100w panel slowly dying

[Destructor]

First off I'm new to this site and thank you so much for accepting me I hope that the knowledge in here can answer some questions and I have acquired quite a bit myself I'm hoping I can help out as well. I have a bunch of 100 watt panels and I noticed one of them doesn't seem to be putting out as much as the rest. Can a panel slowly die?
Shouldn't it just completely crap out?

They all slowly die a little each year. If this one is not keeping up with the others by some larger amount then it likely has something wrong with it.

I bought them all at the same time. Last time I checked them they were all pushing approximately 4 amps. Then within 2 weeks 1 has dropped to 1 and a half and the rest are still at 4. All with the same sun exposure. I even swapped wires around to make sure that wasn't the case.

how are you measuring this one PV module?

My solar controller has full digital readout. It tells me volts and amps, battery input and draw. I just unplug all but one panel and get full info.

Likely something damaged it, or moisture has slowly crept inside and is killing it. not really any way to fix them

How old is it? If it's within the warranty period, get it replaced.

3 years I think? I never thought of that. I'll look into it thanks.
