Photovoltaic system: Costs, saving potential? - Experiences?

: I admit that was a bit abbreviated and striking, but I did write that the feed-in tariff can expire during the year. No one knows exactly when yet. If the cap (52-GW cap) is reached, it doesn’t mean the remuneration stops immediately. There is a transition period of 2 months (I can’t find the link right now). Of course, I would only install a system on the roof once I have a concrete activation date and accordingly know that my electricity will still be remunerated.

That I have to pay VAT here, I indeed forgot to mention. However, it is negligible compared to the income/savings. Since I am subject to VAT, you can also reclaim the VAT on the entire photovoltaic system. This is the reason why the whole tax nonsense is worthwhile. If you don’t want to bother with that, you can just do it under the small business regulation.

What happens if there is no feed-in tariff remains to be seen. But I don’t think you have to give the surplus away....

Before accepting any solar installer’s offer, you should indeed stop by the p-h-o-t-o-v-o-l-t-a-i-c-f-o-r-u-m beforehand...

You would probably get 3-4 cents on the open market, then unfortunately it hardly pays off anymore, except maybe for self-build. However, if politics really fails to continue promoting renewables, even facepalming won't help anymore.

The duration of the feed-in tariff was tied to the cap. But that has now been removed. Basically, there is no longer any basis to let it expire. The problem here is that unfortunately it was only said that the cap is removed, but not what happens with the tariff.

Edit: I have to correct myself, apparently they have reconsidered and are still thinking about what to do with it. What a back and forth...

@Specki: I admit that was a bit abbreviated and catchy, but

No "but"
The thread starter has outed himself as clueless here, so it is not good to write shortened and catchy things.
By the way, you also forgot income tax in your list, which has to be paid on the profit, and also that the form should be insured and reserves should be formed. Usually, a beginner does not know all this at first.

I'm fully with you. A photovoltaic system usually always generates profits and is worthwhile both monetarily and ecologically. But one should not simply omit points.

Yes, the cap has not been lifted yet. At the moment, politics is really fumbling embarrassingly....

One more question about the lid or the elimination of the feed-in tariff.

I spoke with a solar installer today. He said the elimination, if it really happens, only affects system operators >40kWp.

I couldn't find this fact anywhere else either. Have you heard of this before?

No, never heard of it.
As far as I know, EVERYTHING is currently open.
Wait and have some tea. Alternatively, try to kick the politicians in the ass!
