All About Ethylene Vinyl Acetate- It’s Composition And ApplicationPosted by Vishakha Renewables on October 25th, 2019 If you know about solar panels then you must have heard about EVA films which are the main component used for traditional solar panel lamination. So, what exactly are these EVA films? Basically, in the solar industry, the most common encapsulation is cross-linkable with ethylene-vinyl acetate. Then with the help of the lamination machine, the cells are laminated between films of EVA in a vacuum under compression. While this process is conducted under temperatures of up to 150oC. The only drawback of the EVA sheets is that it is not UV-resistant and therefore a protective front glass is required for the UV screening. However, if you are in need of EVA sheets for your solar panels then you can contact Vishakha Renewables which is one of the leading EVA sheet manufacturers in India. Long Term Encapsulation and Protection Once the EVA sheets are laminated, it plays an important role in preventing humidity and dirt penetrating the solar panels. Moreover, the solar cells ' floating’ between the glass and back sheet with the help of the EVA, helps to absorb the shocks and vibrations thus protecting the solar cells and its circuits.
Properties of EVA Sheets
EVA films are durable enough to withstand high temperatures and high humidity if they are made from quality products.
EVA films are excellent at adhesive bonding to solar glass under the right circumstances. Further, it also bonds very well to the back sheet of the solar panel.
EVA sheets for solar cells encapsulation also provide excellent transparency which means that the optical transmission is acceptable and doesn’t block too much of the sunshine that reaches the solar cells. Today, some manufacturers use a transparent back sheet that offers transparency between the cells. This type of module is known as semi-transparent.
