Description

Technical Field

[0001] The utility model relates to the technical field of solar panel assembly, in particular to a honeycomb structure solar panel device. Background Art

[0002] Solar panels are composed of several monocrystalline silicon or polycrystalline silicon solar cells assembled on a board in a certain way. Since monocrystalline silicon or polycrystalline silicon solar cells are generally encapsulated with tempered glass and waterproof resin, they are durable and have a service life of generally 15 years and up to 25 years. They have a high charging conversion efficiency and are widely used.

[0003] Since both tempered glass and solar cells have a certain weight, the bottom of the solar panel is usually supported and fixed by a material with a certain load-bearing capacity, such as aluminum alloy or steel sheet.

[0004] Under the same conditions, the deformation of aluminum alloy profiles is 2.9 times that of steel, and its load-bearing capacity is weaker than that of steel. In terms of corrosion resistance, aluminum alloy is in the passivation zone under the atmospheric environment, and a dense oxide film is formed on its surface, which prevents the surface of the active aluminum matrix from contacting the surrounding atmosphere. Therefore, it has very good corrosion resistance, and the corrosion rate decreases with time. Under normal conditions (C1-C4 environment), 80μm galvanized steel can be used for more than 20 years, but in high-humidity industrial areas or high-salinity seashores or even temperate seawater, the corrosion rate is accelerated, the galvanizing amount needs to be more than 100μm, and regular maintenance is required every year. In terms of corrosion resistance, aluminum alloy is far superior to steel.

[0005] Comprehensive analysis shows that steel supports have a slight advantage in overall load-bearing capacity, while aluminum alloy supports lead in terms of corrosion resistance, installation convenience, subsequent maintenance costs and recyclable value.

[0006] Therefore, how to select the supporting material of solar panels and optimize their structure so that they can use less material and achieve a stable support effect is a technical issue that needs to be studied. Utility Model Content

The bottom of the groove is stacked with a honeycomb aluminum core, a reinforcement plate and a solar panel in sequence from bottom to top, and the upper surface of the solar panel is flush with the upper surface of the limiting protrusion.

[0035] Specifically, photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. The key component of this technology is solar cells. After being connected in series and packaged for protection, solar cells can form a large-area solar cell module, which is then combined with power controllers and other components to form a photovoltaic power generation device.
