outdoor environmental conditions. The results highlight the significant impact of faults and shading on the performance of PV panels, with notable reductions in power production. This dataset provides valuable insights into the real-world performance of PV systems and can serve as a reference for researchers focused on fault detection, optimization of maintenance strategies, and enhancing the overall efficiency of solar energy systems.
