Feasibility, simulation and selection of rooftop solar power plant alternatives

The energy needs with the development of science and technology in the world and Turkey is increasing day by day. To meet country requirements; it has become inevitable to seek alternative sources in energy production, to follow technical and economic developments closely, to sustain and carry out developments in the field of energy. Today, renewable energy sources have become very important and studies in this area are gaining momentum. Among the renewable energy sources, the share of solar energy in electricity production has an important place. In this study, a solar power plant was installed on an industrial roof operating in the organized industrial zone. The system components to be used have been determined. With the PV*SOL simulation program, simulations were made for 4 different options consisting of different brands of panels and inverters. With the data obtained as a result of the simulation, the feasibility study of a factory with consumption and how many years the system would pay itself were calculated. AHP-VIKOR integrated approach was used to evaluate the feasibility and simulation results. First of all, the criteria weights were determined by the AHP method, and then a concession solution was reached by sorting with the VIKOR method. As a result of the comparisons made between 4 different options consisting of different brands of panels and inverters, the optimal option was decided.
