I don't think you understand how this works. People voluntarily do this. No one is forced to. Public power providers exist and work. Balcony solar is added and helps save some cost because you don't buy those 800W from the public utility provider.

People are forced to do it by high household electricity prices which are the direct result of the government policy failure.

In my childhood everyone (like your parents, your neighbors, all the ordinary people) were growing potatoes. Highly decentralized and fully voluntary sustainable food production, sounds like a dream. This happened of course because the state-run economy created food shortages.

I can easily afford my power bill. I still have a Balkonkraftwerk.

Its fun to do, it makes sense and was easy.

And your potato example is also shit. Being able to buffer a higly complex and easily disruptable supply chain for things you need to survive is smart not stupid.

Nobody is forced. It makes economic sense, so people do it. It’s how the economy is supposed to work.

[alexey-salmin]

Exactly, like growing potatoes made economic sense to my parents' generation.

Economic sense is largely defined by the economic policy set by the government. No one puts balcony solar in France, somehow their economic sense is different.

France has changed permitting laws to allow small-scale solar, i.e.: balcony solar, the difference is that the nominal output is much lower (350W vs 800W for Germany) which, by policy, makes it less attractive.

So it isn't that France economic policies have made installing balcony solar unattractive, it's the permitting policies which are blocking people from installing more.

You have it inverted, pun intended.

Germany could allow 2000W, or 4000W, instead of only 800W, but you seem to be missing Alexey's point.

Germany has very high electricity prices, even higher than the US (see https://worldpopulationreview.com/country-rankings/cost-of-e...), and this is due to policy failures in Germany. That's what makes these balcony systems so appealing.

I'm not sure that the outcome of having a lot of decentralized solar generation is a bad outcome.

[adrianN]

The 800W are to prevent fires. You can’t just arbitrarily raise those limits.

[piva00]

No, I didn't miss the point, I know they were talking about electricity prices. My counterpoint is that France is not seeing balcony solar not only because electricity prices are lower but due to policies which limit it.

It's a both-things can be true, even though France has also been getting more issues with electricity generation from its nuclear fleet caused by droughts, and high temperatures in their cooling water supply.
