In the production of solar panels, cells need to be encapsulated in glass or polymer films to maintain their stability and functionality. In this process, a vacuum pump needs to be used to extract the air to ensure the vacuum between the cell sheet and the packaging material to improve its photoelectric conversion efficiency. Vacuum pumps are used to extract air or working fluid to form high-speed airflow or steam to drive turbines to generate electricity. This can improve solar energy utilization and power generation efficiency.
