What Is Solar Wire And Cable?
Solar cable wire are cables specially designed for the safe transmission of DC solar energy in photovoltaic systems. These solar cables wire are designed with high mechanical strength to withstand the demanding requirements of photovoltaic systems as well as harsh weather conditions.
While both DC and AC cables are an important part of a solar photovoltaic system, they are used in solar power plants to produce solar energy for homes, businesses and industries. Solar PV systems can only have a 25-year life expectancy if the cables used to produce solar energy for residential, industrial, commercial rooftop or ground-mounted solar plants are of sufficient size and quality.
Types of Solar Wire And Cable
In solar power projects, different types of solar cables are required to generate solar energy. Both DC and AC cables are used in solar power plants. Photovoltaic panels and inverters (including junction boxes) are connected by direct current (DC) cables, while inverters and substations are connected by alternating current (AC) cables.
Furthermore, different voltage levels from low to ultra-high are used in standard solar PV projects, depending on the requirements. And the low-voltage power cables are used to connect the panel to the combiner box, the combiner box to the inverter, and the inverter to the transformer. On the other hand, medium voltage power cables are used to connect transformers to substations, while high voltage and extra high voltage power cables are used to connect substations to the grid.
The Reason Of Solar Wire And Cable In PV Projects
Solar cable wire used in solar power plants are specially designed to safely transmit DC solar energy from one part of a photovoltaic installation to another. Proper cable management is one of the most important aspects of the safety and longevity of every photovoltaic (PV) system.
As solar cable installations in any solar project are exposed to direct solar radiation, they are also subjected to extreme temperatures and air humidity. Therefore, solar cables are designed with high mechanical strength to withstand the demanding requirements of photovoltaic systems both indoors and outdoors, as well as harsh weather conditions.
Not only must these solar cable wire be strong, but they should also be weather resistant. They are also subjected to mechanical stresses caused by compression, bending or tension during installation. In addition, solar cables are exposed to chemical stress in the form of acids, alkaline solutions and salt water.
Since ordinary cables cannot handle these harsh conditions as well as the overheating effects of solar panels, solar cables are designed to avoid problems such as overheating, low reliability, durability and power loss. Therefore, these cables are the main connecting elements that help the photovoltaic system to function properly.
Selecting High Quality Solar Wire and Cable
Cable companies put a lot of effort into making solar cables suitable for the most demanding applications. Efforts have been made to produce solar cables with the highest resistance to atmospheric challenges such as UV rays, ozone and humidity. In addition, it is important that they withstand harsh temperatures (-40°C to 120°C), the harshest weather conditions, and have high resistance to abrasion, impact, tear and compression.
Since solar wires and cables must be installed outdoors, they must withstand extremely harsh operating conditions. This requires that these cables must be designed
Good weather resistance, ozone resistance, UV resistance
Can withstand a wide temperature range, typically -40 ℃ to 120 ℃
Withstands mechanical stress such as compression, tension, bending and shear loads
Abrasion resistance, acid and alkali resistance, flame retardant and halogen-free
high dielectric strength and have a small diameter
rodent and termite resistant
The quality, safety and profitability of a solar power plant depends on the workmanship and efficiency of its components.
The Importance Of High Quality Solar Wire And Cable
The efficiency, reliability and profitability of a solar power plant depend on the quality of its components. Choosing the correct solar cable for your solar system is important if you want your solar system to function properly and stay intact. Since solar PV systems have a useful life of more than 25 years, sourcing solar cables from licensed and approved manufacturers is essential to ensure quality and safety.
Solar wires and cables make up a small share of the value of a solar project, but at the same time play a very critical role in its overall efficiency and long-term stability. So sacrificing quality in order to cut costs is not a wise decision in my opinion.
As solar cable witres are the lifeline of a solar grid, proper selection of wires and cables is critical in the long run as poor quality cables lead to higher maintenance costs.
