PERANCANGAN KINERJA OPTIMALISASI PV(PHOTO VOLTAIC)MENGGUNAKAN LABVIEW BERBASIS ARDUINO

Abstract

At present the majority of electricity generation in Indonesia uses non-renewable energy sources, while renewable energy sources are still very minimal. Therefore, the use of renewable energy sources needs to be improved. strive to improve the quality of the electricity produced. one of the efforts to improve high reliability and stability is to design a solar tracker system. In this case discussing the design of a technical solar tracker to increase the energy produced by photovoltaic, the solar tracker system component consists of: PV module, 12 V dc motor, and LDR sensor on the results of 1 fruit photovoltaic module design with module capacity 20 wp. And the power generated by dual axis solar tracker, is always greater than that produced by static solar cells. At 12:00 WIB, the power generated by dual axis solar tracker is 9.65W, while the static generated solar cell power is 6.88 W. There is a difference in the output power of 2.77 W between the dual axis solar tracker and solar cell static, or It can be said that dual axis solar tracker has increased output power by 40% compared to static solar cell. Besides that the optimal voltage occurs at temperatures of 32.22 ° to 36.09 ° with an angle of 41.41 ℃ to 28.35 ℃, at 09:30 until 14:45 with an average voltage of 15.27 V to 18.29 V. To control this system using the Arduino Mega based labview. This Arduino controller is done by Labview as the output display and Arduino as the main controller.
