Note:
1) All installation methods herein are only for reference, and Jinko solar will not provide related
mounting components, the system installer or trained professional personnel must be
responsible for the PV system's design, installation, and mechanical load calculation and
security of the system.
2) Before installation, the following items should be addressed:
a) Visually check the module for any damage. Clean the module if any dirt or residue
remains from shipping.
b) Check if module serial number stickers match.
3) Jinko modules are designed to meet a maximum positive (or downward) pressure of
3600Pa(Only 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.
4) When installing the Dual glass modules at a certain angle, please installed the modules in
front of the sun. But the back which the surface mounting the junction box is not allowed to
exposed to the sun.
2.3.2.3 Fixation with clamps at long sides of frames (Long sides with C, short sides
without C)
When installing modules using clamps on the long side of the frame, the mounting place distance
of middle of clamp is suggested bigger than J and less than K. the length of clamp is 40mm. The
applicable product types and installation locations are shown in figure 4 and table 8, the following
types have the same section design.
