Renovation of a 1960s house: Questionable expert recommendations?

The Renewable Energy Act clearly regulates this. Guaranteed remuneration for 20 years upon commissioning. That doesn't change.

I am not quite sure which loophole you are talking about. This is a subsidy. Not a secret offer known only to tax advisors. This offer has existed for over 20 years and anyone with a roof can use it. Those who took advantage of it a few years ago made a lot of money. Today you don't get rich anymore, but it is still so attractive that, beyond a certain size, it even makes sense to fully finance photovoltaics externally. The grid operator pays off the loan and you use your own green electricity. You just lend your roof for a good cause. It's win, win, win. Or something like that.

In addition, you can switch to electricity marketing at any time. Currently, you would earn more money with that than with the regular remuneration. So there is only a risk if we lose our constitutional state AND at the same time electricity becomes infinitely cheap. In my opinion, one excludes the other.

In advance: Since this will probably turn into some kind of construction diary here: Could one of the mods please remove the addition "Questionable Expert Recommendations" from the thread title? Thanks!

Contract awarded without first creating a work description and fixed cost price.... you either have a lot of trust or you are reckless.

Sure, I tell the construction company "Just do whatever you think, I'll pay anyway."

I think that the planning contract does not necessarily mean that he has already commissioned the complete implementation. Here with us it is currently the case that the planning itself already costs money and the creation of an offer as well. But maybe I misunderstood.

No, you understood correctly, that's how it is.

Aha, something with photovoltaics in winter?

Photovoltaics in winter is not as bad as one might think. The efficiency is better at low temperatures, and on a sunny winter day there is more yield than in the height of summer. In summer you have (pollen) dust and other dirt on it if it doesn’t rain for weeks. That also affects the yield. With a sufficient roof pitch (mine is almost 50°), the snow does not stay on, but slides off quickly. If necessary, you just go up on the roof and help with a broom if it freezes at the top edges of the modules.

Regarding the photovoltaic nonsense from , I won’t say a word now, it really hurts to read. If you have no clue... how was it again? Thanks to for the patience and effort to explain the basics.

We were busy over the weekend and shoveled out almost eight tons of sand from the ground floor. Before that, we of course pulled up the floorboards and, due to the lack of a second container (me, an idiot), first threw everything into the garden. So yesterday I had to go at it again and move all that stuff into the container that was then ordered. If you don’t have it in your head, you have it in your arms :D

The house no longer smells like the previous owner for the first time, but like a construction site, which for me is somehow a special moment. Next weekend we will take care of the garden.

why do you want to remove the screed from the floors? Old screeds are better in terms of vibration and sound insulation than some new insulation materials.

We need the space for thermal insulation against the cold basement (no space in the basement due to 1.93m room height) and for the underfloor heating.
