I took the guesstimate from this graph (earthobservatory.nasa.gov/ContentFeature/EnergyBalance/images/…) in the article linked in my answer - it might be slightly higher or lower, but +-100W | |

I think you'd be safe to assume a radiation loss way higher than 200W/sqm. That NASA link at the end of the Q states "The energy that Earth receives from sunlight is balanced by an equal amount of energy radiating into space." | |
