How important is the "traditional" roof in times of photovoltaics?

What do you mean by that?

In my US house, the popping noises were not as noticeable (they use a lot of permanent elastic adhesive when installing), but there was no intermediate ventilation or anything like that, and there was quite a bit of condensation – but that was probably more due to the general construction.

Yep. With that you don’t have any problems here in Germany. They build "properly" there.

I don't even mean loud banging noises, but at first I felt more like I was living inside a guitar or a cello. The material (metal-PUR/PUR-metal) certainly has hardly any sound insulation compared to wood fiber insulation boards or similar, of which we should have at least placed a thin board in between. Overall, I wouldn't see any real advantage over the traditional construction method.

Normal, cheap flat tiles and full-surface photovoltaics on both sides; in the end, I think you will like it that way too. With a sandwich roof, I would be concerned about noise, which was even a problem for us, although we live in the countryside. The rafter insulation works great against temperature but quite poorly against noise, so we even heard the neighbor's trash can lid or loud wind noises. In the end, we solved it, but we probably should have added a soundproof intermediate layer.

Interesting aspect with the noise problem. I would have also thought of insulation between the rafters. I still need to get quotes from roofers for the price – so far the offers are quite expensive. Even with the cheapest tile (Braas Opal Bieber) and 24x10 rafters.

Then this problem does not exist. Personally, I like exposed beams much better, and I believe that insulation above the rafters also offers some advantages. In general, compared to previous houses, I now know that top insulation should have an immensely high priority.

You mean in the US they don't build properly?
