the guarantee. The installation supporting rail must be tested by the third-party organization with the analysis
ability of Static Mechanical according to the local national or international standards.
6.1.2
The supporting rail must be made of environmental corrosion, anti-rust and UV-resistant materials.
6.1.3
Modules must be securely fastened to the supporting rail.
6.1.4
Drilling holes on the surface of module glass or drilling additional mounting holes on module frames
may void the warranty.
6.1.5
Forces generated during thermal expansion and contraction of the supporting rail may influence the
performance and use of the module, so make ensure that the minimum distance between two neighboring
frames is 10mm, but in order to ensure good ventilation. Suggest this distance between two neighboring
frames is 30mm.
6.1.6
In areas with large snow cover in winter, select a higher mounting bracket so that the lowest point of the
module will not be covered by snow for long periods of time. In addition, the lowest point of the module is
high enough to prevent the module from being obstructed by vegetation or trees.
6.1.7
The bearing surface of the supporting system must be smooth without any twist or deformation, and all
of them shall be at the same height without dislocation.
6.1.8
The module mounting method does not result in electrochemical corrosion between the aluminum frame
of the module and the different metals.
6.2 Three kinds of Mounting
6.2.1
Roof mounting
6.2.1.1
It is necessary to provide a special supporting rail for the roof mounting. When installing a module on a
roof or building, ensure that it is securely fastened and cannot fall or be damaged as a result of strong winds or
heavy snow. During roof mounting, check the building codes being used to ensure that the building and its
structure where the module is installed have adequate bearing and sealing capacity. The roof when penetrated
during module installation shall be properly sealed to avoid rainwater leakage.
6.2.1.2
To be suitable for operation, reduce steam condensation and facilitate the ventilation & heat dissipation
of the module during tile installation, the module shall be parallel to the wall or roof surface of the building,
and the distance between module and surface of the wall or roof shall be at least 50mm to prevent wiring
damage and to allow air circulation, ventilation and heat dissipation behind the module. For stacking type
installation, the module shall be installed on the fire-resistant roof. The Fire Resistance Rated Class of the
modules is Class C, and the modules are suitable for mounting on an above Class A roof. Do not install
modules on a roof or building during strong wind.
6.2.1.3
For the roof system installed in the area with relatively heavy snowfall or snow cover in the
meteorological records, the installer shall reinforce the supporting system at the lower frame of the module, in
order to prevent the lower frame from being pressed and damaged by the falling snow or freezing of the melt
ed snow. Sunerg Solar suggests selecting the support reinforcing mechanism shown in figure 3.
