EVA's widespread adoption is driven by its excellent optical transmission, strong adhesion to solar cells, and cost-effectiveness, making it the preferred choice for encapsulating crystalline silicon modules globally. The rapid expansion of solar PV installations, fueled by increasing electricity demand from population growth and accelerated urban development, continues to support segment growth. In addition, the global transition from conventional fossil fuel-based energy to solar power, particularly in economies such as China, India, the U.S., and Germany, further boosts demand for EVA-based encapsulation materials, especially in large-scale solar farms exceeding 200 MW.

The increasing module size and higher power ratings in utility-scale solar projects have underscored the importance of materials like EVA, which offer proven long-term durability and performance under varying climatic conditions. Its ease of lamination and compatibility with both front and rear surfaces of solar cells make it ideal for streamlined mass production. Furthermore, EVA sheets' lightweight nature and flexibility contribute to improved module handling and structural design, which is critical for emerging applications such as floating solar, building-integrated photovoltaics (BIPV), and desert-based installations. As the renewable energy landscape evolves, EVA is expected to retain a strong foothold, while newer alternatives like Polyolefin Elastomers (POE) and Thermoplastic Polyurethane (TPU) gain momentum in niche, high-efficiency segments requiring enhanced thermal and UV resistance.

Technology Insights

Based on technology, the crystalline silicon solar segment led the market with the largest revenue share of 83.6% in 2025. The crystalline silicon solar segment accounted for the largest revenue share of approximately 84.40% in 2024. The global rise in electricity demand due to rapid urbanization, industrial expansion, and population growth has significantly boosted the adoption of crystalline silicon solar technology, driving the use of encapsulation materials tailored for this segment. Crystalline silicon modules, including monocrystalline and multicrystalline types, are favored for their high energy efficiency, long operational life, and well-established manufacturing base. The segment’s dominance is expected to continue over the forecast period, supported by falling module costs, consistent technology improvements, and supportive policy frameworks promoting solar adoption at utility and commercial scales.

While crystalline silicon remains the backbone of the solar market, newer technologies such as thin-film and tandem cells are gradually gaining attention. However, skepticism remains among some major players regarding the scalability and durability of alternatives compared to traditional crystalline silicon. Material demand in this segment is also subject to supply chain fluctuations and pricing volatility in encapsulant components like EVA and POE. On the other hand, the thin-film segment is experiencing niche demand in applications like building-integrated photovoltaics (BIPV), flexible modules, and off-grid solutions. Nonetheless, the robust infrastructure supporting crystalline silicon module manufacturing and its proven field performance are expected to uphold its dominant share across established and emerging solar markets worldwide.
