Edit: Be aware that some people try to post misinformation here, such as that such plants are not safe in the case of a power failure (untrue), or that they are not economical (untrue, their advantage is that they have very low installation costs).
By the way: One reason why electricity from the grid is relatively expensive in Germany is that private consumers pay much higher prices than large, power-hungry companies. Effectively, consumers are subsidizing companies, which in turn can often profit from very low prices for power from solar generation, because companies can buy from exchange markets at spot prices, but private persons can’t.
Balcony solar plants shift that tilted balance back a bit.
Next by the way: Access to these special prices for companies depends on the total amount of electricity used. Which adds a reverse-incentive: Under some circustamces it is cheaper to waste electricity in order to keep access to cheaper prices than to use less electricity. Because if you use less then you have to pay normal prices.

And after all this, they still piss and moan about “prohibitively high energy prices”.
Good old Umverteilung, love it
Next best thing: German electric engineers to the rescue. Without regulations.
Black Panther MEME with VDE/ISO “We don’t do that here”
With the next Revision of the ISO/VDE it can only get worse for this theme, because of overregulation.
Except for my lab. In whichever, I do whatever I want to do.
Which seemingly is a collective fortitude.
Regulations were very careful in the beginning, but now it is that basically anyone can plug in a system like this and register it.
To note, there were some technical challenges, of course the plug needs to be safe when it is not plugged in, and the system switches off when the power fails, which is also for safety - these are not autonomous or “island” systems though of course, solar can be used for that.
There are currently talks about tightening these regulations, to the point where it is no longer feasible to use these kind of systems :(
So how good is it? I’m pondering a 400W panel but I have 2 balconies, one for the morning sun, one from around 11h…
