Construction cost breakdown, specific offer: improvement suggestions?

Yes, theoretically. But the companies we asked would have refunded us €100 for the EB if we had removed it from the contract. But we have now paid €5500....

Did you arrange the photovoltaic system with storage yourselves?

did you arrange the photovoltaic system with storage yourselves?

Yes, we are receiving the KfW 55 (without EE) subsidy and have additionally applied for the BAFA subsidy for the geothermal heat pump/controlled residential ventilation and cooling and received confirmation at the end of 2020. The photovoltaic system is outsourced. Storage is currently not worthwhile because there is no subsidy for it here in Brandenburg.

habt ihr die Photovoltaik mit Speicher denn selbst vergeben?

We managed the entire house ourselves in the end. The offers were more for us to get a good orientation on the total price for the bank.

The thought "everything is much cheaper" did not prove true. You read photovoltaic system 1000€/kwp, but the real offers are then 10,000€ for 5 kwp. Only if you do it yourself does it really get significantly cheaper. But we live at the wrong end of Germany...

Even in BW or Bavaria these offers exist. 2,000 € per kwp is simply just extortion.

Do you otherwise think that 4 kWp is sufficient? I haven't found exact figures so far except "common are 4-10".

It means: the more, the better. We are covering 2 roof sides completely on our bungalow. It is 13.29 kwp. The price per kwp also decreases the more you install.
