Development of a solar system for charging mobile phones with cus-tomized DC chargers for rural areas in Nigeria

The introduction of mobile phones has redefined the world of communication in that it has turned the world into a global village as people can now make contact through phone calls within and across countries at affordable rates. Nowadays, almost every homehas a functional mobile phone, be it a conventional, android, or iPhone, among others. These phones use non-self-charging rechargeable batteries that need to be recharged from time to time to meet the demands of the users. However, access to a reliable source of power to meet the energy demand, including mobile phone charging needs, of off-grid rural dwellers remains a global challenge. As a result, this study designed and im-plemented a solar-powered mobile phone charging system with customized DCchargers for use in remote off-grid areas. The test results showed that the system is very effective for charging mobile phones.
