Things to Consider Before Buying Solar Cables

A Solar Cable is made up of multiple insulated wires that are encased in an outer jacket. Professionals use them to connect solar panels and other photovoltaic system components. They can withstand intense UV exposure, high temperatures, and adverse weather. They are usually put either outside or within the solar panels.

The diameter of a cable is determined by the number of conductors it includes. Solar cables are classified according to the number of wires and their gauge. DC solar cables, solar DC main cables, and solar AC connecting cables are the three types of cables used in a PV system.

Are all solar panel cables the same?

The conductor material and insulation of cables differ.

Copper and aluminium are the two most frequent conductivity materials used in home and commercial solar installations. Copper has a higher conductivity than aluminium, therefore it can carry more current in the same space.

Although aluminium cables are prone to bending after installation, they are less expensive than copper wires. It is not utilised (allowed) for interior residential wiring since bigger gauges are used for underground or overhead service entrances and commercial operations.

The cable could be solid or stranded, with stranded wires consisting of many little wires that allow the wire to be flexible. For larger sizes, this kind is recommended. Because current flows around the outside of the wire, stranded wires offer slightly superior conductivity due to the increased wire surface area.

Insulation: Heat, moisture, ultraviolet light, and chemicals can all be protected by the insulation that covers the cable.

How do I choose a solar cable?

The sort of solar cable you use is determined by the type of solar energy project you're working on. You may, for example, have connected two solar panel modules in series with the proper solar cable size. The electricity from those modules must then be transported to a location where electrical equipment, a circuit breaker, or a charge controller can be found. You'll need an MC4 solar cable for this. So, what are the functions and properties of these cables?

The solar wire functions similarly to an extension cable, with male and female connectors on both ends. When connecting two or more modules in series, one end of the MC4 cable is plugged into the terminal end of the solar panel wire connecting the cables, while the other end (the MC4 solar cable extension) is plugged into the equipment or power distribution circuit. If your application is unique, you may want to go with a 10 AWG solar cable. So that's the cable you'll need to choose.

Other considerations, such as cable rating and specific operating temperature requirements, may influence how you choose the proper solar cable. While a USW-2 cable can handle up to 600 volts, DC wire for solar panels comes in a variety of voltage levels, including 600 volts, 1 kV, and 2 kV. As a result, you may have more alternatives when it comes to selecting the right solar cable size. Additionally, while USE-2 wires have a maximum operating temperature of roughly 90oC, you can buy wire that is rated to greater temperatures than 90oC depending on the solar cable manufacturer you choose and the solar panel cable size you choose.

Your solar wire selection may also be influenced by your application requirements. If a single-conductor cable is required, solar panel wire is one of the few wires and cables available that fit those requirements. It's also one of the few 600-plus V wires that, according to NEC requirements, can be buried without shielding.

What is the best wire for solar panels?

You'll likely have a wide range of cables and wires to pick from, depending on which Australian cable manufacturers you work with. To make matters even more complicated, each manufacturer's solar cable pricing quote for the identical PV cable offered in each catalogue could be drastically different. So, how do you get the most bang for your buck as a buyer of wires and cables for your solar power project?

It's critical to choose a solar cable company with a proven track record of making and supplying the highest-quality solar cable available.
