Solar Panel Efficiency?

[Irish Rover]

just note what the victron app reports at between 1pm -2pm that's the peak right now.

Yeah. Our plan was to be up and running for that time today but there was a delay getting MC4 connectors. We'll see tomorrow. We opted for parallel because there's a short mast just aft of the panels with an anchor light, radar reflector and small flag which casts a shadow on one or other panel at different times.
Thanks again to you and the other contributors for your help and advice.
I'll update the thread when I have more information but I may have patchy Internet for the next few days.

We were away for a few days anchoring out at night but the panels/batteries haven't got a serious workout because we've been motoring a lot as well. The voltage on the batteries drops to 12.4 - 12.5 when the airfryer, kettle etc are working but shoots back up again as soon as they switch off. At the moment I'm very satisfied with how they're performing but I'll be keeping a close eye on them in the coming weeks.
