The Sharp modules have a U-shaped rubber seal between the glass and
frame. It's not visible until you or your freight company breaks the
glass out of one. Since it isn't an adhesive sealant, it does allow the
frame to move independently from the glass a little. I've been
concerned that water will enter between the glass and frame, freeze,
and bow the frames. I think silicon sealant between the glass and frame
makes a more water tight seal.<br>

type="cite">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.....<br>
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......<br>
Does this manufacturing method have some advantages that i am not aware
of?<br>
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....<br>
Cheers.<br clear="all">
