Solar Energy-Powered Multiple Cellphones Charging (Booth)

The work present the development and implementation of a solar powered multiple cell phones charging system (booth) for 50 cell phones that is capable of charging multiple phones including laptops 24 hours without supply from the main grid. The  work is a stand-alone solar renewable energy system that can be used in urban and rural areas with the aim of solving the problem of phone as at when due, due to power failure from main grid or where there is no electricity at all. The system hardware is consists of Solar panel, charge controller, deep circle battery, inverter and multiple charging outlets. The solar panel converts the sun energy to direct current electrical energy to charge the battery through the charge controller. The charge controller controls and regulates the voltage from the solar panel to the battery and also monitors the charging process to avoid over charging of the battery. The battery stores the energy from the sun and supplies it to the input of the inverter. The inverter inverts or converts the direct current (DC) to an alternating current (AC). The 220VAC at the output of the inverter is connected to the multiple socket outlets where phones and laptop is connected for charging.
