Design and analysis of solar cell systems 100Wp in the Study Program Laboratory Electrical Engineering UHN Medan

Abstract

Currently, the use of solar cells is being developed as an alternative source of electricity generation. Studies and research are constantly looking for ways to increase the efficiency of using solar cells. This study aims to provide information to students of the Electrical Engineering study program at UHN Medan about the design, manufacture, simulation of the ETAP program, technical and economic analysis. Electrical load capacity in the laboratory room with daily load of 45Wh and peak load of 82 watts. Then the recommended designs are: 100Wp solar panel, BCR 40A, 102Ah battery and 1500VA inverter. The total cost required for the investment period is IDR. 18,954,000. Observations were made by taking light intensity data that occurred for 4 days in the laboratory. The equipment used for this measurement is: a luxmeter for measuring light intensity and a digital multimeter for measuring currents and voltages. The results show that. when the intensity condition is 49.0Klux, the voltage is 12.08VDC and the current is 0.47A. The highest light intensity occurs on the day of August 14, 2020 between 13.00-13.30WIB of 93.0Klux producing a voltage of 12.09VDC and an electric current of 0.90mA.
