米国の太陽電池用封止材の市場規模、シェア、動向分析レポート：材料別、技術別、用途別、セグメント別予測、2025～2033年

米国の太陽電池用封止材市場サマリー

米国の太陽電池用封止材市場規模は2024年に約10億5,000万米ドルと推計され、2033年には21億8,000万米ドルに達すると予測され、2025年から2033年までのCAGRは7.9%で成長します。この市場を牽引しているのは、強力な連邦政府のインセンティブ、州レベルの再生可能エネルギーポートフォリオ基準（RPS）、積極的な太陽光発電導入目標に支えられた太陽光発電部門の急拡大です。

太陽電池用封止材は、湿度、紫外線暴露、熱サイクルによる劣化から太陽電池を保護する上で極めて重要であり、特に米国の多様な気候に関連しています。送電網の脱炭素化と太陽光発電の自給自足の推進は、インフレ削減法（IRA）に基づく現地製造の取り組みと相まって、耐久性があり高性能の封止材に対する国内需要を高め続けています。

手ごろな価格と良好な機械的・光学的特性から、米国では依然としてエチレン酢酸ビニル（EVA）が最も広く使用されているが、特にユーティリティスケールや二面式PV用途では、耐候性が向上し耐用年数が長くなるポリオレフィンや熱可塑性封止材などの先端材料が徐々に採用されつつあります。First Solar、DuPont、3M、RenewSysなどの主要企業は、住宅用および公共施設用太陽光発電市場の需要拡大に対応するため、研究開発に投資し、米国での生産を拡大しています。米国がクリーンエネルギーへの移行を進めるなか、ソーラー用封止材市場は国の広範な気候・エネルギー目標に沿って着実に成長する態勢を整えています。

U.S. Solar Encapsulation Market Summary

The U.S. solar encapsulation market size was estimated at approximately USD 1.05 billion in 2024 and is projected to reach USD 2.18 billion by 2033, growing at a CAGR of 7.9% from 2025 to 2033. The market is driven by a rapidly expanding solar PV sector, supported by robust federal incentives, state-level renewable portfolio standards (RPS), and aggressive solar deployment targets.

Solar encapsulation is critical in protecting solar cells from degradation due to humidity, UV exposure, and thermal cycling challenges, particularly relevant in diverse U.S. climates. The push for grid decarbonization and solar self-sufficiency, coupled with local manufacturing initiatives under the Inflation Reduction Act (IRA), continues to elevate domestic demand for durable and high-performance encapsulants.

Due to its affordability and favorable mechanical and optical characteristics, ethylene vinyl acetate (EVA) remains the most widely used encapsulant material in the U.S. However, the market is gradually adopting advanced materials such as polyolefins and thermoplastic encapsulants that offer enhanced weather resistance and longer service life, particularly in utility-scale and bifacial PV applications. Key players, including First Solar, DuPont, 3M, and RenewSys, are investing in R&D and expanding U.S.-based production to meet growing demand from residential and utility-scale solar markets. As the U.S. transitions toward clean energy, the solar encapsulation market is poised for steady growth, aligned with the nation's broader climate and energy goals.
