Is EVA a reliable encapsulant for solar panels?
EVA has been used as a solar panel encapsulant for years, offering good protection to cells due to its mechanical strength, UV resistance, and weatherability. However, there have been concerns about its reliability as an encapsulant.
What are the disadvantages of Eva solar panels?
The main concerns with using EVA as a solar PV encapsulant are: EVA is manufactured with the use of acetate monomer, which gets hydrolyzed to acetic acid over time, causing the film to yellow or discolor. This change in color reduces visible light transmittance of solar modules over time.
Who is China's top supplier of Eva films for PV modules?
Sveck, China’s top supplier of EVA films for PV modules, has revealed plans to list shares in Shenzhen. China Guangdong Nuclear Power Corp. has selected Longi and EGing to respectively supply 238 MW and 112 MW of panels for its projects, with Longi also announcing wafer price cuts.
Does EVA encapsulate solar cells?
EVA encases over 80% of photovoltaic (PV) modules on the market today. Since EVA is inexpensive and has good optical properties, it serves as a good encapsulant for solar cells.
Who makes PV Eva resin?
Formosa Polypropylene (Ningbo) sustains share of solar-grade resin supply, whilst that of Levima Advanced Materials continually increases, with 18,000 MT capacity from modified lines expecting to come online this year. New PV EVA resin manufacturers include BASF-YPC, Yulin Energy and Chemical, and Sinochem Quanzhou Petrochemical.
How much Eva resin can be produced in 2022?
Based on the current EVA resin supply of the two manufacturers and on the premise that overseas supply sustains, cumulative solar-grade EVA resin capacity may reach 1,120,000 MT by the end of 2022, sufficient to fulfil EVA resin demand of 890,000 MT to 930,000 MT.
