Comment(by dylan):

 Here is the code used to produce the example images. Note that the beam
 and diffuse radiance maps created by r.sun are clearly incorrect when
 slope and aspect maps are not specified. The output looks correct when
 slope and aspect are specified. The beam and diffuse radiance maps are
 attached as: "beam_rad.015.jpg" / "diff_rad.015.jpg" (only elevation
 given), and "sa_beam_rad.015.jpg" / "sa_diff_rad.015.jpg" (slope and
 aspect given). The DEM used can be found here:
