Abstract:

As the world increasingly focuses on sustainable energy solutions, solar photovoltaics (PV) emerge as crucial components in this transition. This research examines the comparative performance of fixed-tilt and sun-tracking PV systems through digital simulations using the PVGIS tool, with a specific focus on the geographic setting of Niš, Serbia. The study confirms that sun-tracking systems significantly enhance annual energy production, with dual-axis trackers outperforming fixed systems by approximately 30%. The analysis reveals that tracking systems not only increase the overall energy yield but also reduce seasonal output variability, particularly enhancing performance during winter months. These results underscore the importance of considering both tilt and tracking mechanisms in the design of PV systems to optimize energy sustainability. The use of digital simulation tools like PVGIS provides valuable insights into the potential enhancements achievable through strategic system configuration, supporting the effective planning and optimization of solar energy projects for enhanced sustainability.
