面向太阳能组件的新型日晷式太阳自动跟踪系统

A New Sundial Sun Tracking System for Solar Components

基于HT66F70A单片机,采取四象限测光原理和传感器定位方式,设计了一套新型日晷式太阳定位跟踪系统。该系统优化了光伏太阳能组件的工作过程,运用HT66F70A单片机实现自动跟踪太阳位置,尽可能使太阳光垂直入射到光伏板上,以获得最大光伏发电利用率,从而提高光电转化率并降低光伏板投入成本。同时,结合风速测量功能,使系统具备抗环境干扰功能,提高了太阳能光电转化利用率,具有广泛的应用前景。

Based on the Single Chip HT66F70A, using a Four Quadrant photometric principle, we designed a novel sundial mode solar positioning tracking system. This system could optimize the working process of PV Module. Through the Single Chip HT66F70A, it could automatically tracking the position of solar, with vertical incidence of solar light, optimizing the photon-to-current conversion efficiency, reduce power generation cost. At the same time, combined wind measurement function, the system was insensitive to environmental disturbance. This system had good prospects for application.
