Where are Sunpower solar panels made

While solar panels are capable of generating solar energy from the sun, they are relatively simple to produce when built professionally in a well-run factory. Solar cells, silicon, metal, and glass are the primary components of a solar panel. After assembling all of these components, a solar panel capable of generating renewable energy is formed.

Permit us to walk you through the process of how and where Sunpower solar panels are manufactured.

How and where Sunpower solar panels are made

Step-1

  • Traditionally, solar cells were made of P-type silicon. A p-type silicon cell has a positively charged base, meaning the bottom layer contains boron and phosphorus.
  • The n-type cell, on the other hand, has phosphorus as its foundation. Mainly, n-type cells are more efficient and do not suffer from light-induced degradation, or output reduction, when exposed to intense sunlight.
  • It is heated and then combined with gallium or boron to make silicon ingots. Then phosphorus is added to the silicon, giving it its electrical properties along with gallium or boron.
  • Once chopped into thin sheets, the silicon ingot is anti-reflective coated, capturing sunlight instead of reflecting it away from the panels. Thin lines are then carved into the cells to catch and transport the current.
  • When the photons from the sun are absorbed, electrons travel within the solar cells to create energy.

Polycrystalline solar panels are made up of several silicon fragments fused together to form one big sheet.

Step-2

  • Solder solar cells together to create a solar panel; typically, 60 or 72 solar cells make up a solar panel.

Step 3

  • Install the back sheet that protects the solar cells’ bottoms.

Step-4

  • Integrate a glass front. This permits light to reach the solar cells while also providing a protective coating.

Step-5

  • Silicone-seal a metal frame around the panel to bind all of the layers together.

Step-6

  • Install the junction box that protects the electrical cables on the solar panel from harm.

Step-7

  • Before delivering a solar panel for usage, inspect it for quality and robustness.

After passing quality control, the solar panels are ready to be shipped and installed on homes or solar farms. While the production process for all types of solar panels is quite similar, there are a few distinct types of solar panels, each with its own set of advantages.

Final Words

We do not recommend making your own solar panels. It is best to rely on professionally built solar technology because they are built with rigorous standards and tested for durability. Solar panels are one of the best energy sources for reducing carbon dioxide from fossil fuels so adding them to your home is a great way to help the environment.
