A high frequency photon from the sun strikes a rock on earth transferring its energy to the rock. At the same time, the rock is radiating away some of its energy as low frequency photons. The result is a steady-state system. Is it right to say that the increase in entropy is the energy of the photon divided by the temperature of the rock?

i would suppose so

I would say it's (energy of the photon - energy radiated by rock)/temperature of the rock.
