什么是建筑光电一体化系统?

答案

参考答案:“太阳能光伏系统”是包含太阳能电池阵列、逆变器和相关控制部件,并具有一个公共连接点的电力系统。安装在地面的大型的独立式PV系统,一方面消耗土地资源,另一方面需将电力输送出去,会带来输配电的损耗。而分布式PV太阳能光伏系统,应用于建筑工程,克服了上述缺点,但由于一体化程度低,安装在设计较好的建筑物上,令人难以接受,而安装在设计较差的建筑物上,感觉建筑档次更低,不利于发展。所谓“建筑光电一体化”,应该是PV与建筑的有机结合,不仅建筑本身成为PV的结构载体,而且PV系统替代了传统的建材,它作为建材元素(如屋顶瓦片、防水层、保温层、外墙围护结构、遮阳板和屋檐等)成为建筑的一部分。

其优点不仅是节约土地资源和就地发电就地用电,节省输电成本,而且可以取代或节约建筑外饰材料,减少了PV系统的净成本,而且可以取代或节约建筑外饰材料,减少了PV系统的净成本,缓解白天用电高峰的供电压力,同时赋予建筑美新的技术内涵,形成新的视觉效果,体现了节能与建筑美的完美结合。

目前,实现建筑光电一体化的建筑,不少将所获得的电能首先应用于建筑照明。实现建筑光电一体化需在获取最大的太阳能的同时,综合考虑解决“实现一体化”有可能遇到的建筑的采光与遮阳、防水与绝缘、供热与保温、光电板与镜面反射,大气污染与昆虫入侵,线路敷设与系统散热,维护方便与结构安全等等许多复杂的技术问题,实现的过程必定是建筑艺术与技术创新的过程。
