solar panels stopped working

Postby lewharve » Sat May 13, 2017 1:38 pm

I am getting no energy from both solar panels , they are 3 years old and all of a sudden they stopped working.
I check all the inside connection and no power.
is there a fuse on the panels
what can cause them to fail

don't worry
I checked at the plug and it was 18 v on the solar plane
so I guess new plugs
cheaper than new panels
but why both at the same time

Either just to confuse things or perhaps because they both have the same lifespan. I always try to remember to look for the simplest explanation though it seems almost human nature to expect the worse case. ;)

Could be that you have panels rigged in series, without bypassing diodes. Failure of one -in this case could be the downstream one, but may be either- means you get a failure in the whole array. Reconnect in parallel as a test, and you'll find out
