Thanks to Everyone for your prompt responses! Much appreciated. I will take the panels into the sun today and use a volt meter to verify that the MC4 connector with the red ring is positive.
The OP must have got sun-stroke and zapped himself as well, or we would have heard back by now how that went. :)
LOL, no sun stroke. I got a chance to test one of my three Renogy panels, and as expected by my many helpful friends on this forum, the pigtail with the red band is in fact, the positive lead. As is wont to happen, life then intervened and I didn't get a chance to test the other two panels. Most likely the polarity is the same on those as the first panel, but just to be thorough, I will test the other two panels tomorrow and report back.
