Problems solved by technology

[0004] At present, the standard photovoltaic modules used in the market do not take into account the structure of the building from the design point of view. In actual use, it is found that the traditional modules are not practical due to problems such as fire performance, waterproof structure, indoor moisture resistance, ventilation and heat dissipation, and building insulation. Large-scale application in building integration system

The specific manifestations are as follows: 1) Traditional photovoltaic modules are widely used in buildings, and most of them use flat glass, which will cause large-scale reflections and cause visual pollution; at the same time, due to the structure and physical characteristics of photovoltaic cells, the structural size is fixed, showing a blue color in arrangement and combination Matrix color blocks, single color form, inconsistent with the overall design style of the building, poor decorative effect for the display of urban culture

2) With the diversification of building shape design, there are more and more curved shapes, which requires building materials to be able to change shapes continuously to meet the needs of buildings; however, affected by the fragility of silicon materials in crystalline silicon photovoltaic modules, photovoltaic modules can only Made into a flat plate, it cannot be combined with building materials

3) Traditional photovoltaic modules adopt a composite packaging structure of glass + photovoltaic cells + plastic backplane. The use of plastic backplane makes conventional photovoltaic products only meet the standard of fire protection class c. As a roof or wall enclosure structure alone, there are certain potential safety hazards; therefore, the installation of conventional photovoltaic modules in buildings increases the load on the roof or walls, which has structural hidden dangers and is likely to cause fire risks

4) Traditional photovoltaic modules are surrounded by aluminum alloy frames. When applied to building integration, a waterproof structure needs to be added to ensure the waterproofing of the roof or wall, which increases the cost. The existing photovoltaic module installation structure and waterproof structure are not compatible. Not designed as a whole, and most of them are rigidly connected. With the settlement of the building, it will cause local structural deformation and waterproof failure

5) Traditional photovoltaic modules are used in building integrated photovoltaics. Unlike open ground power stations, the back is close to the roof or wall and does not form a continuous heat dissipation channel. While generating electricity, the heat gathers on the back of the photovoltaic module, resulting in local high temperature. Above 60°C, the performance of photovoltaic modules will decline at high temperatures, and the loss of power generation will also cause the roof or wall to transfer heat to the room, increasing the building's electricity consumption

6) Existing photovoltaic modules are applied to building integrated photovoltaics. It is necessary to design and install metal frames, and use bolts and special installation fixture structures to fasten photovoltaic modules to metal frames; there are many types of structural components and cumbersome steps, especially in roof and When installing on the wall, multiple people are required to cooperate, and the installation efficiency is not high

7) Photovoltaic modules, insulation layers and installation structures are all scattered parts, without a unified design, requiring on-site construction and assembly, the work efficiency is not high, and different types of work are required to be constructed in stages, the cycle is long, and there is a waste of materials, further increasing building construction cost
