Wire and cable do not always have to be run in conduit if they are not in a location where they will be exposed to damage, like an attic or under a PV module. If they are not placed in conduit, they still must be properly secured and supported appropriately. The electrical code for the location will specify the minimum distance between supports, although the appropriate distance between supports should ultimately be determined based upon what will offer the most protection from accidental contact or damage from friction. Cables and wires should be snug against the surface they are being run against rather than drooping or dangling, although they should not be so tight that they are being significantly strained between supports. It is important to offer additional support near junction boxes as strain placed near a connection can lead to its failure.
