Abstract:
Energy crisis is the most important issue in today’s world. Conventional energy resources are not only limited but also the prime culprit for environmental pollution. Renewable energy resources are getting priorities in the whole world to lessen the dependency on conventional resources. Solar energy is rapidly gaining the focus as in important means of expanding renewable energy uses. The energy extracted from solar photovoltaic (PV) or solar thermal depends on solar insulation. For the extraction of maximum energy from the sun, simple tracking solar system using servo motors and light dependent sensors has been developed. A microcontroller is based designed based design technology of an automatic solar tracker is presented in this work. Sun trackers move the solar collector to follow the sun trajectories and keep the orientation of the solar collector at an optimal tilt angle.
In this work, two axis solar tracking has been implemented through microcontroller. This method is increasing power collection efficiency by developing a device that tracks the sun to keep the panel at a right angle to its rays.
