Step by Step Process of Making Solar Panels Are Made

1. Refining Raw Materials

Silicon is the second most available element on Earth, following oxygen. Silicon compounds are present in rocks, sand, clay, water, plants, and even certain animals. To purify silicon, it has to be heated to its boiling point at 1,410°C.

This high temperature helps with the extraction of cylindrical crystals from the molten silicon, ultimately creating single crystals. Especially, single crystals are formed by extracting cylindrical crystals from molten silicon.

Monocrystalline solar panel cells come from a solitary silicon crystal, similar to the concept of single origin coffee. On the other hand, polycrystalline solar panels are made up of a blend of silicon crystals, which result in a slightly reduced efficiency compared to their monocrystalline solar panels.

2. Solar Panel Manufacturing Process

The initial step in making of the solar panels includes the removal of impurities from silicon gotten from quartz sand. Following the purification process, the silicon is consolidated into solid masses that look like rocks. Subsequently, these masses are melted together, giving rise to cylindrical ingots.

Furthermore, a steel furnace with a cylindrical shape is employed to achieve the desired form. Throughout the manufacturing process, great attention is paid to making sure all atoms align in the desired orientation and structure.

In order to produce positive electrical polarity upon the silicon, boron is added into the process. Monocrystalline cells, which give a single silicon crystal, exhibit remarkable efficiency at a higher cost.

On the other hand, for polycrystalline cells, multiple silicon crystals are melted together. These panels bear a broken up, glass like appearance due to various silicon crystals. Once the resulting ingot has significantly cooled, it is carefully polished to yield flat surfaces.

3. Making Wafers During Solar Manufacturing

The stage that follows in the production of solar panels follows the creation of ingots. When producing wafers, the cylindrical ingot goes through a process of precision slicing into thin discs. This meticulous operation is carried out one step at a time, employing a cylindrical saw.

Alternatively, manufacturers can employ a multiwire saw, which enables the simultaneous cutting of multiple discs.

Note that the thin silicon material has a shinny quality that causes it to reflect light. Generally, to lower the reduction of sun rays, a slender film of anti glare coating is by great care applied onto the discs.

Typically, this coating is made up of titanium dioxide and silicon oxide, although alternative materials may also be used.

Applying the coating mentioned above involves heating it until the molecules reach a boiling point or making it to a spattering process.

In the case of spattering, manufacturers employ high voltage techniques to remove the molecules of the coating material, subsequently depositing them onto the silicon substrate.

Furthermore, the wafers can undergo additional polishing procedures to remove residual saw marks. However, certain manufacturers are opting to forgo these polishing steps, as the presence of saw marks can enhance overall efficiency.

5. Making Solar Panels from Solar Cells

Upon the completion of solar cell production, manufacturers ensures connections between them using metal connectors. Solar panels are formed by bringing together these solar cells into a matrix-like structure.

After the solar cells are all connected together, a thin glass casing is placed on the side facing the sun to enhance sun rays absorption. A highly durable polymer based material also creates the back sheet. This acts as a protective barrier against external elements such as water and soil, safeguarding the solar cells.

You can use a junction box when connecting the modules.

Subsequently, the manufacturer adds a frame, further fortifying the defense of the cells. The different parts are securely bound using ethylene-vinyl acetate (EVA), a resilient polymer adhesive. There are different solar panels for different functions, for example;

  • 48-cell panels: Optimal for small home roofs.
