Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, and more specifically to a solar photovoltaic panel for a color steel tile roof. Background Art

[0002] With the rapid development of society, people are increasingly aware of the limitations of non-renewable energy such as oil, and are constantly trying to develop new energy to cope with the upcoming energy crisis. At the same time, oil, coal and other energy sources will inevitably pollute the environment during use. As people's awareness of environmental protection increases, the requirements for clean energy are also getting higher and higher. Solar energy, as an efficient, pollution-free renewable resource, has gradually been used by all walks of life. With the improvement of environmental protection awareness, the development of photovoltaic power generation has been steadily advancing.

[0003] The current photovoltaic panels or solar modules are all encapsulated and sealed with glass and aluminum frames, resulting in a weight of more than 10 kilograms per square meter. Therefore, the traditional photovoltaic power generation system is very heavy and requires a special fixing frame when installed on the roof. In other words, when the traditional photovoltaic power generation system is installed on the roof, a special support structure is required to support the photovoltaic power generation system. Moreover, when the traditional photovoltaic power generation system is installed on the roof, it will greatly increase the weight of the roof and the wind load. In many cases, the number of components of the photovoltaic power generation system to generate the required electricity will exceed the structural upper limit that the roof can withstand, thereby hindering the installation of the required photovoltaic power generation system.

[0004] Photovoltaic power generation technology has been accompanied by the development of lightweighting. Usually, solar photovoltaic panels are connected to the color steel tile roofs of industrial and commercial plants. However, the current mainstream color steel tile panels have the disadvantages of simple structure and short service life. The treatment of the joints between photovoltaic panels and color steel tiles is relatively troublesome, which affects the service life of solar panels during use.

[0005] Therefore, how to provide a solar photovoltaic panel for color steel tile roofs to solve the problem of short service life of conventional color steel tile panels is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A solar photovoltaic panel for a color steel tile roof:

[0009] The solar photovoltaic panel includes a front glass plate, a battery string, an insulating plate and an aluminum-magnesium-manganese bottom plate from top to bottom. The front glass plate and the battery string, the battery string and the insulating plate, and the insulating plate and the aluminum-magnesium-manganese bottom plate are all connected through a POE film.

[0010] The beneficial effect of the above technical solution is that the aluminum-magnesium-manganese plate is used as the backplane of the solar photovoltaic panel. The aluminum-magnesium-manganese plate is a very cost-effective roofing and exterior wall material, which has the characteristics of light weight, high strength, corrosion resistance, diverse surface treatment, beautiful appearance, good plasticity, easy processing, good conductivity, easy installation and environmental protection. It can be well connected and fixed to the color steel tile roof of industrial and commercial factories; the front plate of the photovoltaic panel uses glass, which has extremely high light transmittance, and a layer of insulating board is added between the battery string and the roof color steel plate, which can effectively insulate and prevent power loss.

[0011] Preferably, the battery string is a polycrystalline silicon battery cell or a monocrystalline silicon battery cell.

[0012] Preferably, the battery string is formed by connecting 36 or 72 groups of battery cells in series.

[0013] Preferably, the front glass plate and the battery string, the battery string and the insulating plate, and the insulating plate and the aluminum-magnesium-manganese bottom plate are all fixed by hot-melt lamination bonding with the POE film.
