‘If 1.5m Germans have them there must be something in it’: how balcony solar is taking off

it's not actually that bad, unless you live next to a gen 1, or maybe gen 2 plant. Unless you're next to one of like, three existing operational RBMK plants.
By the time you needed to evacuate from that area due to a nuclear disaster, you would be well informed, and probably gone already. Even if you didn't the radiation exposure is likely to be incredibly minimal. Probably under the regulated limits.

not very much, especially during the winter, the best way to optimize panel production is by pointing it towards the sun most effectively, the farther north, or south, of the equator the less effective it is, the less directly it points towards the sun in general, the less power you make.
It might still produce a decent amount of power overall, through a reasonable period of time, but it's probably WELL below what you could be making with an optimized install, especially one with solar tracking, granted some solar power is still better than no solar power, so you do get tradeoffs at the end of the day.
as another commenter said, there are solar power calculators out there, if you're looking for rough figures, use them.

Agreed. I maybe a radical DC home evangelist but yeah AC has its place still and it being THE standard for home appliances is a good example of the powers of scale.
So far for my home usage I'm standardizing on 48vdc because that is the last multiple of 12 before you go above OSHAs low voltage regs.
From there I really want to standardize further on the power delivery spec, because I just love the idea of smart grid for my home. I can then have dispered batteries in my home for either the primary benefits of that device is portable but doesn't always need to be (laptop, power tool batteries, little robot thing, car, etc) or as a way to reduce some crazy limited time power draw (like servers starting up, oven running for an hour a day, etc).
From there maybe just Microadapter for a few standard circuits so the outlets work the same.

Germany's energy transition is a masterclass in contradictions. Dismantling nuclear plants—clean, reliable, and efficient—only to lean on Russian gas and coal is not just shortsighted but self-sabotaging. The Energiewende, while ambitious, has exposed Germany to geopolitical vulnerabilities and grid instability. Renewable expansion is commendable but insufficient without robust infrastructure and energy storage.
The reliance on balcony solar panels and rooftop systems reeks of performative sustainability. These micro-solutions barely scratch the surface of Germany's energy needs yet are paraded as revolutionary. Meanwhile, bureaucratic inertia delays large-scale renewable projects.
The nuclear phase-out, driven by political expediency rather than pragmatism, left an energy vacuum filled by fossil fuels. A true green transition demands realism: embrace nuclear, bolster renewables, and stop romanticizing half-measures.

This me me lol. Thank you

any form of collective project requires organization, which conveniently is not required for an individual project that can be as impulsive and unsafe as the individual wants.

That's 4' 11" - I had no idea Germans were so short.

French electricity leaves the chat in summer when their plants need to be shut down because the rivers are too warm or don't carry enough water in the first place. And that's nothing to say what they will do in the next decade years when a good portion of their reactors should be commissioned out.

Not that expensive either. And that's already included in the energy price. Also volume is magnitudes smaller than used solar panels.

It's going to be hard to justify production costs, but in places that subsidize it: it makes perfect sense to scale up solar wherever possible.

During WW2, there were multiple

There is something in it - they are making solar panels with chemicals that makes energy trans

Grids work on economies of scale. The bigger the better. Ask anyone who lives on an isolated island for their power bill. That's why it was such a big deal when the Baltics switched from the Russian grid to the EU one.
Bigger grid = more intertia&redundancy = less likelihood of failure, more options, lower costs.
Electricity isn't like chicken eggs. Transporting it is for all intents and purposes free. The network is expensive, but whether your house is pulling 1 A or 5 A is a non-difference to your utility. So to think local generation is "better" is a complete fallacy. Unless your house is fully disconnected from the network (not "net zero", disconnected) then it's not helping to generate power locally. Like someone else said, it's actually way more expensive per kWh than grid-scale solar.
Now this would all be a "you" problem, except the big problem with microgeneration is that current tech is "dumb". It's either pushing power on the network, or sometimes tripping if the voltage goes above 250V or so. Which actually happens in rich neighborhoods on very sunny days where everyone is pushing power.
What this means for the operators is that on very sunny days, they cannot do anything but account for the extra residential solar power. Which might mean they have to very quickly spin up or down alternative power generators which were not meant for this. Or they might be dealing with complex issues with current flowing the other way than designed and large voltage fluctuations on specific parts of the network that don't have the necessary infrastructure to "dump" that extra solar somewhere else.The end result is that, counter-intuitively, microgeneration is one of the many failures of the neoliberal electricity market. It's more expensive and more disruptive for society than if those solar cells had been put to use in grid-scale solar production. They only end up where they are through political mismanagement and misaligned incentives (e.g. net metering which does not account for negative externalities).

I'm sure this is a good thing, but considering the vast majority of Germans haven't figured out screens on windows I'm not sure the appeal to authority in the title has the desired effect.

I wasn't being sarcastic. I appreciate that my local energy provider is green and stable

The actual problem are electricity prices rising higher and that shortens to time to reach the equilibrium between the investetment
