  • Yongshang solar photovoltaic cables offer excellent weather and water resistance with IP67 protection (when used with MC4 connectors), suitable for:
    • Exposed rooftop installation: fully UV, temperature and rain resistant — the most common application;
    • Conduit burial: recommended to run through PVC/galvanized conduit for protection against mechanical damage and rodents;
    • Coastal/humid areas: tinned copper conductor + XLPO sheath resist salt spray corrosion;
    • Desert/cold regions: remains flexible down to -40°C without cracking.
    Important notes:
    1. Avoid friction against sharp metal roof edges — use weather-resistant clips, do not over-tighten cable ties;
    2. Use red (+) and black (-) for DC polarity to ease maintenance;
    3. Certified MC4 connectors are recommended for waterproof and reliable connections.
  • Yongshang solar photovoltaic cables have a design life of 25 years under normal operating conditions -40°C +90°C, matching the lifespan of PV modules — no mid-term replacement needed.
    Electron-beam cross-linking technology significantly enhances heat, weather and mechanical resistance;
    Passes damp heat test (EN 60068-2-78), ozone resistance test (EN 50396), cold bend test and more;
    5-year product warranty— free replacement or refund for material or manufacturing defects within the warranty period;

    Factory inspection report (COC), material certificate (MS) and certification copies are provided for customs clearance and project acceptance.


  • Yongshang solar photovoltaic cables use adouble-insulation structuredesigned for harsh outdoor PV environments:
    • Conductor: 99.99% oxygen-free tinned copper, multi-strand flexible, tin plating for anti-oxidation and corrosion resistance;
    • Insulation: XLPE / XLPO (cross-linked polyolefin), high temperature and voltage resistant;
    • Sheath: XLPO,UV-resistant, ozone-resistant, acid/alkali/salt resistant, flame retardant;
    • Voltage rating: AC 0.6/1kV, DC 1.8kV;
    • Temperature range: -40°C ~ +90°C (short-term up to +120°C).
    Regular PVC cables have single-layer insulation, no UV or high-temperature resistance, and will crack after 1-2 years outdoors. Theymust never replace solar cablefor DC inter-panel connections.

  • Yongshang solar photovoltaic cables hold multiple international certifications:

    • TÜV 2Pfg 1169: German TÜV certification, widely accepted in the EU, the core PV cable certification;
    • CE: EU mandatory conformity marking;
    • IEC 62930 / EN 50618: international PV cable standards;
    • CCC: China compulsory certification;
    • RoHS: EU restriction of hazardous substances.

    Market guidance: EU → TÜV+CE; USA → UL 4703 (customizable); Australia → AS/NZS 5033; SE Asia/Middle East → TÜV+IEC generally accepted. Please tell us your target market before ordering so we can match the right certification.

  • Cable size depends onsystem currentandcable length, with voltage drop kept below 3%.

    • 2.5mm² (14AWG): short inter-panel connections, ~30A;

    • 4mm² (12AWG): most common for residential PV, ~55A, suitable for systems ≤6kW and runs ≤10m;
    • 6mm² (10AWG): for higher-power systems or longer runs, ~70A, lower voltage drop;
    • 10mm²+: commercial plants, inverter-to-combiner box trunk lines.
    Yongshang solar cables are available in 2.5 / 4 / 6 / 10 / 16 / 25 mm², custom sizes supported.
