The design of the NexTracker tracking bracket, the selection of accessories and the installation of modules
should be completed by a professional system installer, which can refer to Jinko's mechanical load.
The load described in this manual is the design load. When calculating the maximum test load, 1.5 times of
safety factor should be considered.
If the design load is greater than 1067Pa (test load is 1600Pa), please consult the supplier.

2.3.2 Mounting with clamps

The module clamps should not come into contact with the front glass and must not deform the frame. Be
sure to avoid shadowing effects from the module clamps. The module frame is not to be modified under
any circumstances. When choosing this type of clamp-mounting method, please be sure to use at least
four clamps on each module, two clamps should be attached on each long sides of the module.
Depending on the local wind and snow loads, if excessive pressure load is expected, additional clamps
or support would be required to ensure the module can bear the load. The applied torque value should
be big enough to fix the modules steadily (Please consult with the
clamp or support's supplier for the specific torque value, Such as M8
Screw torque reference value is 16~20N*M). Please find detailed
mounting information in the below illustration, the mounting place
distance is suggested bigger than J and less than K. The installation
diagram of clamp is shown in figure 5.
Note: The Movement of the mounting rail and the clamps center line
are recommended to be within the black arrow area.
As shown in the figure on the right, the minimum length L of the
clamps is 50mm.
