Decision KfW55 vs. KfW40 plus

Hello everyone, I obtained the missing information from GÜ:

[*
Photovoltaics + storage: Minimum according to KfW requirements, i.e. about 2.7kWp for us [*]Additional costs broken down (net): [LIST] [*]Photovoltaics + storage: €13,000 [*]Planstein 42.5 cm + additional insulation: €8,000 [*]The central ventilation system was already included in the price and is therefore not part of the surcharge for KfW 40 plus! Omitting it would of course be possible and would bring a saving of €4,000.

Then the KfW 40 plus package probably really doesn't pay off economically for us. I will now get offers for a maximally large, turnkey photovoltaic system. Do you have any tips on how to find providers who deliver high-quality work?

These are the additional costs from KfW55 to KfW40+, right? Then you get €10,000 more repayment subsidy compared to KfW55. However, the price for the photovoltaic system seems a bit high to me and 2.7kWp too small. I would install a photovoltaic system anyway; it is an investment that pays off sooner or later. And with KfW40+, you basically get the storage as a bonus through the repayment subsidy. Otherwise, a storage system would probably not be worthwhile.

The photovoltaic system shown here is a bad joke.

But one must not forget that this also comes with a feed-in cap, which pretty much eats up the grant again.

soft 70% and done?

What exactly do you mean by the feed-in cap?

No, with KfW it's only 50 or 60 now, which is noticeable compared to the 70.
