Özet:

In this study, techno-economic and environmental feasibility analyzes of meeting the electrical energy required for irrigation need of agricultural land of 10,000 m2, which is considered to be independent of the grid, in the rural area of Polatlı district of Ankara, with a solar-wind hybrid renewable energy system, were carried out using HOMER-Pro software. The electrical load required for irrigation was determined as 64 kWh/day. In addition, it is assumed that the electrical load of a house with an electrical load of 11.25 kWh/day close to the agricultural land will be met by the hybrid energy system to be installed. As a result of the examinations, it has been determined that the use of the hybrid energy system with solar-wind power to be created with a solar panel of 22.1 kW, a maximum power point tracking (MPPT) of 8 kW, a wind turbine of 10 kW, 138 pieces of 1 kW lead-acid batteries and a converter of 13.3 kW exhibited the most appropriate results. In this case, 41.8 % of the electrical energy to be obtained will be met from solar energy and 58.2% from wind energy, and electrical energy of 55,765 kWh will be produced annually. It has been determined that the initial investment cost of the system to be established is 405,536 ₺, the net current cost is 882,950 ₺, the cost of the electricity produced is 1.53 ₺/kW, and the investment will pay off in 9 years. In addition, it has been found that the amount of CO2 to be released into the atmosphere will be 17,358 kg/year if the required electrical energy is met from the grid.
