Abstract

The phrase “the sun is the source of all energy” highlights the vital role of solar energy in sustaining life and powering our planet.. Solar power is rapidly emerging as a option for renewable energy resources. As an abundant energy source, sunlight can be effectively harnessed using solar photovoltaic cells and the photovoltaic effect to transform solar energy into electricity. A solar tracking system enhances the energy output of solar setups by following the sun’s movement with panels throughout the day, thus optimizing the angle at which they receive sunlight. In comparison to fixed solar panels, a solar tracking system utilizing linear actuators or gear motors can boost the efficiency of solar panels by 25% to 40%. The efficiency of any solar-based application improves when the panels are consistently adjusted to the best angle as the sun moves across the sky. A dual-axis tracker enables solar panels to rotate along both the north-south and east- west axes. The following material describes the layout and implementation of a dual-axis” solar panel powered by the Arduino microcontroller.
