It consists of a water storage tank and a heat collection tank. The heat collecting box is filled with working medium. The heat collecting box is a cuboid. There is a heat collecting plate on the front of the heat collecting box. There is an infrared heat-absorbing paint layer on the surface of the heat collecting plate. There is a vacuum transparent cover in front of the heat collecting plate. The outside of the heat collecting box is provided with a heat collecting box insulation layer. The heat collecting box can be embedded in the sunny wall of the building residents, and can also be hung on the sunny wall. The water storage tank is placed indoors; Chinese Patent Application No. CN200720102718.7 discloses an external wall-mounted solar water heater, which solves the problem that the floor-mounted installation of solar water heaters in the prior art limits the widespread use of solar energy. The external wall hanging type solar water heater includes a water heater body and a water storage tank, and is characterized in that the water heater body is installed on a bracket, and the bracket is composed of a horizontal bracket bottom plate and a vertical bracket side plate. This utility model is not installed on the roof of the building, it will not have any impact on the waterproof layer, and there will be no disputes about occupying the public use layer; users on any floor can install it, and solar water heaters are no longer exclusive to high-rise buildings; the water storage tank can be moved indoors , easy to adjust the water temperature; beautiful, light.

As can be seen from the above, the existing wall solar energy utilization is also limited to curtain walls or water heaters are installed on the wall, and it is not possible to integrate the wall in a large area to utilize solar energy.

Utility model content

The purpose of the utility model is to overcome the defects of the above background technology, and provide a photovoltaic building integrated solar wall panel.

The technical scheme of the utility model is as follows:

A photovoltaic building integrated solar wall panel, including a base plate and a solar panel, the solar panel is distributed on the front of the base plate, wherein the solar panel includes a transparent TPT layer and a solar sheet from top to bottom, the The solar panel and the substrate are connected by EVA bonding or encapsulation or lamination or potting and curing, and the back of the substrate board is provided with at least two hanging grooves that allow the substrate and the wall to be hung and combined through locks And at least one wiring slot arranged between the hanging slots.

The aforementioned substrate board is made of materials such as ceramic board, aluminum-plastic board, stone board, cement board, fiber board or plastic board.

The cross-section of the aforementioned hanging groove is T-shaped with a wide inside and a narrow outside.

At the junction slot on the back of the substrate, there are at least two small holes for passing the solar cell welding wires on the front.

A junction box is welded in the aforementioned junction slot.

The solar cells are crystalline silicon cells or amorphous silicon cells or copper indium gallium selenide cells or nanometer cells or thin film cells.

As can be seen from the above description, compared with the background technology, the existing solar photovoltaic modules generally consist of an upper layer of high light-transmitting glass, a lower layer of TPT board, and an EVA film and solar cells in the middle. Common photovoltaic modules are produced through a lamination process. as a lighting surface. The utility model adopts transparent TPT as the lighting surface, and base materials such as wallboards as the back material, which not only retains the excellent performance of ceramic boards, cement fiber boards, stone boards, aluminum-plastic boards or other building materials as wall building enclosure materials, The high light transmission and high weather resistance performance of transparent TPT material is also used. Second, in the present invention, the battery assembly and the wall panel achieve a truly integrated structure. The solar cell structure and the substrate are integrated through the lamination or glue curing process of the substrate and the battery sheet, EVA, transparent TPT and other materials, which is completely different from the traditional structure where ordinary components are installed on the wall through support. The installation method, degree of difficulty, and architectural beauty all achieve better results. Third, the present invention carries out special electrical connection design to the structure of wall panel. Holes are made on the back of the substrate, and the junction box of the component is hidden in the junction slot on the back. The hanging groove of the substrate is combined with the support structure embedded in the wall through the lock. This structure makes the construction and electrical connection of the wall panel easy. made easy and convenient. Fourth, the solar cells in the solar wall panels of the present invention can be crystalline silicon, or other amorphous silicon thin-film cells or other chemical substance cells.
