What Are Solar Cables?

Solar cables are specialised electrical cables designed for use in photovoltaic (PV) systems. They connect solar panels to the inverter and other key system components, handling high DC voltages while maintaining optimal power transmission. Unlike standard electrical wiring, solar cables are built to resist:

  • UV radiation and extreme sunlight exposure
  • Temperature fluctuations ranging from -40°C to +90°C
  • Moisture, ozone, and chemical corrosion
  • Mechanical stress, abrasion, and bending

Their robust design ensures consistent performance and safety in both indoor and outdoor environments.

Key Features of Solar Cables:
  • UV & Weather Resistant: Designed for outdoor use, solar cables can withstand prolonged sunlight exposure, rain, and extreme temperature conditions without degrading.
  • Flexible & Easy to Install: Built with high-quality copper conductors and flexible insulation for easy routing around panels, rooftops, and mounting structures.
  • Double Insulation: Provides extra protection against mechanical damage, moisture, and electrical faults, often using XLPO (cross-linked polyolefin) for superior durability.
  • High Voltage & Temperature Ratings: Supports DC voltages up to 1500V and can operate in temperatures from -40°C to +90°C, with short-circuit tolerance up to 120°C.
  • Low Smoke, Halogen-Free, Flame Retardant: Enhances safety by reducing toxic emissions in the event of a fire.
  • International Certifications: Complies with global standards such as TÃœV, IEC 62930, and EN 50618, ensuring reliability and safety.
Technical Specifications:
  • Conductor: Tinned or bare copper for excellent conductivity and corrosion resistance
  • Insulation Material: XLPO or equivalent UV-resistant, flame-retardant compounds
  • Voltage Rating: 600/1000V AC or up to 1500V DC
  • Temperature Range: -40°C to +90°C (operational), with short-circuit resistance up to 120°C
  • Core Sizes: Common sizes include 4mm², 6mm², and 10mm², depending on system requirements
  • Sheath Colour: Typically black or red for polarity identification (positive/negative connections)
Applications of Solar Cables:
  • Residential Solar Systems: Connecting solar panels to inverters, charge controllers, and batteries.
  • Commercial Rooftop Installations: Ideal for complex PV systems in office buildings, factories, and shopping centres.
  • Solar Farms & Utility-Scale Projects: Handles large-scale energy transmission with high durability over long distances.
  • Off-Grid Solar Systems: Suitable for remote solar setups, including cabins, boats, and RVs.
  • Floating Solar Farms: Resistant to moisture and corrosion, perfect for solar panels installed on water bodies.
Benefits of High-Quality Solar Cables:
  • Efficient Power Transmission: Low resistance ensures minimal energy loss, even over long distances.
  • Long-Lasting Durability: Resistant to UV radiation, extreme temperatures, and environmental wear and tear.
  • Enhanced Safety: Double-insulated, flame-retardant, and halogen-free for maximum protection in case of faults.
  • Flexible & Easy Installation: Simplifies cable management in tight or complex spaces.
  • Cost-Effective: Reduces maintenance and replacement costs due to superior material quality and extended lifespan.
Why Certified Solar Cables Matter:

Using non-certified cables in a solar installation can lead to:

  • Energy inefficiencies due to high resistance
  • Overheating, which increases fire risk
  • Premature cable failure from UV degradation and thermal stress

Our solar cables are rigorously tested and certified for:

  • UV and weather resistance
  • Thermal and mechanical durability
  • High voltage performance and safety
Choosing the Right Solar Cable:

When selecting solar cables, consider the following:

  1. Voltage Rating: Ensure the cable supports your system’s DC voltage (commonly up to 1500V DC).
  2. Cross-Section Size (Cable Thickness): Depends on the current load and distance from panels to the inverter. Common sizes include 4mm², 6mm², and 10mm².
  3. Environmental Conditions: Choose cables with high UV, moisture, and temperature resistance for outdoor installations.
  4. Certifications: Look for internationally recognized certifications like TÃœV, IEC 62930, and EN 50618.
Common Solar Cable Sizes:
  • 4mm²: Ideal for small residential systems with short cable runs.
  • 6mm²: Suitable for medium to large solar systems with moderate cable lengths.
  • 10mm²: Designed for utility-scale projects or long-distance cable runs between panels and inverters.
Why Choose Our Solar Cables?
  • Superior Quality Materials: Made from premium tinned copper for excellent conductivity and corrosion resistance.
  • Optimised for Performance: Ensures efficient energy transfer with minimal losses.
  • Certified & Safe: Meets global safety standards, including TÃœV and IEC certifications.
  • Flexible & Easy to Work With: Designed for quick installation and hassle-free handling.
  • Eco-Friendly: Halogen-free and low-smoke materials reduce environmental impact.
Power Your Solar System with Confidence

Ensure the efficiency, safety, and longevity of your solar power system with our high-quality solar cables. Built to endure the toughest conditions, they’re the ideal choice for residential, commercial, and large-scale solar installations.
