Feasibility Study of Photovoltaic System that can be Applied to Tekirda? Nam?k Kemal University Ziraatbiyotek Building using RetScreen Program

Abstract

As a result of the rapid decrease in fossil fuels and increasing energy demand, countries have turned to alternative energy sources. Renewable resources, which are alternative to fossil resources and are environmentally friendly, are clean and inexhaustible energy resources. Solar energy is one of these alternative energy sources This study; With the RetScreen program, it is aimed to analyze the suitability of the system and observe its performance before the PV system is installed. Features affecting the performance of PV systems; It has been designed by considering factors such as the position of the panel, the angle of inclination, shading and panel type. Shadow analysis was performed with the Helioscope program. In the shadow analysis, firstly, the geographical location is defined and the determined parameters are entered into the system. Technical, energy and economic analysis of the 14 kW solar system for the Ziraatbiyotek building was made. The analysis was made in 2 different scenarios and the positive and negative aspects of the solar system to be installed in the building were revealed. The Ziraatbiyotek building, where the study was carried out, was established in the Naip District of the Süleymanpasa district of Tekirdag province. For the Ziraatbiyotek laboratory building, 60 panels of the GES power plant with an area of 405 m(2) were used. The brand of the selected panel is Astronergy Solar and each has a power capacity of 240 W. The panel inclination is 30 degrees and the azimuth angle is 0 degrees in the RetScreen program. Polycrystalline was used as the panel type in two different scenarios. In the first scenario, emission reduction support was not included and the payback period of the system was 10.4 years, and in the other, $15 tCO(2)(-1) and annual support of $142 were included and the payback period of the system was 9.8 years. According to the results obtained with the program, 20.1 Wh energy produced by the solar panel system decreased 9.5 tCO(2) greenhouse gas emissions. It has been obtained that if a 14 kW solar energy system is installed in the Ziraatbiyotek building, approximately 40% of the annual electricity need will be met from solar energy.
