摘要
太阳能电池板的效率偏低导致光伏发电系统成本过高,是困扰其长足发展的主要原因。阐述了光伏发电自动跟踪系统的基本原理和研制的关键技术并以PIC16F877A为核心控制单元,设计了一种自动太阳跟踪器,能自动跟踪太阳的高度角与方位角,使太阳光线始终垂直入射在光伏阵列的表面以获取最大发电效率。详细介绍了系统软硬件设计方案并研制出相应可靠稳定运行的样机。
The main idea of restricting development is that solar panels lead to low efficiency photovoltaic power generation system too costly. The basic principle and key technology based on PIC16F877A of it is proposed. An automatic sun trackers following with the azimuth angle and the solar altitude of the sun based on PIC16F877A is designed in this paper,which makes vertical incidence sunrs ray on the surface of photovoltaic （PV） arrays and maximizes generating efficiency. The hardware and software schemes of system are introduced in detail,and finally automatic sun trackers running reliably are developed.
