Abstract
Sunlight is one of the energy that can be used to generate electricity. Converting solar energy into electrical energy required a device called Photo-Voltaic (PV). However, output of PV hardly depends on the position of PV to the sun. The maximum PV output will reach when the sun position perpendicular to the surface of PV. Therefore, the device that can track the position of PV is needed. The aim of this research is to design a track solar system using Arduino and LDR sensor to follow the sun movement. This method will be applied to a 80 Wp solar panel. The output of the tracker solar system was compared to the fixed PV. The result shows that the output voltage of the tracker solar system reached 18. 81 V that was higher than the fixed PV about 18,56 V and the output current of the tracker solar system reached 4,27 A that was higher than the fixed PV about 4,19 A.

IntroductionAll people use energy to meet basic human needs such as lighting, cooking, comfort of space, mobility and communication and to serve productive processes
Human needs for energy continue to increase in daily life as a way to increase human potential that leads to social, economic and economic growth welfare and health. all people use energy to meet basic human needs such as lighting, cooking, comfort of space, mobility and communication and to serve productive processes. [1][2].Renewable energy is all forms of energy both from the sun, geophysics or biological sources that can be quickly recovered by natural processes at the same level as or exceeding the level of their use
Renewable energy is obtained from recurrent energy flows that occur in the natural environment and includes resources such as biomass, solar energy, geothermal energy, hydropower, tides, and waves. [3][4] One of the renewable energy that has been developed in Indonesia is solar energy
Summary
All people use energy to meet basic human needs such as lighting, cooking, comfort of space, mobility and communication and to serve productive processes. Renewable energy is all forms of energy both from the sun, geophysics or biological sources that can be quickly recovered by natural processes at the same level as or exceeding the level of their use. The position of the sun and the position of the region on the surface of the earth have a real influence on the potential of solar energy in an area. The geographic location of Palu City has the potential to receive high levels of sunlight. This condition is suitable for utilizing solar energy to produce electricity
