Battery Cable

Battery Cables

If you are planning to get a solar panel system at home, it’s good to understand first the cables and wirings used in solar panel units for your safety. First of all, before you can start generating renewable solar energy, you need wirings and cables to connect all the components of your solar panel system together. The type and size of cables are also important to consider.  

For today’s article, we will explain what battery cables are and the different types of solar cables.

What are Battery Cables?

A battery cable is a cable used to power your solar panel system. A solar photovoltaic system will not work without the use of cables and wiring to connect the solar panels to the solar battery and to the other system components. An inter-module cable is used to connect solar PV modules to each other while the controller-to-battery wiring connects the controller to the solar battery or battery bank.  The output cables then connect the solar array to a controller or usually an inverter, in the case of off-grid systems.

Typically, battery interconnect cables and battery to inverter cables are necessary for any system with batteries. If you want to make your own battery cables, you need crimping cable & wire tools. In addition to wiring between solar PV modules and solar batteries, and between the solar battery bank and inverter, you are required to use wiring from the combiner box to the battery bank or sometimes known as the home-run.

Solar Cable

Solar cable is made up of several insulated wires wrapped with an outer jacket. Solar professionals use them to interconnect solar PV modules to solar batteries, and to other components of a solar power system. They can handle high temperatures, high UV radiation, and have weather resistance features. Typically, these cables are installed outside or within the solar arrays.

When it comes to cable sizes, the diameter depends on the number of conductors it contains. Mostly, the classification of solar cables is based on the number of their wires and gauge. Generally, there are three common types of cables used in a photovoltaic system. These cables are DC solar cables, solar DC main cables, and solar AC connection cables.

Types of Solar Cable

• DC Solar cable

DC solar cables are either module or string cables. These cables are usually single core copper cables with insulation and sheathe. They are used within the solar panels and usually go with suitable connectors. These solar cables are pre-built into the PV modules, so replacement is not recommended.

• Main DC cable

These solar cables are either single or two-core power collector cables made to connect the positive and negative cables from the generator junction box to the solar power system’s central inverter. Main DC cable comes in a variety of sizes, usually 2mm, 4mm, and 6mm.

1. AC connection cable

The AC connection cable is responsible for connecting the inverter to its protection equipment and the electricity grid.

Before you connect those solar cables and wirings you should know what cables you are using and when they should be connected to avoid problems and damage to your solar power system. Understanding all the types and functions of each cable and wire is essential for a safe and code-compliant system.

Wholesalers

Solar Products Wholesalers 

Wholesaling refers to buying some products or goods directly from its manufacturer usually at a discount and then reselling it to the retailers for a comparatively higher cost than the original. Basically, wholesalers handle products and package them in small quantities and then sell them to retail customers, either for commercial or personal use. 

Many industries have wholesalers, and that will not skip the solar industries. Nowadays, many solar wholesale stores/firms are operating across the globe, making it much easier for retailers to go solar. Sometimes retailers find it hard to reach direct manufacturers of solar products because some companies do not have their solar stores/shops in public, with that they are not also offering solar products per piece. Through wholesale solar stores/shops, these individuals can easily buy the solar products that they need to replace or maintain their solar systems. 

If you are in need of solar product suppliers for an individual purpose, you may visit some solar outsourcing marketplace to get an updated list of solar wholesalers near your location. There are many solar platforms that provide enough information and data about the solar industry in your region, including all the reliable solar wholesalers in town.

Macao

Solar Market Outlook in Macao

The energy consumption of Macao is tremendously high and this is expected to continue its upward trend given the increasing number of large buildings. The lack of proper policies in building energy efficiency is contributing to the ineffective implementation of measures to improve building energy efficiency. 

While Macao is not among the leaders in Asia when it comes to solar power generation, the private sector has stepped up to provide an alternative source. In Macao, a company known as Melco, has collaborated with local SMEs in the development of the largest solar power plant in Macao. The project installed more than 18,000 solar PV panels spanning a total of nearly 30,000 square meters of rooftop space. This project is capable of producing up to 7.7 million kWh of energy on an annual basis (or equivalent to the energy consumption of 1,500 residents in a year).

Other private institutions have followed suit and constructed their own renewable energy systems, especially focusing on solar and wind sources. The government of Macao is also looking to amend its existing policies to provide incentives to those who are willing to invest in solar energy. 

Solar Energy Equipment Supply Capacity in Macao

You can find plenty of Macanese suppliers and manufacturers of solar power equipment. It is also possible to find global and online suppliers of solar power equipment to meet your desired capacity. 

Top 8 Major Seaports & Logistics in Macao

Macao relies heavily on its ports for its logistics and trade activities. When investing in solar power equipment, you can expect supplies to be transported via the main port in the island – the Port of Macao.
