Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic buildings, in particular to a photovoltaic building integrated roof. Background Art

[0002] Building-integrated photovoltaics (BIPV) is a technology that integrates solar power generation products into the building envelope. By installing PV panels on a building's roof, facade, or awning, the building not only fulfills its structural functions but also becomes self-sufficient, improving energy efficiency. This technology not only enhances the building's aesthetics and practicality, but also effectively reduces carbon emissions, meeting the requirements of sustainable development.

[0003] Its application number "202322250373.1" discloses an integrated waterproof roof for photovoltaic buildings, which includes a support frame, solar panels, a slide, a tarpaulin traction device, a tarpaulin storage device, and a top plate. A plurality of solar panels are fixedly connected to the front of the support frame at equal intervals. The two slides are respectively opened on both sides of the support frame. The two tarpaulin traction devices are slidably connected in the two slides. The tarpaulin storage device is fixedly connected to the rear inside the support frame. The top plate is fixedly connected to the top of the support frame. The device is designed to address the non-waterproof shortcomings of existing photovoltaic building roofs, and the device structure is designed to provide rain protection for the solar panels in rainy environments, thereby increasing the service life of the solar panels.

[0004] However, the above method also has the following defects: rainwater flushing actually helps to clean the dust and dirt on the surface of the photovoltaic panels. Keeping the photovoltaic panels clean is crucial to their long-term efficiency. Long-term use of tarpaulin covering may reduce the chance of natural cleaning by rainwater, causing dust to accumulate on the surface of the photovoltaic panels, thereby affecting the power generation efficiency. In addition, in order to achieve the waterproof function, it is necessary to add a tarpaulin traction device and a tarpaulin storage device, which not only increases the complexity of the system, but also increases the construction cost. The maintenance of these additional equipment also requires additional costs. Utility Model Content
