Description

一种柔性光伏组件的安装方法及安装系统 技术领域
本申请涉及但不限于太阳能光伏组件产品的安装领域，尤其涉及一种柔性光伏组件的安装方法及安装系统。
背景技术
随着新能源利用技术的不断发展，分布式太阳能发电为人们提供了更加便捷的能源供应。分布式太阳能发电需要一定的空间作为场地载体。目前除了光伏地面电站外，分布式光伏电站主要安装在建筑物的屋顶、立面等空间。光伏电站的自身重量对所安装的建筑产生了一定的重量荷载。光伏电站的自身重量主要来自光伏组件(玻璃、钢板等)和安装系统(金属支架、衬板等)。
现有光伏组件按材料分类主要有晶硅、非晶硅、柔性等类型，由于材料特点及封装工艺的不同，晶硅材料和大部分非晶硅材料制成的光伏组件产品采用玻璃封装、不能弯曲，因此该类光伏组件质量笨重、惧怕振动和应力突变。为了满足此类组件的封装、安装条件，往往需要大量的玻璃封装、金属支架、配重进行安装，从而造成重量载荷急剧上升，所增加载荷一般都会超过20公斤。因此，系统自身重量影响了晶硅非晶硅玻璃基组件的分布式应用范围。
柔性光伏组件是一种新型的太阳能光伏组件，采用了铜铟镓硒(CIGS)发电技术，特点是可弯曲、可粘贴，采用乙烯-四氟乙烯共聚物(ETFE)等非金属进行封装后可直接贴装在立面、弧形棚面等位置，质量仅为晶硅/非晶硅玻璃基组件的三分之一左右。如采用直接贴装，则要求粘贴表面面积满足柔性组件产品的最小面积模数，同时要具备一定的平整度。因此，建筑表面贴装条件影响了柔性组件分布式发电的应用范围。
综上，来自于光伏系统自身重量、建筑表面条件是太阳能分布式发电应用的制约因素。

综上，本申请实施例中，设计了轻质钢索张拉安装，利用多根钢索的预拉力形成张力，通过与柔性光伏组件进行多点非刚性连接，实现光伏系统的稳定可靠支撑。此外，可选地，采用柔性CIGS铜铟镓硒材料的光伏组件，可以实现芯片抗应力能力强(飞石、风载荷)、组件可弯曲、产品自重小。因此，采用本申请提供的柔性光伏组件的张拉安装系统，可以进一步降低光伏发电系统的自重，避免安装表面的对柔性光伏组件安装的限制，实现柔性光伏组件的快速拆装，安装工艺简单，系统自重小，提升了应用灵活度。
