EVA (Ethylene Vinyl Acetate) encapsulating film sheet 100X100 cm
Some products called encapsulants are not designed for the encapsulation of photovoltaic cells as they contain fillers and are not weatherproof.
The encapsulation of solar cells requires materials with stable thermal conductivity and UV filter; for a solar panel that lasts over time, we therefore recommend using only QSIL or EVA.
EVA (Ethylene Vinyl Acetate) Encapsulating Film Sheet 100X100 cm
Description
Source Wikipedia: Ethylene vinyl acetate (often abbreviated as EVA) is a copolymer plastic made from ethylene and vinyl acetate.
In the production of photovoltaic solar panels, EVA sheets are used to seal everything. The cells, assembled in strings and connected in series, are enclosed between two EVA sheets to form a kind of sandwich; then the photovoltaic solar panel, still divided into many layers: Glass + EVA + cells + EVA + Back sheet, is subjected to a vacuum thermal process, called lamination, which by bringing the EVA to temperatures above 150 °C for about 10 minutes, allows the EVA to polymerize and encapsulates and isolates everything from the air, thus ensuring a very long lifespan.
EVA is specially formulated for encapsulating solar cells and will not change its structure when exposed to the sun, heat, or cold, is optically transparent, and easily applicable.
EVA Film is a solid form of encapsulant and is manipulated and installed with heat using a laminator or at home with heat guns.
The advantages of EVA film are:
- High tensile strength
- Excellent transparency
- Exceptional adhesion
 | Heating the EVA film produces toxic fumes, always use a mask to protect the mouth, nose, and eyes during encapsulation with a heat gun. |
