Enhanced Optimum Design and Performance Evaluation for Grid-Connected Solar PV Rooftop Systems: A Case Study for Bangladesh

Load-shedding has been rising because of a vast gas shortage that has led to Bangladesh's significant fall in power generation. Renewable energy sources could help Bangladesh's electricity production overcome these problems. The roof-mounted solar PV system is a desirable alternative energy source. Location, design, appropriate installation, and solar module type all affect the performance and efficiency of a PV system. The PV simulation tool computes how much electricity will be produced by the PV array setup. The energy efficiency of rooftop PV systems is significantly impacted by the design and orientation of roofs. By increasing the energy production of rooftop PV systems through improved roof design, this study seeks to close a knowledge gap. In this study, we used SketchUp and PVsyst to design and simulate a grid-tied rooftop solar photovoltaic system for Bangladeshi educational-type consumer loads. This project also attempts to lower grid outages close to the building, energy costs (COE), grid dependence, and CO2 emissions. The suggested system has been accurately modeled, considering factors such as choosing the most suitable PV panel rating, inverter, tilt angle, sun azimuth, shading calculation, loss calculation, performance, and technical assessment. The electric grid receives extra energy. The suggested system will generate electricity efficiently, minimizing reliance on the grid, as shown by the real-time simulation.
