10.4.2 Modules with Solrif® frames
NOTE
Avoid screw mounting for Solrif
mount Solrif
modules with the Solrif

system.
10.4.3 Tightening torque for screw mounting
For M8 stainless steel screws, use a maximum torque of
24 Nm.

Insertion mounting
10.5.1 Modules with standard frames
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
Ch. 8.4.1: „Intervals between modules with standard
frames"), aleo solar recommends mounting at intervals.
10.5.2 Modules with Solrif
Only mount modules with Solrif
mounting system.
10.6
Load levels
A load can be a pressure load as well as a a suction load.
Loads from snow and wind are grouped into three levels,
which need to be taken into account wherever the module
is installed. Higher load levels make the requirements for
proper installation more stringent. The values listed below
assume an appropriate installation.

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. This applies to portrait mounting
and clamping on the long side (observing the permitted
clamping positions, see chapter 10.8).
Possible measures are: Snow hooks on the lower module
frame, frame fixings or an additional substructure rail with
standard end clamp, in the middle of the lower frame part.
