Which empty conduit is suitable for photovoltaics

Moinsens,

we are hopefully going to build a carport soon. I want to prepare conduits for photovoltaics in the gable roof. Which conduit do you recommend?

2x M25

Alternatively, just use a suitably sized supply line into the house. You can also hang the inverter in the carport or outside.

or 1x M40

It is called plastic armored conduit at least M32. During installation, make sure to avoid 90 degree bends. In the visible (roof) area, use UV-resistant (which is then black).

Thank you, then I know what I need to get.

It depends on the system and the arrangement. Cabling requirements can vary. As a rule, the recommended thin tubes are sufficient. If not, it was foolish not to have informed yourself specifically.
