Construction costs are currently skyrocketing

One can only hope the government doesn't come up with the idea of making photovoltaics mandatory from 2023 for all new buildings... then the builders will be hit with additional costs of 10-35k again :/

I personally very much hope so. I can't understand this whining from you and other builders. You may perceive it as "being forced upon you", but please be aware that building is the ultimate luxury and the photovoltaic system is probably the only trade that pays for itself.

"One" in the sense of "I" really hope so. I can't understand this whining from you and other builders. You can perceive it as "forcing it upon you," but please realize that building is maximum luxury and the photovoltaic system is probably the only trade that pays for itself.

I wouldn't worry too much about new construction. This issue will be settled for the foreseeable future.

The latter, however, is currently not the case. Not even with an assumed lifespan of 20 years. I recently got a quote. I would have needed 80% self-sufficiency for it to pay off. And with a mandate, it would get even worse. And that wouldn't just affect homeowners, which might still be called a luxury. It would also affect rental apartments. And there we are probably no longer in the luxury segment. The apartments promised for the next few years can already be forgotten.

The latter just doesn't work at the moment. Not even with an assumed term of 20 years. I recently got an offer. I would have needed 80% self-sufficiency for it to pay off. And with a requirement, it would get even worse.

Just because your offer wouldn't have paid off doesn't mean that applies to everyone. But yes, currently finding a proper offer is not so easy. Ours from this year is fortunately definitely one. Depending on the crystal ball, prices will normalize again. Maybe we can agree on one of the statements "The photovoltaic system is probably the only trade that most likely/at all/partially pays for itself"? ;) As a Franconian, pardon Bavarian, I find it utterly unacceptable that the development plan still prescribes roof shape and tile color, but neither photovoltaic systems nor cisterns are required.

As a Franconian, pardon Bavarian, I find it absolutely terrible that the development plan still prescribes roof shape and tile color, but neither photovoltaic systems nor cisterns are required.

In our development plan, all sorts of things are prescribed, including the size of the cistern and even the preferred native tree species to be planted. Fortunately, the photovoltaic system is only “highly desirable.”

even the preferred native tree species to plant

And let me guess, they are almost exclusively large trees that you can either plant far enough away from the boundary or far enough away from the house but not both at the same time?
