In modern day’s necessity of electrical power increased with increase due rapid industrial growth. With depletion of conventional energy sources, renewable energy sources started to play a crucial role among which solar is quiet important. When these are interfaced with grid many power issues are raised. This paper proposes a single phase single stage scheme for grid interfaced solar PV generating system. A simple filter is designed to exempt the services of PLL to facilitate the extraction of real component of load current and this reduces the system dependence on proportional-integral(PI) controller tuning which in turn improves the dynamic response of the system and makes  the system quiet robust.
