"WebSolar irradiance is 1000 W/m 2 at the surface of the moon and the earth. The reflectivity of the moon is about A = 10%. The solid angle of subtended by the moon in the sky is the same as that subtended by the sun ϵ moon = 6.8 × 10 − 5 Sr. I say this because during an eclipse they appear to the same size so it's probably quite a good assumption.
