The advantage of panels in series is an earlier start to the charging day, a later end to charging day, and more likelihood of power generation when there are poor or cloudy conditions.
My system maxes out at 17 amps @ 12v output (nominal) and even in rain I get 4 amps at solar noon. My own system is series/parallel with a nominal input voltage of 33.
interesting. currently in heavy rain the max I've produced is 22w, didn't check the amps.
I knew a few of the 24v/48v benefits as in efficiency, thinner cables(id keep the same old fat cable why not) but thats about it.
so I have
1x renogy 12v 150w mono panel
1x mighty max 12v 150w mono panel
5x 100w renogy 12v mono panels
3x 50w 12v renogy mono panels
because of the odd numbers I can't do a perfect 24 or 48v setup with what I have correct? best case is leaving out 1x 100w, and 1x 50w panel. right? thanks!
