太阳能电池板已广泛应用于光伏发电系统，但固定不动的光伏发电装置未能实现对太阳光的实时追踪，转换效率并不高。为高效利用太阳能，采用太阳能电池板自动追光系统。文中着重分析了电池板的双轴控制及自动追光原理，并设计了太阳能电池板自动向光系统。运行结果表明该系统实现了太阳光时刻垂直照射电池板，达到对太阳光的实时跟踪，可望在太阳能光电工程中获得应用。
Solar panels have been widely used in photovoltaic power generation system, but the photovoltaic device is stationary failed to achieve real-time tracking and high sunlight conversion efficiency. For the efficient use of solar energy, a solar panel sun-tracking system has been applied. This paper analyzes the biaxial control panels and automatic recovery of light principle, and designs the solar panel sun-tracking system. The result shows that this system achieves perpendicular irradiation of sunlight to the solar panels all the time, and the real-time tracking of sunlight. It is expected to find application in solar photovoltaic project.
