I have not read through all the comments so if this has been covered ignore me.
If you have an MPPT controller you can series panels up to the rated volts, my Renogy is limited to 100 volts. Since you have so many panels you could spilt them in half and then parallel them together. So say you have 8 panels you can wire 2 sets of 4 in series giving you 48+ volts, then parallel the 2 sets together. This will drop your voltage but your amps being put out by the controller will be the same or possibly better. I spoke with one of the Renogy techs about this. Main key is dont run voltage over the rated controller. They have one controller I think that is rated to take up to 150 volts.
PS: If you are going to parallel panels you have to have equal number of panels in each set.
