Description

Technical Field

[0001] This utility model relates to the field of solar panels, and in particular to a solar panel that generates electricity through double-sided light transmission. Background Technology

[0002] Solar panels are devices that directly convert solar energy into electrical energy using the photovoltaic effect that occurs in semiconductor materials under sunlight. It is one of the most direct ways to utilize solar energy, and most panels are made of silicon. Since solar photovoltaic power generation can generate electricity wherever there is sunlight, it is suitable for a wide range of applications, from large power plants to small portable chargers.

[0003] In the process of using existing solar panels, light energy is generally absorbed and electrical energy is converted through a single-sided solar panel. However, as the angle of sunlight changes, the efficiency of solar panels in absorbing light energy gradually decreases, which greatly affects the efficiency of photoelectric conversion and the output efficiency of electrical energy, which is very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a double-sided transparent solar panel for power generation. It has an ingenious structure that achieves photoelectric conversion through double-sided light transmission and achieves concealed wiring through the cooperation of an aluminum frame and a junction box. This ensures both electrical conduction and the photoelectric conversion efficiency of the solar panel, making it convenient and efficient.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has at least two solar panel bodies, which are connected sequentially by hinges; each solar panel body includes an aluminum frame and a solar panel layer installed in the aluminum frame. The solar panel layer includes two transparent film layers and a battery cell group disposed between the two transparent film layers. The battery cell group is formed by connecting multiple arrayed double-sided battery cells in series. Each transparent film layer and battery cell group are laminated and cured to form the solar panel layer. Each aluminum frame is provided with an installation groove. The solar panel layer is fixedly installed in the aluminum frame by inserting into the installation groove. Each solar panel body is provided with a junction box containing multiple electrical components. Each junction box is installed on the solar panel layer and the aluminum frame, and each electrical component in the junction box is electrically connected to the battery cell group. The junction boxes on adjacent solar panel bodies are arranged adjacently. Adjacent junction boxes are electrically connected by flexible busbars. Each aluminum frame is provided with a through groove through which the flexible busbar can pass. The two ends of the flexible busbar pass through the corresponding through groove and extend into the junction box, and are electrically connected to the electrical components in the junction box.

[0006] Furthermore, the aforementioned aluminum frame is composed of multiple aluminum profiles connected by connecting brackets. Each aluminum profile includes an integrally formed front end plate, side plate, and rear end plate. The front end plate, side plate, and rear end plate all extend from one end of the aluminum profile to the other end. The side plate is provided with a first partition plate integrally formed with and perpendicular to the side plate. The first partition plate is disposed between the front end plate and the rear end plate and is parallel to both the front end plate and the rear end plate. The first partition plate, the front end plate, and the side plate form an installation cavity for embedding the solar panel layer. The installation cavity on each aluminum profile forms an installation groove for installing the solar panel layer.

[0007] Furthermore, each front-end plate is provided with a pressing part that can press the solar panel layer embedded in the mounting cavity. The pressing part is integrally formed with the front-end plate and extends from one end of the front-end plate to the other end of the front-end plate.

[0008] Furthermore, a second partition plate is provided between the first partition plate and the rear panel. The second partition plate is integrally formed with the partition plate and the rear panel and is arranged perpendicularly. Both the first partition plate and the second partition plate extend from one end of the aluminum profile to the other end of the aluminum profile. The second partition plate, together with the first partition plate, the side panel, and the rear panel, forms an inner cavity for strengthening the aluminum frame. The second partition plate is also provided with a reinforcing rib integrally formed with the second partition plate. The reinforcing rib is arranged in the inner cavity and extends from one end of the second partition plate to the other end of the second partition plate.

[0009] Furthermore, each connecting corner bracket is covered with a corner protector, and the front, side, and rear plates at the intersection of each aluminum profile are all covered within the corner protector.

[0010] Furthermore, each of the second partition plates, together with the front and rear plates, forms an outer cavity with an opening. Magnets are installed inside the outer cavity. After each adjacent solar panel body is rotated and folded, it is fixed by the magnetic attraction of each magnet inside the aluminum frame.

[0011] Furthermore, each solar panel body is provided with a support assembly that can support each solar panel body after it is unfolded. The support assembly includes a support base fixed to an aluminum profile and a U-shaped strut rotatably connected to the support base. Both ends of the U-shaped strut are provided with connecting rotating plates. The support base is provided with a rotating groove for the connecting rotating plates to rotate.
