Electricity demand is growing with highest rate for the energy consumed worldwide. Thus the mankind is facing a massive challenge of never ending increase in energy demand. Photovoltaic energy is one of the most important energy sources since it is clean and inexhaustible. It is important to operate PV energy conversion systems in the maximum power point to maximize the output energy of PV arrays. An MPPT control is necessary to extract maximum power from the PV arrays. The aim of MPPT to control the voltage of solar panels in the influence of variation in atmospheric conditions. In recent years, a large number of techniques have been proposed for tracking the maximum power point. This paper presents a deep review and comparison of different MPPT methods and proposes one which used a power estimator and also analyses their suitability for systems which experience a wide range of operating conditions.
