Construction costs are currently skyrocketing

hmm something is wrong. What roof pitch do you have? My house dimensions are also about 9x11 and in my planning 24 modules fit on two sides. all four sides would fit 48.

We have 30 degrees. I have already increased the area coverage from 8 modules to 9, more is absolutely not possible with a 30 degree roof pitch.

A hipped roof is not just a hipped roof. If it turned out unfavorably, it only has a narrow triangle to the south because east-west are each trapezoids and the house is rectangular with the narrow side facing south. If there is also a roof window, the roof area is rather small.

That's exactly right, except for the roof window, we don't have any because it is a full story.

Ok, I have 25° - maybe that's the reason. I wouldn't have thought it made such a difference.

Bungalow 12.20 x 9.60, roof pitch 30°, roof overhang 60 cm, 13.68 kWp.
30 module house, 23 modules south 32° azimuth, 7 modules southeast -58 azimuth. In addition 6 modules garage. In total 36 Trina TSM-380-DE09.05 Fullblack (exactly 1 pallet), built 10/21, commissioning 01/22. Production to date 14,300 kWh. Costs slightly over 11 thousand euro net.

Yes, exactly the same would apply proportionally to me if you were to use three pages. 24 on three pages is 50% or 33% too little.

I just did a very basic calculation with numbers from two years ago and today.
The reference only concerns the monthly burden to the bank, assuming the land and ancillary building costs are financed from equity.
These values are really tough and should approximately correspond to reality for a single-family house, upper standard, gable roof 160m2.

Sorry, but 500k pure construction costs still seem too much to me. Additionally, comparable annuities would be interesting. But then with different interest rates. In one financing you are at just over 3%, in the other at 5.5%. I find that hardly comparable.
