Rooftop solar power plant design, economic and environmental analysis (Hatay province example)

Our study, conducted to examine the economic and environmental impacts of rooftop solar power plant design, aims to evaluate the contribution of solar power plants to the local economy and environmental sustainability. By considering the climatic conditions and energy demands of Hatay province, the study seeks to assess the economic and environmental effects of rooftop solar power plant design. Using the PVsyst program version 7.4, simulations were carried out, focusing on economic factors such as investment cost, electricity generation, and payback period. In the environmental analysis, the impact of converting solar energy into electrical energy on carbon emissions was examined. The designed system was assumed to have a lifespan of 25 years, and the simulation results revealed an annual energy production of 352,043 kWh, a performance ratio of %81,20, and a payback period of 4.2 years. The system demonstrated high environmental and economic efficiency, preventing 3,543.4 tons of CO2 emissions over its lifetime and enabling the transfer of excess energy to the grid, highlighting the project's environmental and economic contributions. Furthermore, the results of this study serve as an important guide for the design and implementation of solar energy projects in regions undergoing reconstruction after the 2023 Kahramanmaraş earthquakes. By examining the reconstruction process using renewable energy sources in the case of Hatay, this study can lead the way for similar analyses and the implementation of comparable systems in other regions, promoting sustainable reconstruction.
