Solar Photovoltaic Servo Tracking Controlled System

Renewable energy has known a great interest during the last two decades. Solar energy is viewed as the cleanest renewable source of energy for the future since it is the least polluting and the most inexhaustible of all known energy sources. Subsequently, technologies that enable the use of solar energy focus on solar thermal collectors and on the photovoltaic effect of semiconductors to generate electricity directly from sunlight. In the case of solar energy, it is shown that optimal energy is obtained when the rays of the sun are incident normally on the collecting surface. Therefore, several techniques and experiments have been conducted recently to develop efficient solar tracking systems. Solar panel tracking systems optimize energy output of photovoltaic panels by positioning them to follow the sun’s path throughout the day. The sun’s position in the sky varies both with installation location, the seasons, and the time of day.
