Even in the peak of nuclear electricity production in the year 2001, coal was dominant source electricity in German grid. (Data for 2001, Nuclear 171 TWh, Coal 293 TWh).
Power grid is not and newer was a one-way system, all the AC power lines, transformers don't care for the direction of the current. It's only the amount of current passing through each power lines, transformers that's important.
The side effect of many electric customers installing PV panels and reducing their demand from grid is that the fuel costs of on-demand power plants decrease, but the fixed costs of on-demand power plants (installation, maintenance) stay the same. These fixed costs have to be recouped in the smaller amount of electricity sold by on-demand power plants, therefor per MWh prices from on-demand power plants will increase for electric grid customer.
For most electric customers it's not possible to disconnect from electric grid and rely just on PV panels and batteries.
Germany is not major transit country for electricity. According to data from 2019 electricity interconnection level for Germany was only 10% .
Building of large capacity and long power lines is expensive, therefor many big industrial electric consumers were build near power plants or power plants were build near major industrial customers.

Germany is projected to have import capacity equal to less than 15% of their domestic electricity generation by 2030.
