Design and Analysis of 2 DOF (Degree Of Freedom) Tracker Control and Mirror Light Reflection of Photovoltaic System

Solar Panel is an electrical energy source with a very clean operation, less maintenance , without emission. Recently, many researchers have been experimenting with the solar tracker to be able to optimize solar radiation absorption. For that, a solar tracker control system device using 2 Degrees Of Freedom is developed. Using this device, the photovoltaic panel is expected to be perpendicular to the sun, so the panel will be moved each time depending on the sun's position so the result will be much more precise toward the direction of the sun. The purpose of the paper is to design a device consisting of mechanical, program, , electrical design. Based on the test results, it can be concluded that the solar tracker control system with 2 DOF works according to the design. The system using mirror reflection can produce output power from the photovoltaic panel up to 1,75% more than the result produced by static condition of the photovoltaic panel with output power up to 1,43% and also the result of solar tracker control system with 2 DOF (Degrees Of Freedom) without a mirror that produces output power up to 1,73%.
