Top Features That Make Solsquare Solar Cables Long-Lasting

In the current living environment that routinely changes rapidly, solar energy has emerged as one of the most reliable sources of electricity and one of the most sustainable energy sources.

Solsquare Solar Cables Long-Lasting

Despite the size of the solar installation - be it a small rooftop setup or a large-scale solar farm, the efficiency and safety of a solar installation is strongly subjective to the quality of the material used. The most important among those is the solar cables since they are the ones that conduct electricity produced by solar panels to the inverter and other parts of the device.

The low quality of cables may cause the loss of power, their overheating, fire, and cost. This is the part on which Solsquare Solar Cables excel at. Solsquare cables are manufactured with expertise, tested assuring durability, and made to last long in performance. Today, in this blog, we shall elucidate the best facilitating features that confer an extended life to Solsquare Solar Cables and why it is the best in its kind and suited to your Solar Project.

1. Premium Copper Conductors for Maximum Efficiency

The conductor material inside a cable plays a vital role in its performance. Solsquare uses flexible electrolytic tinned fine copper strands as per IEC 60228, Class 5 standards. Copper offers:

  • Low resistivity, which minimizes energy loss during transmission.
  • Flexibility, making the cables easy to install in different setups.
  • Corrosion resistance, protecting the cables from degradation.
  • Maximum strength and stability that guarantees stability and always performs to the same degree of performance over decades.

However, in contrast to aluminium solutions, copper-based cables are more conductive and durable, i.e. more efficient and long-lasting.

2. Designed for Harsh Outdoor Conditions

Solar cables operate in harsh weather conditions, which are scorching heat, heavy rain, snow, dust, and wind. UV resistant and weatherproof, Solsquare Solar Cables may be used in the outdoors long-term.

The cables are insulated and sheathed to prevent them against cracking, hardening, and degrading under the influence of sunlight and their design enables it to be used reliably in extreme climate settings.

3. Wide Temperature Operating Range

The heating and cooling from temperature change presents a challenge for many solar cables. While some projects are based in the desert with high heat, others may involve snow and extreme cold. Solsquare Solar Cables have conductors rated to a safe operational temperature range of -40°C to +120°C where performance is not compromised regardless of the operating temperature range.

The wide operational temperature range is one of the advantages that allow these cables to operate reliably for up to 30 years.

4. Flame Retardant-Low Smoke

Fire safety is inherently critical when dealing with solar systems. Poor quality cables are prone to overheating, short-circuiting, and can also contribute to fire accidents. Solsquare cables are produced with materials that have flame retardant properties, therefore they will not allow the spread of fire.

They are also low smoke emitters to ensure, in the unlikely event of an electrical fault or fire incident, we can at least keep people and property safer from smoke, should an incident arise.

5. Halogen-Free Insulation for Added Safety

Many conventional cables use halogen-based materials that will produce toxic gases when burned. Solsquare incorporates crosslinked halogen free insulated material that is fire resistant and environment friendly.

This will ensure that in case of a fire, cables do not release toxic halogen gases, as happened to be the case with the past cables, saving both lives and environment.

6. Life Expectancy / Lifespan of 30 Years

Solsquare Solar Cables (Solsquare) are designed to last. They are manufactured in accordance with EN 50618, with an expected design service life of 30 years. The long life expectancy / lifespan, of Solsquare Solar Cables (Solsquare), means they are cost-effective because you do not need to worry about replacing them regularly or incurring downtime with your solar energy system.

7. Superior Mechanical Strength

It is not only the durability in electrical performance but also about the mechanical strength Solsquare cables have been built to prove resistance to physical challenges such as pulling, bending or even vibrations during installation and use.

Such strength renders them appropriate to a variety of uses, such as roof-top, mobile solar, underground, and industrial applications.

8. Tested and Quality Checked

All Solsquare cables have a stringent production and test regime. With every step between raw material choice and a finished product, cables show stable performance, safety and reliability.

This is an advantage that Solsquare boasts of in terms of its high-precision manufacturing and quality assurance capacity in the solar cable industry.

9. Compliance with International Standards

Solsquare Solar Cables meet international standards with regards to manufacturing including: EN 50618 and IEC 60228. This will guarantee the superior levels of safety, performance and reliability of the cables. To the project developers and the end-user this delivers assurance that the product is certified and recognized internationally.

10. Versatile Applications

Solsquare Solar Cables are not limited to one type of installation. They are suitable for:

  • Rooftop solar systems
  • Ground-mounted solar farms
  • Mobile solar power units
  • Architecturally integrated photovoltaic systems
  • Hazardous industrial areas
  • Underground and overhead installations

FAQs

The built-in ordinary cables cannot serve the peculiar needs of solar projects. Solsquare cables are designed to be UV resistant, flame resistant, with heavyweight insulation, and durability that last up to 30 years.
Yes. They are also introduced to broad operation temperature range (-40°C to 120°C) and have resistance against UV radiation, rain and dust, and are ideal to operate under harsh conditions outdoors.
Solar modules last up to 30 years and as such their reliability over the lifespan of solar projects is assured.
Absolutely. It is applicable in small rooftops, large solar farms and grid-tied commercial applications as well as high risk industrial sections.
Yes. They are in line with EN 50618 and IEC 60228 regulations whose guidelines are accepted worldwide with regard to the factors of solar cable safety and performance.
They are made from flexible electrolytic tinned fine copper strands, which provide excellent conductivity, corrosion resistance, and mechanical strength.

Conclusion

The best component in a solar project is only effective as its worst component. Solar panels and inverters may be the first things people think of, but if there were no cables, the system would have no life. The use of the low-quality cables may result in power losses, accident risks, and a lot of repair work.

Solsquare Solar Cables are developed in order to exclude these challenges. Their premium copper conductors, UV and weather-resistance, as well as flame retardant and halogen-free insulation also provide longevity and safety, renowned to be up to 30 years.

Designed to be used in small residential rooftop solutions as well as large industrial solar farms, Solsquare cables allow optimizing the proposed solutions in terms of efficiency, safety, and reliability of the solar system over decades.
