It is being sent into the general electrical network of the house/flat, where it lightens the base load. There is a maximum of 800W that you are allowed to feed into your home network. Anything bigger is subject to different rules and approval by the electrical service provider.
800W aren’t a lot, but it can half the cost of your washing machine run, make your fridge power free and let a PC idel or a NAS run. These balcony solar generators usually make back their costs within 5-8 years if you calculate what you’d otherwise pay for the electricuty.
The AfD isn’t only here since yesterday. They have grown (read:festered) over the last 10 years of stagnant, conservative politics. The “middle” parties SPD and CDU have, instead of creating a clear separation, become closer and closer to the AfD and taken up their talking points. Mainly, but not only regarding migration politics as well as social security.
They had 10 (well, maybe 8) years to outgovern the AfD, stabilise and strengthen democracy and remove the basis for the social Angst that leads to hate of migrants. They have failed at that and still cling to the same narrative. And they are still making it worse and “outgoverning” the AfD is in this case, just taking over their “solutions”.
Edit: I totally forgot the racism. Germany is institutionally racist, but noone wants to talk about it, it’s a non-issue in the minds of many. So there is nothing to rectify. If you don’t ask PoC.
