BayWa novotegra closed II Mounting Instructions page 4

The roof cover / roof construction / facade must meet the requirements of the mounting system with regard
to load bearing capacity, support structure and condition.
Requirements for the material of the roof construction / roof cover / facade:
Wooden components (rafters/purlins): min. strength class C24, no fungus infection or rot
Tensile strength Rm, min for trapezoidal metal: steel 360 N/mm²; aluminium 195 N/mm²
Wall construction material: concrete, brick or sand-lime brick in solid or hollow block design.
The load bearing capacity of the roof / roof construction (rafters, purlins, trapezoidal metal, concrete floors,
number of adhesive points, folded seams, etc.) or the facade (wall construction materials) must be checked
by the user or a check be commissioned.
Physical building aspects concerning insulation penetrations (e.g. condensation) must be taken into
account by the user.
Notes on mounting
The components of the novotegra mounting system are intended exclusively for the attachment of PV
modules. Dependent on the roof type of the building the designated mounting system components must be
used.
A condition for the intended use of the novotegra mounting system is the mandatory compliance with the
specifications in these instructions regarding safety information and mounting.
In case of unintended use and non-compliance with the safety information and mounting instructions and
non-utilisation of the corresponding mounting components or use of third party components not belonging
to the mounting system any warranty and liability claims against the manufacturer are voided. The user is
liable for damage and resulting consequential damage to other components, such as PV modules, or the
building as well as personal injury.
The user must read the mounting instructions prior to mounting. Unresolved issues must be clarified with
the manufacturer prior to mounting. The mounting sequence in these instructions must be adhered to.
It must be ensured that a copy of the mounting instructions is accessible in the immediate vicinity of the
work on site.
The mounting specifications (module load, attachment, clamping areas etc.) of the module manufacturer
must be observed and complied with.
Prior to mounting the mounting system must be statically calculated with the loads to be assumed for the
building project in accordance with the national standards. Information relevant to mounting (e.g. roof hook
distance, lengths of bolts, overhang and protrusions or distance of base trough and required ballast) must
be determined by the static calculation using the design software www.solar-planit.
The permissible roof inclination for using the mounting system according to these installation instructions is
0 to 60 degrees for roof-parallel installation on a pitched roof and 0 to 5 degrees for elevated installation on
a flat roof. Facade systems must be mounted parallel to the facade.
For roof-parallel installation with the clamping system, two module support rails per module must be
mounted symmetrically under the modules for equal load transfer into the substructure. Alternatively, the
roof-parallel installation can also be installed with insertion rails.
The specified tightening torques must be adhered to and checked randomly on site.
Notes on static calculations
The mounting system must generally be statically calculated for each individual project using the design
software Solar-Planit. Excluding façade systems, the calculation for this will be carried out by the company
BayWa r.e. Solar Energy Systems GmbH.
The static calculation only determines the load bearing capacity of the novotegra mounting system and also
takes account of the attachment to the building (rafters, purlins, trapezoidal metal, facade etc.). The load
transfer within the building is not considered (customer static calculations).
The load bearing capacity of the mounting system components is determined on basis of the planned
module layout and the underlying building information (project data recording). Deviations from the
planning on site may lead to different results.
