Solar Panel Cable Size

Using the below charts find the current in amps on the left.

Solar panel cable size.

The cable should withstand maxumum current in a always choose cable type that satisfied both conditions. Solar panel wiring size calculator this solar panel wiring size calculator lets you to work out the gauge of wire to safely take the solar dc power from a set of solar panels. The main issue is the wire size needed for the usually fairly long run to the solar panels. Cable wire size needed in mm2 cross sectional area wire diameter in inches.

I will need 6 awg wire. The solar sizing calculator will then be able to tell you the minimum and recommended system size as well as the recommended battery output. Then look straight up to the wire size at the top. This corresponds to awg gauge 8.

12 24 or 48 volts. Use this to determine the right cable for your solar panels be safe and save money. Detailed instructions for using the wire size calculator. Calculated wire diameter in inches or cable wire size in mm2 and rated maximum ampers for power transmission if cables are wired in a bundle or maximum amps for chassis wiring if each wire is routed separately.

Simply stated the higher the voltage the smaller the wire size that is needed to carry the current. This is crucial to building a safe and efficient system to meet your energy needs. For example i want to run a 10 amp load wire 50 with 5 losses or less at 12 volt. We get calculated that we need a copper wire of 0 128 diameter in inches and a recommended maximum current of 29a defined by choosing solar system voltage.

Step 1 the first step is to decide on the voltage for your system.
