Manufacturing Solar Panels: Processes and Materials

The journey to create manufacturing solar panels showcases the marvels of engineering and technology. It begins with crystalline silicon, the key material for most PV modules. The creation of polysilicon, crucial for solar cell production, involves reactions with volatile gases. This includes a mix of metallurgical-grade silicon, hydrogen, and chlorine.

Making these materials into working solar panels involves several steps. First, silicon ingots are cut into thin wafers. They use diamond-coated wire saws for this. Another method is kerfless wafer production. It pulls layers directly from a silicon molten bath, showing the industry’s efforts to reduce waste.

Fenice Energy, a renewable energy leader, follows these steps to make solar panels. They use aluminum alloy frames known for their durability. Also, EVA packaging adhesive film is crucial. It seals and protects the solar cells from environmental damage.

The racks that hold these panels are built to last. Ground systems use steel with protective coatings to prevent rust. In cities, commercial buildings often have heavy-duty steel racks on their roofs.

Power electronics are key for turning the captured sunlight into usable energy. They use advanced robotics to assemble circuit boards. These boards are filled with essential parts like transistors and capacitors.

China has made a huge $50 billion investment in solar panel production. This move is shaping the future of solar technology, making up over 80% of the world’s solar panel production stages. In 2021, their export value reached a staggering $30 billion.

But this booming industry has its challenges, especially with its environmental impact. Currently, over 60% of the power used in solar PV manufacturing comes from coal. This fact highlights the industry’s growth to $40 billion in 2021 and its goal for China to dominate up to 95% of polysilicon, ingot, and wafer production by 2025.

In response to these challenges, Europe is aiming to make solar PV manufacturing greener. The goal is to use less carbon-intensive energy sources for production. By 2030, the demand for critical minerals could exceed 30% of global silver production. This aligns with Fenice Energy’s goal to produce sustainable, high-performance solar modules.
