The Single Axis Solar Tracker follows the sun across the sky to collect as much energy as possible. It features a main solar cell and volt meter to gather data, and two smaller solar cells to power the motor.
The Single Axis Tracker is controlled by some simple physics. A single geared motor turns the main panel towards the sun. Two small solar panels are attached to a motor, in opposite polarity. When Panel A is producing power, the motor turns clockwise; when Panel B is producing power, the motor turns counterclockwise. When both panels produce equal amounts of power, they cancel each other out, and the motor stops turning.
