Modeling and Performance Analysis of a Rooftop Photovoltaic System for Batman: Impact of Seasonal Shading on Energy Efficiency

Abstract

Today, the limited availability of conventional energy resources and increasing environmental impacts necessitate the use of renewable energy sources. In this context, solar energy stands out as a sustainable alternative and photovoltaic (PV) systems provide efficient conversion of this energy. In this paper, the modeling and simulation of a rooftop PV system for Batman Dicle Elektrik Dağıtım A.Ş. (DEDAŞ) building is investigated. The aim is to reduce energy costs and increase environmental sustainability by utilizing solar energy. PVsyst software was used to design the PV system and its performance was simulated under various shading scenarios. The results show that shading leads to significant losses in energy production, especially in winter, with losses of up to 28% observed in December. In summer, the effect of shading is reduced and only 4% loss was recorded in June. The study reveals that PV systems that take into account local climatic and geographical conditions offer significant opportunities to expand the use of renewable energy and constitute a valuable resource in the design and optimization processes for similar projects
