Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and particularly relates to a photovoltaic bracket for building exterior walls. Background Technique

[0002] A photovoltaic bracket, also known as a solar panel bracket, is a bracket system specifically used for installing and supporting solar panels. In the application of building exterior walls, the photovoltaic bracket not only needs to firmly fix the solar panels, but also needs to consider the overall aesthetics, structural safety, and power generation efficiency of the photovoltaic system of the building.

[0003] The existing photovoltaic brackets are often fixed. When installing photovoltaic panels, they are often fixed through the photovoltaic brackets. In order to consider the changes in seasons throughout the year, the irradiation angles of the sun are different. If the inclination angles of all photovoltaic brackets cannot be adjusted according to the different incident angles of sunlight, the annual power generation efficiency of the photovoltaic will be relatively reduced a lot. The fixed photovoltaic brackets cannot adjust the angles of the photovoltaic modules, and thus some power generation will be lost.

[0004] For this reason, a photovoltaic bracket for building exterior walls is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a photovoltaic bracket for building exterior walls to solve the problems raised in the above background technique.
