ᐅ Expanding a Photovoltaic System on a Garage After Initial Installation?

Hello everyone,
My girlfriend and I have decided to carry out our building project with Viebrockhaus.
Since we are building to KfW40+ standards, we need an appropriate photovoltaic system on the roof.
Unfortunately, our house is not optimally, or rather very poorly, oriented.
Rotating the house is not an option (partly because we don’t want to, and partly because we have to comply with a building line/ setback).
We have now considered installing the standard modules for KfW40+ on the roof and later adding an extension on the flat roof of the future detached garage.
Is this even possible? What preparations would need to be made in advance? The detached garage will be built by ourselves (unfortunately only after the main house is completed, as the area has to be used as a staging area beforehand).
This way, we could ensure an optimal orientation.
I would be very grateful for your advice and tips.

And I’m not worried about the neighbors; we have only one, and he has installed two solar thermal panels on his garage himself.

We had to provide proof for the repayment grant to the KfW within a maximum of one year after moving in. The photovoltaic system was connected to the grid shortly before that, and no one complained.

I think you’re overthinking it. Very few roofs are perfectly oriented to the south.
