OPTIMASI SUDUT KEMIRINGAN PANEL SURYA JENIS MONOKRISTALIN DAN POLIKRISTALIN DI WILAYAH KOTA PRABUMULIH

The tilt angle of the solar panel is one of the factors that affect the performance of the solar panel considering its function is to maximize the reception of solar energy radiation. Therefore, it is necessary to study the potential of solar energy and optimize the reception of solar radiation by maximizing the tilt of the solar panel. This research will simulate and optimize the angle of the monocrystalline and polycrystalline solar panels by utilizing the potential of solar energy in the Prabumulih City area. Based on this data, data will be collected from solar cell panels which include solar radiation data, and the resulting power output at each variation of the tilt angle of 1º, 3º, 5º, 10º, 15º, 20º, 25º, 30º, 35º, 40º, and 45º. The purpose of this study was to determine the most appropriate tilt position of the solar panels on the efficiency of the solar panels. The research method used is to simulate the tilt angle of the solar panels which is carried out using variations of the tilt angle of the solar panels using RETScreen Expert software. From the simulation results of the monocrystalline and polycrystalline solar panel tilt angle using RETSreen Expert that has been carried out, it is obtained that the tilt position of the solar panels and different output power is obtained, the simulation results of the monocrystalline type solar panel tilt angle is 1º with an output power of 230,492 kWh per year and solar panels polycrystalline is 3º with an output power of 215,608 kWh per year.
