Optimal Design and Simulation of a Rooftop Photovolataic System in Faculty of Engineering Guilan University

In this paper, simulation and study the rooftop photovoltaic system on building roofs of the faculty of engineering Guilan university, Iran. It is now clear that conventional plants heavily contribute to greenhouse gas emissions, so they are not environmentally friendly. Renewable energy sources are an alternative solution. In this study, the design of a grid-connected photovoltaic system was simulated. PV panels and the number of inverters are the main elements of the PV power system. According to the regional weather data and university ceiling structure, shadow analysis, calculation concerning the total number of panels, number of strings, and number of panels per string, and their optimal angles are done. PVSYST software is used for the proposed photovoltaic system design
