[RE-wrenches] Sharp modules

[Mark Frye]

Kirpal,
 
I am not sure about the caulk or lack of it. Nor am I sure about the
variance in size.
 
However, I have been working with the NT-240's and have to admit that a nice
rubber mallet is now one of my standard tools.
 
If the module is laying down out of square, a firm tap on the corner of the
frame brings it into square and on we go.

Happy Friday.....so i was installing some sharp 240w modules today and
noticed again that the modules do not have any sealant between the glass and
the aluminum frame.....I have noticed this on the 216's and the 80's as
well.....the glass and cells all seem to float independent of the
frame......all other modules we have used have a sealant sometimes too much
in the groove surrounding the glass inside of the frame.....
As we were installing the modules we noticed significant 1/4"+ of variance
in frame dimensions from one end of module to other, with mid clamps holding
the modules on one side you could pull the frame and it would move
independently of the glass......
Does this manufacturing method have some advantages that i am not aware of?
It just seemed odd that the glass and silicone cells and backing encapsulant
can all move around without being held firmly in place......we are new to
using the sharp modules and was interested to see if anyone else had any
insight into this design....
Cheers.
