CS PowerTech, the U.S. manufacturing subsidiary of Canadian Solar, has inaugurated the first phase of its solar cell manufacturing facility in Jeffersonville, Indiana.

Once fully built out, the facility is expected to have an annual production capacity of more than 6 GW.

This marks the company’s entry into domestic solar cell production in the U.S.

The facility, located at the River Ridge Commerce Center, is designed to manufacture heterojunction (HJT) bifacial N-type solar cells.

CS PowerTech said the Jeffersonville facility, together with its solar module manufacturing facility in Mesquite, Texas, will create a more localized and vertically integrated manufacturing supply chain for solar products in the U.S.

The company said the project represents nearly $1 billion in local investment and is expected to support more than 1,200 manufacturing, engineering, and technical jobs in Southern Indiana.

The first phase of the facility will ramp up to full production over the next several months, and the company expects to begin work on the second phase of the expansion before the end of the year.

CS PowerTech operates solar module manufacturing in Mesquite, Texas, and solar cell manufacturing in Jeffersonville, Indiana.

The company said its U.S. manufacturing operations employ more than 3,000 people, and its parent company, Canadian Solar, is headquartered in Kitchener, Ontario.

Canadian Solar has delivered nearly 177 GW of solar modules globally and shipped more than 20 GWh of battery energy storage systems through its e-STORAGE subsidiary as of March 31, 2026. As of May 8, 2026, it had a contracted backlog of $3.5 billion.

The company has developed, built, and connected approximately 12.2 GW of solar power projects and 6.4 GWh of battery energy storage projects globally. Its geographically diversified project development pipeline includes 24 GWp of solar and 81 GWh of battery energy storage capacity in various stages of development.

In the first quarter of 2026, Canadian Solar’s revenue declined 10% year-over-year to $1.08 billion from $1.20 billion. The company attributed the revenue drop to lower solar module sales, which were partially offset by higher battery energy storage sales.

In April 2026, the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office invalidated all claims by Trina Solar on two TOPCon (Tunnel Oxide Passivated Contact) solar cell patents against certain subsidiaries of Canadian Solar.
