Hello all
I have a Lg neon 2 black solar panel.
I bought it second hand knowing it was faulty - quite cheap.
The seller told me it was down on power by about a third.
There is a plastic box on the back with some diodes in it.
There are 3 panels in series connected in series with diodes.
With no load on a bit of a dull day two of the 3 cells were a very similar 12v and one was only 7v.
My question is this.
When panels go faulty do they go high internal resistance?
I could leave it as it is or I could just have the two good panels in series and dump the faulty 7v panel.
To test it with load scientifically I would have to buy a small collection of high power resistors which I don't really want to do.
I could even separate off the 7v faulty array and use it for a separate system, put in a boost and use it to keep the starter battery topped up?
Thanks for reading my first post!
