Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel material film application technology, specifically to a film application and bubble removal device and method. Background Technology

[0002] A photovoltaic (PV) panel, also known as a solar panel, is a device that converts solar energy into electrical energy. It consists of multiple photovoltaic cells, typically thin sheets made of semiconductor materials such as silicon. When sunlight shines on a PV panel, photons are absorbed by the photovoltaic cells, exciting electrons and creating an electric current. This current is then fed into an inverter through the PV panel's output terminals, ultimately being converted into alternating current for use by the power grid. PV panels have a wide range of applications, including residential, commercial, and industrial settings.

[0003] After production, photovoltaic (PV) panels require a film coating process. This coating offers several advantages: 1. UV protection: PV panel surfaces are exposed to ultraviolet (UV) radiation, and the film helps prevent UV damage. 2. Reduced light reflection: PV panel surfaces can reflect light, leading to energy loss. The film reduces reflectivity. 3. Increased light transmittance: The film makes the surface smoother, increasing light transmittance. However, during the coating process, the film is prone to misalignment and air bubbles.
