Ohio Ramps Up Solar Glass Capacity for Supplying American-Made Products to First Solar

Nippon Sheet Glass Co. (NSG Group), a leading supplier of glass and glazing systems, has recently announced a significant investment to enhance its transparent conductive oxide (TCO) glass production capacity. This expansion is taking place at its Rossford, Ohio plant, specifically to cater to the growing demands of the solar market. The float line at Pilkington North America, a key member of the NSG Group, is set to commence the shipment of TCO glass for solar panels by the first quarter of 2025.

This strategic move by Pilkington will directly support the expanding manufacturing campus of First Solar, located nearby in Perrysburg, Ohio. The relationship between the two companies is well-established, with a history of collaborative manufacturing efforts. NSG Group initiated a dedicated float line for solar glass in Vietnam in January 2020 and further expanded its capacity with a new plant in Luckey, Ohio, in November 2020. Additionally, another NSG Group float line was recently completed in Malaysia. Notably, all the glass produced in these plants is exclusively supplied to First Solar. With the upcoming expansion in Rossford, NSG Group will bolster its commitment to First Solar, operating a total of five dedicated lines for the company.

First Solar, a prominent thin-film solar panel manufacturer, currently runs three manufacturing sites in Ohio, boasting an impressive annual capacity of approximately 7 GW. In addition to its Ohio operations, First Solar is expanding its footprint with the construction of two new plants outside the state: a 3.5-GW factory in Alabama and another 3.5-GW facility in Louisiana, slated to open in 2025 and 2026, respectively.

The significance of this expansion is further underscored by the requirements for “domestic content” tax credits under the Inflation Reduction Act (IRA). To qualify, solar panels must incorporate American-made components, including solar cells, frames, back rails, glass, encapsulants, back sheets, junction boxes, edge seals, pottants, adhesives, bus ribbons, and bypass diodes. First Solar is well-positioned in this regard, likely boasting the most American-centric supply chain in the industry. The expanded relationship with NSG Group ensures the continued use of American glass in its products, aligning with the IRA's domestic production criteria.

In summary, NSG Group's investment in expanding its TCO glass production capacity in Ohio is a strategic move that not only strengthens its partnership with First Solar but also contributes significantly to the American solar industry. This expansion aligns with the growing demand for domestically produced solar components, ensuring that First Solar continues to lead with an American-focused supply chain, crucial for meeting the domestic content requirements for tax credits and fostering the growth of the U.S. solar industry.
