Comparison of Charging and Usage Efficiency of Portable Fan Batteries Using Grid Electricity and Solar Panels at Different Times

Abstract

The provision of sufficient energy to meet human needs is severely hampered due to the lack of energy sources. Solar panels as one of the tools to design alternative power plants that can be used to capture sunlight and can be an alternative to energy sources. This research aims to provide a clear picture of the efficiency of using solar panels as an alternative energy source when compared to PLN’s electrical energy source, as well as to identify the fastest time to use solar panels and the most effective time to charge using solar panels. In this study, a comparative experimental method was carried out, namely solar panels placed in the sun with different time conditions, namely in the morning, afternoon, and evening. The time obtained in the three conditions is 5400 s, 14400 s, 16200 s, and the average time of charging using PLN is 7574.6 s. The results obtained by this study include charging portable batteries more effectively on solar panels than on PLN, and maximum charging during the day.
