refer to the mentioned module type in this manual) and negative (or upward) pressure of 1600Pa.
This design load was then tested with a safety factor of 1.5 times. So Jinko modules are tested under
a maximum downward pressure of 5400Pa and upward pressure of 2400Pa. When mounting
modules in snow-prone or high-wind environments, special care should be taken to mount the
modules in a manner that provides sufficient design strength while meeting local code requirements.
2.3.1 Mounting with Bolts
For mounting with bolts, the following modules in tables 1 are applicable.
The frame of each module has 8 mounting holes (Length* Width: 14mm*9mm) used to secure the
modules to support structure. Always use all the eight mounting holes to secure the modules. The module
frame must be attached to a mounting rail using M8 corrosion-proof bolts together with spring washers
and flat washers in eight symmetrical locations on the PV module. The applied torque value should be
big enough to fix the modules steadily. The reference value for M8 bolt is 16~20N*m. As to special support
system or special installation requirement, please reconfirm with the support’s supplier for the torque
value. Please find detailed mounting information in the below illustration as Figure 2&3&4.
