Solar Cable and PV Wire : A Beginners Guide

Introduction to Solar Cable and PV Wire

A solar cable 4mm is a solar cable of 4mm thickness having a minimum of two wires that are wrapped together in a protective sheath. Various manufactures are producing different varieties of solar cables. Any Cable 4mm may contain only two conductor wires wrapped in a sheath or it may contain four to five conductor wires encapsulated in a protective covering.

Based on the number of wires encapsulated in the cable, solar cables 4mm is categorized into the following types:

  1. 1
    Solar String Cables
  2. 2
    Solar Direct Current Cables
  3. 3
    Solar Alternating Current Cables
Wire Strands of Solar Cable

4mm Solar Cables

Solar wires that are bundled in a 4mm solar panel cable are manufactured using a strong material like copper or aluminum. Due to the higher conductivity of these two metals wires are capable of providing reliable conductivity. That is the reason 4mm solar panel cable is used to transport electric current from the panels to appliances placed in the home. Due to great conductivity and high-quality insulation 4mm solar panel cable is used for outdoor wiring. It is heat resistant, due to this feature it can be used in an environment where other cables may fail to perform effectively and efficiently.

6mm Solar Cables

Solar cable 6mm is a solar cable that has a thickness of 6mm. It is made up of highly conductive metals that are encapsulated in a protective sheath. The 6mm solar panel cable is very commonly used for indoor and outdoor installations. Its scheme of manufacturing and its performance made it an ideal choice for most of the electricians. Unlike ordinary cables, it can work properly in a high-temperature environment as well. It is due to its fined tuned composition and highly protective insulation sheath.

PV cable bundle

Many cables available in the market have no capacity to stand in front of ultraviolet rays but Cable 6mm has the ability to not only survive in the UV radiation environment but also capable of providing the best performance in the UV environment as well. Some mineral oils and acids can corrode the cables in outdoor installations. Due to acid rain or other causes cables are damaged in outdoor installations but fortunately, 6mm solar panel cable is very resistant to mineral oils, acids, and fire. You can install it in any environment and can enjoy the hassle-free performance. You can use it for better reliability and the best usability as well as keeping your budget stable.

Application of PV Wires

PV wire stands for a photovoltaic wire. It is a single conduit wire principally used to attach the solar panels of a photovoltaic electrical energy system. solar panels are the systems that are responsible for the production of electricity using the sunlight. They capture the sunlight and convert it into electrical energy using a mechanism of energy conversion. Electric power is generated at the panels and appropriate wiring is needed to transfer this energy to some energy collection point like batteries to store it for future use or an appliance to run the appliance. 

Red and Black PV Cables

PV wire is a unique kind of wire specifically manufactured for PV applications. The conductor materials used in PV wire are the following:

  1. 1
    Copper
  2. 2
    Aluminium 
  3. 3
    Copper-clad Aluminium 

It is highly resistant to sunlight this feature allows us to install it outdoor with great reliability. It is protected by the thicker insulation that make it suitable for surviving and performing reliably in different kind of very harsh environments. Due to thicker insulation, it can be buried directly without requiring to be shielded exclusively. The last but not the least feature of PV wire is its rating. It is one of the few single conductor wire types that can be rated over 600V.
