Solar energy is both primary energy and renewable energy. It is rich in resources and can be used free of charge without transportation and without any pollution to the environment. Create a new form of life for mankind, so that society and humanity enter an era of energy conservation and pollution reduction. A photovoltaic panel assembly is a power generating device that produces direct current when exposed to sunlight. Solar energy utilizes a solid photovoltaic cell made up of almost entirely semiconductor materials. Since there is no active part, it can be operated for a long time without causing any loss. The photovoltaic panel assembly can be made in different shapes, and the components can be connected to generate more electrical energy. In the prior art, the solar panels are mostly monolithic or monolithic, which is inconvenient to carry. There is also the use of plastics with low hardness to fix the solar cells, or directly fix the solar cells to the flexible material, which easily causes damage to the solar cells.

Utility model content

The utility model provides a foldable solar panel according to the disadvantages of being difficult to carry and easy to damage in the prior art.

The utility model solves the problem that the solar energy is inconvenient to carry. The design scheme is to lay the solar panel on the aluminum alloy bottom plate, and then fix the bottom plate on the substrate of the soft material, and leave a gap for folding when laying. The purpose of folding and carrying the solar panel is achieved, and the aluminum alloy is light in weight and high in hardness, and can protect the solar cell while being easy to carry.

In order to solve the above technical problems, the present invention is solved by the following technical solutions:

A foldable solar panel comprises a solar panel, a substrate, a socket and a solar controller; the solar panel comprises a solar cell and an aluminum alloy bottom plate, the solar cell is sequentially laid on the aluminum alloy bottom plate, the solar cell and the aluminum alloy bottom plate Fixed connection; the bottom of the aluminum alloy bottom plate is provided with a riveting hole, the aluminum alloy bottom plate is riveted to the substrate through the riveting hole, and a gap for folding is left between the aluminum alloy bottom plates; the solar battery is connected to the socket through the wire; the solar controller has a socket A matching socket; the side where the substrate is connected to the solar panel is the front side of the substrate. The aluminum alloy bottom plate functions to fix and protect the solar cell. Considering the hardness of the aluminum alloy is large, the aluminum alloy bottom plate cannot be fixed to the substrate by common sewing means, so the hole is punched in the aluminum alloy bottom plate, and then riveted. The way to connect the two. A gap is left between the aluminum alloy bottom plates, and the substrate itself is a flexible material such as cloth. The utility model can be folded at the gap to achieve the purpose of folding and carrying the solar panel.

Preferably, a through hole is formed in the gap between the aluminum alloy bottom plates, and the socket and the connected wires pass through the through hole and are drawn from the reverse side of the substrate. For aesthetic reasons and ease of use, the substrate has through holes that allow the socket to pass from the hole to the opposite side of the substrate for easy connection to the battery or load.

Preferably, a loop is also included, the loop being fixedly coupled to the front edge of the substrate. The hanging loop is used for hanging the utility model in some occasions, and the utility model has the advantages of convenient use and wide application range.

Preferably, the back side of the substrate is provided with pockets that are sized to match the size of the solar controller. The pocket is used to place the solar controller to avoid missing and missing when carrying.

Preferably, the front edge of the substrate is provided with a Velcro. Velcro is used to make the front side fit each other when the device is folded and carried, to avoid ash and damage, and to make the carrying process more convenient.

Preferably, the substrate material is one of flexible fiber materials. In view of the fact that the present invention is to achieve a foldable effect, the substrate must be made of a relatively soft material, and a suitable material is a nonwoven fabric.

The utility model adopts the above technical solutions and has remarkable technical effects: the solar cell panel can be folded and carried, the use process is convenient and simple, the application occasion is wide, the portability is convenient, and the pressure resistance is sufficient.
