Fuse or Not Fuse?

[BillN]

Solar Array 4 Panels 100W (2 Series 2 Parallel) Voc = 22.8, Isc = 5.78
Maximum Series Fuse Rating = 10 A

Calculated 45.6V & 11.56A I added .25% to Volts for temp changes
Total Calculated 58V & 11.56A

Some Panels have Maximum Series Fuse Rating = 15

Will I need to fuse the Solar Array?

single string or 2P don't need fuses/breakers.
