Fig. 3 Permissible alignment of mounting
a : Parallel profiles for mounting; b: Parallel, aligned
fingers of a mounting system.
7.1.2 Impermissible alignment
Abb. 4 Impermissible alignment of mounting
a: Profiles are not parallel to each other; b: Profiles
neither parallel nor perpendicular to the PV module
edges; c: The profile ends for the side of a PV module
are not connected.
7.2 Clamp mounting for PV modules
7.2.1 Arranging the clamps
■ Permissible arrangement
Fig. 5 Permissible clamp arrangement for framed
modules
a, b : Symmetrical clamping on the long side
■ Impermissible alignment
Fig. 6 Impermissible clamp arrangements (1)
a: Missing clamps, b, c: Clamping on both short and
long sides.
Fig. 7 Impermissible clamp arrangements (2)
d: Protruding clamps, e: Opposing clamps have
different distances to the PV module corners,
f: Asymmetrical clamps on the short sides.
7.2.2 Clamp dimensions
Observe the following information for clamp lengths
and depths.
■ Clamp lengths and depths
Fig. 8 Definition of clamp length and depth for
framed PV modules
a: Clamp length, b: Clamp depth.
• The required minimum length of a clamp (parallel to
the frame side) is 30 mm.
• The required minimum depth of a clamp (perpendicu-
lar to the frame side) is 3 mm.
• We recommend a clamp depth of 5 mm.
• Depending on the ambient conditions (e.g. angle,
sucction load or tolerances of the substructure) a
higher minimum area per clamp may be required.
• The clamps determine the actual clamp depth and
length.
• Observe the instructions of the clamp manufacturer.
7.2.3 Tightening torque for clamp mounting
Tighten the screws on the clamp manually. If you use
an automatic screwdriver, then set a suitable maximum
tightening torque. You can find details for this in the
manufacturer‘s documentation for the substructure.
7.3 Screw mounting
7.3.1 Only for PV modules with standard frames
The PV modules have a mounting hole with a diameter
of 9 mm.
Note : The PV modules with 40mm frames have no
mounting holes
7.3.2 Tightening torque for screw mounting
For M8 stainless steel screws, use a maximum torque
of 24 Nm.
This applies to unlubricated screws with standard thread and strength
class of 8.8 (minimum breaking load 29.2 kN).
