Comparison of production and simulation values of a solar power plant and loss analysis: Case of Beştepe energy company

Among the sources of renewable energy, solar energy is a source of energy with great potential. Various simulation programs are used in feasibility studies during the installation phase of solar power plants and it is important for the investor to match the values obtained as a result of these simulations with the electricity production values realized after the installation. This is why the pre-investment feasibility studies presented by simulation programs play an important role in determining the most suitable investment area. But also in terms of efficiency and benefit / cost analysis in building such a plant. In this sense, the coherence of the techno-economic analysis offered by the simulation programs makes a significant positive contribution to the proliferation of solar power plants which are respectful of the environment. The purpose of this study is to determine the differences between production data and financial data after the implementation of the amortization process (reimbursement rate) calculated in the feasibility phase of solar power plants. In this context, this thesis aims to test the consistency of the feasibility studies organized by the supplier companies in charge of producing the feasibility report. To this end, the archival data obtained from the Beştepe Energy company and the feasibility reports submitted by the supplier companies before the investment were examined. In this study, the simulation of a solar power plant of 1125 kWp / 1000 kW established in the province of Aksaray, in the district of Merkez in Gençosman was carried out with the help of the software PVSYST 7.1. The actual production values of the system after installation were taken into account and compared to the simulator data. The results obtained show that the PVSYST simulation program produces values very close to the actual production values. It seems that the losses are caused firstly by high temperature and secondly by the choice of properties of solar panel used.
