It's important to select wires that are properly sized for the currents and voltages in your solar energy system.
Wires that are too small will cause significant voltage drops, and therefore a significant solar energy loss, as well as possible overheating that may cause a fire.
You can use our Solar Wire Size Calculator to select the proper wire for your needs.
Below you will find a detailed explanation on how to use the calculator, and how it selects the proper wire for the different sections of solar power systems.
We also offer amazon link of viable wires base on your result when possible.
