Hey guys, most of you are going to think this is a little OTT, but please indulge me.
I obviously want to get the most out of my solar system, especially with the naff weather we have over her (UK), so I want every bit of my system to be as efficient as it can be.
So, wire resistance. Binky said that the wires on the back of the panels (not looked) will be 4mm², and all the wire I'm bringing down through the house will be 6mm². Now the resistance of 4mm² is more than double that of 6mm², so I obviously want all 6mm² in the system.
In light of this, I'm thinking of chopping the wires off the panels as close to the panel as I can get and replacing it with 6mm².
Am I to assume that this will reduce the resistance, as the length of a wire will also increase the resistance, so the shorter the 4mm² the better? Or will the 4mm² set the resistance for the whole line, like having a resister in the line?
Sorry, I've tried to read up on this, but can't find an answer to this.
Be kind with your replies.
