Technical Field

Background
Wind energy, solar energy, ocean energy, geothermal energy and the like are new energy sources which can be utilized by people at present, production places of the wind energy, the solar energy, the ocean energy, the geothermal energy and the like are all arranged in suburbs, deserts or oceans with rare smoke and low energy consumption, and the utilization of the new energy sources is rarely seen in cities with concentrated population and high energy consumption. On the one hand, the new energy is not distributed in a centralized way, such as the centralized distribution area of wind energy, ocean energy and geothermal energy is not suitable for human residence; on the other hand, the new energy is not fully and reasonably utilized, for example, the solar energy is widely distributed, and a large amount of available solar energy is available in cities with large population density. Solar energy is the most extensive, universal and distributive clean energy technology in the current renewable energy technology.
At present, the main mode of combining building and solar energy is Building Integrated Photovoltaic (BIPV), but the conventional BIPV adopts a dual-glass assembly, namely a component material consisting of a glass front plate, an intermediate power generation circuit layer and a glass back plate, which is also called a dual-glass assembly. The products of such glass master materials have the following disadvantages:
(1) the adopted toughened glass cannot be subjected to secondary processing;
(2) the dual-glass assembly essentially belongs to laminated toughened glass, has poor connection performance with an external maintenance structure of a building, particularly a wall surface and a roof surface, and can be matched and installed with the external maintenance structure of the building only by additionally adding a large number of accessories and installation components; the connecting gap between the components is a flat gap, and the waterproof glue is required to be filled to block rainwater;
(3) the weight of unit area is large, so that the self weight of the building is increased, and the load and the cost of the building structure are increased;
(4) the rigidity is fragile, only a plane can be made, the curved surface is difficult to be made, and the requirements of the building appearance on the curved surface and lines are difficult to meet;
(5) the safety and the fire resistance are poor, and the self-explosion is easy to happen particularly in fire and high temperature in summer;
(6) the back surface can not be directly pasted with the heat-insulating material, and the joint is sealed by the waterproof glue, so that the waterproof performance and the heat-insulating performance of the installed roof or wall surface are poorer than those of the existing conventional building material, and the weather resistance is poor;
(7) the application range is narrow, and the method is mostly used for scenes such as building roof pavilion rainsheds, parking sheds, vertical surface railing members, window sunshade members and the like.
Therefore, building material members typified by conventional dual glass assemblies are difficult to popularize and use.
The existing color steel tile roofs of a plurality of current workshops can not have the same life cycle as buildings, and especially in southern coastal cities, the service lives of the color steel tiles can be as long as 7-10 years. With the development of BIPV, BIPV has had great advances and advantages as a roofing material. However, when the conventional photovoltaic product is used for constructing damaged color steel tile roofs, the conditions are harsh, the original roofs sometimes need to be dismantled, and even local civil buildings are pushed to be heavy. Therefore, the photovoltaic product laid on the existing roof has high operation difficulty, high economic cost and poor combination degree with the building roof.
