A Kind of Building-integrated Photovoltaic Power Generation System with High Efficiency and Low Cost

介绍了一种与建筑一体化的光伏发电系统,提出固定的二次反射多平面镜聚光系统,可成倍地增大太阳电池的输出功率,大幅度降低系统成本。在金数龙仿真物理实验室仿真软件设计的基础上,经过分析,得出下方与上方反射镜的数据;实验表明,太阳光线能够均匀地聚光在太阳电池上,达到二倍光强的效果。系统功能完善,安装简单而且抗风能力强,有很好的应用前景。

This paper introduces a kind of building-integrated photovoltaic power generation system and puts forwards fixed concentrating system which consists of poly-faceted mirrors of two-stage reflections. The system can multiply the output power of solar cells and decrease cost on large scale. On the base of simulation by means of Jin Shulong physics laboratory software,the data above and below the reflecting mirrors are obtained by analyzing. The experiment indicates that sun ray can focus on solar cells on average with twice the light intensity. The system is of perfect function, simple installation and good wind load. There will be a good prospect of application.
