PERANCANGAN DUAL AXIS SOLAR TRACKER BERBASIS KENDALI LOGIKA FUZZY MENGGUNAKAN ARDUINO

Abstract

The need for electrical energy is increasing, while the source of available electricity is limited. For this reason, a renewable energy source is needed to meet electrical energy needs. Solar energy is one of the renewable energy sources used to produce electrical energy, using solar cells. In general, the solar cell is positioned with the orientation of the panel surface facing the equator, with a slope between 10 to 15 degrees and in a static state (fixed). This condition has not been able to absorb solar energy optimally throughout the day. Based on this condition, a dual axis solar tracker is designed based on fuzzy logic control using Arduino. This dual axis solar tracker operates with the input of four LDR sensors. At the output, two DC power window motors are used as actuators to adjust the position of the solar cell based on sun’s position. The total power generated by dual axis solar tracker, if we calculated based on the power generated every hour for one day is 49.58 W, while the power generated by static solar cells is 24.05 W. It can be seen, that dual axis solar tracker can produce output power 2,06 times greater than power output which is produced by static solar cells.
