Abstract :The performance of panels for PV system design is determined according to the performance values in standard test conditions specified in the panel catalog, without knowing the performance under actual operating conditions. However, the operating performance of the PV panel depends on meteorological characteristics of place where the PV system is installed. Especially, if outside temperature values are above test conditions, the efficiency of the PV panel decreases and generation losses are observed. In this study, performance parameters of photovoltaic panel were calculated for four different PV panel technologies only by using their catalogue values like NOCT temperature, power-temperature coefficient etc. For this purpose, real working conditions were simulated using 3-year climate data for the meteorological conditions of Sanliurfa, Turkey. In the end, PV panel efficiency, electricity generation values and performance ratios were calculated in accordance with the temperature. According to the results obtained, the PV panels’ performance ratios decreased up to 0.75 during the summer months. The highest unit energy generation was achieved with thin film PV technology.
