These 20% will still make you dependent on foreign country.
For example Germany was dependent on Russian gas (before year 2022), which they later swapped for dependency on US LNG. In addition, Germany is dependent on China for PV panels.

There is merit to putting one's energy policy on autopilot by doing the opposite of whatever Berlin is up to.

This is gas brain thinking.
Panels aren't burned to make electricity. If literally everyone stops selling you panels (nearly impossible) you continue generating electricity the old way. Nothing bad happens. The panels you already have continue working.
Other countries make panels too. India has a glut right now.
