Solar or photovoltaic (PV) system is an alternative clean energy resource that has received much attention in the research and industries. The solar charge controller is the main part of a solar system. There are three types of CC are MPPT, PWM and ON/Off. MPPT is getting very much popularity nowadays for its high capability of power extracted from a solar panel. The MPPTs controllers are used to ensure a high PV system performance. This research paper explains the development of a new algorithm for MPPT in large PV systems under partial shading conditions (PSC). The new technique is a combination of Fuzzy logic and PID. The methodology can be simulated in for different PV configurations under varying conditions. The integration of Fuzzy with PID controller is shown to yield faster convergence to the global maximum power point (GMPP) as compared to reference work. In our research work, DC voltage approximately 530V whereas in base work 40V. A novel maximum power point tracking scheme for PV power generation system under partially shaded condition gives a superior result as compared to reference work.
