Solar panel glue bonded cell to glass

Hi I'm a newbie here so please allow my ignorance.
I have just been given two 100 watt panels that has shattered glass. I have not tested them yet but i was hoping to dismantle it to construct a new panel with new glass. The problem I see is that the cell is bonded to the glass but the glas does pick of but leaves some glass behind. My ? is there a way to remove the glass from the panel maybe by dissaolving the glue some how.
Thank you
Jackal

I've got a panel like that so I bought a sheet of perspex and stuck it on using silicon sealant. It needs mechanical fixing as well or possibly the use of No Nails or a similar glue. I'll be giving it a try.

Sounds Like a plan. Im going to test the panel today maybe with my tongue.

I very much doubt that you will be able to remove the cells from an existing PV module, for re-use, without breaking them.
If the module works, then I would cover with another sheet of glass or plastic as suggested above.
The useful life will probably be very limited though, since you wont be able to achieve a perfect seal, and the cells are said to degrade if exposed to water, not just rain, but traces of water vapour in the air.

Your English isn't 100% perfect, Jackal. Don't you mean you're going to
taste the panel today?

Do It Yourself 12 Volt Solar Power by Michel Daniek, ISBN 978 1 85623 039 1, page 106:
- Your should still get 70% of original power
- Uncovered it will be destroyed by water and humidity
Glue a new layer of thick glass (5/6mm) to the aluminium frame using polyurethane glue (not silicon). Sikaflex recommended. Make sure it's totally waterproof. He suggests holding the glass with metal brackets in case glue fails. Sikaflex is serious stuff, my solar panel is glued to my van roof with it, and it's still there after thousands of miles!
