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

We also dealt with this intensively in 2021. I was initially also in favor of metal or sandwich panels. In the end, they became normal inexpensive clay tiles. Roof tiles and battens were actually so attractive in terms of price that everything else would have been too much risk and effort.

Make sure that the dimensions of the roof match the photovoltaic system. If necessary, make the roof overhang 20 cm larger so that it fits properly. We fully covered East/West (distance between eaves and verge about 20 cm each). For the vents, we combined the individual lines in the attic so that there are not fans in the way everywhere.

North can or should also be covered!

Trapezoidal sheet metal + wood fiber insulation would also be a solution.

For a 14x14 house footprint, I would rather orient the roof (good decision to go for a gable roof instead of a hip roof!) East West to have more even sunlight exposure throughout the day.

if you can still rotate the roof, and walk towards the gable, you won't see your roof surface at all

I assume that the architect means a planning consultant of the construction contract partner, and by reviewing, that she tries to reconcile your wishes with their production capabilities?
A bungalow is per se not the economically first choice, and beaver tail tiles were never a favorite of clients – so this combination doesn’t quite fit together. The “100% south orientation” means a ridge direction W-E close to 27/09?

In principle, I find a "surface-mounted" solar module installation on a new building little to not contemporary, but that also has to do with the ideas of full coverage. In my conviction, a module does not need a "double bottom" but should be able to fully take over the job of the roof covering. But as I said, it makes a significant difference whether you are an autonomy seeker or a forced fulfiller of the politically fashionable will. A minimum requirement-alibi solar installation can be slapped on like an application when retrofitting an existing roof. For a “serious” solar/photovoltaic roof, I wouldn’t like a makeshift solution. The technology has had enough time on the market to be significantly more advanced than in its infancy. Such a roof module must not seriously want to compete only with a rattling bicycle mudguard.

From the north, it doesn’t seem to be a black hole or an anti-sun; at noon the sun stands in the fifth direction.

No, it is an architect and the construction is not being carried out by a prefab house manufacturer or similar. According to the development plan, the bungalow is the only feasible building form (number of floors I and height limited to approx. 5.5 m). Beaver tail tiles were preferred by the two roofers contacted so far. I cannot classify W-E close to 27/09 – does that mean west-east? North would also be covered – with regard to the in-roof solution this would certainly be nice and would be the first choice with an unlimited budget, but the price offer is at 500 EUR/m²(SunRoof). I would be very grateful for alternatives. Although I have seen some DIY solutions that enabled a watertight roof surface with Sika and aluminum profiles, but that was all in the area of sheds, carports, etc. and not on a house.

What does it then mean that she is "checking" the construction project? (Aero)nautically, "West" lies at 270° ("27") on the compass rose, "East" at 90° ("09"), yes.
