In the recent years, most of the people worldwide are shifting to photovoltaic energy systems. The system is famous for utilizing solar energy and converting it into electrical energy. The system comprises of some essential components to work, one of which is a solar cable.

So a solar cable plays an important role in every solar project. A solar cable works as an interconnecting tool between solar panels and other electrical component in a photovoltaic system.

Importance of Quality of Solar Cables

Solar cables are the lifeline of a solar system that connects every individual panel ensuring that the system works. While buying solar cables, ensuring the best quality of the cable should be your priority. Solar panel has a minimum life of 25 years. Therefore, the components attached should be reliable to support this expected duration. Cable installations in any solar projects are usually exposed to direct sunlight and extreme weather conditions.

Moreover, you can use these solar cables by roof mounting or burring in the earth directly. Thus, it is essential that the cable should be strong and sturdy. In addition, the cable should be capable of bearing both chemical in the form of acids, salts, and mechanical stress as during installation. More specifically, the cable insulation and sheathing material determines its characteristics.

Why Sizing is Important in Solar Cables?

Sizing is one of the most crucial components especially when it comes to connecting different wires to the Photovoltaic system. To avoid incidents such as overheating and short fuses due to power surge, you should not overlook the matter of sizing. Experts advise to go overboard on the cable you need, as an undersized cable may lead to a lot damage. For instance, if the cable is not capable of handling the extra power, it can cause a fire in the system.

Difference in cable and a wire?

A cable consists of many small wires inside it. For example, a 4 mm cable has various small wires enveloped in the cable which supplies electricity between the endpoints in a solar setup.

Some people also prefer using a 6mm cable due to its various advantages. They mostly use it in outdoor wiring as it claims to be weather resistant and comes with a protective cover.

Material Matters:

The two most widely used conductor material in residential and commercial solar installations are copper and aluminum. The cable made up of copper has a greater tendency of current carrying than the cable of aluminum of the same size. Thus, making copper more expensive.


Moreover, for projects such as for interior home wiring, experts usually recommend to not use aluminum as its capability to bend mostly during installations. There are various materials available in market but it is important to choose the right one that matches your need perfectly.

All in all, the use of solar systems is one of the most effective way to conserve energy. Not only it is environment friendly but also pocket friendly in the long term.
