Design of ARM-Based Solar Tracking System

This paper presents a solar tracking system based on ARM, which mainly adopts the solar trajectory tracking mode, supplemented by the photoelectric sensor tracking mode according to the weather condition, and control the motor rotation to achieve all-time accurate solar tracking. The experimental results show that, the system performance is reliable, and all-weather tracking accuracy is maintained within 0.15 degrees. Therefore, the system can be widely used in solar photovoltaic power generation and lighting devices with solar energy utilization ratio improving greatly.
