Analysis of A Photovoltaic System Planned to be Installed Under Diyarbakir Conditions Using Pvsyst and Pvsol Software

Abstract

In this study

in case of a grid-connected photovoltaic system to be installed in Diyarbakır conditions

the plant to be installed was simulated using the trial versions of PVsyst and PVSOL programs. For the study

the roof of Technical High School in Diyarbakır province was selected as a sample study area. As a result of the simulations

the performance and economic analysis of the system were performed together. As a result of the analyses

it was observed that the data of both programs were close to each other. The performance data of the system was analyzed

the approximate cost was calculated and the time for the system to cover its own cost was calculated approximately. Thus

these programs made significant contributions to us both in terms of predicting the performance of our system and the payback period of the system. The novelty of this study lies in conducting a comparative performance and economic assessment of PVsyst and PVSOL simulation tools under the climatic conditions of Diyarbakır

which is one of the regions with the highest solar energy potential in Turkey but has been rarely investigated in the literature. Unlike previous works that mainly focus on general PV performance

this study evaluates the consistency and differences between two widely used simulation programs. The comparative analysis provides additional insights into the accuracy and reliability of software-based predictions

which can support more informed PV project planning and investment decisions in southeastern Turkey.
