摘　　要：间隙排列PV结构兼具遮阳、采光、发电等性能,宜用作建筑顶部采光设施.文中针对广州地区的气候条件,对4种不同参数的PV结构进行对比研究,综合考虑采光性能与发电能力,选出了PV面板安装的最优方案,即PV面板与水平面之间呈60°倾角,以此在保证较高采光能力的同时提供良好的发电能力;通过在设计案例中的应用对间隙排列PV结构的采光及发电性能进行了分析,结果表明:该间隙型PV结构具有良好的遮阳效果,其下方10 m处地面的平均采光系数为4.9%,年度累计发电能力为61.8 k W·h/m2.The structure of PV panels arranged with gaps is appropriate for the top daylighting of buildings thanks toits performances of shading, day lighting and power generation. In this paper, by taking into consideration the climatecondition in Guangzhou area, 4 types of PV structures with various parameters were investigated in a comparativeway, and an optimized layout scheme of PV panels was selected by comprehensively considering both daylightingperformance and power generation capability, namely, constructing a tilt angle of 60° between the PV paneland the horizontal plane to ensure good daylighting performance and provide strong power generation capability.Moreover, the optimized scheme was analyzed in terms of daylighting performance and power generation capabilitythrough a building design case. The results show that the presented PV structure possesses good shading performance, and that it helps achieve an average daylighting factor of 4. 9% on the ground being 10m lower the PVstructure and an annual power generation capability of 61.8kW-h/m^2.
