[RE-wrenches] Fwd: Magic PV cell

[Jerry Shafer]

Wrenches
To be sure you will need an IR Camera but yes it does happen one cell is
failing and has become an energy consumer instead of a supplier, you will
see a discolored cell and to the touch it will be noticeably hotter than
the surrounding cells, I have seen this with several manufactures. I
attached a pic of a module that was too hot to put your hand on on the
failed cell. It may de difficult to get manufacturer assistance  without a
IV curve test on each module. You also should look at the back sheet as it
may be discolored or even burned.
