Pv voltage drop

With a 3% voltage drop on pwm using a panel vmp of 17.4. 20 foot on 8 gauge gives me 16.87 volts compared to a panel with 18.9 vmp on 70 foot run about 10% drop gives me 17 volts according to calculator voltage drop.net. If with pwm the battery regulates voltage and any thing above that is just lost would a 3% drop on a 18.9 panel give me more amps or watts compared to a 10% drop?
