A grid-connected Photovoltaic system with the functionality of maximizing power capability and increased the power rating is introduced in this work. Increasing interest and investment in renewable energy gives rise to rapid development of high penetration solar energy. There are multiple-choice to interface PV arrays with the utility grid. The topology of a single stage (PV) system with two MPPT techniques to increase the power capability is developed; it is suitable for grid connected system. However, output of solar arrays varies due to change of solar irradiation and weather conditions....
