Hmm...  On these BP panels that would only give about 1mm depth. Don't
know if that would be satisfactory.


Cheers, J/.

Well, 9 - 10 years later the panel is still working. BTW it is a BP.

You are missing nothing. If no cell is brooken, the panel will still produce
its full voltage. Actually, the power drop can be very small.
The problem with the broken glass is that moisture can enter the cells and
it can oxidize (ruin) the electrical contacts.

 Thanks to all who replied!
   I went to a local "Hobby shop" and the Casting resin you speak of is
REALLY expensive!!!!  (Like to the tune of $0.00 for a few ounces!)  After
talking to the guys there, they suggested I try a hardware store. .. .
SOOOoooo . . . Off to Lowes I went . . . They don't carry it, but suggested
I try fiberglass resin.  They said it is basically the same thing, and it
still dries clear.
   Anyone have any experience with this stuff?  Think it will work?

I'd check the properties of it to see what they mean by clear,
compared to the special wide-bandwidth low-iron tempered glasses used
for solar panels.  Or not, since whatever you get is free (plus or
minus the cost of the resin, and assuming your time is worth nothing).

Aso, see if you can find out what it's lifetime is in outdoor
applications in direct sunlight without any protective paints or
gel-coats.
