A lot of people are probably in the situation of buying 400W here and 600W there, or trying to build expandable systems. Does anyone know a list of the most common important PV parameters, especially Voc, Vmp, and Imp?
If you're mixing and matching smaller solar panels, are there particular stats that will make finding well-matching ones easier? Any weird voltages to avoid because that one manufacturer is the only one that uses it?
I get that the most common answer is probably "buy another SCC for the new ones", but that's not the best if you need to overpanel for winter use, have a mobile system with an extra array at home, are moving to a camper with more roof space, switching from 12 to 24V using the same SCC, etc.
I ended up buying 23.7Voc panels that only fit 3 to a string on my Vic 100/30 after temp correction. No regrets, because they were cheap and I probably won't need more for a while, but should I have actively been looking out for e.g. 22.5Voc ones? How would you even go about searching for specific Vocs?
It's sort of odd that there's not too much discussion of optimal panel stats online. Most people seem to buy what they buy and rig the system accommodate the gear, rather than the reverse.
