05. System planning
The planning and static calculations of AeroFix 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 assess the degree of utilisation and the suitability of the assembly components for your roof.
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
For roof pitches >3° is required securing the module fields in the direction of the roof pitch. This can be
done for example with east-west orientated roofs using a ground rail coupling to be taken across the roof
ridge.
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).
AeroFix 15-S and AeroFix 10-S must be separated at the latest after 15 rows and after 15 modules in the
row.
AeroFix 10-EW must be separated at the latest after 14 rows (7-V rows) and after 15 modules in the row.
The field beginning and ending with modules is not counted as a row.
