Abstract

Solar energy is one of the most commonly used types of renewable energy in areas that experience a lot of sunlight annually. Most solar panels are installed in a stationary position where they receive solar radiations from the sun. But still, there is a lot of solar energy that escapes as the sun rises and sets. Two stepper motors are used for dual axis movements of the panel, as it seeks for points where sunlight energy is highest. One motor tilts the panel through an angle of 45° on the vertical axis and the second motor will rotate the panel through 360° angle at a point on the horizontal axis. The control circuit which is programmed to give a signal to the stepper motors to rotate after a given time so that the solar panel can track the sun, and then give voltage signals to the controller. The messages are compared and the maximum voltage is the point where the panel will be stationed for a particular period of time.
