There are a few things you should keep in mind while you’re out buying solar cables. This guide will go over six of the most important points to remember!

What is Solar Cable?

A Solar Cable is a connecting cable used for photovoltaic power generation. Solar cables connect the solar modules and other electrical components of a photovoltaic system. The solar cable is UV and weather resistant. It can be used in a wide temperature range.

Specific performance requirements for materials used in wiring solar panel installations are specified in the national and local electrical codes that govern local electrical installations. General properties required for solar cables are resistance to ultraviolet light, weather, local temperature extremes, and insulation suitable for the voltage rating of the equipment. Some jurisdictions have specific regulations regarding the grounding (grounding) of photovoltaic systems to protect against electric shock and lightning strikes.

Types of Solar Cables

Solar energy projects require different types of cables to get the job done. Both DC and AC cables are used. The PV module and the inverter, including the junction box, are connected via DC cables. Meanwhile, the inverter and the substation are connected by AC cables.

  • DC Solar Cable: DC solar cable is a single core copper cable with insulation and sheath. They are used in PV solar panels and can be either panel cables or string cables. The also comes with appropriate connectors and is pre-assembled to the panel. Therefore, they cannot be changed. In some cases, a string DC solar cable is required to connect to other modules.
  • Solar DC Main Cable: The main DC cable is the larger collector cable. They connect the positive and negative cables from the generator junction box to the central inverter.  In addition, you can use single-core or double-core cables. Solid double insulated cable is a practical solution that offers high reliability. A 2-wire DC cable is the best choice for wiring between the solar inverter and the combiner box. Professionals usually prefer DC main solar cables for outdoor installations. Sizes typically range from 2mm, 4mm and 6mm.Tip: Route opposite polarity cables separately to avoid short circuits and grounding problems.
  • AC Connection Cable: AC cables connect the solar inverter to the protection device and the power grid. For small PV systems with three-phase inverters, use a 5-wire AC cable to connect to the grid. The arrangement of the wires is as follows:

    1. 3 live wires for carrying electricity
    2. One for ground and one for neutral.

    Tip: If your PV system has a single-phase inverter, please use a 3-wire AC cable.

The Benefits of Using Solar Cables

  • For solar energy There are many benefits to using solar cables for solar energy.  Solar cables are durable and can withstand high temperatures, making them ideal for use in solar energy applications.

  • Solar cables are also flexible, making them easy to install and connecting multiple solar panels together.

  • Solar cables are also relatively inexpensive, making them a cost-effective option for solar energy projects.

The Future of Solar Cables

As the demand for renewable energy increases, the need for solar cables also increases. The future of solar cables looks promising, with new technologies and materials being developed all the time. The goal is to make solar cables more efficient and durable, so that they can be used in a variety of applications.

5 Points to Remember while Buying Solar Cable

  1. Select the right type of cable for your needs: There are different types of solar cables available in the market, so it is important to select the right type of cable depending on your needs. Some of the popular types of solar cables include PV wire, solar power cable, and solar panel cable.
  2. Consider the voltage and amperage rating: The voltage and amperage rating of the solar cable is an important factor to consider while making a purchase. Make sure to select a cable that can handle the maximum voltage and amperage output of your solar panel.
  3. Choose the right length: The length of the solar cable is another important factor to consider. You need to make sure that the cable is long enough to reach from the solar panel to the batteries or inverter.
  4. Select the right connector type: The type of connector used in the solar cable is also an important factor to consider. Make sure to select a connector that is compatible with the solar panel and the batteries or inverter.
  5. Consider the price: The price of the solar cable is an important factor to consider while making a purchase. Make sure to select a cable that is affordable and also meets your needs.
