Solar Cable

Solar cables, also known as photovoltaic (PV) cables, are specialized cables designed specifically for solar photovoltaic systems. They are used to connect solar panels, inverters, batteries, and other components, ensuring efficient and safe power transmission.

Solar systems use photovoltaic cables. Their insulation is UV-resistant and weatherproof, capable of withstanding direct current (DC) and outdoor environmental conditions—unlike ordinary cables.

Solar cables are specially designed with UV resistance, extreme temperature resistance, moisture resistance, weather resistance, and a long lifespan (typically exceeding 25 years), features lacking in ordinary cables.

Common types of solar cables include:

• Single-core DC cables for connecting photovoltaic modules
• Solar extension cables with connectors
• Battery and inverter cables for energy storage and AC connections
• Voltage ratings are available depending on system scale, such as 600/1000/1500V DC.

The appropriate cable size depends on the current, voltage, and distance of the solar line—a larger size (e.g., 6mm²) can reduce voltage drop over long distances, while a smaller size (e.g., 4mm²) may be sufficient for short distances and low current loads.

Solar cables typically use tinned copper conductors, which have excellent conductivity and corrosion resistance, and cross-linked insulation to enhance their UV resistance and high-temperature performance.

Solar cables are rated for DC voltages of 600V, 1000V, or 1500V. Higher rated voltages ensure the safety of large solar arrays and reduce line losses.

Yes—solar cables are designed for outdoor environments and can withstand UV radiation, humidity, high temperatures, low temperatures, and other extreme weather conditions without performance degradation.

MC4 connectors are standard plug-and-play connectors commonly used on solar cables. They easily connect solar panels in series or parallel and provide a safe, waterproof connection in photovoltaic systems.

When selecting a solar cable, consider the rated voltage, current carrying capacity, UV resistance/weather resistance, insulation type, system design requirements, and compliance with safety certification standards to ensure long-term safety and performance.
