Float-glass manufacturer Stewart Engineers is opening a solar glass manufacturing facility in Ohio and expects production to begin in March 2026. The new company division Stewart Glass is working out of a 267,000-ft2 facility in Logan, Ohio, about an hour southeast of Columbus.
Stewart Glass will make two types of 3.2-mm low-iron rolled solar glass, one with anti-reflective coatings for the front and one for the backside without anti-reflective properties.
The company will first begin producing front-pane glass in March and then will equip the site with a second line in June to make back-pane glass.
Stewart Glass estimates that the Ohio site will manufacture enough front glass to supply 6,500 solar panels annually (conservatively using 400-W panels, that would equate to 2.6 GW of solar panels annually).
Stewart Engineers was founded in 1986 and holds expertise in float bath technology. Headquartered in North Carolina, the company sets up glass manufacturing facilities across the globe. The Ohio plant appears to be the company’s first solar-focused endeavor.
