In this paper, we study the proposed structure including solar energy, battery, and super-capacitor using a novel fuzzy controller. Due to the changes in the output power of solar panels, it is necessary to reduce oscillations and harvest smooth DC link voltage. Due to the nonlinear current-voltage characteristic of the solar cell, for its optimal use, it is necessary to track its maximum output power at any time. Also, a battery is employed when there is a need for more power in the output load. Capacitors are used for instantaneous times and batteries for longer periods to power output loads. An Intelligent Maximum Power Point Tracking (MPPT) procedure using Fuzzy Control for Photovoltaic (PV) stand-alone system has been introduced. The simulation is performed in MATLAB / Simulink software and the output results confirm the accuracy and validity of the system.
