The solar energy is stored in the battery in the form of DC from solar cells with the help of battery charging circuit. The charging circuit is made up of IC 7812 voltage regulator and two transistors BC547. That DC voltage is then fed to the voltage regulator IC 7812; the output will be regulated to constant 12V.
