LCoE is a partial metric at best, it tells you nothing about how useful the energy is produced. For comparison a nuclear bomb produces an LCoE of about ~30cents/kwh but that doesnt make it a good energy source to power a grid with.
When you are adding intermittent sources to a most despatchable grid, sure LCoE tells you most of what you need to know, as displaced more expensive sources just throttle down slightly. But once you get into significant fractions of energy (~1/3 or more) just having expected joules created / cost to build is not a particularly useful metric for an intermittent power generator.
Solar and wind are the cheapest sources of energy today.
Flat-area solar is much cheaper than rooftop solar (source 1, source 2)
“PV utility scale” and “PV frei” means flat-area solar; “PV klein” and “PV groß” means rooftop solar (small/large).
