Copper or Aluminum: Which Should You Choose?
Neither conductor material is universally better for every project.
Aluminum alloy may be preferred when:
- Long cable routes make conductor weight important
- Raw-material cost is a major project consideration
- Larger cable sizes can be accommodated
- Approved aluminum-compatible terminals are available
- The project specification permits aluminum conductors
Copper may be preferred when:
- Installation space is limited
- Smaller conductor diameter is required
- Standard PV connectors are designed for copper
- Termination simplicity is a priority
- The project specification or local rules require copper
The final comparison should consider installed cost rather than conductor price alone. Cable size, support spacing, connectors, lugs, labor, voltage loss and approval requirements can all affect total project cost.

Customization Options
Project-based options can include:
- Conductor size
- Black, red or customized sheath color
- Cable marking
- Meter marking
- Coil, reel or drum length
- Export packaging
- Project labels
- Pre-cut cable lengths
- Technical document package
Customization remains subject to minimum order quantity, production review and applicable certification requirements.
