Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic module installation, in particular to a BIPV photovoltaic module with easy installation. Background Art

[0002] BIPV generally refers to building integrated photovoltaics, which is a new concept for applying solar power generation. Simply put, it is to install a solar photovoltaic power generation array on the outer surface of the building envelope structure to provide electricity. Most of the solar photovoltaic roofs in the BIPV photovoltaic module system are composed of multiple photovoltaic modules spliced together, but the splicing structure of the existing solar photovoltaic roofs is relatively simple.

[0003] For example, a Chinese patent document with the publication number CN216672909U discloses a BIPV photovoltaic module system, which records that "each photovoltaic module is composed of multiple photovoltaic panels spliced together. At one end of each purlin close to the photovoltaic module, a first platform frame and a second platform frame are arranged. The top surface of the first platform frame is higher than the top surface of the second platform frame. First, tilt one end of the photovoltaic panel at a certain angle and connect it to the first platform frame on the first purlin, and then gradually flatten the photovoltaic panel so that the other end of the photovoltaic panel is connected to the second platform frame of the adjacent purlin. Because the heights of the positions where each purlin is located increase in sequence, multiple photovoltaic modules are inclined at a certain angle, and a water guide groove is arranged on each photovoltaic panel". When it rains, rainwater flows down along the photovoltaic panel, and the leaked rainwater is discharged through the water guide groove, so that the BIPV photovoltaic module system has better waterproof performance.

[0004] However, combined with the existing technology, there are still the following defects or problems: the above BIPV photovoltaic module system is mainly suitable for back installation. At present, BIPV photovoltaic modules are mostly used on the top of factory buildings, and the height from the ground is relatively large. The back installation method requires workers to install a scaffold close to the top of the factory building, then lift the module above the purlin, and then fasten it from below the purlin; and back installation requires high installation accuracy, which is not conducive to rapid construction, and the installation accuracy in front installation is lower than that in back installation. Provide a BIPV photovoltaic module with easy installation to solve the problem that the BIPV is fastened to the purlin during front installation in the existing solar photovoltaic roof in the prior art. Summary of the Utility Model
