Correct mounting location
The module must not be mounted as overhead gla
-
zing, e.g. on a facade. In addition to the module itself,
the mounting system must also be able to easily wi
-
thstand the expected load from the conditions at the
installation site (snowfall, wind).
The underside of the module frame is provided with
openings that allow precipitation water to run off. Du
-
ring installation, make sure these openings are not
restricted in their function.
If used in an upright installation, the socket can be
mounted pointing upwards and downwards. Other
-
wise only installation with the junction box facing
upwards is permitted.
Assuring yield through optimum alignment and
inclination
We recommend planning the suitable orientation and
correct tilt angle of the modules before installation,
so that the system can achieve optimum yield perfor
-
mance. Ideal conditions for power generation prevail
when the sun‘s rays hit the generator surface per
-
pendicularly.
To avoid any loss of performance when connected in
series, please make sure that all modules are instal
-
led with the same orientation and inclination.
Installing the module free from shade
Even slight shading reduces the yield from the sys
-
tem. It is therefore particularly important to install the
module as free of shading as possible. There should
be no full shading throughout the year, and unhin
-
dered exposure to sunlight should be ensured for
several hours, even on days when the calendar is
unfavourable.
Ensuring sufficient rear ventilation
Sufficient rear ventilation ensures that performan
-
ce-reducing heat accumulation can be avoided.
Secure mounting
In order to mount the modules as intended, they
must each be securely fastened by at least four
points. Framed PV modules may be clamped on the
short and on the long sides.
NOTE: Ensure that the maximum mechanical load
capacity of the modules is observed, taking into ac
-
count the wind and snow load zones as well as the
terrain category and building height.
Instructions for installation
The modules can be connected to the substructure
in various ways: either by clamping the modules from
the front (see example 1) or by screwing the modules
into the mounting holes provided from behind (see
example 2).
Use a torque wrench during installation. The tigh
-
tening torque to be applied in the examples shown is
20 Nm. Use M6 V2A screws for installation. Only use
the existing drill holes for installation. The drilling of
further holes would lead to a loss of warranty.
Loads
Depending on the type of mounting, the solar mo
-
dules are able to withstand the respective load. In
principle, make sure that the solar modules are not
subject to unnecessary stress.
When using the clamp-on mounting method (see
example 1), the fixing points in extended clamping
areas must be taken into account. A graphic repre
-
sentation of the clamping areas can be found on
page 10.
Please note that failure to comply will void any claim
on corresponding warranty services.
