This isn't really true, though? The ISS does it with radiators that are ~1/2 the area of its solar panels, and both should scale linearly with power?

I don't pretend to understand the thermodynamics of all of this to do an actual calculation, but note that the ISS spends half its time in the shadow of the earth, which these satellites would not do.

You would put these in polar orbits so they are always facing the Sun. Basically the longitude would follow the Sun (or the terminator line, whichever you prefer), and the latitude would oscillate from 90°N to 90°S and back every 24 hours.
