Frequently Asked Questions

QWhat is UL4703 standard?

A:UL 4703 is the industry standard developed by Underwriters Laboratories (UL) for Photovoltaic (PV) Wire. It specifically covers single-conductor, insulated, and jacketed wires designed for use in solar energy systems. Because solar installations are exposed to extreme environmental conditions, UL 4703 ensures that the wiring can withstand long-term exposure to sunlight, moisture, and varying temperatures.
