Perhaps of interest is the Victron Energy "MPPT Calculator Excel sheet" which can be found and downloaded by scrolling to the bottom of This Victron Webpage
IMO a wonderful tool
, it allows you to load the specs for your PV panels of choice
then quickly run various scenarios for parallel / series schemes, system voltage, ambient temperature, etc, etc and see all sorts of useful data including voltage and current yield with various Victron MPPT controllers. It correctly handles all the arithmetic drudgery behind the evaluation scenarios.
While you can't load it with non-Victron controller
specs you can often correlate those to other brands / models if that's your inclination.
Just for your consideration, Have Fun!
