4 Installation guidelines
Important Notice!
Definitely align the solar module so as to avoid a
shadowing effect (even to a temporary or partial
extent: e. g. due to roof dormers, trees), since this
can lead to damage in the solar modules (e. g. forma-
tion of „hot spots"), failure of the PV generator and
loss of output.
The additional loads which arise by way of the weight
and the structural attachment of the PV system are to
be included in the structural analysis of the overall
construction.
Verifications of stability, deflection and load parame-
ters are to be initiated by the constructor or the
operator of the system.
Install the modules on a sufficiently-dimensioned,
load-bearing and permanently corrosion-resistant
substructure.
Observe the specifications for mounting areas accor-
ding to Illustrations 1 and 2.
Attachment with clamps on the narrow sides of the
solar module may not be performed.
The attachment of the solar module can be perfor-
med with clamps (or as an alternative, directly on the
installation holes). When clamping systems are used,
the clamp surface per attachment point on the mo-
dule must amount to at least 400 mm².
Position of the installation drill holes in accordance
with Illustrations 3 – 6
Per module, four non-corrosive screws and nuts (and
grommets with min. 12 and max. 14 mm exterior
diameters) are to be used in accordance with Table 1.

The modules must be attached flush to the substruc-
ture (without tension and deformation) at no less
than four points.
The substructure and the solar module must have the
same heat-expansion coefficient (aluminum).
Contact corrosion between the solar module and the
substructure is to be avoided when different materi-
als are used.
Attach the solar modules so that they with-stand all
foreseeable loads and weather-induced influences.
Only use non-corrosive screws for the installation.
The solar module must be installed without mechani-
cal tension and (to compensate material expansion
due to temperature fluctuations) with a minimum gap
of 5 mm to the next module.
Particularly in exposed locations, sufficient lightning
protection is recommended.
Integration into existing lightning protection systems
must occur in observance of the valid regulations.
Only install solar modules edgewise (or crosswise),
with the connector socket facing upward.
In the course of elevation, it must be ensured that no
rainwater or condensation water can run in the direc-
tion of the cable screw connections on the connector
sockets.
The solar module may not stand in tail water or con-
densation water.
