Solar Cable

Solar cable is purpose-built for connecting photovoltaic panels to inverters and other solar system components in residential, commercial, and industrial installations. Unlike standard electrical cable, solar cable is specifically engineered to withstand harsh UV exposure, extreme temperature fluctuations, and outdoor environmental conditions over 25+ year system lifespans.

Our solar power cable range features UV-resistant sheathing rated for direct sunlight exposure, with options in both single core and twin core configurations. Available in 4mm² and 6mm² conductor sizes to accommodate different system amperage requirements, these DC-rated cables ensure reliable power transmission from solar arrays to inverters while maintaining compliance with Australian photovoltaic installation standards.

Licensed electricians and solar installers choose our solar cable for new installations, system expansions, and replacement projects requiring durable, standards-compliant PV wiring solutions. The double-sheathed twin core options simplify installation by combining positive and negative conductors in a single cable run, reducing labor time on larger commercial solar projects.

All solar cables are supplied in convenient 100-meter rolls, providing sufficient length for typical residential rooftop installations while minimizing waste. Competitive wholesale pricing supports project profitability whether you’re installing a single residential system or managing multiple commercial solar deployments across Australia.

FAQs

What’s the difference between 4mm² and 6mm² solar cable?

The 6mm² solar cable handles higher current loads and is typically used for longer cable runs or larger solar arrays where voltage drop becomes a concern. The 4mm² cable suits most residential installations with shorter distances between panels and inverters. Your specific system amperage and cable run length determine the appropriate size.

Can I use standard electrical cable for solar installations instead of solar cable?

No. Standard electrical cable lacks the UV resistance and temperature ratings required for outdoor photovoltaic applications. Solar cable features specialized insulation designed to withstand continuous sun exposure and temperature extremes without degrading, ensuring system safety and longevity over decades of operation.

What does “twin core” or “double sheathed” solar cable mean?

Twin core solar cable contains both positive and negative conductors within a single outer sheath, functioning like two separate cables bundled together. This simplifies installation by reducing the number of individual cable runs needed between panels and inverters, particularly beneficial for commercial projects with multiple string configurations.

How much solar cable do I need for a typical residential installation?

Requirements vary based on roof layout and inverter location, but most residential systems need 30–80 meters of cable. The 100-meter rolls provide adequate length for standard installations with material left over for future expansions or repairs. Calculate exact requirements by measuring the distance from your furthest panel to the inverter location and multiplying by your number of strings.

Is this solar cable compliant with Australian standards?

Yes. Our solar power cable meets Australian photovoltaic installation requirements for DC-rated cabling. The UV-resistant sheathing and temperature ratings ensure compliance when installed according to manufacturer specifications and relevant Australian electrical standards.
