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.
