10.3 Clamp mounting for modules with Solrif® frame
HINWEIS
Avoid clamp mounting for modules with Solrif® frame. Only
mount these modules with the Solrif® mounting system.
You can also contact the aleo solar branch in your country.
They will provide you with information on mounting systems
which are already in use on a greater scale.
10.4 Screw mounting
10.4.1 Modules with standard frame
The aleo modules have mounting holes with a diameter of 9 mm.
10.4.2 Modules with Solrif® frame
Avoid screw mounting for Solrif® modules. Only mount Solrif®
modules with the Solrif® mounting system.
10.4.3 Tightening torque for screw mounting
For M8 stainless steel screws, use a maximum torque of 24 Nm.

10.5 Insertion mounting
10.5.1 Modules with standard frame
Observe the manufacturer’s instructions for the mounting system.
Use the earthing holes for the potential equalisation.
Although edge-to-edge mounting is possible (see also chap. 8.4.1:
„Intervals between modules with standard frame“), aleo solar
recommends mounting at intervals.
10.5.2 Modules with Solrif® frame
Only mount modules with Solrif® frame with the Solrif® mounting
system.

This applies to unlubricated screws with standard thread and strength
class of 8.8 (minimum breaking load 29.2 kN).
10.6 Load levels
A load can be a pressure load as well as a suction load. Loads from
snow and wind are grouped into several levels, which need to be
considered wherever the module is installed. Higher load levels
make the requirements for proper installation more stringent. The
values listed below assume an appropriate installation (see chap.
10.7: “Mounting drawings for modules with standard frame”).
10.6.1 Permissible loads for modules with standard frame
42mm
10.6.2 Permissible loads for modules with standard frame
35mm
10.6.3 Permissible loads for modules with Solrif® frame
Please observe the instructions from Schweizer for the mounting of
modules with Solrif frame. You can find the manual on the website
from Ernst Schweizer AG Metallbau or on aleo solar website:

.
10.6.4 Snow load
For snow loads above 3900 Pa, suitable measures must be taken to
ensure that slipping snow loads do not damage the lower module
frame.
Possible measures are: snow hooks or module holder, in the middle
of the lower frame part.
CAUTION!
These measures only serve as a support for the frame and not as an
additional fastening point. Clamps fixing the frame are therefore
not suitable for this purpose!
For snow loads above 3900Pa, aleo recommends horizontal instal-
lation with clamping on the long side.
