Maximum Power Point Tracking Methods Used in Photovoltaic Systems: A Review


Department of Electrical Engineering, Islamic Azad University, South Tehran Branch, Tehran, Iran


This paper reviews and compares the most important maximum power point tracking (MPPT) techniques used in photovoltaic systems. There is an abundance of techniques to enhance the efficiency of photovoltaic systems. The crucial distinctions between these techniques are digital or analog implementation, simplicity of the design, sensor requirements, convergence speed, stability, range of effectiveness and costs. Thus, opting for a suitable algorithm is vital as it affects the electrical efficiency of the PV system and lowers the costs by lessening the number of solar panels needed to get the desired power. Moreover, the paper provided a summary of the most used MPPT algorithms.
