A support rail for a row of PV modules includes an outer hollow rail, a first inner hollow rail comprising a metal, and an insulating device configured to electrically separate the outer hollow rail from the first inner hollow rail. The first inner hollow rail is accommodated within the outer hollow rail via the insulating device and is held in all directions transversely to the support rail in a positive-locking manner within the outer hollow rail by the insulating device. |
