6. System planning
The planning and static calculations of AeroFix / AeroFlat flat roof systems is carried out using IBC PV
Manager software or based on the checklist to be submitted with the associated module layout plan, which
can be used to determine the part list and ballast plan.
The proof of the plant safety and the static load capacity of the system components have to be
calculated for every single project!
Before initiating the planning phase, there must be an extensive check of the existing building and
technical documentation must be completed. In particular, the constructor should be informed of any
damage to the roof cladding. The functionality of existing roof waterproofing should be provided for the
operating period of the new PV system to be installed.
Drainage
The customer must check that the structural condition is consistent with the design (building size, roof
pitch, roof cladding, obstacles etc.).
It must be ensured at all times that rain water is discharged to drainage collection points and this should be
incorporated into the planning of the PV system.
Pitched roofs
See 10. System security device
Roof covering
The AeroFix / AeroFlat flat roof system can be built on bitumen, foil, concrete gravel an green roof.
Basically, the building protection mats of the base rails should lie completely on the roof skin. There should
not be any objectsunder building protection mats that could damage the roof skin, e.g. sharp objects,
stones etc.
For gravel roofs, the gravel should be removed from the base rails. If this is not possible because the
thikness of the gravel, e.g. because the modules are coverd by the gravel, then the base rails can be laid
on the gravel and shaken a little. One must ensure on site that the weight of the PV system does not push
anything through the roof membrane.
For green roofs, it is recommended that a growth barrier is laid over the entire surface and glued to th
joints. This prevents plants from growing in the gaps between the modules. A loss of module yield due to
shade can be avoided.
Restriction of module field sizes
Due to different linear expansion coefficients for the structural profiles compared to those for the roof
cladding, there may be thermal constraints on the roof waterproofing. This is excluded by restricting the
module field sizes (splitting individual module fields). The thermic separations must not be between the
clamping points inside a module. The center to center distance is continued normaly via the separations.
