Dimensioning:
Two-layer systems are dimensioned in the same way as single-layer systems. However, the following
special features must be taken into account:

Plan for one roof hook per area where carrier rail and roof hook connecting rail meet.

Please also take into account the static values of roof hook connecting rails in addition to the roof
hooks and carrier profiles. Use the PV Manager software to determine the static dimensions.

We do not recommend you exceed a maximum carrier rail length of 3 rods (approximately 15,60 m)
due to thermal expansion.
