In this model, a single axis, single junction silicon solar array is modeled together with a Maximum Power Point Tracking (MPPT) controller, a solar tracker, a battery pack and a speed controlled AC motor.A solar tracker was implemented with the purpose of minimizing the angle of incidence between the incoming light and the solar array. Inverse kinematics was performed to determine the ideal movement profile. The simulation video shows the solar tracker at work.For any given set of operational conditions, solar cells have a single operating point where the maximum power output can be obtained. The purpose of an MPPT controller is to sample the output of the solar cell and adjust the voltage to obtain this maximum power for any given environmental conditions. The commonly used “Perturb and Observe” method is modeled. The controller perturbs the voltage by a small amount and measures the power, if the power increases, further adjustments in that direction are applied until the power no longer increases. . By adding a MPPT controller to track and control the photovoltaic voltage, the efficiency can be significantly improved.
