A conventional energy resource is limited and causes environmental pollution, so the world is focusing on renewable energy resources, particularly solar energy. Conversion of solar radiation into electricity by a solar module has limited efficiency and also costly. A Solar tracker tracks the Sun more efficiently and maintains a solar module perpendicular to the sun’s rays throughout the day, hence it increases the electricity generation and reduces the cost in terms of number of modules needed. In this research paper, by using light sensors and comparators, a solar tracker is designed. Here the solar tracking systems tracks the Sun using Light Dependent Resistors (LDR) and then actuate the DC motor to position the solar module where it can receive the maximum sunlight. Instead of using complex controlling system and programming like other trackers, a simple tracker is designed which is cost effective and increases electricity generation.
