Performance Assessment of a 15.08 kWp Grid-Connected Solar PV System in Bangladesh with PVsyst Simulation

This study presents the design and performance assessment of a grid-connected solar photovoltaic (PV) system installed at the National Institute of Textile Engineering and Research (NITER), Bangladesh. Using PVsyst simulations with local climatic data, the technical feasibility, economic viability, and environmental benefits of a medium-scale rooftop PV installation were evaluated. The system’s configuration, energy yield, performance ratio, and loss mechanisms were analyzed to determine operational efficiency. Economic analysis assessed potential savings, while environmental evaluation considered reductions in carbon emissions and contributions to sustainable energy goals. The results demonstrate that grid-tied PV systems can provide reliable electricity, support climate action, and offer economic advantages for academic institutions.
