Do not install the PV module in a location where it would be immersed in water or continually
exposed to water from a sprinkler or fountain etc.
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
