... that is almost OK... but in your example a lot depends upon my position relative to the sun... if I lie down and sunbathe I will probably feel cool... but if I stand up in the sun I might feel warm... so if my shadow covers 2m2 on the
ground then I guess I might actually be getting 200 W / m2
from the sun... your
snowy mountain picture illustrates this well because the trees have long shadows.
