What Makes a Panel of a Solar Energy System?

Solar panels are quite popular among homeowners in Brisbane. If you are interested in purchasing solar panels, you will need to have a complete understanding of what they are all about. That’s where the understanding of how solar panels are made can help you. When you have this understanding, you can easily approach the best solar panel installers in Brisbane and make an informed decision to get a solar panel system. Let’s take a look at what makes a panel of a solar energy system…

What are the major components of a solar energy system?

Solar panel systems in Brisbane are made out of 10 major components. All these components play a major role in the overall functionality of solar panels. The components include:

  • Solar cells
  • Glass
  • Wires
  • Bus bars
  • Back sheet
  • Frames
  • Diodes
  • Connectors
  • Anti-reflective coating
  • Junction box

The role of each part in the panel of a Solar Energy System?

Now that you know what makes a solar energy system, let’s take a look at the functionality of each and every component mentioned above. Then you can understand how solar systems suppliers Brisbane manufacture the solar panel systems installed at your home.

Solar Cells

Solar cells are small square or rectangular-shaped components, which you can discover within a solar module. People often call solar cells PV cells. These cells are made out of semiconductors. The main objective of PV cells is to collect energy from the sun and convert that into DC current. You can use an inverter for converting DC current into AC current. This is one of the key elements that make a solar energy system.

Bus Bars

You will need to use bus bars to connect solar cells together. Bus bars are nothing but connectors, which create a connection between the PV cells. These bars are made from silver metal strips. Hence, you can expect them to deliver an excellent conductivity for electricity. Bus bars are the silver lines, which you can see in the solar panels. When PV cells generate electricity, bus bars facilitate the flow of electricity. The best solar panels in Brisbane come along with premium quality bus bars.

Glass panels

You can see the glass panels on the front side as well as on the rear side of solar panels. Glass acts in the form of a protective layer. The most common type of glass you can discover is tempered glass. Hence, you don’t have to worry too much about the durability of glass present in the solar panels. The glass panels you can find in solar panels undergo numerous tests. They include fire tests, hail storm tests, sand abrasion tests, corrosion tests, snow load tests, and many more. When you buy solar panels in Brisbane, you can continue to use them for many years because of the protection offered by these glass panels. Glass panels contribute to around 40% to 70% of the overall solar panel construction as well.

Wires in solar panels

You can see wires on the output panel of your solar panel modules. These are traditional copper wires. However, these wires are covered with PVC or XLPE to provide heat protection and insulation. Electricity carried by bus bars will flow into the wires. Then electricity will go through diodes present in the junction box. You can discover both negative as well as positive terminals in solar panels. However, these negative and positive wires are a part of the solar module. The lengthy of wires would vary from one manufacturer to another. When you buy solar panels in Brisbane, you need to take a look at the length of the wires and see if that is sufficient for you. This is what makes the panel of a solar energy system transfer it’s energy to the rest of the system.

Junction box

You can usually discover the junction box on the upper rear side of solar modules. Inside the junction box, you can discover panel diodes. It is even possible to see cables coming out of the junction box. Since the junction box contains diodes, it is important to ensure internal components from water and dust damage. That’s why the junction box that you can get along with Brisbane home solar panels comes along with IP67 or IP68 rating.

Solar module frame

The solar module frame is responsible for holding the entire weight of the solar module. On the other hand, the frame can contribute to improving tensile strength. There are some important mechanical attributes present in the solar module. They include fixation, handling, storage, grounding, snow load resistant, and wind load resistance.

Connectors are responsible for connecting one solar module with another. In fact, the connectors contribute towards creating a solar PV string. The solar panel installers in Brisbane would connect them via connectors. These connectors are plastic-made, and you can discover negative and positive output terminals in them.


Diodes are present within the junction box. The solar panels in Brisbane use diodes for numerous purposes. However, the main objective of diodes is to prevent the backflow of electricity. Likewise, diodes can enhance the reliability of the solar modules by functioning in the form of an entire module.

How is the panel of a Solar Energy System made?

Now you are aware of the most prominent components that are present within the solar panels in Brisbane. It’s beneficial to find out how the manufacturer makes solar panels. The four main materials in solar panels are silicon, aluminium, silver, and copper. The most popular material used for the construction of solar panels is silicon. That’s mainly due to the availability of silicon as an inexpensive material. You will be able to get solar power systems in Brisbane at an affordable price since they are made out of silicon.
There is a belief that solar panels are made out of coal. Sand transforms into silicon through heating. The solar panel manufacturers burn coal for manufacturing silicon. That’s because burning coal can effectively heat up sand until it reaches the melting point. We believe this gave a good idea to you about what makes a solar panel of a solar energy system.

While keeping these facts in mind, make sure that you invest your money in the best Brisbane home solar panels. Then you can get the most out of your investment. We hope you managed to get a clear idea about what makes a Solar Energy System. DJ Solar can source & install a full system for you. Please Click here to see our packages and prices.
