薄膜硅点支承光伏幕墙和光伏采光顶实际案例分析

摘要

Photovoltaic integrated architecture is one of the most important distributed photovoltaic power generation application, which obtains wide attention. The article introduces thin-film silicon photovoltaic module adopted to splicing method to meet different size of curtain wall through an existing renovation project. Through structure optimization of photovoltaic component, it ensures safety and functionality of photovoltaic component besides power loss is within the acceptable range caused by supporting hole to photovoltaic component. Otherwise, daylight roof applies large size splicing photovoltaic component with different color to realize different visual effect. The project provides reference to different split size photovoltaic curtain wall, especially its point supported photovoltaic curtain wall, meanwhile it could change photovoltaic component color to realize different visual effect.%光伏建筑一体化作为分布式光伏发电的一种重要应用形式，广受关注。通过一个既有工程改造项目，介绍了硅基薄膜光伏组件可以采用拼接方式满足幕墙不同分格尺寸的要求，并通过光伏构件的结构优化，确保了构件的安全性、功能性以及支承孔对构件带来的功率损失在可接受范围内。另外，采光顶采用了不同颜色的大尺寸拼接光伏构件，实现了不同的视觉效果。此项目可对于不同分格尺寸的光伏幕墙尤其点支承光伏幕墙提供借鉴，同时可以通过改变光伏构件的颜色来实现建筑的不同视觉效果。
