PVSyst enabled real time evaluation of grid connected solar photovoltaic system

This research paper delves into the simulation of the power generation analysis of a 5 MWp solar photovoltaic (PV) plant using the design and simulation tool named PVsyst. It then proceeds to contrast the performance projected by the simulation with the real generation of an installed PV plant of the same capacity. The analysis encompasses a comparison between the genuine and simulated outcomes, underscoring the dependability and appropriateness of PVsyst. Moreover, the study evaluates key performance indicators according to the standard IEC 61724. The outcomes of the study reveal a strong connection between the projected and real system yields, which underscores the reliability of PVsyst in emulating PV system performance. Furthermore, the found that real system’s PV module, inverter and system efficiency was 11.27%, 97.49% and 11.27% respectively. PVsyst estimates a higher system efficiency as 11.39% than real system. While the actual system exhibited a performance ratio of 81.02% and a capacity utilization factor of 16.05%, the simulated system showed corresponding values of 80.42% for the performance ratio and 16.54% for the capacity utilization factor. These results underscore the potential of PVsyst as a dependable instrument for evaluating and refining rooftop solar PV systems, offering valuable insights for informed decision-making in the realm of solar energy. © The Author(s), under exclusive licence to Bharati Vidyapeeth's Institute of Computer Applications and Management 2024.
