[0002] The world energy crisis and environmental pollution have made it necessary for mankind to develop and utilize renewable energy and various green energy sources to achieve sustainable development. Solar photovoltaic power generation technology and industry have been fully developed. Solar photovoltaic power generation is not only an important supplement to today's energy, but also has the potential to become one of the main energy sources in the future. In addition, solar panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through photoelectric effect or photochemical effect. Compared with ordinary batteries and rechargeable batteries, solar cells are more energy-saving and environmentally friendly green products.

[0003] At present, most solar cold chain vehicles have photovoltaic modules installed on the outer wall of the cold compartment. The photovoltaic modules are usually encapsulated with aluminum alloy and photovoltaic glass, and the thickness is between 20mm and 30mm, which will significantly increase the weight of the compartment. In addition, due to the large thickness, photovoltaic modules cannot be installed on the side of the compartment, which greatly reduces the utilization rate of the surrounding energy in the compartment.

[0006] Preferably, a connection hole is provided at the edge of the resin composite plate, a square groove having the same size as the thin-film photovoltaic panel is provided on one side surface of the resin composite plate, and a quick plug hole is provided in the square groove.

[0007] Preferably, the thin-film photovoltaic panel is arranged in the square groove, and a quick plug connected to the quick socket is integrated on the thin-film photovoltaic panel, and the quick socket is also connected to a photovoltaic panel lead.

[0008] Preferably, a connecting ear plate is provided at the edge of the car body cross beam, and the connecting ear plate is riveted to the connecting hole. A bus pipe is provided inside the car body cross beam, and the photovoltaic panel lead passes through the bus pipe and is connected to the equipment end. The remaining space inside the car body cross beam except the bus pipe is filled with foam insulation material.

[0009] Preferably, internal corner pieces are bonded between adjacent inner protective plates, and an adhesive made of epoxy resin material is used for bonding, so that the seams are completely sealed.

[0010] Preferably, the foamed insulation layer is foamed polyurethane.

[0011] Therefore, the present invention adopts a cold surface integrated structure in which the above-mentioned composite material and a thin-film photovoltaic module are integrally formed, and adopts a method of integrating the thin-film photovoltaic panel with the surface of the car body. Not only will the weight of the car body not increase too much, but the resin composite material is also used for pre-embedded packaging, and its thickness is almost not increased compared to when the photovoltaic module is not installed, so that the photovoltaic module can also be installed on the side of the car body, which greatly improves the utilization rate of the surrounding energy of the car body.
