Solar cables Manufacturers online

Solar cables or photovoltaic cables have been specially developed for use in photovoltaic systems. During development, particular attention was paid to resistance to UV radiation and the ability to withstand high temperatures and moisture.

1. Function and significance:
Solar cables are special electrical cables that have been developed for use in photovoltaic systems. They are used to conduct the direct current (DC) generated by the solar modules either to a battery storage system or to an inverter, which converts the current into alternating current (AC) for feeding into the power grid.

2. Features:
As solar cables are often laid outdoors, they must be resistant to UV radiation so that they do not become brittle or lose their insulation.
Solar cables must be able to withstand extreme temperatures, humidity and other weather conditions.
They must be designed for high voltages in order to safely transport the direct current generated.
These cables are often flexible to allow easy installation in different environments.
In case of fire, the cables should produce little smoke and not release halogen-containing compounds to increase safety.

3. Types of solar cables:
Single core solar cables are commonly used for cabling between the solar panels and the inverter.
Multi-core solar cables are less common, but are used in special applications or for larger installations.

4. Installation requirements:
Solar cables can be laid over roof surfaces, in cable ducts or directly in the ground. During installation, care must be taken to ensure adequate ventilation and protection against mechanical damage.
The cross-section of the solar cable must be carefully selected in order to minimize the voltage drop and ensure the efficiency of the system. Typical cross-sections are between 2.5 mm² and 10 mm², depending on the system configuration and the length of the cable runs.
The connections between the solar modules and the inverter must be well insulated and watertight. Special connectors such as MC4 are often used for this purpose.

5. Standards and regulations:
Solar cables must comply with specific standards, such as EN 50618 in Europe, which specifies requirements for the electrical and mechanical resistance of cables for photovoltaic systems.
In addition, local installation regulations and safety requirements should be observed.

6. Service life and maintenance:
Solar cables are designed for a long service life, often up to 25-30 years. However, regular inspections for mechanical damage or signs of ageing are necessary to ensure the safety and efficiency of the system.

When purchasing solar cables, there are several important factors that should be considered to ensure the longevity, safety and efficiency of a photovoltaic system:

• High-quality solar cables are usually made of tinned copper, which offers high conductivity and resists corrosion.
• Solar cables should be specially designed for outdoor use and be resistant to UV rays to prevent premature ageing.
  Make sure that the cables are designed to withstand extreme temperatures and humidity in order to function reliably even under adverse conditions.
• Ensure double insulation with high-quality materials such as XLPE (cross-linked polyethylene) or EPR (ethylene propylene rubber), which are UV-resistant, weatherproof and mechanically robust.
• Make sure that the cables are designed for the voltage required in your system (typically 600-1000 V DC).
• The cable cross-section should be selected to match the current load in order to avoid overheating and energy losses. The cross-section depends on the power of the system and the length of the cable runs.
• Ensure that the solar cables are certified in accordance with the relevant standards, such as **EN 50618** (for Europe) or **UL 4703** (for the North American market). These standards guarantee compliance with safety and quality standards.
• Choose cables that are flexible enough to facilitate installation, especially in complex or confined installation paths.
• The cables should be kink-resistant to withstand mechanical stress during installation and operation.
• Make sure that the cables are compatible with the required connectors (such as MC4) to ensure safe and easy installation.
• Compare prices and consider the quality of the cables. Cheaper cables may seem attractive at first, but may have a shorter lifespan or higher installation and maintenance costs.
• Check whether the manufacturer offers a warranty on the cables and whether technical support is available in case of problems. A 25-year warranty is not uncommon for high-quality solar cables.

By considering these points, you will ensure that you choose solar cables that are reliable, durable and will allow your photovoltaic system to perform optimally.
