The performance of the configurations is evaluated by comparing the open-circuit voltage, the short-circuit current, the maximum power point (MPP), the voltage and current corresponding to MPP, and the Fill Factor (FF). The variations of the series resistance and the shunt resistance of a PV module under different irradiance levels are also determined by considering the effect of thermal voltage. Finally, a comparison between the performance losses in the different configurations is presented. The results of this study show that the parallel configuration has the best performance under the conditions of partial shade in the context of this work.展开更多

Before using such energy sources, the very important thing is analysis at the basic level. This paper presents analysis and realization of solar PV system. The current-voltage and power-voltage characteristics of solar PV array changes as parameters like solar insolation, and temperature changes. These characteristics are found and realized by using MATLAB software.展开更多
