Solar Panel Voc-MPPT?
Wondering if there is any relationship between measured Voc and MPPT performance with a 24v panel. My 12v panel has a Voc rating of 21.9 and Isc of 8.2, but I often see 8.2ish when Voc is only 20....

I see you learned nothing about the previous discussion. You were told by the Rogue guy your logic was wrong. You're using exactly the same logic again! I'm not going to explain your errors. I have no desires to enlighten you. You have lost my respect.
If you keep stalking me with your nonsense, you will be the second person that's on ignore.

Sorry, Ken, I misread your example from the very beginning. If the resistance stays constant, then yes, power is directly proportional to the square of the voltage drop across it.
I was assuming your analogy was related to the power loss in a wire, which is seldom related to applied voltage, but rather to the resistance/size of the wire or the current through it, which causes the voltage drop across it.
Doesn't seem to me that I was told I was wrong...
EDIT: Hijack over and I apologize for derailing the thread, but I was trying to correct an assertion that was wrong...
