To determine solar array wire size, consider panel wattage, voltage, distance, and voltage drop limits. For example, a 300W, 24V panel 30 feet away may require 12 AWG wire. Always consult local codes and a professional for precise sizing. How do you calculate the …
The size of wire for solar panels depends on the current and voltage of your solar system, as well as the distance. Commonly used wire sizes are 10 AWG, 12 AWG, or larger, but the specific size should be determined based on your system’s requirements. (Note: The passage does not directly answer the question about the size wire solar panels need, but it does provide the necessary context and information to understand how to determine the correct wire size.)
To calculate the Wire Size (in AWG), use this formula: Wire Size (AWG) = (2 x Distance (in feet) x Current (in amps)) / Voltage Drop. The gauge of wire you should use for solar panels depends on the current and voltage of your solar system, as well as the distance the wire needs to cover.
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.
For a 400W solar panel system, you can use 10 AWG wire for relatively short distances (less than 50 feet). For longer distances, consider using thicker wire, such as 8 AWG.
For example: 10 solar panels rated at 5 amps at 12 volts. You want a 24 volt system so you wire 2 panels in series to make 24 volts. You do this 5 times. The 5 pairs will be wired in parallel where the current adds to give you 5 sets times 5 amps per set equals 25 amps. Enter the 25 as the maximum amps your wires need to carry.
Once these parameters are established, you can calculate the suitability of your planned cable length in feet (ft) using the gathered information. You can also use American Wire Gauge (AWG) to help pick the correct solar cable size. The lower value of AWG means larger wire, better current flow, and less voltage drop.
