Has anyone calculated this?
In terms of potential data loss, more smaller disks will be more reliable and there is less risk of a problem while replacing a failed disk. In terms of cost, the 1/2 size disk may be of the same quality/performance grade but cost 1/2 as much as the bleeding-edge capacity disk. Power consumption has more to do with the drive's targeted application than its raw capacity. Solaris supports power-management so you could allow it to spin down the drives when they are not being used, with the limitation that it might take 30 seconds before data is available if you have been away for a while. If the drives are spun down, zfs's access behavior will cause all of them to spin up at once.
