Encapsulation materials are critical in protecting PV cells from moisture, UV, mechanical stress, and thermal cycling. They also enhance module performance, extend warranty life, and enable new module formats such as bifacial, flexible, and BIPV systems.

The global Solar Encapsulation Market size was valued at USD 4,825.6 million in 2023 and is projected to reach USD 9,020.6 million by 2031, growing at a CAGR of 8.25% from 2024 to 2031. In the scope of work, the report includes products offered by companies such as Mitsui Chemicals, Inc., First Solar, Elkem ASA, Dow, H.B. Fuller Company, 3M, DuPont, Saint-Gobain Group, RenewSys India Pvt. Ltd., Evonik Industries AG, and Others.

Key highlights:

  • EVA is the dominant material, though non-EVA chemistries are gaining market share.
  • Rooftop solar represents the largest application segment due to residential and commercial distributed generation.
  • Asia-Pacific is the fastest-growing region and is expected to maintain high growth due to strong solar deployment and local manufacturing.

Market Growth Drivers

Global electricity demand, renewable energy targets, and rising solar installations drive the market. Encapsulant demand is directly linked to module shipments and system expansion.

Primary drivers:

  • Government incentives, subsidies, and industrial decarbonization policies.
  • Falling PV system costs and improved energy yields, encouraging new installations.
  • Increasing adoption of long-warranty modules requiring superior encapsulation.
  • Growth of bifacial, thin-film, and flexible modules needing specialized encapsulants.

Market Dynamics & Demand Drivers

Encapsulant suppliers operate at the intersection of materials science, PV manufacturing, and supply chains.

Key dynamics:

  • Material evolution: EVA remains common, but POE and other chemistries are increasingly used for better UV resistance and reduced yellowing.
  • Raw material price sensitivity: Feedstock and polymer price fluctuations affect margins, prompting procurement diversification.
  • Sustainability pressures: Emphasis on recyclable or lower-impact encapsulants and circular supply-chain practices.
  • Localization of supply chains: Countries promoting PV self-reliance stimulate local encapsulant production.
