2、耗低、成本低、抗干扰能力强等特点。 单轴太阳能自动跟踪系统通过单片机控制系统自动跟踪太阳方位角，高度角可手动进行调整,使太阳能电池保持较大的发电功率。 通过对单轴自动跟踪系统与双轴自动跟踪系统发电效率的比较,理论证明它的可行性。本设计取消了用于检测太阳能电池板法线与太阳光线间夹角的传感器，而直接利用太阳能电池板发电量作为角度调节依据实现控制。 我国牧区大量使用的是无跟踪的光伏系统，太阳能发电效率较低。本文所述的单轴跟踪系统，结构简单，性价比高，特别适宜在这些地区使用。 关键词：光伏系统；太阳角自动跟踪；单轴跟踪系统 Abstract With the resources being used

3、continuously, the energy structure based on Conventional energy resources will not more and more adapt to requirement of sustainable development. So accelerating the exploitation and utilization of renewable resources that solar energy is principle part has been our common ideas. Using the clean sol

4、ar light energy, the technology of photovoltaic generating electricity is very promising. The thesis presents a new optimal design method. This thesis mainly describes a method of single axis solar energy automatic tracing system. Every part of this automatic system and its function are analyzed in

5、detail. A set of automatic tracing device is designed with Microcontroller AT89C52. This system has four characteristics, such as smaller cubage, lower power, lower cost, more robust despite strong interfere. Moreover, some programs are designed to debug the designed system, to test its reliability

6、and the resultsof test are given. Single axis solar energy automatic tracing system follows the orientation angle with Microcontroller system.
