How Does Solar Panel Manufacturing Work?
Raw Materials.
The first step in solar panel manufacturing is the collection of raw materials. The main components of a solar panel are silicon, aluminum, glass, and plastic. Silicon is the most important material because it is used to make solar cells. .
Formation of Solar Cells.
In order to create solar cells, the silicon is purified and melted. Once the purified silicon is molten, it’s formed into long cylindrical rods. Once the rods cool and become solid, they are sliced into thin wafers using a diamond saw. These wafers are then cleaned and coated with a layer of phosphorous to create a negatively charged layer on one side. .
Assembly of Solar Panels.
After the formation of solar cells, the assembly of the solar panels begins. First, a frame is created using aluminum. The frame provides support to the panel and protects it from weather and physical damage or degradation. Both the positive and negatively charged solar cells are interconnected using silver. This is where the energy conversion process begins. .
Encapsulation.
The next step is the most important in the manufacturing process. It’s where the encapsulation of the panel is done to protect it from moisture, dust and other elements that may interfere with its longevity. The solar cells and wiring are placed between two layers of plastic or glass, which is sealed with a special adhesive.
Quality Check.
After encapsulation, a quality check is done. Solar panels go through numerous checks to ensure that every component is working perfectly. The final inspection ensures that the panel produces the power output it's designed for and that there are no damages on the surface layer.
Final Packaging.
After the quality check is done, the manufacturing process comes to an end. The solar panels are packaged carefully to avoid any kind of damage or degradation. The panels are packed in groups, and the quantity of panels per group depends on its size. The final packaging is done so that the panels are ready for installation.
Conclusion.
In conclusion, the manufacturing process of solar panels is a complex one, but it’s important to remember that every step is vital to ensure that the panels are of high quality and efficient. From the raw materials to the packaging, every step is done with precision and care.
