A flat surface, perpendicular to the solar rays at the earth's solar
distance intercepts roughly 2.00 cal/cm^2/min (the X15 aircraft actually
measured 1.95 at an altitude of 82 km).  Of course there is less energy
that reaches the surface if one includes an atmosphere with clouds (this
reduces the figure by about 30%) and when considering a sphere, the
energy intensity/cm^2 varies of course by latitude.

Opinions are my own
