Is preparing for photovoltaics in new construction sensible?

Hello

I am about to buy a new building from the developer

does it make sense to have a photovoltaic preparation so that it can be installed later?

what is needed as preparation? just an empty conduit?

Does it make sense to prepare for photovoltaic so that it can be installed later? What do you need as preparation? Just an empty conduit?

It definitely makes sense – we have two sufficiently sized empty conduits from the flat roof of the extension and from the attic of the main house to the technical room.

Yes, it makes absolutely sense to have empty conduits installed from an inexpensive roof entry point into a technical room.

ok
we have a gable roof how would a sensible preparation look like?
how thick do the empty conduits have to be?

we also need an empty conduit for the satellite dish, one could put both into 1 conduit

Even more practical than preparation is installing directly while the scaffold is still standing.

With us, this was done during the electrical installation. The specialist knows best what is possible and what is needed.
