“Damaging equipment” is just nonsense. I’ve got an off-grid solar system. When the battery is fully charged the solar panels simply stops producing. It has potential (voltage) but no current until you draw power. Just like a battery is full of energy but it just sits there until you draw power from it.
All solar systems could have smart switches to intelligently disconnect from the grid as needed, some inverter already do this automatically. So it’s not a technical problem. It’s a political problem.
This can cause degradation of the PN junction on the panel shortening life. The plans I’ve seen all have a resistive heater some place to dump the excess when full. Smart equipment does help mitigate most issues like moving the resistance point on the panel for lower efficiency when signaled to do so but less is not the same as none.

Concentrated solar and wind are a bit different though?
