Solar Encapsulant Sheet Global Market Insights 2025, Analysis and Forecast to 2030, by Manufacturers, Regions, Technology, Product Type

Solar Encapsulant Sheet Market Summary

Introduction
Solar Encapsulant Sheets are critical materials used to protect and enhance the durability of photovoltaic (PV) modules by encasing solar cells, ensuring resistance to environmental factors like moisture, UV radiation, and temperature fluctuations. These sheets, typically made from materials like ethylene vinyl acetate (EVA), polyolefin elastomer (POE), or polyvinyl butyral (PVB), provide adhesion, insulation, and long-term reliability to solar panels. The rise of double-glass (bifacial) modules, which offer higher efficiency and longevity, has boosted demand for advanced encapsulants like POE and EPE (EVA-POE-EVA co-extruded films), known for their superior water resistance and anti-PID (Potential Induced Degradation) properties. The global solar industry has seen rapid growth, with installed capacity increasing from 117 GW in 2019 to 375 GW in 2024, projected to reach 402 GW in 2025 and 540 GW by 2028. The market is estimated at USD 3.9-5.5 billion in 2025, with a CAGR of 7.5%-12.5% from 2025 to 2030, driven by renewable energy adoption and technological advancements in PV manufacturing.
