Currently I have 2 Renogy 100W panels among another brands. The Renogy is hooked up to its own string with a separate MPPT controller. I was planning to get 2 more of the identical Renogy panels so that I could have 400w on one string. All 4 panels would be connected in series. There's a guy locally selling 2 Renogy 100W panels and I was just about to buy and I noticed the voltages are different.
Picture 1: My current panels.
Renogy RNG-100D-SS. VoC is 20.0V, Vmp is 16.0V, Imp is 6.25A, Isc is 6.45A.
Picture 2: The panels I was going to buy.
Renogy RNG-100D-SS. VoC is 21.6V, Vmp is 17.9V, Imp is 5.72A, Isc is 6.24A.
What's with Renogy? These panels have the exact same model number. Yet the specs differ by as much as 10%.
