Solar Cable By the Roll

Twin-Core Solar Cable in 100m Rolls

When a project calls for more than a few metres of PV wiring, a full roll is more practical than repeated short lengths. This collection offers 100m rolls of twin-core DC solar cable in two sizes: 4mm² twin 1000V PV1-F and 6mm² twin 1500V IEC 62930. Both are purpose-built for connecting solar panels to charge controllers and inverters. They suit installers, fleet fit-out workshops and owners wiring larger off-grid systems.

Twin-core construction runs the positive and negative conductors together in one cable. This simplifies routing through roof entries, conduit and cable trays compared with running two single cores. Buying by the roll also means one consistent cable specification across every run in the system or across multiple installs.

Applications for Bulk Solar Cable

A 100m roll of solar cable is well suited to:

• Caravan, RV and 4WD fit-outs: workshops completing repeat solar installs can stock one specification for every vehicle.
• Off-grid homes and tiny homes: longer array-to-controller runs, where extra cross-section helps reduce voltage drop.
• Marine and boat installs: neat twin-core runs from deck or bimini-mounted panels back to the charge controller.
• Commercial and industrial projects: ground-mount or roof arrays where the 1500V IEC 62930 rating supports higher-voltage string configurations.
• Inventory for electricians and installers: you can cut lengths to suit each job and avoid ordering short pieces every time.

How to Choose Between 4mm² and 6mm² Solar Cable

The right cable depends on system voltage, current and run length:

• 4mm² twin 1000V PV1-F: suits typical caravan, RV and small off-grid arrays with moderate current and shorter cable runs. It is lighter and easier to route through tight spaces.
• 6mm² twin 1500V IEC 62930: the larger conductor area lowers resistance, so it is the stronger choice for longer runs, higher array current, or systems where minimising voltage drop is a priority. The 1500V rating also gives more headroom for higher-voltage series strings.

Always confirm that the cable's voltage rating exceeds your array's maximum open-circuit voltage (Voc), including cold-weather increases. To work out the correct cross-section for your current and distance, use our DC cable sizing and system wiring calculator before you order.

If you only need a short length for a single panel or a repair, our solar cable by the metre range lets you buy exactly what you need. You can also browse the full solar cables range for other options.

Stock Up on Solar-Rated Cable

A 100m roll gives you one consistent, solar-rated specification for every job. It also reduces waste from mismatched offcuts and keeps your next install moving. Choose 4mm² for everyday mobile and small off-grid arrays, or 6mm² 1500V for longer, higher-current runs. Order your roll today and have the right PV cable on hand when the next project starts.
