For a photovoltaic power plant, design before and after of installation technoeconomic comparative analysis

In this study, the installation of a solar power plant on the roof to meet the energy needs of a factory in Bilecik was discussed. At the beginning of the study, the power to be installed on the roof was determined and calculations were made with the pvsyst system according to the material properties to be used based on the sun exposure time, shading and the power to be installed. After the materials were determined, the cost calculation was made and the depreciation period was determined according to the production capacity. After the design of the system in question was installed on the field in the factory, production data and cost calculations were taken monthly for a year and profit wages were obtained by calculating the production values and kw/h fee. By recalculating the amortization period according to the earnings fee, it has been observed that the rooftop solar power plant is advantageous in terms of cost. As a result of the study, it is concluded that utilizing the roof areas of factories in our country will be beneficial in terms of energy.
