Solar Cable: Recognizing the Basics
Solar cable is a specialized type of electrical wire designed for use in photovoltaic (PV) systems, where they play a vital role in connecting solar panels to other system components such as charge controllers, inverters, batteries, and the grid. Double XLPO and tinned copper constructions give solar panel cable excellent durability and flame retardancy, allowing them to withstand the harsh environmental conditions that solar power systems are often exposed to, such as extreme temperatures, ultraviolet (UV) radiation, moisture, and mechanical stress.
The main function of photovoltaic cables is to transmit the electricity generated by solar panels, known as direct current (DC), to an inverter, which converts it into alternating current (AC) suitable for home or business use, the standard type of electricity used in most regions. And the most commonly used are the 10AWG PV cable and 12AWG solar panel wire.
Specification of Solar Cable
As solar cables are specialized for photovoltaic power systems; they have specific specifications to ensure they meet the particular requirements of photovoltaic systems. The rated voltage range for solar wires ranges from 0.6/1KV to 2kV, the tensile load during installation is approximately 50 N/mm², and shrinkage tests are carried out at 100°C according to DIN VDE standards. And solar panel cables are available in various lengths and sizes, and the most commonly used solar cable sizes are 4mm solar cable and solar cable 6mm. Additionally, solar cable connectors are also crucial components in solar energy systems to establish secure and efficient electrical connections; common in solar panel installation are MC4 connectors.

FAQ about Solar Cable
The recommended cable size for a 300W solar panel depends on the voltage rating and distance between the panel and charge controller. Studies have found that 10 AWG solar wire is ideal for 300 watt solar panels. However, if the solar panel is rated at 24 volts and the distance between the panel and the charge controller is less than 25 feet, a 12 AWG solar cable is sufficient.
Sometimes the distance between solar panels and other components is so great that the standard cables that come with the panels may not be long enough. In such cases, you can extend the length by either purchasing solar panel extension cable or splicing additional wires to the existing ones.
The HS Code, or Harmonized Tariff Schedule (HTS) Code, is a standardized international system used for customs and international trade purposes to correctly identify and classify these products in import and export transactions. And if you are importing solar wires from China, the HS code is 8544492100.
The price of solar cables is not fixed and is affected by the price of copper. All we can offer are relative prices: 4mm solar cable price is USD 0.40 per meter to 0.50 per meter.
6mm solar cable price is USD 0.6 per meter to 0.7 per meter.
Solar panel extension cable bridges the distance between solar panels and othermodules. Common lengths for the extension cable typically range from 10 feet (3 meters) to 50 feet (15 meters), suitable for various residential and small-scale commercial solar installations. Moreover, solar extension cable is typically equipment with male and female connectors; the most common solar panel connectors are MC4.
