    Im only metering input with the watts up meter so voltage varies.
    So all though it put in "10A" it may have been from 13v up to 20v..
    So by reading the watts input it doesnt matter the voltage or amperage as its the sum of both..
    But yea, both days have been similar.
    Only just reached a peak of 100w input threw the day, so still got a lot of headroom..

    Yeah, I know what you mean.
    I have 4 x 25 watt semi flexible panels feeding a Tracer MPPT reg and that outperforms my prev 120 watt (2 x 60's) folding setup plus is 1/2 the size folded up and about 1/4 the weight.
    Ended up selling the 120 watt about a year ago as I wasn't using it.
    Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.

    Yeah quantity wins every time , the 600 watt I had on the van kept three batteries going no matter what the weather and most of the time it was only charging two anyway .
    I've heard 250 watt of solar minimum per 100 amp of battery covers you on overcast days but only just and depending on usage .

    Well atm the van had 200w pannel and 120ah battery.
    So adding my 120w gets me around the 2.5-1 ratio..
    I did read 2-1 is good.. but more is better as you say..
    Best bit is both are 22v pannels.. so ive set it up to run in parallel so itll be 14A @ 22v..

    Yep, if all panels are the same Voc (open circuit volts) that idea will work tickety boo
