Solar Cell Encapsulant Global Market Insights 2025, Analysis and Forecast to 2030, by Manufacturers, Regions, Technology, Application

Solar Cell Encapsulant Market Summary

Introduction
Solar Cell Encapsulants are specialized adhesives and sealants used to enhance the performance and longevity of photovoltaic (PV) modules by bonding components like junction boxes, inverters, frames, and cells, while protecting against environmental degradation. These materials, typically silicone- or polyurethane-based, offer high adhesion, weather resistance, and thermal stability, critical for ensuring PV system reliability. The market is closely linked to global solar growth, with installed capacity rising from 117 GW in 2019 to 375 GW in 2024, projected to hit 402 GW in 2025 and 540 GW by 2028. Chengdu Guibao Science & Technology’s 2021 launch of a 20,000-ton annual capacity facility, supporting 14 GW of PV installations, underscores the industry’s expansion. The market is estimated at USD 1.5-3.0 billion in 2025, with a CAGR of 7.5%-12.5% from 2025 to 2030, driven by solar energy adoption and demand for durable PV components.
