Ba-Wü photovoltaic requirement for old buildings - renewing roof tiles

for existing buildings it was decided at the beginning of 2022 and has been valid since Jan 1, 2023, and there hasn’t been any 1% financing for a long time.

Yes, and when a photovoltaic obligation was decided for non-residential buildings in 2020, it was completely unrealistic that this would ever apply to existing buildings when you completely redo the roof. Completely surprising and unforeseeable. If only someone had warned you before... At the beginning of 2023 there were still favorable financing options. Although the discussion is pointless anyway. The OP has the money and just wants to avoid it because he miscalculated. I have no sympathy for that. Stuttgart prices or not. The problem is not the place of residence anyway, but that too few people factor the necessary renovations into the prices. So exactly the cause of this problem
