[0002] Photovoltaic building roof refers to the installation of solar panel power generation systems on the roof, which converts solar energy into electrical energy and converts direct current into alternating current through an inverter to provide electricity for homes or businesses. Photovoltaic building roofs can reduce energy costs and save energy expenditures by generating electricity, while improving the sustainability of houses and reducing carbon footprints, making houses more attractive.

[0003] When installing photovoltaic panels, in order to ensure the stability of the installation, frame components are reinforced around the photovoltaic panels to prevent the photovoltaic panels from being affected by wind and affecting their stability. However, most of the existing frame components wrap the edges of the photovoltaic panels, resulting in the frame components being higher than the photovoltaic panels. This installation method makes it difficult for water to drain out in rainy and snowy weather.
