Development of A Cost-Effective Rechargeable 5V Solar Lamp

Millions of people living in rural areas around the world lack access to reliable and affordable lighting. Their reliance on traditional lighting sources poses health risk, environmental concerns and economic burdens. Energy poverty persists, highlighting the need for sustainable energy and affordable lighting solution. This study presents the design and construction of a cost-effective rechargeable 5V solar lamp, tailored to meet the lighting needs of rural households. The construction of the lamp began with the assembly of all the components such as battery, solar cell, light emitting diode (LED) and connecting wires, all coupled and soldered to a TP4056 module and then enclosed in a P-box to provide a secure and safe housing of the internal components. With its durable construction, efficient energy conversion, reliable performance and low maintenance requirements, this solar lamp offers a viable, attractive and sustainable lighting solution for off-grid communities. This study contributes to environmental conservation and improved energy access for rural households and provides valuable insights for the development of cost-effective and sustainable solar-powered lighting solutions by reducing reliance on traditional lighting sources.
