摘要
提出了一种新型的嵌入模块式光伏组件体系,该新型光伏组件体系能够取代传统的屋顶围护构件,实现光伏技术与建筑的一体化集成。通过力学性能试验验证了该新型光伏组件体系在2 500 Pa外荷载作用下的挠度值满足建材的变形控制要求,应力值远小于材料的极限强度,可取代传统的屋顶围护构件。通过发电效率试验测得该新型光伏组件体系的最大发电效率衰减为4.65%,低于GB/T 9535—1998《地面用晶体硅光伏组件设计鉴定和定型》规范中规定的5%。通过静态水密性试验验证了该新型光伏组件体系的水密性符合GB/T 15227—2007《建筑幕墙气密、水密、抗风压性能检测方法》规范的要求。
A new PV system called the embedded modular PV system was proposed.This new PV system can replace the traditional envelope components of building roofs and is a kind of building Integrated PV.The mechanical behavior,power generation and watertightness of the proposed PV system were investigated by tests.It is verified that the stiffness and the strength of the system under a given load of 2 500 Pa meet the requirement for envelope components of building roofs.The maximum ratio of power-generation reduction of the system is 4.65% which is lower than the criterion of 5% given by the national standard（GB/T9535-1998） ＇Crystalline silicon terrestrial photovoltaic（PV） module-design qualification and type approval＇.It is also shown that the watertightness of the system meets the requirement of the corresponding national standard（GB/T 15227-2007） ＇Test methods for airtightness,watertightness and wind resistance of glass walls for constructions＇.
