Analysis of three grid connected photovoltaic power plants with pvsyst program; sample of kilis

Abstract

In this study; energy production values of three photovoltaic power plants in Kilis City and created systems by PVsyst simulation program and having same characteristics with the said power plants were analyzed. Energy production data generated by the simulation report and the production data of the power plants for three years were compared. Also; the average data of the power plants for the last three years was compared with data of EİGM. Panel and inverter information of these power plants ant annual average temperature and radiation data of coordinates of the power plants were used in the PVsyst simulation program. Meteorological data of locations of the power plants were produced synthetically with Meteonorm 7.3. in the simulation program database. The plants analyzed; they have 1040 kWp, 1029 kWp and 1000 kWp installed power values. To understand the analysis result well; the power plants were selected at close power values and production data for last three years were used. As a result of comparison, it was seen that the data obtained were close to each other but the power plants productions values were less. This difference; changing temperature depending on weather conditions, cloudy days, unimaginable weather events, snow, dust etc. accumulated on panels it is caused by the reason. The study; it is aimed to be a guide for people and institutions planning to invest in this field.
