Application of EVA Film
Long term encapsulation and protection
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, helping to soften shocks and vibrations and therefore protecting the solar cells and its circuits.

EVA and TPT layer[/caption]
Asetad finyl ethylen (EVA) eiddo
Gwydnwch
Quality EVA film is known for its excellent durability, also in difficult weather circumstances, such as high temperature and high humidity.
Bondio
Under the right circumstances, EVA film will have excellent adhesive bonding to solar glass (NOT standard glass, solar glass has a rough surface). Also EVA bonds very well to the backsheet.
Optegol
EVA is known for its excellent transparency. This means that the optical transmission is acceptable and doesn't block too much of the sunshine trying to reach the solar cells. Nowadays, several manufacturers in Asia use a transparent backing, which has transparency between the cells as a result. This type of module is known as lled dryloyw.
