In reply to Emilysaladfingers:
Torbryan is in the shade until mid to late morning and then is in the sun until evening. On really hot, sunny summers days the rock temperature can be too warm for harder red pointing, particularly with the polish, until 9pm when conditions can be perfect.
I don't know about van spots. But don't stay overnight or even just park in the layby on the left just beyond the entry gate to Torbryan. That's a turning circle for the very sharp right hand turn to Torbryan hamlet (see the hard copy guidebooks and UKC crag log book etc).
