Abstract

Recently, the use of electric vehicle increases significantly worldwide including in Indonesia. However, this trend is in contrast with availability of an electric vehicle charging station. Since Indonesia has a huge solar energy potential, it is possible to build a solar powered electric charging station. Various parameters that affect the performance of the solar panel have to be considered. The present work is performed into two parts, i.e. the first part is investigation of performance of the photovoltaic (PV) panel at tilt angle of 5, 10, 15, 20, and 25 and the second part is the investigation of performance of the PV panel without and with water cooling at optimum tilt angle obtained from the first part. Data collection is performed from 9 am to 2 pm for 5 days. The results show that the optimum tilt angle is found to be 20 with maximum conversion efficiency of 21.02%. Meanwhile, the water spray cooling of the PV module’s surface can improve output power at the rate of 9.1%. The scientific innovation of the present work is the development of electric bicycle charging station with energy source from solar energy which is renewable and clean energy.
