技术领域
本发明涉及光伏组件安装技术领域，具体涉及一种光伏防松脱边框组件及太阳能光伏组件系统。
背景技术
随着能源的不断消耗和能源价格的上涨，新能源的开发利用成为当今能源领域研究的主要课题。由于太阳能具有无污染、无地域性限制、取之不竭等优点，研究太阳能发电成为开发新能源的热门方向之一。现阶段中，利用太阳能电池发电是人们使用太阳能的一种主要方式。
传统太阳能晶体硅电池组件的安装方式采用螺丝安装和压块安装：螺丝安装方式为用螺栓穿过组件边框的安装孔和光伏支架安装孔，用下压块锁紧固定，此方法比较工序复杂，不易操作，操作工在锁螺丝的过程中，手中的扳手容易将晶体硅组件背板刮伤，甚至刮破，影响了晶体硅组件的整个生命周期。随着成本的降低，太阳能晶体硅电池组件的铝边框做的越来越薄，此安装方式操作难度越来越大，应用也越来越少；压块安装方式为在组件之间增加一个压块，同时压在两块组件上，螺栓穿过压块对应的螺丝孔将压块、晶体硅组件以及晶体硅组件下方的型材固定，用矩形下压块或常规下压块锁紧固定，方法比螺丝安装方式简单，易操作，但采用压块安装，在动态载荷条件下，一旦螺丝没有锁紧，光伏组件在载荷条件下横向会有位移，压块容易松动，光伏组件最终会滑落，进而引起相邻组件松脱滑落，造成整串光伏组件阵列滑落，发生重大事故，造成人员伤亡和经济的损失。
