Renewable energy is becoming more attractive because of increasing power consumption. Particularly, photovoltaic converters or solar cells are the most important among them. It is because they have many advantages like low weight, feasibility for small scales and greener impact on environment. But still, two main drawbacks exists, which prevents its tremendous growth. They are unstable output and expense of the system. So it is important to absorb the maximum solar energy in order to increase the efficiency of the solar cells, by which we can eventually overcome this drawback. So, this paper proposes solar tracking and mppt tracking system combined with IEDM in movable photovoltaic system. Perturb&Observe and Incremental Conductance MPPT algorithm were used for the MPPT tracking. And it can be experimentally verified by modelling the PV system with MPPT algorithm in Matlab/Simulink Software. According to the environment, it monitors various variables, and performs optimal energy management to maximize the efficiency of solar cells. This system is not using any external sensors for detecting the best location of panel under sunlight and just by measuring the output voltage of solar cells, the controller finds the best position.
