Photovoltaic system: Costs, saving potential? - Experiences?

I would assume that the method remains the same. The EU is critical about that anyway because of subsidies.

I had understood so far that the amount of the EVG depends exactly on reaching the cap. If that falls, either a new one must be made or a new method? Or is that not true at all?

That is basically correct, but I assume that a similar type of calculation will be used. In my opinion, there will not be endless funding.

Unfortunately, ours can only go on the roof in one, rather two months. I hope that the time until then will still be sufficient.

Mine fortunately goes online on Monday. Although the registration was already in May

Huh? That interests me now. Especially because I consider your statement competent.
So far, I assumed registration only happens upon commissioning. I once read something about a “light bulb test.”
Does that mean you get the EVG from May?
