Abstract

Solar energy is one of the popular renewable energy nowadays. It is consider as total free and clean energy source since the sun is estimated still able to exist for more 5 years. Malaysia is a place suitable to develop solar technologies because of the climate of the Malaysia which is sun all long year; the sun light intensity does not vary by season. In addition, some natural resources like fossil fuels is consider as short-term resources because it is estimated will finished in next 30 year. Based on this situation, renewable energy like solar energy is essential to human being after the natural resources is finish. The fact is, conventional solar panel power system is stationary, means the solar panel will not always facing to the direction of sun, this make the light intensity falling on the solar panel is not in maximum level so the solar panel will not always work in its maximum performance. Besides, the smart phone and tablet has become a trend to young generation in the last few years, user normally charge up their electronic devices in home or car by using non-renewable energy source. In this project, a prototype of microcontroller-based small scale solar charger will be built to allow user to charge up their electronic device by using totally free and clean energy and maximize the performance of the solar charger by combine it with a solar tracker, which solar tracker will align the solar panel to the direction of the sun so that the solar panel will always perpendicular to the sun with the help with microcontroller, sensor and DC motor. This method enable the solar panel work in maximum performance because the light intensity falling on the panel will be in maximum intensity level in all long day. A solar tracker and charger system is designed and experimentally tested. The information and design detail are shown in the report.
