Customer ServiceTwo 100W solar panels in series. First, we must calculate the maximum amount of current going through the wire. Imax = Isc * 1.5623 (safety factor) = 6.2A * 1.5623 = 9.7A. Let''s say the length of the wires is 30ft to the charge controller. We now have to use a voltage drop calculator to figure out which wire we need. We will enter the
Customer ServiceAfter learning about solar wire size calculator, here is a guide on how to calculate solar wire size: Determine the voltage drop: Voltage drop refers to the loss of voltage during the cable’s current flow. It is recommended to size the wire to achieve a 2 or 3% drop at the typical load.
To size the wires between your solar panels and solar charge controller correctly, you’ll need to make sure that the ampacity of each wire is at least 1.25 greater than the maximum current going through the wire, and that the total voltage drop between your solar panels and solar charge controller does not exceed 3%.
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. The formula P=E*I says that the wattage/power P is equal to the voltage E times the current I in a circuit.
The total watts produced by the solar system is one of the most critical factors determining solar wire gauge size. The more watts, the more amps produced, and the thicker the wire size you’ll need.

Maximum Current (Amps) = Short-circuit Current (Amps) x 1.25 For example, if you’re trying to size the wire needed to connect a string of solar panels to the solar charge controller, and the short-circuit current of the string is 9 amps, the maximum current is calculated as such:
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.
