Top 10 Companies in Encapsulant Materials for PV Modules Market (2026): Market Leaders Powering Global Solar Innovation

MARKET INSIGHTS

Global encapsulant materials for PV modules market size was valued at USD 6,386 million in 2025 to USD 7,313 million by 2034, exhibiting a CAGR of 2.0% during the forecast period.

Encapsulant materials are critical components in photovoltaic (PV) modules, providing adhesion between solar cells and protective layers while ensuring durability against environmental stressors. These materials must exhibit thermal stability, UV resistance, and optical transparency. Ethylene‑vinyl acetate (EVA) dominates the market due to its cost‑effectiveness and proven performance, accounting for over 80% of applications. However, polyolefin elastomers (POE) are gaining traction as alternatives, particularly in bifacial modules, due to superior moisture resistance and longer lifespan.

Market growth is primarily driven by increasing solar energy adoption, with the Asia‑Pacific region holding a 94% market share due to large‑scale PV manufacturing in China. While EVA remains the industry standard, material innovation focuses on enhancing performance under extreme weather conditions and reducing degradation rates. Leading players like First, HIUV, and Sveck are investing in R&D to develop next‑generation encapsulants that balance cost, efficiency, and sustainability.
