Also, PV wires come in different voltage ratings, like 600v, 1kv, and 2kv, whereas USE-2 wires are typically rated at up to 600v. Plus, the temperature rating of PV wire is generally higher than that of USE-2 wire.
Choosing the right wire sizes in your Solar PV system is essential for both performance and safety reasons. If the wires are undersized, there will be a significant voltage drop in the wires resulting in substantial power loss. Also, if the wires are undersized, there is a risk that the wires may heat up to the point in which a fire may result.
