How do i effectively repair solar panels that have been surged

frenchheman

Hello. I have acquired several free solar panels. I mean alot!!! 400+

I would like to understand exactly how my solar panels work?

From cell to cell voltage, how to measure current and voltage.

If any ohms should go through a diode or not ( i know it should only go one direction, but is there minute ohms possibly in the other direction)?

And is there a way to measure voltage from diode to diode to see were the damage is in the cell loop?

And any relevant info that i could use.

I am prepared to measure and remove bad cells and replacewith new ones and reseal the entire panel

Thanks sincerely
Karl

Here is a good (long) write up on how to assemble DIY panels.

 it may help you understand how to pull them apart for repair, and how to re-assemble.
Beware, the actual PV cells are thin, brittle wafers, and when they crack, become useless.

How power should be per cell on a cs6x-305p 36volt 305watts Canadian solar 6x72 cell?
