I think that it shouldn't be much but I wanted to get a ballpark numerical figure.
We've installed a 2kW solar power unit at our home, which is installed on our rooftop. To convert the DC current into AC current, there's an inverter at the Ground floor. We can take the wires to the ground around in two different ways.
The second way is about 6m longer than the first. My question is: will this 6m additional wiring cause a significant loss of final output? Is there a formula that I can use to arrive at a numerical figure?
What is the loss (in terms of final output) per metre of DC wiring, as opposed to AC wiring? I have no idea about what the resistance ratings and other properties of the wire is (if that is important to determine an answer to this question). Is there anyway we could arrive at an approximate figure?
