Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a photovoltaic protection frame resistant to wind and snow in winter. Background Art

[0002] Photovoltaic panels, also known as solar panels, are devices that convert sunlight into electricity. Their principle is based on the photoelectric effect. When photons strike the semiconductor material (such as silicon) in a photovoltaic panel, the energy of the photons is absorbed by the semiconductor, causing electrons to jump from the valence band to the conduction band, thereby generating an electric current.

[0003] In real life, most photovoltaic panels are tilted and have a certain height. However, when encountering bad weather, such as strong winds, the tilted setting of the photovoltaic panels will increase the contact area between the photovoltaic panels and the wind. Strong winds may blow the photovoltaic panels up and cause damage. In addition, in snowy weather, if no protection is taken, snow will accumulate on the photovoltaic panels and even freeze, which may affect the subsequent use effect. Summary of the Invention
