“PV klein” and “PV groß” are small and big rooftop solar power plants.
“PV frei” are utility scale (large scale) solar power plants.
as you can see, rooftop and small-scale solar power plants typically are more expensive in generation than large-scale utility power plants.
the only advantage of rooftop/balcony solar is that you don’t have to pay the grid operator to transport the power to you.
annoying
if electricians need to work on the power line, until today they just have to cut off the power supply coming from the big generators. in the future, if homes can feed into the grid, it’s more difficult to ensure that there’s no voltage on the power lines, which makes repair works on them more difficult.
Balkonkraftwerke (balcony solar) + feeding into the grid isn’t ideal IMO because it’s a bit more expensive and it creates problems with the grid.
