installing module in offshore areas, protect the connectors or add dust plugs. After removing the dust
plugs, connect the connectors immediately and take other anti-rust measures to prevent rust.
When the modules are installed on the roof, they must be separated from the roof by more than 10cm to
facilitate air circulation and heat dissipation.
2.2.3 Tilt Angle Selection
The tilt angle of the PV module is measured between the surface of the PV module and a horizontal
ground surface (Figure 1). The PV module generates maximum output power when it faces the sun
directly.
For standalone systems with batteries where the PV modules are attached to a permanent structure, the
tilt angle of the PV modules should be selected to optimize the performance based on seasonal load and
sunlight. In general, if the PV output is adequate when
irradiance is low (e.g., winter), then the angle chosen
should be adequate during the rest of the year. For grid-
connected installations where the PV modules are
attached to a permanent structure, PV modules should be
tilted so that the energy production from the PV modules
will be maximized on an annual basis.
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:
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.
