I have to applaud you taking this on, it's an uphill battle trying to use metric yourself with the assumption no one uses it, let along getting someone else to use it.
I would imagine the US might have a hard time selling panels in other countries if the hard dimensions are in feet. I recently bough a iPad mount for a vehicle, it attaches to the seat track, I had not given it a dimensional thought until I could not find an allen wrench to fit the allen bolt. I had to call and ask them what they were using, turns out it was 3/16th inches, I have a number of Cycles and cars and none use fractional inch anything. So I was at a loss as to what I could do? I basically told the guy they were out of touch with reality, Standard is metric, not inches as he stated. I also wrote them a letter. http://www.ram-mount.com/Products/AppleMounts/tabid/1647/Default.aspx#/ Mike Payne On 27/04/2012, at 18:45 , Pierre Abbat wrote: > I'm dealing with two contractors for my house: one who drills wells and one > who designs and installs solar electric systems.
