    Those look like a resister not blocking diod are black and silver ¥

    Possibly when the panels were built someone installed them opposing each other or backwards completely. Either way the manufacture should fix them not you.Sure it's a easy fix but NOT acceptable , if they tested there panels before shipment it would have been caught. So simple to test the diode for correct installation with a meter ,and if it was in backwards they could have hacked up the wire with a knife again and fixed it with some more crapy solider job. So no sales for them from me.

  5. The sound was great and almost no wind noise so rock on buddy. You could just put in blocking diode on the line it self I am going to put in two on my wind turbines I got the really big diodes for that. Yes you are correct they could be hooked up but they would also drain your batteries. So after you replace the diodes you are ready for action.

  6. base on the output it's a good panel, not unusual for a new panel that has defective diode, anyways what I think is if that was connected to a controller, no need to install the diodes
