Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation structures, in particular to a photovoltaic building material reinforcement structure for BIPV transformation. Background Art

[0002] Under the background of environmental awareness and energy conservation and emission reduction, the application of photovoltaic power generation devices has received more and more attention and has been put into use. Among them, the application of building integrated photovoltaic power generation (BIPV) has gradually been recognized by the industry and beyond.

[0003] BIPV is a way to integrate photovoltaic power generation systems into buildings. In short, it means embedding photovoltaic panels into the structure of a building, making it a part of the building. It can not only generate electricity but also have some architectural functions. This method can effectively utilize the roofs or exterior walls of industrial and commercial plants to convert light energy into electrical energy, which not only reduces the energy consumption of industrial and commercial plants, but also has significant aesthetics and can improve energy efficiency.

[0004] When we talk about BIPV renovation, we mean the renovation and optimization of existing buildings. With the help of BIPV technology, the building can make full use of photovoltaic technology to generate electricity and form a more energy-saving and environmentally friendly building. This renovation method is conducive to the full utilization of resources and the reduction of energy consumption.

[0005] However, there are some problems with the current BIPV renovation in the market. For example, during BIPV renovation, the installation frames of photovoltaic building materials are mainly welded together, and there are cases of weld cracks, which makes the structural reinforcement of photovoltaic building materials insufficient, which will have a certain impact on the service life of photovoltaic building materials. In view of this, we propose a photovoltaic building material reinforcement structure for BIPV renovation. Utility Model Content
