At this moment, the major obstacle of wide PV system commercialization is the high initial investment cost that stems from the strict grid connection standards and high expectations from the PV system [2], [3]. The grid-connected PV system consists of two parts: PV arrays that convert irradiation to electrical energy, and the converter that feeds the energy into the grid.
