mdasb,
You are looking at electrical consumption, which is power measured in Watts. The total wattage of your system is the electrical consumption regardless of the voltage.
Here is how it works:
Power (watts) = Voltage (volts) x Current (amperes)
100 W = 24 V X Current (I) –> I = 100 W / 24 V = 4.17A
100 W = 12 V X Current (I) –> I = 100 w / 12 V = 8.33A
The point is that you will be consuming the same amount of power on either the 12V or the 24V system. So to reduce your consumption, reduce the total wattage.
