Description

Strenghthened type lightweight solar cell panel frame

Technical Field

The utility model relates to a photovoltaic module installation frame, more specifically say, relate to a strenghthened type lightweight solar panel frame.

Background

Solar energy has received very high attention as a clean green renewable energy source, and a large amount of manpower and financial resources are also invested in the nation for research and promotion. At present, a single common solar cell can only generate about 0.5V, and the open voltage of the PERC cell and the HIT cell is only about 0.7V, and the voltage is far lower than the voltage required by practical application. In order to meet the application requirements, several solar cells are connected in series to form a module, which is generally called a photovoltaic module or a solar cell module.

The photovoltaic module mainly comprises a frame, a solar cell panel, a junction box, sealant and the like. The frame is also commonly called as a solar photovoltaic cell packaging frame and is used for fixing and sealing a solar cell module, enhancing the strength of the module, prolonging the service life of the module and facilitating transportation and installation. The photovoltaic module frame is generally assembled by an aluminum alloy section and a connecting piece, the aluminum alloy section is provided with a cavity structure, two ends of the connecting piece are inserted into the cavity of the section and are fixedly connected with the section to form a frame structure, and sometimes, an accessory transverse or cross supporting piece stretching between peripheral frames is arranged to improve the supporting strength. The photovoltaic module frame made of the aluminum alloy section bar has the advantages of being strong in oxidation resistance, high in strength, good in tensile property, high in fatigue resistance value, long in service life and the like. The photovoltaic module frame needs to bear loads such as wind, snow, self weight of the solar cell panel and the like in actual work, and all acting forces can cause the frame to deflect and twist. The photovoltaic module frame is theoretically structurally strong enough to support the solar panels to protect the solar panels in the frame from damage. Due to the increase of the cost of the frame raw materials, related enterprises are also seeking for a technical scheme of designing the frame in a light weight manner, so that the frame is as light as possible under the condition of ensuring the strength of the frame. However, due to the strength of the photovoltaic module frame material and the required load bearing capacity, the wall thickness of the frame profile cannot be further reduced, otherwise the frame cannot bear the bending stress. The conventional frame reinforcing method, such as the aforementioned method of adding transverse or cross-supporting members across the inside of the frame, is a light-weight reinforcing frame for photovoltaic modules as disclosed in patent CN201821084154.3, but this method cannot effectively prevent the frame from bending or twisting.

For this reason, a new frame lightweight design concept is needed to meet the strength requirement and the weight reduction requirement of the photovoltaic module frame.
