Description

Technical Field

[0001] This utility model belongs to the technical field related to the photovoltaic industry, specifically relating to a steel frame assembly structure for photovoltaic modules. Background Technology

[0002] With the rapid development of the photovoltaic market, module prices are very sensitive, making cost reduction of modules particularly important, and module frames are one of the targets for cost reduction;

[0003] Steel frames (Q235 or magnesium-aluminum-zinc coated sheets) are one way to reduce costs. Steel frames are stronger than aluminum alloys, and their weather resistance can pass relevant material tests. The strength of the components can also surpass that of aluminum alloy frames under the same wall thickness and height. Furthermore, issues such as process and packaging have been resolved, and their market application has been proven.

[0004] However, steel frames also have drawbacks. They can spontaneously shatter during transport or after component installation, which greatly affects their application in components. The reasons for this spontaneous shattering are: steel frames are formed by cold bending, resulting in poor cross-sectional consistency (there may be bending stress points along the entire frame), and the warping of the entire frame is not as good as that of aluminum frames; if there are forming stress points on the frame that are in contact with the front and back during the framing process, the glass will be in a state of stress release after assembly, making it prone to spontaneous shattering.

[0005] This utility model addresses the above-mentioned problems by providing an improvement on a photovoltaic module steel frame assembly structure. Utility Model Content
