ABSTRACT

This paper presents the design and prototype of a charging station powered by solar PV. It provides power to charge AC and DC consumer portable devices such as laptops, cell phones etc. It can be used at schools, hospitals, parks, bus stops, emergency locations etc. The station has 2 AC and 4 DC outlets which can charge 6 devices simultaneously. The system overall efficiency obtained from testing is 76.8%, which is satisfactory for solar-inverter systems. In a very cloudy day, when all 6 outlets are used to charge two laptops, three cells phones and a tablet with the total demand of 247Wh, the system could be sustainable for 2.6 hours. The system could power the average worst-case load of 155W for 4.1 hours. For better sun days, the system is likely able to supply power for a longer time. The system is portable, weather-resistant, versatile unit that can easily be expanded.
