Solar Cable Vs Other Electric Cable

Solar Cable Vs Other Electric Cable

We might use normal ordinary electrical cables in our houses and industries, but do you ever think about safety and durability, because safety is a must in electric transmission?

Features of a Solar Cable

The voltage rating and length of the solar panel cable are two of its most crucial characteristics. Information about voltage ratings is available on our product pages and is mostly based on the wire’s gauge.

The length of the cable is also a crucial factor because it affects the voltage rating because resistance rises as cable lengths increase, necessitating the use of slightly thicker gauge cables over longer distances.

Regardless of the electrical wiring scenario, the voltage rating and length are nevertheless vital considerations to take into account. Otherwise, it would be feasible to install a solar power array using any kind of wire or cable, which is not the case.

Among its many attributes, our welding wire for solar panels are said to be resistant to sunlight and the elements, as you can see if you take a closer look. It doesn’t take much thought to try to figure out why this would be the case.

Difference Between Solar Cable and Normal Electric Cable

  • Insulation and specification

Solar cables are often insulated with a substance that is resistant to UV rays, moisture, and extremely high or low temperatures.

Cross-linked polyethylene (XLPE), which has outstanding electrical qualities and is resistant to heat, sunlight, and weathering, is the most typical insulation material used for solar cables.

Other insulation materials used in solar cables include polyvinylidene fluoride (PVDF), which is recognized for its resistance to chemicals and harsh temperatures, and ethylene propylene diene monomer (EPDM), which is known for its excellent resistance to weathering.

  • Voltage Range

Compared to conventional cables, solar cables have a higher voltage rating. This is due to the fact that they are built to withstand the enormous DC voltages that solar panels may produce, which can be in the region of 600 volts to 1500

When used in a solar power system, standard electrical lines may not be rated for these high voltages, posing a risk of fire and electrical shock.

  • Durability

Solar cables are made to resist the challenging external elements that solar power systems must contend with.

They sustain their performance over an extended period of time thanks to their resistance to weathering, abrasion, and chemical exposure.

Solar cables’ insulation is made to withstand cracking and degradation brought on by exposure to UV rays, moisture, and severe temperatures.

A coating of insulation is frequently applied to solar cables as an additional layer of defense against abrasion and wildlife damage. The solar power system’s dependability and lifespan are enhanced by its durability.

  • Conductor Material

Tinted copper, which is more resistant to corrosion and oxidation than bare copper, is frequently used in solar cables. Tin is applied to the copper during the tinning process to help shield it from moisture and other external elements. Other cables might use aluminum or conductors made of bare copper.

  • Cross-Sectional Area

The cross-sectional area of solar cables is frequently greater than that of other cables since this helps lower resistance and boost system efficiency.

The size, voltage, and distance between the solar panels and the inverter will all affect how much cable is required.

  • Standards and Certifications

Compared to ordinary cables, solar cables are subject to distinct standards and certifications.  

To ensure safety and performance, it’s critical to make sure the cables used in solar power systems are approved and adhere to local standards.


Specialized connectors created expressly for use in solar power systems are frequently found on solar cables.

These connections are made to withstand weather conditions, be simple to install, and work with solar systems’ high voltages and currents.

Standard electrical connectors might not be appropriate for solar power or power systems, which could lead to safety risks or decreased performance.

Wrapping up

Solar cables are distinct from ordinary cables in a number of significant aspects and are created expressly for use in photovoltaic power systems.  

They have a greater voltage rating than normal cables to withstand the high DC voltages produced by solar panels. For durability and safety, you have to find one of the best solar cable manufacturers so that quality will be the focus. Energy Cable is an electrical cable manufacturer in Australia.
