Just 10 years ago, landlords could ban you from putting solar cells on your balcony because it makes their building look "messy". Now Germany is really pushing forward to let everybody put solar modules on their balcony with these new laws. How is legalization of balcony solar cells in your country? Is setting up solar modules on your balcony easy or difficult law-wise?

Translated by Google:

In the future, private individuals will be able to operate mini solar systems as balcony power plants without complicated registration

This is the coolest part. As I understand it you'll be able to export 500w to the grid without requiring approval of your provider. The new units just plug into the wall and back feed power into your house to reduce your bill.

Depending on how the law is written, I can imagine people putting a battery between the solar and inverter so they could capture more energy and export the maximum 500w all day & night

The important thing on backfeeding is that utility workers will need to isolate at more points before working, otherwise they will get injured by backfeeding/battery systems if they run on infrastructure they are working on.

Should not be an issue. The inverters that feed into the grid need to follow the phase and frequency of the grid. If the grid is down, there is nothing to follow and it will not feed any power into the grid.
