Top 10 Companies in the Poly(Ethylene-co-Vinyl Acetate) (EVA) Encapsulant for Bifacial Photovoltaic Modules Market (2026): Market Leaders Driving Global Renewable Energy

MARKET INSIGHTS

Global Poly(Ethylene-co-Vinyl Acetate) (EVA) Encapsulant for Bifacial Photovoltaic Modules market size was valued at USD 1.84 billion in 2025. The market is projected to grow from USD 2.06 billion in 2026 to USD 5.12 billion by 2034, exhibiting a CAGR of 10.7% during the forecast period.

EVA encapsulants are polymer-based protective films widely used in photovoltaic module manufacturing to bond and seal solar cells between the front glass and backsheet or, in the case of bifacial modules, between dual glass layers. These materials provide critical functional properties including high optical transmittance, moisture resistance, thermal stability, and long-term adhesion, all of which are essential for maintaining module performance and durability over the standard 25–30 year operational lifespan of solar installations.
