Top 10 Companies in the EVA‑Based Solar Encapsulants Market (2026): Market Leaders Powering Global Solar

MARKET INSIGHTS

Global EVA‑based solar encapsulants market size was valued at USD 3.52 billion in 2024. The market is projected to grow from USD 4.10 billion in 2025 to USD 12.70 billion by 2032, exhibiting a CAGR of 16.2% during the forecast period.

EVA (ethylene vinyl acetate) encapsulants are polymer films that bond solar cells, provide electrical insulation, and shield modules from environmental degradation. They maintain optical clarity while delivering adhesion and weatherability, typically with 28‑33% vinyl acetate content.

Market momentum is underpinned by a surge in global solar capacity—413 GW in 2023—and by breakthroughs in anti‑PID formulations and ultra‑fast curing films. A 2024 collaboration between Mitsui Chemicals and First Solar to develop next‑generation thin‑film encapsulants exemplifies the sector’s push toward higher performance.
