Construction costs are currently skyrocketing

Somehow your post confuses me a bit :-D
In the first paragraph, you question the constellation (East/South/West) and in the next, you suggest exactly that. ;-)
Or did I misunderstand you?

I meant that covering 3 surfaces with only a few modules with 24 modules was nonsense. So then everything on the south side, to at least power one surface.
Or cover everything but with the difference FULL. Where I assumed that this can be represented with significantly more than 24 modules. Even if it's a hip roof, that should be possible. Or is the surface really that small? ;)

You see. Exactly for this reason (because it is so complicated) Germany is hindering the energy transition

We here in Bavaria with our government do that all by ourselves already :)

The new regulation is indeed simpler, but it is likely financially disadvantageous because depreciation on the asset would then also be eliminated?

Did you finance the asset? Or pay from equity? That is a huge difference. I have no financing and therefore no interest as operating expenses and thus fare better with the new regulation.

Or just cover everything but with the FULL difference. Where I assumed that could be represented with significantly more than 24 modules. Even if it’s a hip roof, that should work. Or is the surface really that small? ;)

So with 6 modules the south side is absolutely full. East and west each with 9 modules. The house measures 9 x 11.5m, so there is really hardly any space on the roof. 24 modules is already so tightly packed that the modules have to be mounted offset, which obviously doesn’t improve the appearance.

hmm something is wrong. What roof pitch do you have? My house dimensions are also about 9x11 and in my planning 24 modules fit on two sides. all four fit 48.

Did you finance the system? Or pay with equity? That is a huge difference. I have no financing and therefore no interest as operating expenses and am better off with the new regulation.

Since one has to prove a profit motive anyway in order not to fall into tax-ineffective hobby activity, that is pretty irrelevant. Profit motive ultimately means that one pays taxes in total (8-year period) and does not save them. By the way, that has zero to do with the VAT regulation. ;)
