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.

The load assumptions (load and roof division) are country-specific in accordance with the specifications of
the Eurocode load standards. The determination of the loads to be assumed for Switzerland is in
accordance with SIA 261.
At pitched roof, the modules may not be fitted above the gable end, ridge and eaves or the facade
(increased wind load). At the ridge the modules may be fitted up to max. a theoretical horizontal line with
the ridge tile and perfectly flush with the gable end. In the eaves area the modules may reach to max. the
end of the roof cover due to loads.
In case of an exposed building position (with wind load e.g. at the edge of a slope) or snow accumulation
(e.g. dormer or catchment grill or roof structures like domelights etc) the specifications of the Eurocode load
standards or SIA 261 (Switzerland) must be taken into account by the user within his own responsibility.
The design software does not consider these cases.
The static calculation of the mounting system is based on the symmetrical placement of the modules on the
mounting rails at the longitudinal side of the modules (roof-parallel clamping systems) or on the support
components (elevation) for equal load transfer into the substructure. For the insertion system a cross rail
arrangement is expected for equal load transfer.
The results calculated with the design software, such as distances of the fasteners (e.g. roof hooks, stock
screws, saddle clamps etc.), rail lengths and number of fasteners (e.g. direct attachment on the trapezoidal
metal), overhang (e.g. rail and roof hook protrusions) or distances between the base troughs and number
of fixing materials (e.g. rail joint)and the other calculation notes must be considered and complied with.
novotegra has been tested and certified by TÜV Rheinland:
2 Maintenance of the mounting system
The mounting system must be checked for stability and operation at regular intervals during the system
maintenance.
In addition to the visual inspection of the components, we recommend a random check of the connections
and the safe and correct position of the ballast on the base rails and ballast troughs.
Removal is possible in reverse order in the work steps mentioned below.
The maintenance work must be carried out by a specialist company with proven experience in electrical
systems and work on mounting systems.

3 novotegra for flat roof
The contents of this installation manual describe the installation of the substructure on roofs with sheet or
bitumen waterproofing, with or without gravel respectively substratum.
Depending on the roof seal material, separation and/or protection membranes may need to be added
between the roof seal and the substructure. This must be agreed upon directly between the company
installing the PV system, the building owner and the specialist roof sealing company.
The substructure is installed without penetrating the roof. The PV system is secured against wind suction
by providing ballast (e.g. suitable stones), based on the results of the wind tunnel tests for the system. The
required ballast is determined by BayWa r.e. Solar Energy Systems GmbH based on the project data
provided by the installation company. The ballast applies to the planned system; on-site deviations from
planning may lead to different results.
Protection against system sliding is verified based on a coefficient of friction of µ = 0.5. This value must be
checked by the installation company prior to installation. If the coefficient of friction is determined by the
installation company in advance, protection can be verified during planning using the determined value.
The system must be secured on site to prevent it from "creeping" due to expansion caused by temperature.
This can be achieved by installing suitable stop points on the roof surface or by anchoring to the parapet,
for example. The connection points on the building and building parts must be able to bear the forces
exerted.
General conditions to be observed in accordance with the wind tunnel test results:
- Roof incline 0 – 5 degrees
- Flat roofs with and without parapet
- Distance from system to roof edge (without parapet) = 0.50 m
- Distance from system to parapet (inside edge) = 0.50 m
- Module width = min. 0,92 m; max. 1,08 m
- Module length = max. 2,08 m
- Angle of installation (fixed) = 13°
- Distance between rows = 1.30 – 2.40 m (closed II) respectively 2.15 – 2.40 m (East-West II)
The installation system is designed for loads of up to 2.4 kN/m² (2,400 Pa). The modules are clamped on
the short frame side or, alternatively, on the long frame side in the corners (clamp surface 11 x 52 mm).
This requires approval from the module manufacturer for clamping on the short frame side or on the corner
of the long frame side. Any drainage openings on the module frame may not be blocked. This also applies
to the features provided for this purpose on the support components.

6 Warranty / product liability (exclusion)
In addition to the above-mentioned regulations and safety notices the applicable regulations and rules of
technology must be observed by the installing specialist company.
The installer is responsible for the dimensioning of the mounting system.
The installer is responsible for the connection of the interfaces between the mounting system and the
building. This also includes the tightness of the building envelope.
For flat roofs the roof insulation must be evaluated by the installer on site within his own responsibility
regarding the material of the sealing layer, resistance, ageing, compatibility with other materials, overall
condition of the roof insulation, need for a separating layer between the roof insulation and the mounting
system. The required and necessary measures or precautions for the protection of the roof insulation for
the mounting of the substructure of a PV system must be initiated by the installer with the aid of a specialist
tradesman where necessary. BayWa r.e. Solar Energy Systems GmbH does not accept liability for faulty or
inadequate measures and precautions for the protection of the roof insulation!
The installer must review the friction coefficient used in the calculation for the verification of the slip safety
of PV systems on flat roofs on site. Friction coefficients determined on site can be taken into account by
entering them in the Solar-Planit planning tool. BayWa r.e. Solar Energy Systems GmbH does not
guarantee the correctness of the assumed values and is not liable for damage due to the use of incorrect
values.
The specifications of the module, cable and inverter manufacturers must be observed. If these contradict
the mounting instructions, always consult the BayWa r.e. Solar Energy Systems GmbH sales team before
mounting the novotegra mounting system or – in the case of components not supplied by BayWa r.e. Solar
Energy Systems GmbH – the manufacturer concerned.
During the preparation of the offers for novotegra by our sales staff the local conditions are not always
sufficiently known, which is why changes to the offered quantities may result during installation. These
changes relate mainly to the number of fasteners for the building envelope (for example roof hooks). In this
