I would prefer if you could provide sources. One typical trap I see people fall into is mistaking physical flow for trading.
With Germany being in the center of Europe, it always has a large amount of energy exchanged with France, thats a physical necessity, basically due to "transiting" through the german grid to other countries.
But even in 2020, Imports and Exports with France leveled out with Germany exporting a bit more.
The low prices are not set by solar, as you probably know, subsidized renewables are always sold for 0, they can't change their pricing. But fossil plants (especially lignite and nuclear) drop their prices as they are not able to completely turn off or reduce below a certain amount of power.

If you have a better source, let me know.
