In this paper, operation and maintenance cost effect of PV array and battery on optimal sizing of PV and energy storage capacity in a grid-connected house is analyzed. The mentioned cost is applied in objective function of studied system. The objective function also is made of other different costs including annual cost for purchasing electrical energy from grid and annual investment cost for system components and others. To exchange of energy between house and grid four modes are considered and finally, optimal sizing of PV capacity and energy storage will be obtained. A numerical method named direct search is used to optimize objective function.
