An imperative role of sun trackers in photovoltaic technology: A review

The efficiency of the photovoltaic (PV) system is directly proportional to the solar energy. The maximum efficiency from the PV systems can be achieved if the panel is kept perpendicular to the direction of the radiations of sun. Hence, in order to achieve maximum concentration, radiation and efficiency of the PV cell, tracking of the position of the sun with accuracy is extremely important. The various methods of sun tracking system have been...
