Depletion of non-renewable energy sources with the increasing demand in electricity and also to avoid islanding condition an efficient and sustained source of energy becoming mandatory. This paper focuses on mathematical modeling and simulation of PV module with boost converter interconnected with AC Load. MPPT algorithm named Perturb & Observer technique is implemented in boost converter to extract maximum possible power from PV module which in turn depends on solar irradiance and temperature. This work lead to utilize the renewable solar energy at a large scale by interconnecting PV module and AC Load while extracting constant maximum power from module. This paper will review existing approaches on MPPT algorithms. PV module of 5.5 kw is converted into AC and fed to AC Load. P-V and I-V characteristics are obtained by modeling mathematically for data sheet “Sun Power SPR-305-WHT-U Solar panel in MATLAB code. The output waveforms for power output from PV module before and after implementation of MPPT algorithm are analyzed through MATLAB Simulation.
