ABSTRACT
Technical researches on solar Photovoltaic (PV) systems including its technological development and advancement have displayed tremendous growth in the last few years, making them commercially achievable but not really affordable currently. It is because of this challenge of non-affordability that has led to the development of maximum power point tracking of solar energy for its maximum efficiency and effective utilization. This work is on review of maximum power point tracking (MPPT) techniques for PV systems including its design, characteristics, principles of operations, construction, planning of PV arrays and the necessity of such systems. Various techniques reviewed in this study include offline, hybrid, three points, temperature based, Artificial intelligence (AI) control as well as the fuzzy logic control techniques. The offline techniques include open circuit voltage, short circuit current and look-up table. Perturbed and Observed method (P&O) as well as the incremental conductance controlled method is among the hybrid technique reviewed. Also considered is this significance of Irradiance and fill factor to MPPT technology.
