slightly different solar qx
Am looking at solar on a small class A. I currently have 3 group 27 batteries (rv/marine) for the house. (prior owners had just installed 2 new, and I had one from a trolling motor setup) they will...

When I got into solar we were spending summers off-grid out in the open at a "seasonal" site we had. PWM and an "aimed" 130w panel got us the AH needed.
I did my solar mostly ground- mounted in a tilting/twirling contraption I made. jimindenver got me onto the low cost Eco-Worthy 20 amp MPPT with a 250ish watt panel as a combo. Worked great. I now have a Tracer MPPT with another panel on the TC's roof.
I was surprised I didn't get as many amps as I thought I would would with the MPPT, but I measured along the whole path and learned where the various losses were. Learned how to do that here mostly ISTR. Once I understood how it really works I was happy with the amps
We still go back there but not for such long stretches and don't have our own site, so now the panels are on the roof. Still get bags of AH per day, hardly ever need the gen in the good weather May to Oct.
Take solar for granted now, lost the urge to measure everything as when a newbie.
