12v MPPT and 24v MPPT vs 24v PWM Test
Got a chance to try out comparing amps to the battery using MPPT vs PWM on a 24v battery bank and comparing those with the usual MPPT on 12v with my 230w panel. The bank is four 6s, so it was easy ...

Sounds like fuzzy math to me.
Two 135W panels will produce equal wattage whether they are in parallel or series.

I'm finding some have a higher total wattage when in parallel than when in series. For example, one particular 135w/12v panel has 231w in series, and 250w in parallel. The two 140w panels I happen to own work out to 250w, either way. It's all in the individual specs. I think bfl mentioned this? There are just soooo many variables!
