Photovoltaic cell converts solar energy directly
into electricity. This paper describes a design of a charge
controller to get the maximum power by using the Pulse
Width Modulation (PWM) technique. In this paper PWM is
controlled by the PIC Microcontroller. The work of the
paper is to charge a 12 volt battery by using a 50 watt solar
panel with maximum power. In this paper how maximum
power can be achieved from solar panel to charge the
battery through PWM signal generated by microcontroller
is discussed and the experiments by taking voltage and
current’s values in different time interval are shown. Finally
the experimental results are illustrated in this paper.
