In this paper, electricity demand of a multi-functional agricultural farm is analysed. The farm is located around Ankara and spreaded over 4000 da and installed 400 kW power in electricity. The electricity demand of the farm is simulated by PVsyst in order to comparison the most used three different PV structures for a grid-connected operating type of PV system in the terms of electrical performance indicators. The paper aims to identify the most compatible PV structure for Ankara and its environments. All meteorological and environmental conditions and BOS equipment in three simulations are identical. Many electrical and operating performance indicators are examined in order to compare each other. System efficiency is similar in both c-Si and mc-Si types (~12 %) but the lowest rate in a-Si (5.5 %). As close to system efficiency, special production of the system is the biggest for a-Si, 1689 kWh/kWp/year; second for c-Si, 1607 kWh/kWp/year; the lowest for mc-Si, 1570 kWh/kWp/year. The average per kWp of electricity generation (system yield) is 4.40 kWh/kWp/day for c-Si; 4.30 kWh/kWp/day for mc-Si; 4.63 kWh/kWp/day for a-Si simulations. Although a-Si one's system efficiency is less than others, it is more profitable for Ankara environments. Material and method used in the study is quotation from a doctorate study called "Determination of Solar Energy Potential and Using Possibilities for Research and Application Farm of Agricultural Faculty of Ankara University in Haymana" which is completed in Graduate School of Applied Science of Ankara University in 2010.
