Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a photovoltaic bracket on a sloped roof. Background Art

[0002] With the popularization of solar photovoltaic power generation, solar photovoltaic panels are installed on roofs in large quantities. Since photovoltaic panels need to face the sun and maintain a suitable angle to ensure the efficiency of photovoltaic power generation, measurements are usually taken on the roof before the photovoltaic bracket is installed. The photovoltaic bracket is customized based on the measurement data to ensure that the photovoltaic panels can maintain a suitable angle after installation to generate photovoltaic power more effectively.

[0003] At present, photovoltaic brackets are mainly fixed by connecting the bracket base to the roof. Some houses use double-slope sloping roofs with steep roof slopes and tiles are laid on the roof. The existing photovoltaic bracket structure is fixed and single. When the installation position is limited and lateral adjustment is required, it can only be achieved by changing the position of the bracket base. In addition, the height of the support arm cannot be adjusted, resulting in poor flexibility of the photovoltaic bracket, making the photovoltaic bracket less adaptable to the roofs of different houses, limiting the scope of use of the photovoltaic bracket.
