en.Wedoany.com Reported - Canadian Solar has commenced trial production at its flagship heterojunction solar cell factory in Jeffersonville, Indiana, in April 2026, targeting commercial operation by July 2026. The news was disclosed in the first quarter 2026 financial report released on May 14.

The first phase of the Jeffersonville facility has a nameplate capacity of 2.1 GWp, and once fully ramped up, it will become one of the first commercial-scale heterojunction solar cell factories in the United States. Driven by strong customer demand, Canadian Solar has already planned to further expand the factory from its initial 5 GWp target, with ongoing installation and commissioning of additional production lines continuing through 2026.

The second phase of the project is expected to begin trial production in early 2027, adding 4.2 GWp of annual capacity. Upon completion of both phases, Canadian Solar's total U.S. solar cell manufacturing capacity will reach 6.3 GWp. The Indiana project is part of Canadian Solar's broader U.S. manufacturing strategy, as the company is also expanding its solar module assembly facility in Mesquite, Texas, from 5 GWp to 10 GWp, with completion planned for the second half of 2026.

Dr. Shawn Qu, Executive Chairman and Chief Technology Officer of Canadian Solar, stated that the Jeffersonville factory is a critical node in strengthening the U.S. solar supply chain, reflecting the company's deepening manufacturing footprint in the United States. The growth in U.S. solar cell manufacturing capacity comes against a backdrop of expanding utility-scale demand in key markets like Texas, where developers such as Sunraycer Renewables are advancing large portfolios of solar and battery energy storage projects that have recently secured financing support.
