为了提高太阳能电池的能量转化效率，依据太阳运行规律和季节的变化特点，设计了一种光电跟踪和太阳轨道跟踪相结合的实时太阳跟踪系统。采用平衡式阵列光电传感与时钟计算组合方法，分析太阳运动轨迹与方位控制对阳光跟踪与能量转换效率的影响，基于四元阵光电传感对太阳运动轨迹与方向变化的阳光跟踪光电控制系统原理，通过光照强弱与时钟计算太阳历史位置进行快速跟踪。实验结果表明，该系统能实现太阳位置的二维实时跟踪和太阳能电池姿态控制，在光强大范围变化条件下也可精确地跟踪，大大提高了太阳光的利用率。

Based on the sun rules and the seasonal changes,a sunlight real-time tracking system that combines photoelectric tracking and sun orbital tracking is designed.It adopts the method that combines balanced array photocell sensor with clock calculation to analyze how the trajectory of the sun and the battery azimuth control affects the efficiency of sun tracking and energy conversion.It discusses the solar photoelectric tracking control system theory of how the four-element array changes with the trajectory of the sun.The sunshine is quickly tracked through illumination changes and historical trajectory.The experimental result shows that it can achieve the two-dimension real-time tracking and battery management of the sun posi-tion and make accurate tracking on condition that the light intensity changes within a wide range,which greatly improves the utilization rate of the sunlight.
