Of course it's possible, if necessary with a ladder and inclined lift or lift platform. Unfortunately, not all photovoltaic installers do this and it can sometimes be more expensive.
Then I'll think about it in 20 or 30 years when the time comes.
It definitely makes sense to think about it in advance and not only when the situation is irreversible. Not that the helicopter has to be used then. :D

Therefore, it also makes sense to install the mounting frames (base structure) already during the roof construction. The solar panels can be placed on top later.
The installation of photovoltaic modules is child's play. The substructures are sometimes so simple - for example T Werk - that the assembly of a Pax cabinet seems like a journeyman's piece in comparison. With your house, you can determine the order however you like. Either way works.
Thank you very much, now I am relieved for the time being. I thought I would have to choose one of the two. The half of the roof facing northeast is certainly not worth equipping with photovoltaic panels, is it? What do you think about a photovoltaic patio roof?
