Daftar Isi:
- Indonesia is a country that is passed by the equator so gets good radiance of sunlight. This sunlight can be converted into electrical energy by solar cells and produces enough energy to suffice the electricity needs of the people that most of them are now supplied by non-renewable energy sources. To optimize the electrical energy which is produced by solar cells, we need a tool that can orient the solar cells into the sun. Prototype of dual-axis sun tracker is a tool that is designed to direct the solar cells into the sun. Sun tracker works by using four sensors LDR (Light Dependent Resistor) and two Tower Pro MG90 servo motors as driver actuators. The system is controlled by arduino uno that run program which is implanted by Arduino IDE Integrated Development Environment) software. The result of outdoor testing showed the comparison of the open circuit voltage (Voc) and the short circuit current (Isc) of the solar cell that is mounted on a sun tracker to the fixed position solar cell. The solar cell that is mounted on a sun tracker produced open-circuit voltage 5.97% on average greater than the voltage that was produced by the fixed position solar cell and the highest comparison value was 8,73% greater . The short-circuit current production of solar cell on a sun tracker was 25.36% on average greater than the current of solar cell on fixed position and the highest comparison value that was got from the testing was 90,09% greater.
