In the solar industry, the most common encapsulation is with cross-linkable ethylene vinyl acetate (EVA). With the help of alamination machine, the cells are laminated between films of EVA in a vacuum, which is under compression. This procedure is conducted under temperatures of up to 150°C. One. .
Once the EVA sheets have been laminated, the ethylene vinyl acetate sheets play an important role in preventing humidity and dirt penetrating the solar panels. Also with the help of the EVA, the solar cells 'are floating' between the glass and backsheet,.
[pdf] A trimming machine is used to trim, or cut, the excess material from the cell edge of the solar module while maintaining uniformity. This is the next step after a solar module has been laminated.
