Invest in Solar Panel Production
Take the first step towards starting your solar module manufacturing business. Learn everything from the basics to the effects of location, the pros and cons, and the potential of solar manufacturing in emerging markets.
The manufacturing of solar panels involves several steps, including the production of solar cells, connecting the cells, and then adding materials including glass, a back sheet, and a frame to form a solar panel.
The initial stage in manufacturing a module is the production of solar cells. This process involves the following steps:
Polysilicon Production: The first step is the production of polysilicon, which is the primary material used to create solar cells. Polysilicon is produced by melting silicon and then allowing it to cool and solidify into a block.
Wafer Production: Once the polysilicon block is created, it is sliced into thin wafers with a diamond saw.
Cell Production: The silicon wafers are then coated with a thin layer of anti-reflective material and a thin layer of conductive material. The conductive material is usually made of silver and helps to create an electrical current when the cell is exposed to sunlight.
Module Assembly: The solar cells are then assembled into modules. This involves connecting the cells with wires. The cells are connected in series or parallel to create the desired voltage and current output.
Panel Assembly: Finally a frame is added to give the module stability. The cells are protected from exposure or impact with a back sheet at the back and glass in the front.
Fortunately, for our purposes, the only stages we need to be concerned about are the module assembly and panel assembly.
