光伏建筑一体化项目不同安装方式的案例分析

作为分布式光伏发电的重要应用方式，光伏建筑一体化（BIPV）受到越来越多的重视，但是实现光伏组件和建筑的美观、可靠和低成本的结合仍是一个具有挑战性的难题。在一个获得财政部和住建部“光伏建筑一体化”资金资助的项目中实验了不同的BIPV组件安装方式，包括隐框光伏幕墙、彩钢瓦屋顶夹具安装、彩钢瓦屋顶黏接安装方式，其中采用粘贴的方式在彩钢瓦屋顶安装双玻组件为我们独创的施工方法，具有快捷、质轻、低成本和高可靠性等特点，而且不需要在彩钢瓦上打孔，避免漏水隐患。发电量结果表明，在干燥、多粉尘的季节，在立面安装的光伏组件的单位装机容量的发电量也可能大大高于安装于斜面屋顶的组件，说明光伏玻璃幕墙有着很大的发展前途。

Case Analysis on Various Installation Methods of Building Integrated Photovoltaic

Building integrated photovoltaic （BIPV） as an important application of distributed photo-voltaic power generation, has being focused more and more, but it still faces challenges of achieving the aesthetics with PV modules, and combining of reliability and low cost. Various BIPV application methods are studied, and experimented in the project funded by Ministry of Finance and Ministry of Housing and Urban-Rural Development, including curtain wall hidden frame, color steel tile roof with clamps, and color steel tile roof bonding. The color steel tile roof bonding is our original one, characterized by fast installing, light weight, low cost and high reliability. More important, this method does not need holing the color steel tile to avoid leakage risk. Power generation results show, during the dry and dusty seasons, the power gen-eration of modules in facades may higher than slope-roof modules’.
