Referring to fig. 2 and 3, the front plate 21 has a substantially inverted U-shaped cross section, and the battery layer 22 is mounted at the first front plate 211 so as to protect and limit the battery layer 22. The two second front plate portions 212 are connected to both sides of the first front plate portion 211 in the width direction, respectively.

The edge of the front plate 21 may be substantially isosceles trapezoid in shape. Therefore, the structural strength of the front plate 21 can be effectively increased, and the safety performance of the photovoltaic module 2 is improved.
