Installation methods
•
Modules can be installed on the frame using mounting holes, clamps* or an
insertion system. Modules must be installed according to the following examples. Not
mounting the modules according to these instructions may void the warranty.

•
Module can be installed in both landscape and portrait modes.
•
The modules must be properly secured to their support so that they can withstand
live load conditions, including wind uplift, to the pressure they have been certified for.
It is the installer's responsibility to ensure that the clamps used to secure the modules
are strong enough.
* The minimum recommended length for each clamp is 50 mm.
General Installation
•
Before installing modules check for any optical deviations. Any optical deviations
noticed after system installed may void warranty. Any potential costs for labor, material
or other cost such as documentation, safety or performing the (de/ re-) installation will
not be covered.
•
The module mounting structure must be made of durable, corrosion-resistant and
UV-resistant material. Always use a tested and certified mounting structure approved
for your system design.
•
In regions with heavy snowfall in winter, select the height of the mounting system
so that the lowest edge of the module is not covered by snow for any length of time. In
addition, ensure that the lowest portion of the module is placed high enough so that it
is not shaded by plants, trees or damaged by ground soil moved by or through the air.
•
For ground mounting systems, the minimum distance Suntech recommend from
the ground to the bottom of the module is at least 24 inches (60cm).
•
Modules must be securely attached to the mounting structure. For Clamping
System installation methods, the recommended maximum compression for each clamp
is 2900 PSI (20 Mpa) in order to avoid potential damages to module frames. Follow the
instruction of the clamping system supplier.
•
Provide adequate ventilation under the modules in conformity to your local
regulations. A minimum distance of 10 cm between the roof plane and the frame of the
module is generally recommended.
•
Always observe the instructions and safety precautions included with the module
support frames.

•
This installation manual is applicable for all pv system of 500 m or more away from
the coastline. If you need to install your system less than 500m from the coast line
please refer to Near-coast installation manual (www.suntech-power.com) or contact
Suntech's Customer Support department or our regional representatives.
•
Do not use modules near equipment or in locations where flammable gases may
be generated or collected.
Selecting the location
•
Select a suitable location for installing the modules.
•
The modules should face south in northern latitudes and north in southern
latitudes.
•
For detailed information on the best installation angle, refer to standard solar
photovoltaic installation guides or consult a reputable solar installer or systems
integrator.
•
Modules should not be shaded at any time. If a module is shaded or even partially
shaded, it will fail to perform at ideal conditions and result in lower power output. A
permanent and/or regular shade on the module voids the warranty.
Mechanical Installation
•
Before installing modules on a roof, always ensure the roof construction is suitable.
In addition, any roof penetration required to mount the module must be properly
sealed to prevent leaks.
•
Dust building up on the surface of the module can impair with the module
performance. The modules shall be installed with a tilt angle no less than 10 degrees,
making it easier for dust to be removed by rain. A flat angle requires more frequent
cleaning.
•
Observe and take into account the linear thermal expansion of the module frames
(the recommended minimum distance between two modules is 2 cm).
•
Always keep the front and backsheet of the module free from foreign objects,
plants and vegetation, structural elements, which could come into contact with the
module, especially when the module is under mechanical load.
•
When installing a module on a pole, select a pole and module mounting structure
that will withstand the anticipated wind load and snow load for the area.
•
Ensure modules are not subjected to wind or snow loads exceeding the maximum
permissible loads, and are not subject to excessive forces due to the thermal expansion
of the support structures. Never allow modules overlap or exceeds the rooftop: Refer to
the following installation methods for more detailed information.
