Corning Incorporated GLW is benefiting from strong demand for its domestically manufactured solar products. This is driving rapid growth in its newly formed Solar segment. In the first quarter of 2026, Solar revenues surged 80% year over year to $370 million, supported by robust demand across the company’s polysilicon, wafer and module manufacturing operations. The solar business has emerged as a key contributor to Corning’s Springboard growth strategy.
It has established a vertically integrated U.S. solar manufacturing platform spanning polysilicon, ingot and wafer production, as well as solar module assembly. The company’s polysilicon business exceeded 20% corporate operating margin target in the first quarter.
The company participates in three key areas of the solar value chain: solar polysilicon, solar wafers and solar modules. It has also built the largest solar ingot and wafer manufacturing facility in the United States at its Michigan facility. Corning has already secured customer commitments for wafer production and is steadily upgrading the facility to improve throughput and long-term profitability. Moreover, the company has successfully ramped up a solar module manufacturing facility in Arizona. This is also driving growth prospects.
It previously targeted approximately $2.5 billion in annual revenues from its Solar Market-Access Platform by 2028. Backed by strong demand trends, the company indicated that it intends to raise the Solar Market-Access Platform's revenue outlook. Per a report from Mordor Intelligence, the U.S. Solar energy market is expected to witness a compound annual growth rate of 10.96% between 2026 and 2031. The entry to the Solar industry for Corning is of high return and low risk.
