Abstract - A Dual Axis Solar Tracking System is an advanced solar power generation system that increases the efficiency of solar panels by continuously aligning them with the sun’s position throughout the day. Unlike fixed solar panels, which remain stationary, this system tracks the sun in two directions: horizontal (azimuth) and vertical (elevation). By maintaining the panel perpendicular to the sun’s rays, maximum solar radiation is captured, thereby improving overall energy output.
The system typically uses Light Dependent Resistors (LDRs) or other light sensors to detect the intensity of sunlight from different directions. A microcontroller such as Arduino Uno processes the sensor data and controls two DC or servo motors to adjust the panel’s position along both axes. The horizontal axis tracks the sun from east to west, while the vertical axis adjusts according to seasonal changes and the sun’s height in the sky.
The dual-axis tracking mechanism significantly increases energy generation compared to a fixed solar panel system, with efficiency improvements of up to 30–40%. This makes it suitable for applications in solar power plants, street lighting systems, and remote area electrification. Although the system has slightly higher installation and maintenance costs due to moving components, the increased power output compensates for these costs over time.
In conclusion, the Dual Axis Solar Tracking System enhances the performance of photovoltaic systems by maximizing solar energy harvesting, contributing to sustainable and renewable energy development.
