Damaged Panel question

Postby Rollers123 » Thu Sep 24, 2009 3:26 pm

I have a flexible solar panel that has been damaged. Is there any risk of short circuit if the blue material has a white mark where the cease damage occurred.

I have some old Canon panels purchased about 15 years ago which sustained damage that sounds similar to yours when hit by something in a storm quite a few years ago. They are quite flexible considering they are in frames, but not flexible panels as such. The area of damage seems to have spread a little, but I didnt notice any reduction in output up until I took them out of use (replaced by more efficient larger 24V panels).

Depending on where and how large the damage it, its main effect would probably be limted to taking out a cell or 2. Short circuiting a single cell would usually just mean a slightly reduced panel voltage. Shading a single cell would cause a greater reduction in output.
