New optimally technical sizing procedure of domestic photovoltaic panel/battery system

This paper describes a new sizing system of a solar array and a battery in a standalone photovoltaic system. The method consists in a fuzzy logic system that reads the consumed energy and the monthly average of daily solar radiation of the region in the input and gives the photovoltaic panel surface and the battery capacity in the output. The simulation results are based on Matlab/Simulink. The system performance with different inputs has been verified by carrying out simulation studies using calculated outputs. The results demonstrate the effectiveness of this approach. In fact, an example of a domestic house is provided in this paper, where the simulation results show good performances.
