Abstract
The objective of the research is to design and evaluate the grid-connected solar photovoltaic roof-top system at Tetulia, Panchagrah, Bangladesh using PVsyst software.The main factors of this research are the move toward renewable energy like PV with environmental consequences.The overall performance of a photovoltaic cell is determined by the amount of solar irradiation, the type of PV module used, and the orientation of PV module.Now, the grid-connected PV system is the best choice for large-scale renewable energy.For the case study, PVsyst software is used to analyze a 3kW solar PV plant installed on a rooftop for residential load consumption of 8.1kWh/day.The available AC energy generated by the PV panels is 4172kWh/year, and 1871kWh/year of surplus energy is supplied to the grid after daytime power demand is met.The yearly global horizontal irradiation of Tetulia, Panchagrah is 1485.4kWh/m 2 and during the night, the quantity of electricity imported from the grid is 1050kWh/year.This technology helps in the prediction of power outages and backup energy storage because it makes use of the energy stored in the batteries.
