Construction costs are currently skyrocketing

Self-consumption 30%, is PVGIS faulty (?), I also thought that was a transposition error! The abolition of the 70% rule would probably be the right step, but how often does a photovoltaic system achieve yields over 70% of the installed kWp? I have no experience there. For me, the orientation would be 40% east and 60% west, unshaded. Btt… with the current prices, one should definitely get some offers or maybe wait for more efficient modules. I think the development is currently being strongly driven.

My roof tiles have finally arrived after a good 5 months. So all the pallets on the right. The ones on the left are from my garden house and arrived one week after ordering

Possibly electricity costs given in the wrong unit? Or: Self-consumption means how much of your yield you consume yourself as a percentage. Also a pitfall.

No. All values are entered correctly...

Quick update from the interest rate front:

The 10Y bond SWAP is approaching the highs from June again :/ Today was especially wow (no clue if there will be setbacks again now)


Construction interest rates usually lag a bit, at Interhyp it currently looks like this in the trend, so still significantly flatter in the recovery...


Further development of course unclear. No idea if there’s currently fear of a rate hike at the beginning of September in there. Or "the inflation!!". Or what exactly o_O I wouldn’t want to make any predictions. My crystal ball says it can just as well fall again tomorrow as explode even more.

In this context, it may be worth adding that 5 years in the swap middle have now become just as expensive as 30 years. And also, that there is only about 0.30% difference between the cheapest term (5 years) and the most expensive term (15 years). No matter how you want to finance, really high prices are being called everywhere.

And also that between the cheapest term (5 years) and the most expensive term (15 years) there is only about a 0.30% difference left.

I find it particularly remarkable that with KfW 124, the 5-year conditions are currently (minimally) more expensive than the 10-year conditions. They have never been that far apart before, but I found that quite surprising. Perhaps it also shows that there is not much belief that interest rates will continue to rise in the medium term? (Although this insight doesn’t really help prospective builders much now?)
