Photovoltaic (PV) technology is becoming increasingly prevalent. The popularity of solar PV technology stems from the fact that it has no negative environmental impact and generates energy from a renewable resource. i.e., sunlight. Although PV cells do not create any hazardous issue for the environment but due to various reasons, they are able to produce only a moderate amount of electrical output. Although researchers have developed PV cells with efficiencies up to 50 %, yet most of the commercially available Solar PV panels convert only 15-20 % of the insolation into electrical energy. Main problems faced might be due to poor weather conditions, partial shading, and many others. Maximum power point tracking (MPPT) is a methodology used in photovoltaic systems to extract most power out of the cells. The paper explores the implications of several investigations performed on the problem of attaining the maximum power point (MPP) in a photovoltaic system. The parameters observed are convergence speed, implementation complexity, parameters sensed, and True MPPT.
