Photovoltaic obligation, at least 50% of the roof area

with us, there is the "new" obligation to equip at least 50% of the roof area with photovoltaic.

Please read in full, the "obligation".

I still consider the general law to be wrong.

if I derive from this that I once read about this obligation in another matter, there are many explanations and roof specifics that limit this 50% in an explanatory way. Therefore, there is no general 50%, but only the optimal 50%.

Good day, we now have the "new" obligation to equip at least 50% of the roof area with photovoltaic systems.

This is apparently regulated differently depending on the federal state. NRW, for example, requires only 30%, BaWü 60%, Bavaria only recommends it.

Bavaria only recommends it.

Since 2025 mandatory. See building regulations with the corresponding exceptions
