Renewable energy sources should be expanded instead of fossil energy sources due to their environmental damage and exhaustion property. Especially, unused roof areas in agricultural production plants are good options for electricity generation using PV panels. In this research; theoretical, practical and technical solar energy potentials were determined; the amount of electricity that can be produced and carbon emission amounts that can be reduced by PV panels were found using PVsyst and RETScreen software in 6 different designs for the roof area of Grape Products Processing Plant in Tekirdag Viticulture Research Institute. The average consumed energy during grape juice production period was determined as 4059,822 kWh. As a result of this research, the technical solar energy potential was found as 1543 kWh/m2 annually with acceptance of panel angle as 20⁰ and the azimuth angle as 0⁰. Performance ratios for monocrystalline (mono-si), polycrystalline (poly-si) and amorfcrystalline (a-si) PV system designs were calculated as 85,15% - 84,39% - 80,40% while annual electricity generation values were calculated as 1219-1280-1291 kWh/kWp/year, respectively. It was seen that greenhouse gas reductions can be achieved as 10.9 tCO2/year in case of generation of 23.1 MWh electricity per year (mono-si) ; 10.5 tCO2 /year in case of 22.4 MWh electricity generation (poly-si) and 4.9 tCO2 /year in case of 10.3 MWh electricity generation (a-si). It was found that designs using a-si panel type are not suitable due to the limited roof area of the plant while designs using mono-si and poly-si panels provide approximate outputs in terms of cost and efficiency.
