I've got a PV array attached to my standing seam metal roof directly above my bed about 24" from my head when I'm sleeping and although we do hear some expansion/contraction noises it's not a problem. Every once in a while we'll hear a loud noise but I think that's more from my timber frame shifting/drying than the array on the roof. I'm sure others' experiences will vary.
