Project Description
Traditional solar trackers rely on light-dependent resistors (LDRs), which can be unreliable under cloudy or dusty conditions. This project introduces a GPS-based solar tracking system that calculates the sun’s position algorithmically.
By using geographic location and time data, the system adjusts the solar panel orientation throughout the day for optimal energy capture.
The Challenge
Accurately calculating sun position and synchronizing motor movement without real-time light sensing.
The Process
GPS data was processed to determine solar angles, and motor control logic was developed to align panels smoothly.
The Solution
A robust solar tracking system independent of ambient light conditions.
The Results
Improved energy harvesting efficiency and consistent performance in varying weather conditions.
