Due to the increasing energy demand and the climate crisis in the world, the importance of alternative energy generation techniques, which are clean and cheap, is increasing. Since renewable energy sources are clean and sustainable, their integration into the grids at transmission or distribution levels as distributed generation sources provides significant benefits both economically and environmentally. Rooftop solar panels are also an application of small-power renewable distributed generation technologies. In this study, the economic and environmental analysis of the rooftop photovoltaic system designed to increase the green energy usage rate and reduce the greenhouse gases released to the environment has been made. Considering the electricity consumption data and roof area of an office building of a factory located in the north of Turkey, solar radiation data obtained from three different sources such as the General Directorate of Meteorology, National Aeronautics and Space Administration, and Photovoltaic Geographical Information System were used during the analyses carried out in the Hybrid Optimization Models for Energy Resources program. By providing an annual average of 160 000 kWh (11%) clean energy generation, the annual release of pollutants such as 101.353 kg of carbon dioxide, 0.439 kg of sulfur dioxide, and 0.215 kg of nitrogen oxide to the environment has been prevented.
