Table 3: Mechanical dimensions for bolt fitting method (NEX)
Note：The installation method of bolt fitting (NEX) is based on the experimental results in Jinko.
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.
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). 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.
