FAQs 6

How do I use the wire size calculator?

To use the Wire Size Calculator, just follow these 4 simple steps: Enter Solar Panel output voltage. Usually 12, 24, or 48 volts. Enter the total Amps that your Solar Panels will produce all together. Enter the distance in feet from your Solar Panels to your Battery Bank / Charge Controller.

How do I calculate a solar panel wire size?

Just like water in a pipe, the smaller the pipe, the less water that can pass through it. To use the Wire Size Calculator, just follow these 4 simple steps: Enter Solar Panel output voltage. Usually 12, 24, or 48 volts. Enter the total Amps that your Solar Panels will produce all together.

How does solar wire sizing work?

By using this solar wire sizing calculator you will notice that the higher solar system voltage translates into: longer cable for the same voltage drop if you keep the same gauge used for lower solar system voltage. Please use the update button if the calculated data are not refreshed automatically by the solar cable size calculator.

How do I calculate a solar panel output voltage?

Enter Solar Panel output voltage. Usually 12, 24, or 48 volts. Enter the total Amps that your Solar Panels will produce all together. Enter the distance in feet from your Solar Panels to your Battery Bank / Charge Controller. Click on 'Calculate' to see the size wire required in AWG (American Wire Gauge).

How do I choose a solar panel?

Step 1 - The first step is to decide on the voltage for your system: 12, 24, or 48 volts. The main issue is the wire size needed for the (usually) fairly long run to the Solar Panels. Simply stated, the higher the voltage, the smaller the wire size that is needed to carry the current.

How many volts does a solar panel produce?

Usually 12, 24, or 48 volts. Enter the total Amps that your Solar Panels will produce all together. Enter the distance in feet from your Solar Panels to your Battery Bank / Charge Controller. Click on 'Calculate' to see the size wire required in AWG (American Wire Gauge). Enter the output voltage of your Solar Panels.
