pro-list04

Solar photovoltaic (PV) cables for renewable energy installations. Halogen-free XLPE/XLPO insulated cables rated DC 1000V-1500V with excellent UV, ozone, and weather resistance. Compliant with IEC 62930, EN 50618, and TÜV standards for 25-year PV system design life.

Solar cables are available in a wide variety of constructions, manufactured in accordance with diverse global standards and adopting tailored material formulations. When selecting cables for specific projects, it is necessary to take into account performance requirements, laying conditions and complex environmental factors, and guarantee full compliance with relevant cable specifications, industrial codes and local regulations.

Solar Cable Manufacturer

Manufactured compliant with multiple British and international standards, our photovoltaic cables satisfy the EN50618 standard under harmonised classification H1Z2Z2-K. Suited for conventional ground-mount solar farms and rooftop photovoltaic projects, they serve as interconnection links for PV arrays and power generation systems. This heavy-duty outdoor cable range is engineered to endure extreme ambient conditions and UV light ageing.

Our supply scope covers aluminium solar cables and low-voltage DC combiner cables for module-to-inverter/transformer power routing, plus cabling solutions for full grid interconnection, applicable to both private distribution networks and contestable grid connection assets.

Solar Cable TUV approved

As TUV certified cables, the EN50618 solar cable range have undergone a rigorous manufacturing and testing audit programme to deliver a quality cable with an anticipated lifespan of circa 25 years. This is consistent with the quality standards we set for all of our products.

In order to ensure the optimal performance of your solar systems, we also supply solar cable accessories, including our connectors and specialist crimping tools to allow fast and error free installations.

FAQ

Answers To Your Most Common Questions

Where is solar cable used?

Solar cables are used as interconnect cables for solar panels and photovoltaic arrays in a solar power grid. Solar power cables can also be used in underground entrances and service terminal connections. Be sure to check cables for compatibility with grounded or ungrounded systems. In general, USE-2 Wire may only be used with grounded circuits. Photovoltaic Wire (PV Wire) can be used in both grounded and ungrounded solar installations.

What is solar cable?

PV solar cables are TÜV-certified EN50618 DC wiring built for solar arrays. With UV-resistant XLPE insulation, they endure harsh outdoor conditions for around 25 years, linking solar panels, inverters and grid infrastructure for rooftop and ground solar projects.

How to choose the right solar cable?

Choose TÜV-approved EN50618 H1Z2Z2-K certified cables;
Select proper wire gauge based on your system’s DC current to minimise energy loss;
Pick double-insulated, weather-resistant grades for outdoor exposure;
Choose copper or aluminium conductors according to project scale and budget;
Pair cables with matching connectors and crimp tools for reliable, fast installation;
Select products with rigorous quality testing and a 25-year expected service lifespan.

How to use solar cable?

Before installing solar cables, confirm their certified EN50618 specifications and correct cross-section size matching your PV system’s current, and prepare matching PV connectors and professional crimping tools. When laying wiring, route cables via UV-resistant trays/conduits with proper slack for thermal expansion, separate DC and AC lines, strip insulation carefully without damaging conductors, crimp terminals tightly and fully lock sealed connectors to link panels, combiners and inverters. Protect outdoor cables from UV, corrosion and sharp edges, avoid over-bending, and conduct post-installation electrical and visual checks; always cut power to panels before live wiring work and carry out yearly maintenance to inspect for ageing or loose connections.

What are the common types of solar cables?

The most common solar cables are TÜV-certified EN50618 copper PV cables for rooftop panel wiring and cost-saving aluminium solar cables for large-scale solar farm long-distance transmission, alongside dedicated low-voltage DC combiner cables and grid connection AC cables.
