Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: It should be low cost. Layman friendly, and easy to build. Must be efficient enough to satisfy the fundamental battery charging needs.
Below is the circuit diagram for it. The solar cells positive terminal is connected through the diode to the positive terminal of the 1.2V battery. If the voltage of the solar cell drops below 1.4 volts then with the 0.2V the blocking diode takes there wont be enough potential to charge the 1.2V battery.

To be able to control the voltage from the solar panel usually a voltage regulator circuit is employed relating to the solar panel output and the battery input. This circuit ensures that the voltage from the solar panel by no means surpasses the safe value needed by the battery for charging.
For any 12v 4.5AHr battery, the charging current is going to be 375mA for Half of the day and a bigger solar panel is going to be necessary.
