Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, and more specifically, to a support for photovoltaic roofs. Background Art

[0002] Photovoltaic panels are the core components of solar photovoltaic power generation systems. They convert sunlight directly into electrical energy through the photoelectric effect. Photovoltaic panels are mainly composed of photovoltaic cells, which are semiconductor devices that use the photoelectric effect to convert light energy into electrical energy. When sunlight shines on the surface of photovoltaic cells, photons excite electrons in the semiconductor material, thereby generating current in the conductor. The mounting frame is a support system used to install solar photovoltaic panels on the roof of a building. Its design and installation quality are directly related to the stability, safety and efficiency of the solar photovoltaic system.

[0003] In the existing technology, the structure of the support is relatively fixed, and usually bolts or other fasteners are needed to firmly connect it to the roof. The size and shape of the support may not completely match the shape and angle of the roof, resulting in some gaps or imperfections when fitting with the roof, affecting the installation stability of the support. At the same time, the support angles of some supports are fixed, which will limit the optimal angle adjustment of the photovoltaic panel in different seasons or at different latitudes, thereby affecting the power generation efficiency of the photovoltaic system. Finally, the connection between the photovoltaic panel and the support is inconvenient, reducing the convenience of installation and disassembly of the photovoltaic panel. Utility Model Content
