Based on BIM, regions with abundant solar radiation were chosen for the purpose of installing the PV system and exploiting them in energy production. A simulation of a 6.96 KWh grid-connected rooftop PV system was performed by using PVsyst and PV*SOL software. A 3D single family house that was proposed by the municipality of the Turkish city of Elazig was designed and simulated using PVsyst and PV*SOL software based on BIM. Comparison and evaluation were carried out for the annual energy yield, performance ratio, specific production and energy feed into the grid of the PV system from each software. It has been shown that very similar results are obtained from the simulations of these softwares. Keywords PV system, solar energy, BIM, PVsyst, PV*SOL, solar radiation. 1. Introduction Environmental problems and climatic disturbances caused by the use of fossil fuels such as coal, gas and oil as a major source of energy represent the trigger point for the use of clean energy sources [1]. This transformation calls for uniting all efforts to make this goal a reality and involves researchers, skilled workers, educated consumers, as well as the support required from governments and political decision-makers. For this transformation, one of the most important - and abundant - sources of renewable energy is solar energy. Solar energy is an inexhaustible source and is one of the most promising sources of energy to generate electricity and reduce emissions of harmful gases [2]. It is a well-known fact that the solar energy available at a particular location is not the same throughout the year, and it also varies from location to location. It is therefore important to know the climate data before installing solar systems. The economic feasibility of a photovoltaic systems should be analysed before the installation [3]. After the installation the solar system needs to be operated as efficiently as possible under standard operating conditions [4]. As the world turns to renewable energy sources, photovoltaic technologies are developing rapidly despite the high cost and complex technology of the photovoltaic cells
