Solar panels are the systems that provide solar energy-based electricity for different residential and commercial applications. The average life expectancy of solar panels is 30 years. The key raw materials required to manufacture solar panels include raw polysilicon, silicon wafers, ingots and bricks, solar backsheets, junction boxes, PV cells, silver paste, aluminum paste, and solar material solutions. Silicon is obtained from quartz in the solid form and melted at a very high temperature to form ingots. These ingots are then sliced into thin disks, known as wafers, which are then treated, with the addition of metal conductors. Finally, solar cells are put together and a glass is added on the front side to form a panel or module.
