3.2  Preliminary planning for mounting the  

installation

Some preliminary planning is necessary before starting to 

mounting the system. 

Selecting the suitable constructions and rafter con-

figuration

Calculate the available connected roof surface and rafter 

distance for the installation. Select the suitable CENPAC 

construction based on the roof dimensions and the nec-

essary 

overall dimensions 

of the CENPAC constructions 

(see chapter 3.1). A choice must finally be made from the 

rafter  configuration  plans  (see  installation  instructions) 

that corresponds to the distance of your rafters. Proceed 

in accordance with chapter 3.3 if there is a difference in 

rafter distances.

Positioning the PV installation

Position your CENPAC bearing in mind the 

Generator field 

dimensions

as close as possible to the centre of the roof. 

Bear in mind that a 

margin

 of at least 500 mm must be 

observed at all times. The actual mounting can now begin 

(chapter 4). 

If the distance relating to your rafters differs from that in 

the drawings and you cannot carry out your 

rafter con-

figuration

  yourself in accordance with chapter 3.3, please 

contact your local Centrosolar office.

3.3  Rules relating to individual rafter  

configuration

P

P

Rafter distances of 600 – 800 mm are permitted

P

Max. range that can be straddled with the module 

supports: 1,500 mm 

P

Permissible cantilever: 50 – 400 mm

Carry out the rafter configuration on the sides of the 

generator field on the two outer rafters

P

P

Twice  the  number  of  roof  hooks  on  the  2-C  groove 

profiles  in  the  border  of  the  generator  field  (to  the 

ridge, the eaves and the verges)

P

P

Module support profiles must be fixed on at least two 

2-C groove profiles

Terminology

 

Overall dimensions

The overall dimensions state the free roof space that must 

be available for the installation of the complete CENPAC 

system in order to enable the CENPAC to be installed on 

your roof safely. The overall dimensions also included the 

necessary margins and an additional rafter adjustment 

area as well as the generator field dimensions.

Generator field dimensions 

The generator field dimensions are clear from the genera

-

tor surface of all PV modules of the complete CENPAC 

system. 

Margins 

The margins stated here are safety-relevant distances of 

500 mm to which your PV installation must at least adhere 

to the eaves, the ridge and the verge of the roof. 

Cantilever

 

The cantilever is the overhang of the module support pro-

files over the external 2-C groove profile in the generator 

field. The permissible cantilever may be between 50 and 

400 mm. During the preliminary mounting planning, the 

cantilever is defined by the overhang of the module sup

-

port profiles over the centre of the outer rafters.

Rafter configuration plans

These are CAD plans for the rafter configuration on the 

roof. These plans for the rafter distances of 600, 650, 700, 

750 and 800 mm for the individual  constructions of the 

complete CENPAC system are enclosed. They explain 

the optimal configuration of the rafters by way of the en

-

closed roof hooks, the positioning of the mounting profiles 

as well as the cantilever to be applied.
