Installation guidelines | 5
Important note!
Ensure you use the fastening sections as
indicated in tables 2 to 3.
Ensure that the mounting holes are correctly positi-
oned as in figures 2 and 3 when fitting the module
using mounting holes. You are also to use four corro-
sion resistant screws and nuts as per Table 1 and
washers with a minimum outside diameter of 12 mm
and a maximum of 14 mm.
When using clamps or direct attachment at the as-
sembly holes, the modules must be fastened flush to
the substructure at at least four points under as little
stress and tension as possible.
The solar module must be installed under as little
mechanical stress as possible and at a minimum
distance of 5 mm from the next module to allow for
any expansion in materials resulting from temperature
fluctuations.
Important note!
The substructure and solar module must
have the same thermal expansion coef-
ficient (e.g. aluminum).
Important note!
Solar modules must always be installed
in such a way that the cable inlets in the
junction box face downwards or side-
ways.
Ensure contact corrosion between the solar module
and substructure is prevented when different materials
are used.
Fasten the solar modules in such a way that they are
able to withstand all anticipated loads and any impacts
caused by weather conditions.
Use only corrosion resistant screws to install modules.
Ensure the support structure does not allow rainwater
or condensation water to reach the cable screw con-
nections in the junction box.
Warning!
The solar module must not stand in
condensation or stagnant water.

table 1: permissible fastening screws for direct installation
The supporting structure or substructure must be
adequately dimensioned based on a structural analy-
sis and adapted to the environmental conditions
locally to ensure that the maximum permissible de-
flection or deformation on the long side of the mod-
ule under a load of max. 4 mm is not exceeded. For
the short side, there is a max. value of 2 mm. You also
need to ensure that the module does not distort or
warp more than 10 mm across its diagonal line. Only
one of the named deformations is permissible in this.
Figure 1: Permissible layout of the fastening points and installation
profiles
The solar module can be attached with clamps, lay-in
systems or, alternatively, directly to the assembly
holes. If clamp systems are used, the clamp contact
surface must be at least 400 mm² for each fastening
point. Furthermore, under all conditions, the surface
area must be min. 400 mm² for each fastening point.
