Are you thinking that the valleys are past the end of the solar tube, so
that the tube is not over head but to one side only?

Yes; in addition to being a lifelong buff of space research, I'm also

such peaks however typically make up a rather small portion of the mtn's
bulk, and the overall slope of the mountain from tip to base has to be
overcome in order to cast a shadow onto a valley floor under vertical
sunlight.
