Hello everyone,
We are currently in the middle of the construction phase (the ground floor is completed, and we are waiting for the floor slab of the upper story).
Our house will have a simple gable roof oriented ENE-WSW (east-northeast to west-southwest) with two extensions, so there will be relatively little space left on the roof for a photovoltaic system (additionally, there will be a solar thermal system installed there as well). Our garage is located north of the house, so the building would block the sun from that side.
I recently came across solar terrace roofs and would appreciate it if anyone here has experience with them, both positive and negative:
Our terrace faces northwest, so it would naturally be shaded from direct sunlight until midday.
The theoretical maximum area available would be about 11m x 3.5m (36ft x 11ft).
If you need any further details, I’d be happy to provide them...

That would be quite disappointing, especially since anything beyond the usual modules (plus mounting systems) is rather rare and likely more expensive, so the return on investment doesn’t look very promising anyway.

I only just heard this idea today, as I’m about to request the first quotes.

.... removing the solar thermal system and only installing photovoltaics ;-) If that would even be an option. Unfortunately no – the plumbing and heating installation have already been planned and commissioned.

Alternatively:
Section 32, paragraph 1, number 1 of the Renewable Energy Act 2012: "For electricity generated from installations that produce electricity from solar radiation energy, the remuneration [...], if the installation is attached to, on, or part of a building or another structure and the building or other structure was primarily constructed for purposes other than generating electricity from solar radiation energy [...]."
Section 94 of the Building Code: "(1) Essential components of a property include items permanently attached to the land, especially buildings, as well as the products of the property as long as they are connected to the land. (2) Essential components of a building include the items incorporated into the construction of the building."
The disadvantage is that there is no guaranteed feed-in tariff of 12 cents per kilowatt-hour. Instead, compensation depends entirely on market rates, which can range from very low to nothing or even negative.
