Just checking. Parallel or series

I’m sat here in wonderful bright sunshine watching the MT11 repeater for the EPever duoracer mppt controller cycle through its info. It seems to indicate 21.7 v from the panels. Does this mean they have been wired in series? I’ll try to post a little video for perusal at your leisure

21 volts from a solar panel sounds normal. Definitely wired in parallel. The MPPT controller will take that and regulate it to 12 volts nominal, with a corresponding increase in current, compared to the input.
