Somewhere between minimal and none. Satellite operators pretty much own
their 'slots' in practice so they keep their slots clean - retired
satellites are put in a lower junkyard orbit.

But this raises an interesting question - what slots are these space
solar satellites going to occupy? Most of the useful slots (i.e. the
ones visible from industrialized nations) are already filled.
