Asymmetrical clamping
Asymmetrical clamping means that the clamps on one and the
same long module side can have differing distances from the
nearest corner (see below). Make sure, however, that the
opposing clamps maintain the same interval from the
respective corner.
Asymmetrical clamping is possible under the following
conditions:
the expected pressure loads at the installation site
are a max. of 2400 Pa
modules are clamped on the long side.
This allows for the most freedom in planning the substructure.
For example, in vertical module on-roof installations, the
mounting rail pairs of the module rows can be arranged in
such a way that the mounting rails are spaced at differing
intervals, thereby making use of the mounting options to best
fit the height of the tile rows.

Symmetrical clamping
Symmetrical clamping means that all clamps on both (long or
short) module sides are the same distance from the nearest
corner.
Modules should always be clamped symmetrically in these
cases:
the pressure loads at the installation site exceed
2400 Pa
modules are clamped on the short side
The interval of the rails for a particular module row or column
can be different for each module row or column. This allows
for a certain degree of freedom with respect to the spacing of
the mounting rail pairs.
