大背面承受的静载荷为 2400Pa（相当于风压），正面承受的最大静压力为 5400Pa（相当于
风压和雪压）；
External mounting hole: The internal test mounting hole is fixed to enhance the load
resistance of modules. Suitable for high load conditions: the maximum static load on the back of
the module is 2400Pa (equivalent to wind pressure), and the maximum static pressure on the
front is 5400Pa (equivalent to wind pressure and snow pressure);
 压块安装：螺栓建议采用 M8 规格（长度根据压块设计高度定）并配备相应的垫片、弹簧垫
片和螺母；采用扭力扳手拧紧，扭力大小范围为：18N.m 到 24N.m 之间。
Installation of pressing block: M8 specification is recommended for bolts (length is
determined according to the design height of pressing block) and corresponding gaskets, spring
gaskets and nuts are provided; Use a torque wrench to tighten the screw. The torque range is
from 18N.m to 24N.m.
 安装孔安装：螺栓建议采用 M8 规格（长度根据横梁设计定）并配备相应的垫片、弹簧垫片
和螺母；采用扭力扳手拧紧，扭力大小范围为：14N.m 到 20N.m 之间。

installation of mounting hole: it is recommended to adopt M8 specification (the length is
determined according to the beam design) and be equipped with corresponding gaskets,
spring gaskets and nuts; tighten with torque wrench, and the torque range is between 14N.
M and 20n. M.
 支架结构必须由耐用、防腐蚀、抗紫外线的材料制成。
The support structure must be made of durable, corrosion-resistant and uv resistant
materials.
7.3 地面安装
Floor covering installers
选择合适的光伏系统安装高度，防止冬天下雪时组件的下部长时间被积雪覆盖。此外，还要确
保组件的最低部分足够高，以防被植物或树遮挡或被风吹来的沙石损坏。
Choose the appropriate pv system installation height to prevent the module from being
covered by snow for a long time when it snows in winter. Also, make sure the lowest part of the
module is high enough to prevent it from being obscured by plants or trees or being damaged by
wind-blown sand.
