Distance between solar panels. The choice of wire gauge is influenced by the spacing between solar panels. Thicker wires are needed to transmit signals over greater distances without experiencing voltage drops, which is necessary for system safety and reliability. Say you''re putting solar panels on your roof, and they''re 3 feet wide each.
The size of your solar panel determines what cables should be used. Insulation provides protection for the wires, and they are color coded for easy identification (blue no charge, red positive charge).
Solar panels come with about a metre of cable so not normally long enough to reach your battery bank. MC4 connectors are rated to cope with the current and weather proof so you can extend the cable. For wiring 2 panels in series, you need 1 single pair of MC4 cable connectors. For wiring 2 panels in parallel, you need 1 pair of 2 pronged MC4 Y-branch …
