This FollowSun project is based on a solar panel placed in a support with a stepper motor driving a wheel controled by a PIC microchip in order to turn the solar panel to where the sun shines the most every half an hour. This will exploit the solar panel resources for supplying at every moment of the day the most current and voltage.

Step 1: Create a Support for the Solar Panel

Step 2: Make a Power Interface

For this interface we used:

1 LF347 Operational Amplifier

4 TIP41 NPN transistor

4 10k Ohms Resistor

4 2.2k Ohms Resistor

This interface will avoid loading effects oin the PIC

Step 3: Select the Motor

We selected a bipolar stepper motor of 6 wires at 12 volts in order to move the support of the panel.

    Will you be adding some info on the mechanism that moves the solar panel? This looks interesting!

    Yes, we were selecting among several motors but finally we chose a 6 wired stepper motor.
