Design, simulation and economic evaluation of 90 kW grid connected Photovoltaic system

Abstract

This paper presents the design, simulation and economic evaluation of a 90 kW grid-connected Photovoltaic (PV) system with nine each subsystem each comprising of 10 kW. This is installed at the rooftop of Electrical Science (ES) building of National Institute of Technology (NIT) Rourkela, Odisha, India. The simulation is performed using PVsyst 6.70 software to design the whole system properly i.e. to select the proper rating of PV panels, Inverter, tilting angle of PV panels, solar azimuth selection, shading calculation, loss calculation, performance, and technical evaluation. To monitor the power generation from the above PV system, a cloud-based data acquisition system has been used. Each of nine numbers of 10 kW grid-connected Photovoltaic (GCPV) systems is designed, simulated and installed at the rooftop of ES building of NIT Rourkela.
