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.
According to IEC 61215 for a maximum positive design loading of below 1067Pa, and negative design
loading 1067Pa, with 1.5 times safety factor.
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.
The min length of clamps is 50mm.
