Performance Analysis of 20kW Rooftop Photovoltaic System Installed at MTU University Using PVsyst Software

In recent years, solar energy has come to be recognized as one of the most significant renewable energy sources. This is primarily attributable to the fact that it is an energy source that is both safe and clean and that it can be utilized indefinitely. Also, the technology behind solar panels and other devices that work with them has been improving over time. The purpose of this study is to simulate and analyze the performance of a 20 kW grid-connected photovoltaic (PV) system using the PVsyst program. The simulation was based on meteorological data, including solar irradiance, ambient temperature, and wind speed. The system has been implemented at Baghdad's MTU University. The PVsyst software was used to calculate the amount of energy that was injected into the grid, the performance ratio (PR), the reference yield (Yr), the array yield (Ya), the final yield (Yf), and other system losses. According to the results, the total amount of energy that was injected into the grid was 517MWh/year. This was accomplished by installing 96 monocrystalline PV panels with (355Wp) on the roof. The annual performance ratio was 76.5%. On the basis of these performance results, there will be motivation for an increase in the utilization of photovoltaic technology in Baghdad. Furthermore, the results of this project could motivate other universities to build a PV system in order to reduce the load and minimize the cost of delivering power to their facilities.
