2.3 Mechanical Installation introduction
Solar PV modules usually can be mounted by using the following methods: bolts and clamps.
﹡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:
1) Visually check the module for any damage. Clean the module if any dirt or residue
remains from shipping.
2) Check if module serial number stickers match.
3) The minimum distance between modules should be more than 10mm for all installation
methods.
(3) The fixation with bolts and/or the fixation with clamps at long side of frames of Jinko
modules are designed to meet a maximum positive (or downward) pressure of 3600Pa
and negative (or upward) pressure of 1600Pa. The fixation with clamps at short side of
frames and/or at the long & short sides of frames of Jinko modules are designed to meet a
positive (or downward) pressure and negative (or upward) pressure of 1600Pa. 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) Where common grounding hardware (nuts, bolts, star washers, spilt-ring lock washers,
flat washers and the like) is used to attach a listed grounding/bonding device, the
attachment must be made in conformance with the grounding device manufacturer's
instructions.
(5) Common hardware items such as nuts, bolts, star washers, lock washers and the like
have not been evaluated for electrical conductivity or for use as grounding devices and
should be used only for maintaining mechanical connections and holding electrical
grounding devices in the proper position for electrical conductivity. Such devices, where
supplied with the module and evaluated through the requirements in UL 1703, may be
used for grounding connections in accordance with the instructions provided with the
module.
(6) The use of third party grounding device is not allowed unless the grounding device is
UL2703 certified with Jinko modules. The installation of that grounding hardware must
follow the grounding manufacture‟s installation manual.
(7) The clearance between the module and the roof deck should be a minimum of 15mm (6
inches).
