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?

Why not include photovoltaics right away?
Depending on the type and size of the photovoltaic system, a 25-amp circuit breaker might be barely sufficient; you can also opt for a 40-amp breaker, which costs about 20€ more.
You don’t really need two meters, but usually every electrical panel has space for them.

Why not include photovoltaic panels right from the start? Surprisingly, it comes down to costs... with all the trades involved in new construction, expenses really add up, so you have to be careful. Photovoltaic systems seem to me like one of the things that can most easily be added later—especially if you prepare everything accordingly, which is what I’m trying to do right now.
I’m rather skeptical about the return on investment for photovoltaic panels anyway and believe that continuing decreases in photovoltaic prices will probably improve that situation over time. Considering the cost issue, I’ve therefore decided to postpone photovoltaic installation for now.
Well, photovoltaic systems are the only part of a house that actually generate a return; practically, you can never have too little money for that, as it reduces your expenses.
The payback period won’t improve any further; the peak has almost been passed. The modules cost practically nothing now, but the feed-in tariff keeps decreasing and may soon disappear entirely.
