Week 4 (FYP2) : Constructing the Solar Charging Circuit

On 30 September, i tried to construct the solar charger circuit on the breadboard.

Picture above shown the open circuit voltage for the solar panel. The solar panel was rated at 2W. 

This was the voltage produced by the 12V 7.2AH. The circuit was in dumping mode, which means the battery was not connected to solar panel.  

This was the voltage produced by the solar panel, note that the RED LED was ON, which means the circuit was in dumping mode. 

This picture shown the voltage produced by the solar panel, which was used to charge the battery. The circuit was in charging mode, which was indicated by the GREEN LED. 

The circuit was forced to be in dumping and charging mode by pushing the push buttons.
