Abstract: Photovoltaic (PV) is a technical name in which radiant (photon) energy from the sun is converted to direct current (DC) Electrical Energy. PV power output is still low, continuous efforts are taken to develop the PV converter and controller for maximum power extracting efficiency and reduced cost factor. The maximum power point tracking (MPPT) is a process which tracks one maximum power point from array input, varying the ratio between the voltage and current delivered to get the most power it can. A number of algorithms have been developed for extracting maximum power. This paper details with the study of PV system with MPPT algorithm. The panel voltage V and its generated power depend on the number of serial modules in a string and the number of parallel strings in a panel. The module reference voltage VREF is obtained from the irradiation density A and the MPPT algorithm in order to extract the maximum power.
