Description

TECHNICAL FIELD

[0001] The utility model belongs to solar energy power generation technical field, especially relate to a fabricated solar roof structure. BACKGROUND

[0002] With the increasingly intensified global energy crisis, the energy-saving and environment-friendly concept has been widely popularized, and the utilization of solar energy has been very popular, among which the concept of photovoltaic roof has also begun to be widely constructed and implemented. However, in the current photovoltaic roof, the photovoltaic panel and the building roof are independent of each other, and when installing the photovoltaic panel, a metal support must be first built on the roof of the brick or concrete structure, and then the photovoltaic panel assembly is laid. The disadvantages of this structure are: 1. The roof is extremely heavy, so that a part of the roof cannot be constructed at all; 2. The windproof performance is very weak and difficult to resist strong typhoons; in addition, the construction of this structure is very inconvenient, the construction speed is slow, and the construction cost is high.

[0003] Especially in the field of sewage treatment, in order to avoid the overflow of foul-smelling gas, a glass fiber reinforced plastic (FRP) roof needs to be added to seal and collect the gas. The sewage equipment in the sewage treatment plant usually occupies a large area, so the glass fiber reinforced plastic cover has a large coverage area. If this part of solar energy can be utilized, the operation state of the sewage plant with high energy consumption can be improved.

[0004] The key component of photovoltaic power generation technology is solar cell, and the current photovoltaic power generation cell is based on semiconductor technology. It can be further divided into two types, one is the traditional and mature crystalline silicon cell, and the other is the new generation of thin film cell.

[0005] The crystalline silicon cell is made of high-purity crystalline silicon rod as raw material. Since it has the highest photoelectric conversion efficiency and mature technology, it has been widely used in sewage treatment plants. The traditional installation method of crystalline silicon cell is to set horizontal or vertical supports on the glass fiber reinforced plastic cover, and then install the cell panel on the supports. This method has the following problems: (1) After installing the cell panel supports on the roof, it is difficult to realize the movable installation with the building structure. When the sewage treatment equipment needs to be overhauled, the fixed roof and support are not convenient to disassemble, which affects the overhaul efficiency; (2) The sewage plant requires high corrosion resistance of the support due to the production of hydrogen sulfide and other acidic corrosive gases in the sewage treatment process, which increases the installation cost of the photovoltaic power generation panel; (3) When the sewage treatment pool is fully supported, there is a risk of collapse, and in order to ensure the structure bearing capacity, the space utilization rate of the sewage treatment pool is low and the power generation capacity is weak.

[0006] The thin-film battery belongs to amorphous silicon structure, and the biggest difference from the crystalline silicon battery is that the thickness is less than 1 micron, which is less than one percent of the thickness of the crystalline silicon battery, so that the manufacturing cost is greatly reduced. The thin-film battery has the advantages of easy large-area spreading and good weak light performance, but the photoelectric conversion efficiency is low. In the prior art, the thin-film battery is attached to the outer surface of the glass steel, so that it is suitable for the environment of the sewage tank plant, which can improve the limitation of the application of the crystalline silicon battery photovoltaic panel in the sewage plant, but the significant disadvantage is that the power generation efficiency is low, and since it is directly attached to the outer surface of the cover plate, it is not conducive to heat dissipation of the panel, and the panel is easy to burn.

[0007] Therefore, there is an urgent need for a reliable and safe solar roof structure with high photoelectric conversion efficiency. Content of the utility model
