The absorbed energy is the solar flux times the area times the absorbtivity times the cosine of the incidence angle. The solar flux is 1418 W/m2 on average around earth, but it depends on the distance from the sun and other factors. The emitted energy is proportional to the area and the surface temperature to the fourth power.
