[RE-wrenches] recover broken modules

[Joel Davidson]

Jeff,

You can put another glass front on top of the module to protect the cells and wiring to get a few more years use from the module. My customer got 3 years of use from a broken module in extreme Alaska weather. Other customers had similar luck.

1. Clean with low pressure dry air to remove loose glass and dirt. Be careful with flying glass and avoid damaging cells, interconnects, and bus wires.
2. Inspect and repair backsheet tears.
3. Test to ensure Voc and Isc are within specifications.
4. Wipe front edge of frame with clean, dry cotton cloth.
5. Apply non-acid silicone RTV on front edge of frame.
6. Apply glass cover module and let silicone seal cure for at least 24 hours.

Good luck.

  Over the past few years we have had our share of modules damaged in shipment or in handling on our end that were never installed but had broken glazing.  As you know, when these things go they usually look like a car windshield, with the vinyl backing holding all the broken small glass pieces together.  Seems like a shame to trash, is there anyone out there with a way to re-glaze a new module with broken glazing.  

  Any chance you could just place a new glass glazing over the broken glass and seal?  Or some way to remove the glass pieces without damaging the module cells and inter-connect foil connections being held in place by the backing. Seems like a business opportunity,
