Design of a Solar-Powered Mobile Phone Charging Station for Rural Markets in Yobe State

Mobile phone penetration in rural Yobe State, North East Nigeria, has grown substantially over the past decade, yet access to reliable electricity for device charging remains acutely limited in market towns and farming communities. This project documents the design and fabrication of a solar-powered mobile phone charging station suitable for deployment in rural markets, enabling community members to charge devices at a nominal fee. The design brief was developed through consultations with traders, market committee representatives, and mobile phone users in Potiskum and Damaturu local government areas. Key requirements identified include capacity for simultaneous charging of a minimum of twelve devices, compatibility with multiple charging cable types, weather-resistant construction, anti-theft cable management, and aesthetic integration with the market environment. The charging station structure is fabricated from galvanised steel with a lockable control unit and a roof-mounted photovoltaic array providing sufficient power for continuous operation during daylight hours. Charge control circuitry prevents battery overcharging and includes an indicator panel showing available charging capacity. A prototype station was deployed in Potiskum main market for eight weeks, serving an average of forty-seven users per day and generating revenue sufficient to offset fabrication costs within fourteen weeks. User satisfaction surveys confirmed high service value and demand for permanent installation. The project recommends replication through the Yobe State Community and Social Development Agency.
