What is the main advantage of Aluminum Alloy cable over Copper?

The primary advantage is cost efficiency. Aluminum alloy cables can reduce the cable budget by 30-50% compared to copper. Additionally, they are significantly lighter (approx. 50% the weight of copper), reducing transportation and structural load costs.

Quick Comparison of Aluminum and Tinned Copper Solar Cable
Feature	Aluminum Solar Cable	Tinned Copper Solar Cable
Electrical Conductivity	Lower (larger size required)	Higher
Weight	Very light	Heavier
Installation Cost	Lower	Higher
Corrosion Resistance	Good (installation-sensitive)	Excellent
Thermal Expansion	Higher	Lower
Material Cost	Low	High

What standards apply to Aluminum Alloy Solar Cables?

Since EN 50618 only applies to copper, Aluminum Alloy cables must be certified to TUV 2PfG 2642 (Europe/International) or UL 4703 (North America). They must also meet IEC 62930 requirements for PV cables.



Does Aluminum Alloy suffer from "Creep" or "Cold Flow"?

Standard aluminum does, but AA-8000 series alloy does not. The specific alloying elements (like Iron) strengthen the crystal structure, giving it creep resistance comparable to copper, ensuring that terminals do not loosen under thermal cycling.
