摘　　要：基于历史气象数据建立辐射传输模型,对比屋顶光伏板平铺式安装和倾斜式安装的发电效益差异,评估多种工业厂房光伏屋顶构造形态的发电效益。结果表明:相对于倾斜式安装,同等面积的平顶厂房平铺式安装光伏板每年可以提高70.9%的发电量,单位面积年平均发电量仅减少4.49%;相对于倾斜式光伏系统,平铺式安装于拱顶、双坡、多跨、多脊式厂房屋顶的光伏系统的年度发电量均有较大提升;多脊式光伏屋顶年发电总量增大102.2%。Based on historical meteorological data,a radiation transmission model was established to compare power generation efficiency between tiled and inclined roof photovoltaic installations,and evaluate power generation efficiency of photovoltaic roof structural forms of various industrial plants.The results show that for flat-roofed industrial plants with the same area,the tiled installation of photovoltaic panels can increase the power generation by 70.9%annually compared with the inclined installation,while the annual mean photovoltaic power generation of per square meter only decreases by 4.49%.Compared with inclined photovoltaic systems,annual power generation of tiled photovoltaic systems installed on vault,double slope,multi-span,and multi-ridge plant roofs of industrial plants increases greatly.The annual power generation of multi-ridged photovoltaic roof increases by 102.2%.
