Japanese solar manufacturer Toyo has officially expanded its solar module manufacturing facility in Humble, Texas, marking a key operational upgrade that lifts the plant’s total nameplate capacity to 2GW, the company confirmed at a recent ribbon-cutting ceremony.
The expansion follows the firm’s strategic capacity upgrade plan unveiled in June 2026, which includes adding 1.5GW of heterojunction (HJT) cell manufacturing capacity at the Texas site. Toyo has updated its construction timeline, confirming the HJT cell facility is scheduled to finish construction in the first quarter of 2028. To fund the HJT production expansion, the company secured financing through selling over 4.5 million shares worth a total of $4.5 million throughout the summer, backed by steady revenue growth from the second half of 2024 through the end of 2025.
Addressing attendees at the ribbon-cutting event, Toyo Chairman and CEO Takahiko Onozuka hailed the 2GW module expansion as a pivotal milestone for the company’s U.S. manufacturing layout. He emphasized that the upcoming HJT cell manufacturing deployment represents Toyo’s next core development step to strengthen its local production capabilities.
U.S. government officials recognized the project’s value for domestic manufacturing revitalization. Jeffrey Kessler, Under Secretary of Commerce for Industry and Security, attended the ceremony and stated that the expanded solar plant aligns with the current administration’s initiatives to boost domestic manufacturing construction. He credited the project’s advancement to the Trump administration’s policies aimed at reshoring manufacturing industries and creating local jobs.
Christian Menefee, Democratic U.S. Representative for Texas’ 18th congressional district, echoed bipartisan support for onshoring efforts. He noted that despite partisan differences in Washington, there is broad consensus on the critical importance of bringing production and employment back to the U.S., highlighting that alliances and cooperative partnerships with reliable industry players are key to advancing domestic manufacturing growth.
Amid the operational expansion, Toyo remains involved in a U.S. trade investigation targeting the solar industry. On May 12, the U.S. government launched its fifth anti-dumping and countervailing duty (AD/CVD) probe into the sector, naming Toyo as a respondent. The investigation alleged the company evaded AD/CVD orders by exporting crystalline silicon PV modules and cells assembled in Ethiopia that utilized Chinese-origin wafers.
