Stewart Glass has announced plans to begin production on its second solar glass line in June 2027, marking a significant expansion of its U.S.-based manufacturing capacity for photovoltaic materials.

According to the company, all planning and engineering work for Line 2 has already been completed, enabling a streamlined transition from development into operational readiness. This positions Stewart Glass to accelerate its scaling strategy in response to rising demand within the North American solar energy sector.

The new production line will focus on high-volume manufacturing of crystalline solar front and back glass, designed specifically for photovoltaic applications. The facility is engineered to deliver consistent quality and performance standards required by utility-scale and commercial solar projects.

Line 2 is expected to have a production capacity of 250 tons per day. It will produce ultra-clear crystalline solar glass in thicknesses ranging from 2.0 mm to 3.2 mm. The product specification includes dual-layer anti-reflective coating technology and full tempering, ensuring enhanced durability, optical performance, and long-term field reliability.

The expansion reflects Stewart Glass’s broader objective of strengthening domestic solar supply chains and reducing reliance on imported photovoltaic components. By increasing local production capacity, the company aims to support ongoing investment in renewable energy infrastructure across the United States.
