And we come back to my original point. Residential roof installation is the most expensive way to install solar power. Utility scale solar is easily haf the cost of residential.
I can't wrap my head around what off-grid balcony solar even means. Balcony solar is meant for apartment dwellers. Or detached home/townhome owners who don't want to spend on a rooftop install. You aren't installing balcony solar to go fully off-grid.
It's limited to 800W in Germany and 1200W in Utah. It isn't about to replace utility-scale generation anytime soon.
Those limits are just arbitrary regulations. It's easy to install 10x that on a residential roof.

Balcony solar is installed on a unit-by-unit basis. It isn't 800W per building; it's potentially up to 800W for each unit in an apartment.

Balcony solar can still satisfy a significant portion of a household's demand.
That only applies if you connect it to the grid in each of those places, I believe.
