[0034] For example, the two sides of the corner guard main body 1 are L-shaped, the included angle α of the two sides of the corner guard main body 1 should be equal to the included angle β of the horizontal frame and the vertical frame of the photovoltaic module frame, or | α- β | ≤ γ, wherein γ is the maximum angle error value allowed for the smooth assembly of the corner guard main body 1, which can be determined according to actual production size, material and the like of the corner guard main body 1, according to actual test or simulation experiment, which will not be repeated here.

[0035] It should be noted that the cross-sectional shape and size of the corner guard main body 1 are only related to the cross-sectional shape and size of the photovoltaic module frame, and are not affected by the length and width of the photovoltaic module frame.

[0036] The length of the two sides of the corner guard main body 1 is determined according to the length of the sharp blade section in the actual assembly process, under the premise that the cross-sectional shape and size of the photovoltaic module frame are consistent, in order to reduce the model of the corner guard main body 1, the side length l of the corner guard main body 1 can be greater than the maximum sharp blade section length L.

[0037] In order to facilitate the clamping assembly of the corner guard main body 1 and the photovoltaic module frame, the corner guard main body 1 should have a certain elasticity to ensure the deformation ability of the corner guard main body 1 and facilitate the corner guard main body 1 to be sleeved outside the corner of the photovoltaic module frame.
