摘要

为提高太阳能电池板的光电转换效率，研究了太阳追踪技术，设计一种基于STM32控制器的太阳自动追踪系统。针对太阳方位角与高度角运动范围的差异，设计六光敏区的传感器模块作为光电检测器，保证宽范围内太阳位置的检测。提出变比例因子的比例控制算法，用于快速跟踪太阳位置，将粗调模式和细调模式结合，进行大角度太阳位置跟踪。将光电检测追踪算法和视日运动轨迹追踪算法结合，实现晴朗天气条件下和多云天气条件下对太阳空间位置的实时追踪，控制太阳能电池板保持在最优受光位置，实现提高输出功率的目标。实验结果表明，设计的系统可以实现精确的太阳追踪，误差小于1°。系统灵敏度高，追踪性能稳定，提高了太阳能电池板的光电转换效率。

Abstract

To improve photoelectric conversion efficiency of solar panel

a research is conducted on the solar tracking technology and a solar auto-tracking system based on STM32 controller is designed. Considering the difference in solar movement range in the azimuth angle and altitude angle

design a sensor module in the six photosensitive areas as the photoelectric detector to ensure solar position detection in a wide range; put forward the ratio control algorithm for variable scale factors to fast detect the solar position

and combine coarse tuning mode with fine tuning mode to achieve large-angle solar position tracking; combine the photoelectric detection tracking algorithm with the solar movement tracking algorithm to achieve real-time tracking of solar position in fine weather and cloudy weather

control the solar panel in the optimal lighting position

and improve the output power. It indicates that the system designed can achieve accurate solar tracking

with an error lower than 1°. The system

with high sensitivity and stable tracking performance

helps improve the photoelectric conversion efficiency of solar panel.
