Now if you wire 2 of those panels in parallel you will have 2 x the Imp or 15.9amps but the Voc = 44.8volts.
If you wire 2 sets of 2 panels in parallel you will have 4 panels with a Vmp of ~ 70.4volts and and Imp ~ 15.9amps at peak production.
The wire from the 4 panels will need to be sized to handle 15.9amps x 1.25 ~ 20 amps as long as it isn't too long and drops that 70.4v more than 2%. If it does the wire will need to be bigger.
