Construction costs are currently skyrocketing

Speaking of funding, is there currently none for photovoltaics (if delivery + installation in 2023)?

I have photovoltaic + storage because I sat down and did the math - amortization 8 years (2020) now we are at 6 years due to saving more expensive electricity. I have my VW-e-Up! because I sat down and did the math - balancing the additional cost compared to a conventional purchase 5 years. Back then diesel (1.15€) now I am probably at 2-3 years. Since diesel costs 2.30€, I stopped doing the math. Overall: 10% ideology 90% because it pays off (2020) Today? Such a photovoltaic + storage system could already be very expensive and only paid off in 15 years with luck. But no one can see into the future, if 60ct/kWh become normal, then the expensive photovoltaic from 2022 is already paid off in 10 years. Because this here: says the nice man from the Check Portal. regards

I can gladly say it again. If 60 cents become normal, things go downhill. And with everything. No civil servant with a lifetime appointment can feel safe anymore.

I can say it again if you like. When 60 cents becomes normal, things go downhill. And with everything. No civil servant with lifetime tenure will feel safe anymore.

And it will go downhill. The fat years are over.
Even Habeck says that.

Photovoltaics - not worth it since payback is over 15 years? - gone -> Is it worth it at 60ct/kWh?
Why always 5% more for everyone? Why not simply 200€ more for everyone, those who earn little will be happy - The man in a suit and limousine may not be so happy, but he probably has enough to live on...
...

And does life get worse because of that? I say no
And I'm only talking about the top 50% in Germany here - the bottom 50% already live like this anyway.

Speaking of subsidies, is there currently none for photovoltaics (if delivery + installation in 2023)?

In 2023, the VAT on photovoltaics is supposed to be completely eliminated. It's probably not a huge deal, but it brings the break-even point a few weeks closer again. And you save yourself the VAT prepayment ;)
Otherwise, I wouldn't expect any further photovoltaic subsidies. The signs rather point to a mandate; the BW Greens would ideally like to introduce this for existing buildings now as well (for roof renovations it already is, so we're talking about a real existing building mandate), so far the CDU is against it. But constant dripping...
By the way, this is also a point that should not be completely ignored in the discussion. If something is going to become mandatory anyway, it's better to plan for it right away than to wait until everyone is really obligated.

In 2023, the VAT on photovoltaic systems is to be completely eliminated. ...

It is probably even the case (checked today specifically) that even existing systems for which input tax has already been deducted and refunded can now be reclassified as "hobby activity" without consequences of partial repayment (however, this apparently only applies to a total of up to 30 kWp of all systems owned by one owner).

This is not quite correct. The VAT still exists, but at a zero rate. Since photovoltaic system operators are no longer burdened with VAT when purchasing the system, they no longer have to forgo the small business regulation in order to have the input tax amounts reimbursed. This relieves them of bureaucratic effort. However, to my knowledge, this only applies to new systems. For existing systems, only the income tax exemption applies. Those who currently opt for VAT are still bound by it until they switch to the small business regulation. Oh yes, the 70% curtailment rule has basically also been abolished.
