The demand for solar panels continues to increase annually. Certain solar panel manufacturers in Australia opt for a manual method of producing solar panels. Others prefer full automation to ensure the highest quality standards.  

Solar panels are composed of solar cells that transform sunlight into electrical energy. Silicon is the primary material used in the production of solar panels. Many you see on rooftops are either monocrystalline or polycrystalline.   

The solar panel manufacturing process in Australia has a significant impact on the country’s energy efficiency. As more people transition to solar energy, it’s essential to understand how solar panels are created.  

This article provides a comprehensive overview, from the vital components to the machinery involved.

Background on Solar Energy

Solar panels have undergone significant advancements in their effectiveness over the years. Before the development of the first silicon photovoltaic cells in 1954, numerous scientists contributed to the growth of solar technology as we now know it.   

The initial silicon cell was created in 1954. It had an efficiency of only 4%. However, as research advances, the efficiency ratings also continue to improve.  

Today, the solar cells in use can meet the electricity needs of both commercial and residential properties. Solar panels are also increasingly generating power for businesses and industrial operations. It can soon become the primary energy source for powering economies.

Solar Panels Components for Manufacturing

A solar panel is a device composed of several elements that facilitate the conversion of sunlight into electricity while safeguarding it from external weather conditions.   

The primary and essential element required for producing solar cells is pure silicon. However, silicon does not occur naturally in a pure form. It is obtained from quartz sand through a high-temperature furnace process.   

The principal source of obtaining pure silicon is natural beach sand. Despite its widespread availability globally, producing pure silicon is a costly process.  

Here are the components to create a fully functional solar panel:  

  • Solar Cells  
  • EVA Film  
  • Polymer Back sheet  
  • Tempered Glass  
  • Aluminium Frame  
  • Junction Box & Connectors  
  • Silicone Sealant  
  • Copper Ribbon  
  • Packaging Materials 

Essential Machinery for Solar Panel Manufacturing

The production of solar panels is a multi-stage process that utilises various machines to ensure smooth production. Here are the types of machinery used to make quality solar panels:   

  • Cell Testing Machine  
  • Laser Cutting Machine  
  • Solar Cell Stringer Machine  
  • Glass Loading Machine  
  • Soldering Machine  
  • EL Testing Machine  
  • Lamination Machine  
  • Solar Panel Frame Punching Machine  
  • Sun Simulator Testing Machine

Solar Panel Manufacturing Process

The production process requires precise and careful steps to ensure quality solar panels. So, how are solar panels made step by step?   

The initial step in producing solar panels involves purifying silicon, which is extracted from quartz sand. After obtaining purified silicon, it is mixed into solid formations, typically forming cylindrical ingots.   

This fusion is accomplished within a specialised steel cylindrical furnace, carefully ensuring all atoms align according to the desired orientation and structure. 

Production of Wafers

The subsequent stage in solar panel manufacturing follows the creation of ingots. The cylindrical ingot is meticulously sliced to produce wafers into thin, disk-shaped pieces.   

This slicing process is typically conducted one at a time using a cylindrical saw. However, some manufacturers use multi-wire saws to cut multiple wafers simultaneously.  

Thin silicon exhibits a reflective quality that can lead to light loss. Therefore, a thin anti-reflective coating is applied to these disks to reduce sunlight reflection.   

This coating substance can be heated until its molecules evaporate. During sputtering, manufacturers employ high voltage to displace the molecules from the coating and deposit them onto the silicon.  

The wafers undergo additional polishing to eliminate saw marks. However, some manufacturers opt to retain these marks as they contribute to increased efficiency.   

Solar Cell Strings

The process begins by collecting essential raw materials near the assembly line, including solar cells, glass, and EVA film.  

The solar cell is a crucial raw material for creating solar panels, often found externally. Each box of solar cells contains 12 packets, each with 120 cells. In total, it will have 1440 cells.  

These cells are removed from the box, loaded into a magazine, and placed in the stringer machine for forming cell strings. The same stringer machine is employed regardless of the desired solar panel type.  

Robotic arms on this machine place the solar cells on a belt and attach ribbon layers to them. Then, the string is cut to the specified cell count according to the input requirements. The solar string undergoes visual inspection for defects and proceeds to the subsequent stage.

Transforming Solar Cell Strings into Solar Panels

Another assembly line operates where toughened glass is readied, and an EVA film is applied before moving to the next phase. During this phase, robotic arms accurately position the solar strings onto the toughened glass and EVA film.  

A panel with 72 cells is composed of 6 strings, each containing 12 cells. These partial solar panels are stacked and then managed by various manual teams.  

The first team applies transparent tape to secure the string in position, a crucial step for maintaining alignment throughout the subsequent lamination process. The panel then advances to a team that performs soldering.  

Excess materials left after soldering are removed by the subsequent team. The following section applies an RFID tag and brand logo to the panel.  

Subsequently, the panel proceeds to the final conveyor belt stage, where another layer of EVA film and a polymer sheet are applied on top, along with an attached barcode. This barcode feeds panel data into a computer system.

Laminating the Solar Panel

Before lamination, the solar panels undergo an EL test that detects even the tiniest string cracks, which are invisible to the human eye.  

This test is essential because a defect found post-lamination can lead to issues with raw materials. Defective pieces are sent back for correction.  

Following the EL test, the panels enter the lamination process. Stacks of panels are placed into the lamination machine. Each cycle laminates five solar panels in approximately 14 to 15 minutes.  

