Mechanical Installation
Selecting the location
Select a suitable location for installing the modules.
The modules should be facing south in northern latitudes and north in southern latitudes.
For detailed information on the best elevation tilt angle for the installation, refer to standard solar photovoltaic installation guides or a reputable solar installer or systems
integrator.
The module should not be shaded at any time of the day.
Do not use module near equipment or in locations where flammable gases can be generated or collected.
E
Selecting the proper support frame
Always observe the instructions and safety precautions included with the support frames to be used with the modules.
Do not attempt to drill holes in the glass surface of the modules. To do so will void the warranty.
Do not drill additional mounting holes in the frame of the modules. Doing so will void the warranty.
Modules must be securely attached to the mounting structure using four mounting points for normal installation. If additional wind or snowloads are anticipated for this
installation, additional mounting points are also used. The details please see the below drawing. Load calculations are left to the system designers or installers.

Mounting holes for normal installation
For high wind and snow-loads, these mounting
holes must also be used
Mechanical Installation
The support module mounting structure must be made of durable, corrosion-resistant and UV-resistant material.
Ground mount
Select the height of the mounting system to prevent the lowest edge of the module from being covered by snow for a long time in winter in areas that experience heavy
snowfalls. In addition, assure the lowest portion of the module is placed high enough so that it is not shaded by plants or trees or damaged by sand and stone driven by wind.
Roof mount
When installing a module on a roof or building, ensure that it is securely fastened and cannot fall as a result of wind or snow loads.
Provide adequate ventilation under a module for cooling (10cm minimum air space between module and mounting surface).
When installing module on a roof, ensure that the roof construction is suitable. In addition, any roof penetration required to mount the module must be properly sealed to
prevent leaks.
In some cases, a special support frame may be necessary.
The roof installation of solar modules may affect the fireproofing of the house construction.
The modules are rated fire Class C, and are suitable for mounting over a class A roof. Do not install modules on a roof or building during strong winds in case of accidents.
