Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to an adjustable photovoltaic bracket for distributed photovoltaic power generation panels. Background Art

[0002] Photovoltaic system, also known as solar photovoltaic power generation system, is a new power generation technology that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. During the installation process, photovoltaic components need to be reliably fixed using dedicated photovoltaic brackets to ensure stable operation of the system.

[0003] Although existing photovoltaic brackets can adjust the angle of photovoltaic panels, when used in cold areas in winter, when snow accumulates on the surface of the photovoltaic panels, the uneven distribution of the weight of the snow will produce a lateral thrust on the photovoltaic panels, causing the center of the photovoltaic panels to shift, changing the originally set tilt angle of the photovoltaic panels, resulting in the inability to work according to the predetermined angle adjustment plan, and reducing the amount of solar radiation received in some photovoltaic panel areas. Therefore, we propose an adjustable photovoltaic bracket for distributed photovoltaic power generation panels. Summary of the Invention
