Enter the distance in feet from your solar panels to your battery bank charge controller.

Gauge of wire for small solar panel.

These are the two basic wire types. Solar sizing calculator allows you to calculate your energy consumption and requirements to help you decide on your solar panel requirements. Use this to determine the right cable for your solar panels be safe and save money. You would need at least 4 gauge wire awg to move 18 amps 30 feet with a minimum voltage drop of 3 or less an acceptable loss.

Besides this solar cable gauge calculator is designed to provide estimates for wire gauge size to determine your need for cables. I will need 6 awg wire. This allows up to 30 amps of current to flow from a single panel. Enter solar panel output voltage.

Then look straight up to the wire size at the top. Enter the total amps that your solar panels will produce all together. If it has a single metal wire core it s a single stranded conductor and if it has a multiple wire core it s a multi stranded conductor. Igreely solar panel extension cable 10 feet 10awg 6mm solar extension cable with female and male connector solar panel adapter 10ft red 10ft black.

If you can t find the exact numbers choose either a larger gauge wire smaller number or select a distance longer than your actual distance. For example i want to run a 10 amp load wire 50 with 5 losses or less at 12 volt. Commercial solar pv panels over 50 watts or so use 10 gauge awg wires. If multiple panels are combined in parallel then a three to eight awg combiner wire set is generally needed to safely transfer the power to a charge controller or gti.

Click on calculate to see the size wire required in awg american wire gauge. Usually 12 24 or 48 volts. Follow this to the left until you see the one way length of wire you need in feet. Using the below charts find the current in amps on the left.
