Design and Simulation Application of 1 MWp Capacity Rooftop Distributed Solar Power Plant

Abstract

Photovoltaic (PV) power plants, which are one of the most important renewable energy sources, provide great opportunities in terms of clean energy, due to their almost zero harmful environmental impact and relatively easy installation, considering the solar potential of our country. In addition, the government supports offered within the scope of the Renewable Energy Resources Support Mechanism (YEKDEM) offers great opportunities to bring renewable energy resources into the economy. According to the projection made in the annual program of the Presidency of our country, an increase of 1000 MW is expected in the amount of electricity produced from solar power plants in 2022. In addition, the share of electricity produced by solar energy in the total production is expected to be 8.5%. In this study; the design and simulation application of a rooftop, grid-connected distributed solar power plant with a capacity of 1MWp was presented through the PVsyst program. In the study, it was seen that the panel slope, the right PV module, and inverter selection are extremely important. The annual amount of energy that can be supplied to the grid has been obtained as 1246 MWh. In the simulation studies, it was emphasized that such a facility, which was established compared to a power plant with equivalent energy production, would contribute positively to the impact of climate change by not emitting 14000 tons of Co2. It has been observed that revenue of 4,485,600 ₺ can be obtained from such a newly established facility for the first ten-year period with a fixed fee purchase guarantee with the domestic contribution. Considering that the life of the power plant will be 25 years, it can be said that the facility investment will be extremely advantageous even without YEKDEM support.
