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 10m 处地面的平均采光系数为 4． 9%，年度累计发电能力为 61． 8kW·h/m 2 ．

The structure of PV panels arranged with gaps is appropriate for the top daylighting of buildings thanks to its performances of shading,daylighting and power generation.In this paper,by taking into consideration the cli- mate condition in Guangzhou area,4 types of PV structures with various parameters were investigated in a compara- tive way,and an optimized layout scheme of PV panels was selected by comprehensively considering both dayligh- ting performance and power generation capability,namely,constructing a tilt angle of 60° between the PV panel and 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 capability through a building design case.The results show that the presented PV structure possesses good shading perfor- mance,and that it helps achieve an average daylighting factor of 4.9% on the ground being 10m lower the PV structure and an annual power generation capability of 61.8kW·h/m 2 .
