Solar Powered Battery Charger 
Project Idea
Build an eco-friendly charging system using solar energy to charge rechargeable batteries. This project uses a solar panel to convert sunlight into electrical energy, which is then regulated and used to safely charge batteries like 18650 Li-Ion cells. It’s ideal for outdoor use, emergency preparedness, or learning renewable energy principles in a practical, hands-on way.
 
Project Description
This project is a portable solar-powered battery charger designed to harness sunlight for charging small rechargeable batteries. A solar panel provides DC power, which is regulated using a charging controller module like TP4056. The system includes a battery holder to accommodate batteries, a blocking diode to prevent backflow, and an LED indicator for charging status. It’s a compact, low-cost solution that introduces solar power basics while promoting sustainability. The charger is suitable for small gadgets, LED lights, and other low-power applications.
