3. Solar EVA Full Feature

EVA film is the most popular encapsulation  for photovoltaic solar panel. A photovoltaic solar panel is a composite of several layers including ultra clear glass, EVA film, solar cell, EVA film and TPT substrate.

After years of practicing, EVA film, among all available encapsulation materials, is proven to be the most cost effective, friendly handling, lowest operating cost with outstanding performances.

EVA stands for ethylene vinyl acetate. It 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.

Recipe of EVA film for photovoltaic encapsulation is different from those films for furnishing, decoration and building purpose. It is re-formulated such that it suits precisely all criteria for photovoltaic purpose.

“Solar” type EVA interlayer film contains no plasticizer. This extraordinary adhesive film is non-sticky and inert to water moisture at room temperature. Handling and glass assembly could be done easily. Its outstanding performances guarantee more than 20photovoltaic panel life time.

Key Specification

1) Excellent durability, such as weather resistance, high-temperature and high humidity resistance, UV light resistance.2) Excellent adhesion to glass, metal and plastics PET, TPT, Maintaining long term adhesion.3) Excellent light transmittance and transparency.4) Inactivation and harmless in solar cells during processing.5) Have a high cross linking rate after lamination.6) Good encapsulating propertie 

EVA film is the encapsulating materials for PV modules. The fast cure film is the new type with better UV light resistance and bubble free in lamin.

Product Approval UL,SGS,TUV.

Solar EVA Characteristics

1. High light transmittance and Low haze rate during long time aging process.2. Excellent bonding and adhesion to glass, cell back sheet, and cell.3. Special knurling on the surface for air exhausting, which greatly reduces the rejection rate.4. Excellent anti-yellow resistance for longer life.5. High cross linking rate to any prevent cell damage.EVA Sheet Solar Product Specifications1. Length: Measured using an automatic measuring system. The conventional 0.45mm thickness has a length of 100m. Tolerance ±1.5m.2. Width: Measured using a tape measure with a resolution of 1mm. Max width 1300mm, Common width 1000mm. Tolerance ±10mm.3. Thickness: Measured using a dial thickness gauge with a resolution of 1/1000mm. Varies between between 0.3mm to 1.0mm, Conventional thickness 0.45mm. Tolerance ±0.015mm.* The standard length, width, thickness can be modified as per requirement in case of bulk orders.Solar EVA Transportation And Storage1. Storage period cannot exceed six months. We recommend customers to use them up within three months. Storage period starts from the date on the certificate.2. Avoid heat and humidity in transportation and storage. Stack tidily in 4 layers without bending.3. Avoid direct exposure to sunlight. Keep away from the heating equipments and dust.4. It is suggested to use the film at once or keep it wrapped properly to maintain the shell life.For Best results: Maintain temperature between 0-30°C and humidity <60% in the warehouse.
