Solar Material

Inteltronic EVA (ethylene vinyl acetate) film, among all available encapsulation materials, is proven to be the most cost effective, friendly handling, and the most popular adhesive film for encapsulation of photovoltaic solar panels.

The rapid growth in the solar modules has resulted in increase the demand for EVA film worldwide. Inteltronic's EVA film's outstanding performances makes surpass 20 years of photovoltaic panel life time possible.

Photovoltaic solar panel

Photovoltaic solar panel composites of several layers including ultra clear glass, EVA film, solar cell, EVA film and TPT substrate.

EVA film

EVA is a thermoplastic copolymer resin. EVA resin, together with special additives for cross linking, is heated and mixed thoroughly and is then extruded through a flat die of a special design plastic extruding machine. EVA film is then formed. It is finally wind up in roll for storage and packing.



EVA film is used to fasten the silicon cell which converts the sun's ray's to electricity to the glass surface through heat induced molecular binding.

EVA film becomes transparent and color less upon heating.

EVA film is waterproofed in nature and against ultraviolet rays.

EVA film is an ideal outdoor adhesive film for solar modules.


High Compatibility

EVA film is highly compatible with all materials of photovoltaic solar panel such as glass, solar cell and TPT, etc.

Excellent Adhesion

All composition materials, glass, solar cell and TPT, etc. are firmly encapsulated and bonded into one full body. This characteristic protects solar cells and hold them in place and thus, guarantee photovoltaic solar panel long lasting.

Super Transparency

A piece of EVA film is encapsulated on top of solar cell. Light absorbed by solar cell passes through the EVA film. Transparency is one of the major concerns when encapsulated material is selected. “Solar” type EVA film is highly transparent. It maximizes light transmittance and thus, allowing highest power generation per square meter of photovoltaic panel.

Low Haze

Haze is another standard similar, but different, to light transmission. “Solar” type EVA has lowest possible haze. It is crystal clear with the best transmission property.

Degradation Proof

EVA is originally thermoplastic. After melted and cure, it is transformed to a thermoset material which is resistant to degradation.


Photovoltaic solar panels are usually put in open areas without, of course, any cover. The panels shall overcome long term exposure of fiery sunlight, vigorous sand storm and heavy rainfall, etc. It has to resist also sudden temperature change when, for example, a violence of shower in the evening after a long day of sunshine. Thanks to the flexibility of EVA, the encapsulation performance is good enough to resist all kinds of climatic scenarios. It resists at the beginning and it keeps on until the panel is broken.

Resists Color Fade

Yellowish of EVA would reduce light transmission. “Solar” type EVA is absolutely color fading proof. This characteristic also prevents the film from deterioration.
