MODULE INSTALLATION
The module may be installed in various applications utilizing a variety of support structure options and
attachment methods. For optimal performance in all applications, clearance, 4 in, between the module frame and
the mounting surface is required to allow cooler ambient air to circulate around the back of the module.
BUILDING ATTACHED: The modules are commonly supported parallel to the surface of the building wall or roof.
When installed on a roof, install modules on a fireproof roof cover. Clearance between the module frames and
surface of the wall or roof is required to prevent wiring damage and to allow air to circulate behind the module.
Do not fully enclose the photovoltaic array, as solar modules perform best when cool in temperature. If other
mounting means are employed, this may affect the listing for Fire Class Ratings.
FREE STANDING: The supporting structure is used to mount modules at correct tilt angles. The mounting design
may have an impact on the fire resistance. The module may be attached to a support structure by the following
methods:
STANDARD: Utilizing M6 bolt through the existing mounting holes in the module frame and then through module
mounting holes on the support structure. The M6 bolt used for securing the module frame should secure with an
applied torque of 15 ~ 20 Newton-meters.
Refer to the Module Drawings for figure1 ‘Mounting System’.
CLAMPING: Top or bottom clamping methods certified by a registered professional engineer, and in compliance
with local codes. The applied torque is same that of standard mounting.
OTHER: Other method(s) certified by a registered professional engineer, and in compliance with local codes.
Note
The module endures the 30 lb/ft2 of mechanical load to front and back of the module.
It is not allowed to dismount, drill or modify the frame or any other part of the PV module. This may cause the
loss of warranty. Please contact Technical Service Contact if module mounting procedure is not clear
In order to achieve maximum annual yield, optimum orientation and tilt of
PV module is necessary. Sunlight shining vertically and completely onto
PV module is the best condition to generate maximum power.
Artificially concentrated sunlight shall not be directed on the module.
Very hot module(s) can reduce power output performance.
Ensure the module has good ventilation conditions to prevent overheating.
Site-specific environment loads such as wind and snow should be taken
into account to avoid exceeding the maximum load 30ibs/ft
2
.
When designing the system, please pay attention to the total voltage
(if connected in series) and current (if connected in parallel).
We recommend the maximum number of modules in parallel should be
no more than four (4), and while in series, no more than the ratio of
module`s maximum system voltage to open circuit voltage.
(Maximum system voltage: 600V for UL product)
The module must not be installed close to fire or flammable materials.
Completely cover the module with an opaque material during
installation to keep electricity from being generated.
The products should be installed in locations that are not accessible to
contact under working conditions.
