Ed, I am the OP, and I am again showing my ignorance here -- why would a 120 wat portable panel (like mine) be immune to a voltage drop? Is the drop worse for more powerful solar panels?
The more I read the posts on this forum, the more I wish I had taken some electrical engineering courses in college, rather than a bunch of soft social sciences!! ;)
Your 120 Watt panel can only output about 6 Amps max, ( under optimum conditions. ) voltage drop in the circuit is directly proportional to your current.... and to the resistance of your connecting circuit. You have not stated what your connectong circuit is. May I assume you are going to use 10 gage wire and it won't exceed 30 feet? The resistance of that wire and a single connector plug is so minimal for your 120 W panel that it isn't worth fretting over. Use the connector you want. You will be fine.
