Re: [RE-wrenches] Sharp modules

[Kent Osterberg]

Kirpal, 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.

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....
