Solar sail effect is going to be dwarfed by regular atmospheric drag in low earth orbit. At perfect right angles the radiation pressure on the panels is 4.5 micro-Pascals. Meanwhile, in low orbit there’s enough residual atmosphere to generate a dynamic pressure (for drag) of 5 milli-Pascals, give or take (and strongly depending on the space weather).

So atmospheric drag is around 1000 times more than photon pressure. And the drag is big enough to be noticeable over weeks and months, requiring regular boosts to stay in orbit.
