Description

Technical Field

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

[0002] BIPV stands for Building Integrated PV, which is photovoltaic building integration. PV stands for Photovoltaic. BIPV technology is an innovative technology that integrates solar power generation (photovoltaic) products into buildings, without the need for additional land, while also saving the cost of supporting structures. The advantage of this technology is not only that it can provide sufficient area for the photovoltaic system, but also that it can meet the internal electricity demand of the building while outputting electricity to the grid according to specific conditions, alleviating the pressure of electricity demand and bringing huge social benefits. The journal "Industrial Buildings" Issue 1, 2023 "Design and Application of Photovoltaic Building Integration (BIPV)" pointed out: With the help of the scientific and technological level of the new era, photovoltaic buildings have broad development prospects and can provide support for the development of my country's energy conservation and emission reduction.

[0003] Photovoltaic brackets are brackets used to place, install, and fix photovoltaic panels in photovoltaic systems. The materials used are generally aluminum alloy, carbon steel, and stainless steel. Existing photovoltaic brackets are all rail-type brackets, which require a lot of materials and have high installation costs. If a photovoltaic system is installed on a color steel tile roof, it is necessary to drill holes in the color steel tile roof first, and then install the rail-type bracket. Drilling and installation is time-consuming and labor-intensive, increasing labor costs; at the same time, it damages the color steel plate. If the drilling position is not waterproofed well, it is easy to cause the building roof to leak and is not convenient for maintenance. In summary, the existing industrial and commercial BIPV must destroy the color steel tiles and use self-tapping screws or adhesives to fix the structure. Either the fixation is not firm or the color steel tiles are damaged, resulting in poor roof waterproofing performance. Summary of the invention
