I got my extra set of panels and after talking with the dealer about the swapping history (only one job they have done so far) I chose to wait until they had a few swaps under their belt. Has anyone swapped theirs yet? If so, did you have a tech do it or did you do it yourself? I remember seeing something on the timing being 2-4 hours but I hear it's difficult to keep from breaking the clips so I don't want to attempt it myself.
