固定式光伏发电系统潜在效能分析

Potential Effectiveness of Fixed Photovoltaic Generation System

在家用固定式光伏发电系统中,为了提高发电量,近年来关于新的材料以及结构的安装的研究越来越多。家用固定式光伏发电系统由于安装的光伏板的数量比较少,一般直接安装于屋顶或墙壁,以减少所占用空间,缺点在于无法移动,所以不仅受限于光照的角度而且受限于光伏系统的换热,导致无法达到理想的功率与效率。通过理论计算分析来估算可提升的功率的大小,以及在优化散热方面的可行性的分析,得出背板散热存在最大增幅、极限的特点。

In order to increase the amount of electricity generated for stable Photovoltaic System,there are more and more researches on materials and installation methods in recent years. Because the number of photovoltaic panels is relatively small and people want to save space,most people install the system directly on a roof or wall,the installation design result in inability to move. So the system is not only limited by the angle of light,but also limited by the heat transfer,then the desired power and efficiency are difficult to obtain. It is concluded that the heat dissipation of backplane has the largest increase and the limit,through the theoretical calculation and analysis for estimating the power,and the feasibility analysis of optimizing the heat dissipation.
