Moniek Vesseur,
        I believe the GRASS contributed shell script <> will
solve your problems. The following is the definition from g.manual: - Creates a shaded relief map based on current
     resolution settings and sun altitude and azimuth values
     entered by the user.
     (GRASS Shell Script)

Have a great day:)
