2 Maintenance of the mounting system
The mounting system must be checked for stability and operation at regular intervals during the system
maintenance.
Besides the visual inspection of the components, we recommend random connection checks.
The installation should be checked regularly for shady areas due to vegetation growth.
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 green 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.
On flat roofs without parapets, the modules must be mounted at a distance of at least 1.50 m to the edge of
the roof. On flat roofs with parapets, a minimum distance of at least 0.50 m must be maintained between
the module edge and the inner edge of the parapet, or rather, the distance to the edge must be taken into
account after the individual calculation in the planning software to ensure that the general conditions of the
wind tunnel tests can be maintained.
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 puncturing the roof. The photovoltaic system is secured against wind
suction with ballasting (substrate or suitable stones) on the basis of the results of the wind tunnel tests for
the system. The required substrate or ballast height must determined specifically for each project with the
planning software. The ballasting applies to the planned installation; deviations from the plan by the
installer may lead to different results.
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) = 1.50 m
-
Distance from system to parapet (inside edge) = min. 0.50 m
-
Module width = max. 1,34 m
-
Module length = max. 1,85 m
-
Angle of installation (fixed) = 10°
-
Distance between rows = see planning software Solar-Planit
The mounting system is designed for loads up to 2.4 kN/m² (2,400 Pa). The module is clamped (clamping
area 11 x 52mm) along the long side. Any potentially existing drainage openings on the module frames
must not be obstructed; the same applies to the formations on the supporting components designed for this
purpose.
