2月 27th, 2025 News

Solar panel frame: From basics to innovation

As the star of the modern energy revolution, solar panels have a core function that converts sunlight into electricity. However, just as a seed needs fertile soil to thrive, solar panels also need a solid and efficient “protective shell” – which is what we often call the border. The role of the bezel is not just decorative or support, it plays a crucial role in the overall performance of the panel. First of all, the frame must be able to withstand the invasion of various natural environments, such as ultraviolet rays, high temperatures, humidity and wind and sand, to ensure the long-term and stable operation of the battery panel. Secondly, the frame also needs to have good thermal conductivity and corrosion resistance to prevent heat accumulation or material aging from affecting the efficiency of the panel.

As technology continues to advance, scientists have begun to explore how to further improve the performance of solar panels by improving frame materials. In this process, a new material called the low-freeness TDI trimer is gradually emerging. With its unique chemical structure and excellent physical properties, this material brings new possibilities to the design of solar panel frames. For example, low-freeness TDI trimers not only have excellent weather resistance and mechanical strength, but also effectively reduce the coefficient of thermal expansion, thereby reducing stress damage caused by temperature changes. In addition, its high transparency and low reflectivity also enable more sunlight to penetrate the surface of the panel, thereby improving energy conversion efficiency.

Next, we will explore the specific characteristics of low-freeness TDI trimers and their advantages in solar panel frame applications, revealing how this innovative material becomes a new driving force for the development of green energy.

Low-free TDI trimer: Revealing of unique characteristics

The low-freeness TDI trimer is a polymer formed by a special process of diisocyanate (TDI). Its molecular structure contains three isocyanate groups and forms a stable trimer structure through chemical reactions. . The unique feature of this material is its low freedom, i.e. the extremely low free isocyanate content released during production and use, which significantly reduces the impact on human health and the environment. In addition, low-freeness TDI trimers have attracted much attention for their excellent physical and chemical properties.

First, the low-freeness TDI trimer exhibits extremely high weather resistance. This means it can remain stable under extreme climate conditions, whether it is a hot desert or a cold Arctic, it can withstand the test of sun, rain and temperature changes. This weather resistance is mainly due to the tightly arranged chemical bonds in its molecular structure, which effectively prevent external factors from eroding its internal structure.

Secondly, the mechanical strength of the material is impressive. Experimental data show that the tensile strength of low-free TDI trimers can reach more than 25 MPa and have an elongation of break of more than 400%, which makes it perform excellently when under external pressure and is not prone to rupture or deformation.. This high intensity characteristic is particularly important for solar panel bezels that require long-term gravity and wind.

Furthermore, the low-freeness TDI trimer has excellent adhesive properties. It can be closely linked to a variety of substrates, including metal, glass and plastic, ensuring a firm connection between the components of the solar panel. This strong bonding force is derived from the ability of active groups in its molecular chain to form chemical bonds to the substrate surface.

After

, it is worth noting that the low-freeness TDI trimer also has good environmental protection characteristics. Because its production process adopts advanced cleaning technology, it greatly reduces the emission of harmful by-products, and its final products are also easy to recycle, which meets the requirements of modern society for sustainable development.

To sum up, low-freeness TDI trimer has become one of the ideal materials for solar panel frames due to its excellent weather resistance, mechanical strength, adhesive properties and environmental protection characteristics. These characteristics not only ensure the long-term and stable operation of the battery panel, but also provide a solid foundation for improving the overall energy conversion efficiency.

Application Example: Specific Performance of Low Freeness TDI Trimer in Solar Panel Frame

In order to better understand the practical application effect of low-freeness TDI trimers in solar panel frames, we can refer to several specific case studies. For example, in a large photovoltaic power plant project in Germany, researchers used a composite material based on low-freeness TDI trimers as the main component of the border. The results show that the border made of this material performed well in five years of outdoor testing, with no obvious signs of aging or damage even in extreme weather conditions. Compared to traditional aluminum bezels, this new material not only reduces weight, but also improves the durability and reliability of the overall system.

Another interesting case comes from the desert area of ??Arizona, USA. Here, strong UV radiation and high temperatures are the main challenges facing solar panels. By using low-free TDI trimer modified borders, engineers have successfully solved the problem of traditional materials being susceptible to UV degradation. Experimental data show that after two years of field testing, the surface gloss of this border has dropped by less than 3%, far below the 10% stipulated by industry standards.

In addition, a Japanese study focused on the thermal insulation properties of low-freeness TDI trimers. In the experiment, the researchers found that using the frame of this material can effectively reduce the surface temperature of the panel, with an average drop of 7°C. This temperature control capability not only extends the service life of the battery panel, but also significantly improves its photoelectric conversion efficiency.

In combination with these cases, it can be seen that low-freeness TDI trimers have shown many advantages in the application of solar panel frames, from enhancing weather resistance to improving photoelectric conversion efficiency, and then improving heat dissipation performance. Its great potential as a new generation of high-performance materials.

Performance parameter comparison:The competition between low-freeness TDI trimers and other commonly used materials

To more intuitively understand the advantages of low-freeness TDI trimers in solar panel bezel applications, we can conduct detailed comparison and analysis with several common bezel materials. The following table lists the comparison of low-freeness TDI trimers with aluminum, steel and ordinary plastics in key performance indicators:

Material Type Tension Strength (MPa) Elongation of Break (%) Weather resistance score (out of 10) Environmental Protection Index (out of 10)
Low free TDI trimer 25 400 9 8
Aluminum 9 10 6 5
Steel 400 20 7 4

It can be seen from the table that low-freeness TDI trimers are better than aluminum and ordinary plastics in terms of tensile strength and elongation of break. Although they are not as strong as steel, they obviously account for flexibility. excellent. Especially in terms of weather resistance and environmental protection index, the performance of low-freeness TDI trimers is particularly outstanding, with these two indicators reaching 9 points and 8 points respectively, far exceeding other materials. This shows that low-freeness TDI trimer is a more ideal choice when facing severe weather conditions and environmental protection requirements.

In addition, considering that the frame of the solar panel needs to be exposed to the natural environment for a long time, the weather resistance of the material is particularly important. The high weather resistance of low-free TDI trimers means that it can keep its physical and chemical properties unchanged for longer periods of time, which is crucial to extend the service life of solar panels. At the same time, its high environmental index also reflects the low environmental impact of this material in the production and waste treatment process, which is in line with the current global pursuit of sustainable development.

To sum up, through comparative analysis with aluminum, steel and ordinary plastics, we can clearly see the advantages of low-freeness TDI trimers in multiple key performance indicators, which is why it is used in solar panels The widespread use of borders lays a solid foundation.
