Detailed ways

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same numbers will be used throughout the drawings to refer to the same or like parts. In addition, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the description of the present invention may be selected by the applicant according to his or her judgment, and the detailed meanings thereof are set forth herein described in the relevant section of the description. Furthermore, it is required that the present invention be understood not only by the actual terms used, but also by the meaning implied by each term.

FIG. 1 shows a cross-sectional view of a prior art solar cell mounting frame 100 . Wherein, the solar cell installation frame 100 includes: a solar cell installation notch 101 for installing a solar cell component (such as a solar cell). A side wall 102 of the frame is provided below the solar cell installation notch 101 . The side wall 102 is substantially perpendicular to the solar cell installation notch 101 . The term "approximately perpendicular" here and below means that the angle between the two parts can not only be completely perpendicular (that is, the angle is 90 degrees) in the theoretical sense, but also can be a certain deviation from the perfect perpendicular Angle, such as 89 degrees, 91 degrees, this certain offset is almost the same as the completely vertical situation in terms of technical effects, but it is more convenient for production practice, because there will be a certain production redundancy error in actual production . At the same time, the solar cell installation frame 100 also includes a support edge 103, a part of the support edge 103 is coupled to the side wall 102, and starts from the side wall 102 in the same direction as the solar cell installation notch 101 (in this embodiment, it is the attachment Extend to the right in Figure 1). During the actual installation process, the supporting edge 103 is installed on the mounting bracket (not shown) of the solar battery system below it.
