Today, with the developing technology and increasing population, the demand for energy is increasing rapidly and it is a scientific fact that the existing resources can meet this demand for a very short time. In addition, increasing carbon emissions due to increasing population density and energy demand cause air pollution and climate change. In order to avoid such environmental impacts and to meet the ever-increasing energy demand worldwide, the use of renewable energy sources, which is an environmentally friendly and clean energy source, has become almost a necessity. For this reason, on-site and rooftop solar power plant installations are increasing rapidly worldwide.
There are two very important criteria in rooftop solar power plant installations. These are roof statics (load bearing capacity) and roof insulation. Without these two criteria, the solar energy system on the roof should not be installed. Extra loads on the roof originating from the solar power plant to be installed should be analyzed with static calculations to be made and installation should be made according to the results of these calculations. Also, before installing on the roof, it should be checked whether there is an insulation problem on the roofs. If there is an isolation problem, this should be resolved before the installation of the exchange.
The design of the east-west oriented solar power plant established in Hidayet Türkoğlu Sports Complex is explained. The main simulation programs used while designing the solar power plant are mentioned. It was revealed by simulation results that an east-west oriented solar power plant was established and that more solar energy could be utilized in the unit area compared to a southern oriented power plant in the current area. In addition, the production values of the south-oriented and east-west oriented power plants with the same powers have been simulated and compared. However, real-time production values obtained from the data recording and monitoring system of the existing 169 kWp east-west oriented solar power plant established in 2016 were compared with the simulation results.
The total cost of the solar power plant with an east-west oriented optimizer on the roof with an installed capacity of 169 kWp installed in Hidayet Türkoğlu Sports Complex in 2016 is 850.00 TL + VAT and the unit price of electricity is 0.43 TL / kWh. According to the cost analysis based on the said prices, the investment return period of the 169 kWp solar power plant was calculated as 15.7 years. The cost of solar panels, which constitute more than half of the investment of the system with the developing technology since the establishment of the plant, has decreased by up to 30% worldwide. However, this decrease in solar panel prices has not been felt significantly due to the increasing exchange rates in our country in the recent period. The system in question can now be established with the current price of 750,000 TL + VAT. According to the cost analysis based on the current cost and the current electricity unit price of 0.82 TL / kWh, the investment return period of the said solar power plant was calculated as 6.7 years. However, the current cost of the southern oriented solar energy system with the same system features and an installed power of 110.5 kWp that can be installed in the same area is 515,000 TL + VAT compared to 2020. According to the cost analysis made based on the current system cost and the electricity unit price, the investment return period of the said solar power plant was calculated as 6.5 years. Compared to 2020, the cost of an east-west oriented solar power system with an installed power of 169 kWp is 750.000 TL + VAT, while the cost of a southern oriented solar power system with an installed power of 110.5 kWp is 515.000 TL + VAT. In the initial investment phase, the east-west oriented solar energy system with 169 kWp installed power is 235.000 TL + VAT more cost compared to the south-oriented solar energy system with 110.5 kWp installed power. Investment return periods of east-west oriented systems are shorter in regions close to equator.
