Single Core Solar Photovoltaic DC Cable TUV Certified PV1-F UV & Weather Resistant

Subtitle: 25-Year UV Resistant | All-Weather Durability | Low Transmission Loss | Compatible with Solar Inverters | Suitable for Solar Power Plants and Rooftop PV Projects

Introduction (Marketing-Driven + SEO & Geo-Optimization) Outdoor solar environments (intense UV radiation, extreme temperatures, wind, rain, and sandstorms) often cause ordinary cables to age, crack, or fail, reducing the efficiency of solar systems and increasing maintenance costs. The PV1-F dedicated solar photovoltaic cable addresses these pain points with photovoltaic-specific materials and structural design. This cable features high-purity stranded copper conductors, cross-linked polyethylene (XLPE) insulation, and a specially designed weather-resistant photovoltaic sheath, offering 25 years of UV resistance (compliant with IEC 60811-504 standards). It maintains stable performance in a temperature range of -40℃ to 90℃, is waterproof, dustproof, chemically resistant, and minimizes power loss for efficient solar transmission. This cable has obtained EU (CE/RoHS 3.0), North American (UL 4703), Australian (SAA), and Middle East & North Africa (SASO) certifications, making it the preferred choice for global solar developers, EPC contractors, and renewable energy projects.

PV1-F is a high-quality low-voltage (1kV) dedicated solar photovoltaic (PV) cable, specifically designed for power transmission between solar panels, combiner boxes, and inverters in outdoor solar systems. Its photovoltaic-optimized structure ensures long-term reliable operation in harsh outdoor environments: Category 5 stranded copper conductors (low resistance, flexible installation), XLPE insulation (heat resistant, anti-aging, low dielectric loss), and a specially designed photovoltaic-grade sheath (core weather-resistant layer, UV stable, abrasion resistant, waterproof). "PV1-F" definition: PV = Photovoltaic (dedicated for solar energy); 1 = Rated voltage 1kV; F = Flexible stranded conductor structure. Its unique features: Unlike ordinary outdoor cables, the PV1-F's sheath uses UV-stabilized polyolefin material with added ozone and hydrolysis-resistant additives, specifically designed for long-term exposure to solar radiation. Furthermore, it features a flame-retardant design and excellent flexibility, adapting to complex rooftop and solar power plant installation scenarios—crucial for ensuring the stability of solar systems over a 25-year lifespan.

• 25 Years of UV Resistance and Weather Resistance:

  The photovoltaic-grade sheath complies with IEC 60811-504 and UL 4703 standards and has passed 20,000 hours of accelerated UV aging testing. It will not experience performance degradation, cracking, or sheath peeling under long-term outdoor exposure (desert sun, humid coastal environments, high-altitude snow). This ensures stable performance throughout the 25-year lifespan of a typical solar project, reducing cable replacement costs.

• All-Climate Extreme Adaptability (-40℃ to 90℃):

  Features a UV-stabilized sheath with added antifreeze and high-temperature additives. It can reliably operate in extreme environments such as Arctic rooftop photovoltaic systems at -40°C, desert solar power plants at 90°C (ambient temperature + solar radiation), humid coastal environments at 60°C, and sandstorms in the Middle East and North Africa. Outdoor installations require no additional protective covers, saving project costs.

• Low-loss solar transmission:

  Utilizing high-dielectric-strength cross-linked polyethylene (XLPE) insulation, it minimizes power loss (transmission loss ≤2.2% over 100 meters with a 4mm² cross-section), thereby maximizing solar conversion efficiency. Compatible with all mainstream solar inverters (SMA, Fronius, Huawei) and combiner boxes, ensuring seamless integration with solar systems—ideal for large-scale solar power plants and distributed rooftop photovoltaic projects.

• Flame-retardant and environmentally friendly:

  Complies with IEC 60332-1-2 and UL 1685 flame-retardant standards, preventing the spread of fire in the event of a short circuit. Halogen-free and RoHS 3.0/REACH compliant, it does not produce toxic gases or corrosive fumes when burning—suitable for residential rooftop photovoltaics and industrial solar parks. Passes global green energy project environmental testing.

• Global multi-certification and efficient supply chain:

  Certified by CE/RoHS 3.0 (EU), UL 4703 (North America), SAA (Australia/New Zealand), SASO (Middle East and North Africa), and IEC 60811. A single cable meets the needs of the global solar market, avoiding the costs of duplicate certifications. In-stock availability of popular specifications (3-day express shipping) and global logistics partners (DHL/FedEx/sea freight) ensure on-time delivery, meeting the construction schedule requirements of solar projects.

Note: All specifications are in stock (fast shipping within 3 days). Bulk orders can be customized with core count (2 cores/4 cores) and cross-sectional dimensions (1.5~35mm²), guaranteeing comprehensive UV resistance, weather resistance, and regional certifications.

• What is the difference between PV1-F and ordinary outdoor PV cables?

  PV1-F is designed specifically for PV systems, featuring a PV-grade UV-stabilized sheath (25-year UV protection), while ordinary outdoor cables only offer basic UV protection (5-10 year lifespan). PV1-F also features lower transmission losses and better PV inverter compatibility—crucial for maximizing solar efficiency and long-term reliability.

• How long can PV1-F withstand UV radiation in a desert environment?

  It conforms to IEC 60811-504 standards and has passed 20,000 hours of accelerated UV aging testing (equivalent to 25 years of outdoor exposure in a desert region). The photovoltaic-grade sheath incorporates UV stabilizers to prevent embrittlement and cracking, ensuring stable performance throughout the entire lifecycle of the solar project.

• Can PV1-F be used for underground installation in solar power plants?

  Yes. Its weatherproof and corrosion-resistant sheath is suitable for underground installation (burial depth ≥ 0.5 meters). For extremely humid or corrosive soils, we recommend the PV1-F-UG version, specifically designed for underground installation, featuring enhanced waterproof filler and a corrosion-resistant sheath.

• Is PV1-F compatible with all major solar inverters and combiner boxes?

  Fully compatible. Its design matches major global solar modules (SMA, Fronius, Huawei, SolarEdge inverters; all standard combiner boxes). The cable's rated voltage (1kV) and current capacity meet solar system requirements, and we provide compatibility test reports for bulk orders.
