Solar Panel Manufacturing Process Material and Steps
In solar power equipment in Pakistan, in a solar panel, a solar cell set is contained whose functioning is to convert the sun’s light into the energy of electricity. In solar panel manufacturing primary material is silicon. Many of the solar panels that you see are polycrystalline or monocrystalline. The manufacturing process of solar panels determines their efficiency.
As people switch to solar panel energy, it’s going to be very good to know a few important things about how solar panels are manufactured.
Solar panel manufacturing material and steps
In this article, we will look at a few things that you need to know about manufacturing solar panels.
The raw material of solar panel manufacturing
One of the first and crucial components that are required to make solar cells is pure silicon. However, silicon is not going to be pure in its natural state. It’s derived from quartz sent in a furnace requiring greatly high temperatures. This silicon is also used by water filter plant supplier in their products.
The natural sand of the beach is one of the main components in manufacturing pure silicon. Though in the world it is one of the abundant resources, the pure silicon getting process comes at a cost and requires a lot of great energy.
Solar panel process of manufacturing
In solar panel manufacturing, the first process is silicon purifying from quartz sand. Once the silicon is purified totally, then it is collected into solid rocks. These rocks are then together greatly molten, forming cylindrical ingots. A cylindrical furnace and steel are utilized to achieve the desired shape. When manufacturing is underway, there is a keen attention to having all aligned atoms in desired structure and orientation.
In order to give the silicon positive electrical polarity, boron is also included in the process. To make monocrystalline cells, the manufacturing only goes to use one silicon crystal. As a result, such solar panels have great and high efficiency. However, they come at a higher cost than others.
For polycrystalline cells, the manufacturer’s several silicon melt crystals together. These panels have the appearance of shattering glass derived from the various silicon crystals. Once the ingot is cooled, it is polished and shined to leave flat sides.
Making of wafers
In the manufacturing of solar panels the next step after making ingots. To make wafers, the cylindrical ingot is sliced thinly into thin disks. Using a cylindrical saw, It’s done one at a time. Material manufacturers also use a multi-wire saw to cut many counts at a time.
The wafers can be further polished in order to remove saw marks. However, some of the manufacturers are choosing in order to skip these steps as the saw marks help to increase efficiency.
Making of solar cells
Follow manufacturers several steps to convert the silicon wafers into usable solar cells. They treat one of each wafer and add conductors of metal on the surface. The addition of conductors results in a grid-like appearance of a matrix on the surface. They ensure sunlight conversion into electricity.
Solar cells to solar panels
Once the solar cells are made, the manufacturers connect them using the connectors of metal. Solar panels are solar cells in a matrix-like structure. The solar panel market standard is:
- 48 cells of panels – is ideal for small residential roofs.
- 60-cell panels – it is the standard size.
- 72-cell panels – it’s suitable for large-scale installations.
Solar panel testing
Once the solar manufacturing is completed, so, in the end, testing is done to ensure it meets the expected performance.
Generators for sale in Pakistan, are also made of great kinds of electricity for Pakistan usage. Solar panels are playing one of the great roles in the manufacturing of electricity all over the world.
