[0002] People often install photovoltaic panels on their roofs to obtain clean energy. In related technologies, photovoltaic panels are curved panels, which include cells and a wavy mounting surface. The cells fit the wavy mounting surface and are bent along the wavy mounting surface. The cells are easily broken, which greatly reduces the service life of the photovoltaic panels. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present application proposes a photovoltaic panel.

[0007] The present application provides a photovoltaic panel including a first curved panel and a plurality of battery components.

[0008] The outer surface of the first curved plate includes a first front surface and a first back surface, and the first front surface and the first back surface are arranged at intervals along the thickness direction of the first curved plate.

[0009] A plurality of battery components are mounted on the first back surface of the first curved plate.

[0010] Specifically, the plurality of battery components are arranged flatly, that is, any two batteries in the plurality of battery components are not overlapped.

[0011] Specifically, the first back side includes a plurality of plane segments connected in sequence, and any two adjacent plane segments enclose an angle structure. That is, the first back side is a serrated surface. Each battery component is attached to a plane segment, that is, each battery component is assembled with a plane segment, and each battery component does not span different plane segments. Each battery component is laid flat and attached to a plane segment. In other words, the plane segment serves as an installation carrier for the battery component, and has the function of installing and fixing the battery component. Since the battery component does not span different plane segments, the battery component will only be arranged in accordance with the shape of the plane segment, and the battery component will not be bent. In this way, while ensuring the performance of the photovoltaic panel, the probability of battery component damage is reduced, which is beneficial to extending the service life of the photovoltaic panel and improving the performance and market competitiveness of the photovoltaic panel.

[0012] The photovoltaic panel described above in this application may also have the following additional technical features:
