Abstract

Solar panel has been used increasingly in the recent years in converting the solar energy into electrical energy. The solar panel can be used either as a stand-alone system or as a large solar system that is connected to the electricity grids. Nowadays, humans are trying to consume more energy from the sun using solar panel. In order to maximize the conversion from solar to electrical energy, the solar panel has to be positioned perpendicular to the sun. Thus, the tracking of the sun’s location and positioning of the solar panel is important. The goal of this project is to design a sensor-less solar tracking system, which can locate the position of the sun. The tracking system will move the solar panel so that it is positioned perpendicular to the sun for maximum energy conversion at all time. The method used in the system was based on the Falaq's knowledge in determining the Muslim's prayer time. This method will ensure the solar panel always follow the movement of the sun in order to produce the maximum energy output. In this project, the solar tracker is able to move in horizontal axis without using any sensors. The system consists of Arduino microcontroller, LCD display, motor driver, and a solar panel. This system produce more output energy than conventional solar panels without tracking systems and provides lower cost compared to a solar tracker system that uses a sensor. This system is the new technology introduced which is able to give a good impact to every consumer who is concerned about the performance of the solar panel.
