附加式屋顶光伏阵列是既有建筑与光伏构件最有效的结合方式之一。屋顶光伏阵列的不同排列不仅会影响系统输出电量，还影响建筑能耗。既有建筑屋顶面积有限，光伏阵列倾斜角度的增大会使阵列最小间距增大、阵列排数减少，导致光伏板总安装面积以及建筑顶层房间能耗的变化。以邯郸地区东西70 m、南北20 m 的既有屋顶为例，通过 PVSYST 软件比较了不同倾斜角度下屋顶光伏阵列的发电量，并计算了阵列的投资回收期。结果表明：光伏板倾斜角度为30°~35°时发电量最大，投资回收期最短，为8.61年。采用 DesignBuilder 软件对顶层房间进行了能耗模拟，表明应用光伏阵列的顶层房间年采暖制冷总能耗比普通屋顶房间减少1.8 kW·h/m2。

Additional roof photovoltaic array is one of the most effective ways to combine photovoltaic component with existing buildings. Different arrangement of rooftop photovoltaic arrays will not only affect the system output power, but also affect the building energy consumption. The existing building roof area is limited. The increase of photovoltaic panel angle leads to increasing of minimum spacing between arrays, and reduction of photovoltaic array rows, which can result in changes in the total installed PV panel area and energy consumption of the top floor room. Taking the existing building roof in Handan as an example, which is 70 meters from east to west and 20 meters from north to south, compare the generating capacity of rooftop photovoltaic array of different inclination angles through the PVSYST software, the investment recovery period of photovoltaic array. The calculation results show that the maximum generating capacity comes when the photovoltaic panel tilt angle is 30 degrees~35 degrees, at the same time, the investment recovery period is 8.61 years which is the shortest. The energy simulation result of the top floor room which comes by DesignBuilder software shows that the total energy consumption of heating and refrigeration for the top room with photovoltaic array reduced 1.8 kW·h/m2 compared with the top room with ordinary roof.
