You could also say its AWS. They also should have the experience, but mistakes happen

Vienna made one to an aquarium (Haus des Meeres https://en.m.wikipedia.org/wiki/Haus_des_Meeres)

Balcony solars are not able to back feed since they need the grid to synchronize, if you want one that is able to work in "island mode" you still need approval from the grid provider/one that isnt connected with the schuko connector.

They have enough energy, but they automatically turn off once the grid goes down because they need the grid to synchronize. Balcony solar panels are not able to work in "island mode", so no lineman is at risk.

Luckily I'm not in school anymore xD

But thx for correcting me, edited my post, should be correct now :)

You can get a 800Wp (max allowed Wp for a balcony solar) kit in austria for around 500€, germany is currently limited to 600Wp so it should be about the same price or cheaper. And you just need to plug them into a schuko outlet, so most people should be able to do it themselve.

Edit: Fixed units

Its not that bad, its just all 5 seconds and not 2 seconds so no problem there! /s

I'm not only not buying a tesla because I'm not a fan of musk but also because I don't have the money ;)
