I have a small array in back of my house, what would be better for a sometimes shaded spot? 2, 200 W 24 volt solar panels wired in parallel or 4, 100 W 12 volt solar panels wired series parallel, a MPPT controller would be used either way. ( I would appropriately size wires and fuse all panels of course ) right now I have just the 2 12 volt panels wired in series (24v) going to a MPPT controller. Or would I be better just to add 2 more 100 w 12 volt panels wired in series (24v) going to a second MPPT controller, charging the same battery bank?
