I don't think so (at least not without modifying the code), but I would be interested in the same functionality. > May be I can use r.los for selecting the reliefs that actually cast a shadow > on the area of interest? That would be ok for the beam radiation, but you might affect the diffuse and reflective radiation calculations that way. ?
