Solar Glass: Market Size & Forecast 2026

The global solar glass market reached approximately USD 7.8 billion in 2025, held in a structurally tight balance between crystalline-silicon module dominance, a Section 301 tariff stack that now reaches roughly 35% on Chinese-origin imports entering the United States, and a concentrated supply base where the top-three producers control the majority of patterned and AR-coated capacity. Energy accounts for 35% of finished solar glass cost, making natural-gas and electricity economics the primary margin lever for producers, while China's share of global solar glass manufacturing capacity sits at approximately 75-80%. > **Analyst Take.** The Section 301 tariff stack at 35% combined on Chinese-origin solar glass is the most consequential procurement inflection most buyers have under-priced. We expect domestic US and European supply to attract a 10-15% pricing premium to FOB China spot by 202
