This paper presents an observation of the performance of a solar PV system under high temperature in a hot climate area. The main objective of this work is to observe the effect of high temperature on the efficiency of a 13.2 kW rooftop system and to analyze the relative technical parameters with and without a direct current optimizer (DC Optimizer). In such climates, the impact of high temperatures on the performance of solar system should be taken into consideration to get the intended output power. The average amount of solar radiation falls in this area is around 2200 kWh/m2. The simulation results are done using PVsyst software which shows the amount of energy produced yearly, the amount of loss of energy, the carbon emissions that have been reduced and the performance categories. The 13.2 kW system without DC optimizers can produce 24190 kWh/ year at performance ratio of 77.66 and a tilt angle of 25°, latitude of 24.70°, longitude of 46.68° and altitude of 450m. The system with DC optimizer produces 24640 kWh/ year at performance ratio of 79.06. In this case, it is obvious that optimizers can increase the output power up to 1.83% and can be higher in other cases. The effect of temperature cause both systems to have 14.21 % of loss per system which shows that optimizer is also affected by the increase in temperature. [ABSTRACT FROM AUTHOR] |
