A Solar tracker is a device that is powered by solar panels motors, aiming to adjust the position of the panel with the movement of the sun so that energy can be absorbed optimally. This study will compare the use of solar panels and solar trackers fix the model, so on getting the efficiency of each system. The test site is on the campus of the Institute of Technology of Sumatra. Prototype solar tracker is controlled using a microcontroller Arduino, ethernet shield as a liaison Arduino with local networks that can be connected to the web, the stepper motor is used as a driver, is equipped with a voltage sensor, current sensor, the sensor LDR (Light Dependent Resistor) for parameter tracking the sun, solar charge controller as control the charging and battery as energy storage. Parameter solar energy tracker and fix displayed realtime models consist of the reading of voltage, current, and power in the form of a graph on a web monitoring. Calculation of energy that can be generated a model of solar tracker is the difference between the energy stored in the battery is reduced by the energy to activate the motor driver, so we get solar tracker models to use efficiency as compared to fixed models. © 2020 Published under licence by IOP Publishing Ltd.
