Abstract
Solar energy is one of nature's most abundant sources of electricity and one of the most efficient kinds of renewable energy. The Solar Tracking System keeps track of the sun's movement through the sky. It tries to keep the solar panel perpendicular to the sun's beams all day long, ensuring that the panel receives the maximum amount of sunlight. The Solar Tracking System comprises two LDRs, a solar panel, a stepper motor, and an ATMEGA8 microprocessor. In this system, a microcontroller 8051-based circuit is employed with a small number of components, and stepper motors are used to follow the sun accurately. A solar mobile charger with a solar tracking system has been designed and developed in this study. The quantity of energy generated by a solar cell is stored in a battery. The photovoltaic cell will be positioned according to the intensity of sunshine. Because the sun will be higher on the west side in the morning, the solar tracker will be on the west side. Similarly, at midday, the intensity of sunlight is the same in both directions. Therefore the photovoltaic cell does not move and remains stationary. The motor can control the solar cell's movement. And, depending on the intensity of light falling on the LDRs employed in the solar cell, it will be positioned west or east. As a result, by implementing this scheme, we want to utilize solar energy better to provide a consistent supply to loads and alleviate the energy crisis to a large extent. Consequently, the electricity bill will be lower, and the cost of electricity generation per unit will be lower.
