Select a suitable location for installation of the module.
For optimum performance, the module must be facing true south in northern
latitudes and true north in southern latitudes.
For detailed information on optimal module orientation, refer to standard solar
photovoltaic installation guides or a reputable solar installer or systems integrator.
Shading on the module will reduce electricity production.
Do not install the module near equipment or in locations where flammable gases
can be generated or collected.
Observe all instructions and safety precautions included with the mounting system
to be used with the module.
Do not drill holes in the glass surface of the module. Doing so will void the
warranty.
Do not drill additional mounting holes in the module frame. Doing so will void the
warranty.
Modules must be securely attached to the mounting structure using four mounting
points for normal installation. If heavy wind or snow loads are anticipated,
additional mounting points should also be used. Please see the drawing below.
Load calculations are the responsibility of the system designer or installer.
The mounting structure and hardware must be made of durable, anti-corrosion
and UV-resistant material.
4.1 Mounting with bolts
A minimum of four module clamps should be used, two on each long/short frame
side, in the general clamping areas denoted by the wide arrows on the drawing.
Other mounting methods are acceptable as long as the minimum requirements
as described under term 4.2 mounting with clamping hardware are met.
If module clamps are used to secure the module, The torque should refer to
mechanical design standard, we recommend the following torque for bolt:
M6------9 N.m
M8------16~20 N.m

3.1 Selecting the location
3.2 Selecting the proper mounting structure and hardware
4.2 Mounting with clamping hardware
The module must be attached and supported by at least four bolts through the
indicated mounting holes.
Most installations will use the four inner mounting holes on the module frame.
Depending on the local wind and snow loads, additional mounting points may be
required.
Four or Eight pre-drilled mounting holes, located on the aluminum alloy frame, are
provided for ease of installation. They are designed to be used with metric M8
stainless steel screws. We recommend to use a tighten torque of 16~20 N.m
Mounting hole installation
Use four mounting holes
snow load 2400Pa/wind load 2400Pa
Use four mounting holes
snow load 5400Pa/wind load 2400Pa
