Cable length question

I am planning an installation with 12 panels (3KWatt) in a 4*3 arrangement with a Vmp of 92.1 volts and an Imp of 32.6 amps. Using 16mm2 cable I determine that on a 50M length my voltage drop will be  3.3429 OR 3.6297% and the power dissipation will be 108.9 Watts. Based on my research I feel confident that the voltage drop to the MPPT controller is acceptable but I have no idea on whether the 108 watts is OK or not.

Can anyone give me some feedback on how serious or not 108 watts of dissipated power is.