After lamination, the panels emerge from the machine at elevated temperatures and are cooled by fans for 2 to 3 minutes. 

Trimming and Visual Inspection of Solar Panels

After cooling, the panels undergo trimming to remove excess material from lamination, a manual process.  

The next machine performs a visual inspection, meticulously checking each aspect based on a checklist. Only panels passing this inspection proceed to the subsequent stage.

Incorporating a Metal Frame

In the final assembly phase, frames are constructed according to size specifications, with manual and automated processes aligning the frame and filling the sealant.  

Subsequently, the frames are connected to the panel using a punching machine. A manual inspection confirms proper frame attachment.

Attaching a Junction Box

The final step involves attaching a junction box to the panel’s rear using the sealant. The panel is left to dry, allowing the sealant and frame to set fully.  

After drying, the solar panel undergoes cleaning to remove chemical and sealant stains that might affect its performance.

Solar Panel Testing

The final step involves attaching a junction box to the panel’s rear using the sealant. The panel is left to dry, allowing the sealant and frame to set fully.  

After drying, the solar panel undergoes cleaning to remove chemical and sealant stains that might affect its performance.

Packaging of Solar Panels

Following this, the brand logo, technical specifications, and warranty card are affixed to the rear of the solar panel.  

At this point, the panels are fully prepared for packaging. They will be carefully packaged and dispatched to dealers and distributors who, in turn, provide them to consumers for utilisation in their solar projects.

Tests For Quality Assurance

Throughout the solar panel manufacturing process, a series of tests is meticulously executed to ensure the panels are defect-free and will deliver optimal performance throughout their operational life.  

Maintaining rigorous quality control in the production of solar cells is crucial because variations in numerous processes and factors can hugely impact the overall efficiency of the cells.   

The primary research objective is to discover methods to enhance the efficiency and longevity of each solar cell.  

Here is a list of the tests conducted during solar panel manufacturing:  

  • Quality Assessment of Solar Cells  
  • Evaluation of Solar Cell-Ribbon Bond Strength  
  • Examination of EVA Film Gel Content  
  • Testing the Adhesive Strength Between EVA Film and the Back Sheet  
  • Testing the Adhesive Strength Between EVA Film and Glass  
  • Evaluation of Glass Loading  
  • Electroluminescence Test (EL Test) Before Lamination  
  • Assessment of Aluminium Frame Anodising  
  • Test for Junction Box Wire Resistance  
  • Evaluation of Junction Box-Sealant Bonding  
  • Sun Simulator Test  
  • High Potential Test  
  • Final Electroluminescence Test

No one seems to understand Trump’s motivation here.  Did it have anything to do with the $400 million gift aircraft?

Does Qatar fear attack from Alberta or Saskatoon?

The Qataris say they need to be prepared to help achieve peace between the Israelis and the Palestinians.  I’m suspicious, though I’m no expert in military logistics.  We’re talking about a 6000-mile plane ride.

Trump’s Avalanche of Lies

Published

What? I’m confused.  “Trump’s Statement” of a few months was that “Gas prices are (present tense) under $2.”

It would have been interesting if one of the gaggle of reporters surrounding him could have asked the obvious question: “That’s great, sir, but can you name a single state in the union whose gas prices are under $2?

It would have been a tense moment, for sure, but don’t we have any self-respect?

Where Does Domestic Violence Come From?

Published

on

Over the past few months, and especially since the murder of Charlie Kirk, the right-wing news sources are telling us that most of the politically related violence is coming from the left, in particular from the left-wing “terrorist associations,” e.g., Antifa.

If you look at some coverage on the subject, however, you’ll learn that this is simple false.  Here’s a bit from a PBS piece:

PBS: Policymakers and the public need reliable evidence and actual data to understand the reality of politically motivated violence.

Craig: No, they don’t.  Are you serious?  Are we to believe that Donald Trump is sending federal troops to democratically-led cities based on “reliable evidence and actual data?” This is a sick joke.

PBS: From our research on extremism, it’s clear that the president’s and Miller’s assertions about political violence from the left are not based on actual facts.

Here’s more from the PBS article:

After the Sept. 10, 2025, assassination of conservative political activist Charlie Kirk, President Donald Trump claimed that radical leftist groups foment political violence in the U.S., and “they should be put in jail.”

“The radical left causes tremendous violence,” he said, asserting that “they seem to do it in a bigger way” than groups on the right.

Top presidential adviser Stephen Miller also weighed in after Kirk’s killing, saying that left-wing political organizations constitute “a vast domestic terror movement.”

“We are going to use every resource we have … throughout this government to identify, disrupt, dismantle and destroy these networks and make America safe again,” Miller said.

Political violence rising

The understanding of political violence is complicated by differences in definitions and the recent Department of Justice removal of an important government-sponsored study of domestic terrorists.

Political violence in the U.S. has risen in recent months and takes forms that go unrecognized. During the 2024 election cycle, nearly half of all states reported threats against election workers, including social media death threats, intimidation and doxing.

Kirk’s assassination illustrates the growing threat. The man charged with the murder, Tyler Robinson, allegedly planned the attack in writing and online.

This follows other politically motivated killings, including the June assassination of Democratic Minnesota state Rep. and former House Speaker Melissa Hortman and her husband.

These incidents reflect a normalization of political violence. Threats and violence are increasingly treated as acceptable for achieving political goals, posing serious risks to democracy and society.

Does Domestic Violence Come from the Left or the Right?
