For my new build, I am not planning a photovoltaic system initially, but I want to keep the option open for the future as much as possible.
Which cables should be installed from the meter cabinet to the roof so that a photovoltaic system can be retrofitted later as easily and cost-effectively as possible? How many cables? What cross-sections? How much space should be allowed for in the meter cabinet?

Well, it probably depends on the length of the pipe and the necessary work involved. If you already have a shaft, you just need to lay it in, but if you have to chip away (e.g., breaking up concrete) and so on, it takes longer and costs more.
I would say the basic option is around 50€ (approximately $55), and the more expensive option ranges between 200-300€ (approximately $220-$330).

Is it even possible to install cables of these dimensions afterward? The distance from the roof to the basement is quite long, and I can't imagine how you could even manage a bend with them. Exactly! That’s why I want to install them during the shell construction phase. Later on, they come up with some visually poor solutions that homeowners then accept because otherwise the costs skyrocket.
Photovoltaic cables should simply be laid during the shell construction. I still need to speak with more actual suppliers.
