I have 6 LG Neon 2 360W Panels and I want to connect 2 strings of 3 panels. I have purchased 8metres of 4mm2 Twin Core Solar Cable and 10metres of 6mm2 Twin Solar Cable. I have just spoken to a friend and he said why did you get twin core, you should have got single. Can anyone tell me the difference and how you would connect my system with twin core solar cables?
Any Help will be much Appreciated
