Correction to my last post: While the left mounting screws should
be 7.5 mm from the left side, I think the right mounting screws need
to be a multiple of 5.08 mm away from the left screws. If you used
my suggested measurements for the module and left a tolerance of .34
mm, this should presumably be subtracted from the right side
distance, meaning that the screws should be 4.1 mm (7.5 - 3.4) from
the right side.
The only panels I have yet made were 8hp with single mounting holes,
so I am making a lot of untested assumptions here. Somebody with
more knowledge please help.
