This paper presents the use of sunlight trackers to increase the efficiency of solar panels. The sunlight tracking is done by passive and active tracking method with one or two axis. The active trackers use an electrical motor as a driver and can be controlled by a microcontroller or a programable logic controller (PLC) according to the direction of sunlight. The use of this controller in sunlight tracking system performed in real time or periodically. The position of the sun as a controller
