An evaluation of Sri Lanka’s solar market

Sri Lanka is arguably one of the fastest developing economies in the South Asian region. This is surprising for most people because the nation recently came out of a civil war spanning three decades.  Do these excellent fortunes extend to the country’s solar market?

At the end of 2019, Sri Lanka’s solar capacity stood at 215 Megawatts, 10% of the country’s collective renewable capacity. The nation’s solar energy capacity is expected to hit 1.5 Gigawatts by 2025. This foreseen increase in the nation’s solar aptitude is primarily attributed to the Renewable Energy development plan of 2019 -2025.

So far, the Ceylon Electricity Board, the plan’s implementation body, has awarded tenders for 300 and 500 Megawatts. According to recent studies, these projects will go a long way in quelling approximately 2 Gigawatts of solar energy demand expected in the foreseeable future. If the government of Sri Lanka maintains its support for renewables, solar installers and professionals can expect vast opportunities in the future.

Sri Lanka’s solar market equipment supply capacity

You can expect to find various solar equipment categories, including solar panels and charge controllers in Sri Lanka. Still, if you can’t find what you need locally because the Solarfeeds family is here for you. You can get competitive quotes by sending a request through our website’s inquiry page. Also, you don’t need to worry about how you will receive your equipment.  Sri Lanka boasts of several ports and a healthy logistical network to deliver any solar equipment.

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.
