Shadowing also means connecting as many panels in parallel as possible, then the power reduction is lower. Facades facing the winter sun also make sense. They produce less overall, but during times of increased demand. Unfortunately, my wife vetoes my project to install another 20kWp "winter system" on the slope side next to the driveway.

Huh? That's not true at all, exactly what is demanded is reality: a grid operator cannot refuse connection and is obliged to purchase the produced surpluses. Meters running backwards are terrifying from a billing perspective, this is solved with bidirectional meters.

Priority regulations for renewable energy... Basically, renewable energies have priority as points out. For large installations, the supplier is authorized to temporarily shut them down - as possibly means. The old gear wind turbines make terrible noises and suffer from wear and tear. One of the reasons behind this is the Renewable Energy Act itself. It grants priority to renewable energy; non-renewables compete behind them with their bids for the additionally needed electricity. Since nuclear and coal are cheaper than gas, they get priority. Unfortunately, nuclear and coal – unlike gas power plants – are very slow to respond. If too much energy from renewables is fed in too quickly, nuclear and coal plants regulate down too slowly; if too little energy from renewables suddenly comes in, these plants regulate up too slowly (this was also a problem in mid-August, when steel and aluminum plants were temporarily disconnected from the grid to ensure supply). In the transition period toward 100% renewables, better integration of a flexible, controllable technology such as the partly state-of-the-art gas power plants would be sensible. This would be an immediate, very effective stabilization measure. For this, the remuneration mechanism of the Renewable Energy Act levy to the power plant operators would also have to be changed, since switching on gas power plants costs more than just the increased production price for the additional amount. I recommend watching one of Joul’s videos on the usual video channel about this.

Hmm, who is still supposed to be able to afford to install a photovoltaic system? Phew, and I wouldn’t want a wind turbine nearby either… no idea if there have been any technical improvements, but the ones standing by our [Erdbeerfeld] are super annoying when it comes to noise.

Phew, so electricity from the socket is really something dangerous. Better leave it. I'd rather have a nice view. It's also much cheaper!

Edit: Back to serious for a moment: do you hear those things in your bedroom or only when picking strawberries?
And on the topic of "affording photovoltaics": Currently, you can even make money by installing photovoltaics. In the worst case, it costs about as much as electricity.

That is not a serious question, is it?
The photovoltaic system brings economic benefits. Everyone can use that.
The question remains about the liquidity burden – there are many good solutions for that, which work for most homeowners.

Wind turbines can indeed cause noise and strobe effects. However, I have the impression that we tend to judge wind turbines more strictly than airports and highways.
