DC wiring losses are mainly caused by the ohmic resistance of the cabling that interconnects PV devices and strings, although losses can also occur in connections and fuses..
Designers strive to keep DC cable losses to less than 1% of the peak power output of the entire solar panel system..
NREL’s study “Performance Parameters for Grid-Connected Systems” is a widely cited source of loss factors, and they suggest a 2% loss for DC wiring..
Cumulative DC system losses for an installed residential solar system typically hover around 10%..
The wire gauge (AWG) should be selected for an ohmic loss of 1.5% or less. The formula to calculate the current are: DC side : I = P / U or I = U / R AC side: I= P / (√3 U cos φ) or I=U / (R cos φ) [pdf]
