Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of photovoltaic insulation board, specifically relates to a photovoltaic insulation integrated board. BACKGROUND

[0002] Under the trend of building energy saving and renewable energy utilization, photovoltaic insulation integrated board emerges as the times require. It organically combines photovoltaic power generation function and building insulation function and is a new type of building material. Photovoltaic insulation integrated board is mainly composed of photovoltaic glass, insulation layer and other auxiliary components. Among them, photovoltaic glass is the core component to realize photovoltaic power generation, which can convert solar energy into electric energy; the insulation layer is responsible for reducing the heat transfer between the inside and outside of the building, plays the role of insulation and improves the energy utilization efficiency of the building. The integrated design makes the building meet the basic enclosure function while realizing the self-sufficiency of clean energy, conforms to the concept of green building and sustainable development, and has broad application prospects in the field of modern buildings.

[0003] However, the traditional photovoltaic insulation integrated board has many drawbacks in practical application. In the installation process, the traditional process adopts the way of on-site layered installation. This installation method needs to install photovoltaic glass, insulation board and other components in sequence on the construction site, and the process is complicated. The installation of each component needs accurate positioning and operation, and the construction process is easily affected by weather, construction personnel's technical level and other factors, resulting in low construction efficiency and thus greatly prolonging the construction period. For example, in some large building projects, it may take months or even longer to install photovoltaic insulation integrated board using traditional installation process, which undoubtedly increases the time cost and management cost of the building project. From the economic cost point of view, the traditional installation method not only consumes a lot of manpower and time, but also leads to high construction cost. On-site layered installation needs to invest more construction personnel and construction equipment, and the labor cost and equipment rental cost increase significantly. In addition, due to the long construction period, the indirect costs of the project such as site rental cost and management cost also increase accordingly. These additional costs make the traditional photovoltaic insulation integrated board at a disadvantage in market competition, limiting its large-scale popularization and application.

[0024] Improve construction efficiency and reduce cost: the photovoltaic glass and the insulation plate are integrally and modularly produced, and are assembled and installed on site. In the production link of the factory, the components are assembled after standardized production and strict quality detection, forming a modular integrated plate. After arriving at the construction site, the integrated plate is directly assembled and installed, greatly reducing the process and time of on-site construction.

[0025] Enhance power generation capacity and achieve energy saving and carbon reduction: the integrated design optimizes the working environment of the photovoltaic glass, reducing the influence of heat on the photoelectric conversion efficiency. Through the design of the heat dissipation channel and the reasonable layout of the components, the photovoltaic glass can work at a relatively low temperature, thereby improving the photoelectric conversion efficiency and increasing the power generation capacity. At the same time, as a clean energy, photovoltaic power generation can meet the electricity demand of the building itself, reduce the dependence on traditional fossil energy, and reduce carbon emissions.

[0026] Enhance structural stability: the special wavy, concave-convex or flat structure of the metal plate significantly increases the rigidity compared with the flat design of the original curtain wall layer. This structure can better withstand external loads such as wind force and earthquake force, reducing the deformation and damage risk of the integrated plate during use. At the same time, the insulation material is installed by pasting and mechanical fixing, which is more firm than the original way of pasting with adhesive. Even under long-term vibration or external force, the insulation material is not easy to fall off, ensuring the integrity and stability of the insulation layer, thereby improving the overall structural performance of the integrated plate and prolonging the service life.
