Using This Solar
Wire Calculator

Enter length in Meters.

Enter Amperage.

Enter voltage drop required
Example: 1,2,3,4,5,6.

Try different voltage drops,
and compare with the wire
size you have to work with.

This solar panel wire
calculator is intended for
approximate guidance.

You also have to
determine if wire size will
carry the amperage
