What size cable to use for a 12v solar panel. Different solar systems need different wire sizes. Even different parts of a solar system may need different sizes. Solar power usually needs a 12 gauge AWG wire. But as the size may differ depending on resistance and flow, you need to determine the amps to know which size you need.
In this case, Wire Amp Rating ≥ 3 × 10A*1.25*1.25. It needs to be no smaller than 46.88A. If the distance between the solar panel array and the charge controller is 13ft, 10 gauge wires would be the right size to use by referring to the "Electrical cable size chart amps" chart.
Solar systems use two distinct cable types: ⚠️ Critical: Never use standard THWN wire for DC solar circuits. It lacks UV resistance and proper outdoor ratings required by NEC 690.31. Use only solar-rated PV wire or USE-2 cable for panel connections. 1. System Current Calculate maximum current your wire must carry:
