2 Installation Assembly Rules
2.1 Assembly Notes
Modules must be handled with care during installation. Impacts to the front and rear or the edges can
damage the modules.
For a roof assembly, ensure that the structural dimensions (consult a structural engineer, if applicable) of the
roof are adequate for bearing the loads imposed by the photovoltaic system.
We recommend positioning the solar modules at an angle of at least 10° to a maximum of 75° to the ground.
Struts, mounting clamps, screws and other fixing elements must be commercially available and corrosion-
free and must fulfill the requirements of DIN 1055. In particular, the fixing elements must be designed in
accordance with the local wind and snow loads to DIN 1055-4 and 1055-5.
The modules are to be mounted in such a way that melt- and rainwater can run off freely and that the module
will not be constantly wet.
The solar modules are suitable for installation both with their long side up and their short side up. (see 2.2
Assembly Variants)
Take note of the position of the connection socket.
When using mounting clamps, the solar modules are to be mounted on the struts in at least four locations on
opposite sides. The clamps must be positioned inside the mounting zone.
The module must be securely fixed. The clamps must not be in contact with the front glass or deform the
frame in any way.
Avoid shading effects from the clamps and mounting system.
Module can be mounted with bolts at 4 (four) or 8 (eight) symmetrical quarter points.
The modules must be mounted with a minimum distance of 5 mm to the next module.
Use corrosion-proof mounting materials.
Do not drill any holes into the module and module frame.
The maximum tightening torque for the mounting clamps and bolts is 14 Nm.
In order not to impair the modules’ energy yield, their installation in shaded areas (by trees, buildings, etc.) is
to be avoided.
An installation of the modules as overhead glazing is not permitted.
Modules should only be installed in such a way that sufficient back ventilation is ensured.
Modules become warm and require an adequate air flow for cooling.
Water drainage openings in the module frame must not be closed in any way. The mounting frame, too, must
not obstruct them.
The earthing holes provided only serve for the purpose of earthing the frame.
Operation of the solar modules in regions with snow loads of up to 5400 Pa is dependent on the assembly
and module type (see 2.2 Assembly Variants).
Ensure that no flammable gases can occur near the installation site.
In a roof installation, the module must only be mounted above a fireproof roof cover approved for this
application.
