KITCHENER, ON and JEFFERSONVILLE, Ind., July 24, 2026 /PRNewswire/ -- CS PowerTech Inc., a subsidiary of Canadian Solar Inc. (NASDAQ:CSIQ) and the largest silicon PV solar manufacturer in the U.S., today announced the official opening of the first phase of its flagship PV cell manufacturing facility at the River Ridge Commerce Center in Jeffersonville, Indiana. The Jeffersonville PVCells facility is a cornerstone of CS PowerTech's U.S. manufacturing platform, reshoring critical advanced manufacturing, strengthening U.S. supply-chain resilience, and supporting America's energy security.

Jeffersonville PVCells is the first American PV cell facility designed to produce industry-leading heterojunction (HJT) bifacial N-type solar cells.

At full capacity, the facility is expected to produce more than 6 GWp annually, support more than 1,200 skilled manufacturing, engineering, and technical jobs in Southern Indiana, and represent nearly $1 billion in local investment.

Rusty Schmit, President of CS PowerTech Inc., said, "Jeffersonville is a cornerstone of our strategy to build one of North America's most advanced energy manufacturing supply chains. This facility will produce next-generation HJT solar cells, support domestic manufacturing, and ultimately strengthen grid reliability as our customers deploy the products. We are proud to invest in Indiana's workforce and work with regional partners to build a long-term center of excellence for solar technology and advanced manufacturing."

Colin Parkin, Chief Executive Officer of Canadian Solar Inc., added, "The Jeffersonville facility demonstrates our commitment to scaling one of the world's most advanced solar cell technologies in the United States. HJT technology is critical for the next generation of high-efficiency, high-performance solar modules, and this plant gives CS PowerTech the ability to deliver leading technology, improved energy yield, and long-term value for customers while strengthening domestic advanced manufacturing."

Governor Mike Braun, stated, "CS PowerTech's investment strengthens Indiana's position in advanced manufacturing, creates good-paying jobs for Hoosiers in the area, and reinforces our role in building the technologies that will continue to power America's future."

Indiana State Senator Chris Garten, stated, "CS PowerTech's investment in Jeffersonville is a major win for Southern Indiana. This facility will create over a thousand high-quality jobs, strengthen our advanced manufacturing base, and help position our region as a leader in the technologies that will power America's future."

Indiana State House Representative Wendy Dant Chesser, said, "Indiana's manufacturing workforce is second to none. We welcome CS PowerTech's investment at River Ridge and are excited to launch Southern Indiana into the lead for advanced energy manufacturing and technology."

Jeffersonville Mayor Mike Moore, stated, "CS PowerTech is an important part of Jeffersonville's growth story. This investment reflects the strength of our workforce and our city's position as a premier destination for advanced manufacturing."
