This document describes the development of an automatic single-axis solar tracking system using a servo motor mechanism. The system includes light dependent resistors (LDRs) to sense sunlight intensity, a microcontroller to send signals to the servo motor, and a mechanical structure to support the photovoltaic panel. The controller coding and servo mechanism were first simulated using PROTEUS 7 software. Then a prototype was developed including the mechanical design, active control components like the LDRs, microcontroller and servo motor, and a power system. Testing showed the tracking system improved average efficiency by 7.67% compared to a fixed panel.
