A schematic diagram of the solar battery charging circuit. The battery is charged when the voltage of the solar panel is greater than the voltage of the battery. The charging current will decrease as the battery gets closer to being fully charged. This is just a simple circuit, and there are many other ways to charge a battery from solar power.
Constant Voltage Charging: This strategy involves maintaining a constant voltage across the battery terminals during the charging process. This is a simple and effective approach, but it can result in overcharging if the voltage is set too high .
