Frame structure and solar module with frame structure

Abstract

The invention discloses a frame structure and a solar module with the frame structure. The frame structure includes a first transverse plate, a second transverse plate, a first longitudinal plate, a third transverse plate, a second longitudinal plate The board body and at least one supporting element. The second transverse board is separated from the first transverse board by a first interval. The first longitudinal plate connects the first transverse plate and the second transverse plate. The third transverse board is separated from the second transverse board by a second distance. The second longitudinal plate connects the second transverse plate and the third transverse plate. The second transverse plate and the third transverse plate at least partially protrude from the second longitudinal plate, so that an open accommodating space is defined between the second transverse plate, the second longitudinal plate and the third transverse plate . The support element is detachably positioned in the accommodating space. The top surface of the support element abuts against the second transverse plate, and the bottom surface of the support element abuts against the third transverse plate.

Description

technical field [0001] The invention relates to a frame structure and a solar module with the frame structure. Background technique [0002] Generally speaking, the side of the solar panel is protected by an aluminum frame to improve the strength of the overall solar module. Mechanical load test (mechanical load test) is an important test item for solar modules. Taking the area of ​​a solar module with 60 solar panels (cells) as an example, the solar module needs to be able to load a force of 400 kg to pass the load test of 2400 Pa, and the solar module needs to be able to load a force of 900 kg to pass the load test of 5400 Pa. [0003] Designers can increase the strength of the overall solar module by strengthening the strength of the glass and aluminum frame on the solar panel. However, although the strength can be improved by increasing the thickness of the glass, the weight of the glass accounts for about 65% of the solar module, which will greatly increase the weight...

AI Technical Summary

Problems solved by technology

But in fact, the thicker the aluminum frame is, the weight and material cost will increase accordingly, and the aluminum frame is limited by the aluminum extrusion process, the aluminum frame cannot form a support column in the vertical length direction, and can only form Same support column, not cost effective

[0004] In addition, the strength of the finished aluminum frame is fixed. For example, the solar module that needs to pass the load test of 2400Pa can only use the aluminum frame designed under this load condition.

If this aluminum frame is assembled to a solar module that needs to pass the 5400Pa load test, it will fail the load test

In other words, the same aluminum frame cannot be used universally for solar modules under different test conditions, and it is relatively inelastic when used
