By GridDigest Editorial · August 4, 2026 · synthesized from 6 sources

CS PowerTech has officially opened phase one of its solar cell manufacturing plant in Jeffersonville, Indiana, with targeted capacity exceeding 6 GW annually at full buildout.
CS PowerTech, a subsidiary of Canadian Solar (NASDAQ: CSIQ), has inaugurated the first phase of a heterojunction technology solar cell manufacturing facility in Jeffersonville, Indiana, marking a significant expansion of domestic photovoltaic production capacity in the United States.
Facility Details and Location
The plant is situated at the River Ridge Commerce Center in Jeffersonville, Indiana. At full buildout, the facility is targeted to exceed 6 gigawatts of annual solar cell production capacity. The technology employed is heterojunction technology, commonly referred to as HJT, a cell architecture associated with high conversion efficiency. Canadian Solar has described CS PowerTech as the largest silicon PV solar manufacturer in the United States.
Workforce and Economic Impact
The Jeffersonville facility is expected to employ more than 1,200 workers once fully operational. Company materials framed the project in terms of strengthening domestic manufacturing, improving supply-chain resilience, and contributing to broader U.S. energy production goals. The plant's opening represents a phase-based ramp, with the current announcement covering only the first stage of a larger planned buildout.
Industry Context
The opening comes as domestic solar manufacturing has drawn increased attention from both policymakers and industry players seeking to reduce reliance on overseas cell and module supply chains. HJT technology is considered a premium segment of the crystalline silicon solar market, and large-scale domestic HJT cell production at this level is notable within the North American manufacturing landscape. Canadian Solar, headquartered in Kitchener, Ontario, operates CS PowerTech as a U.S.-based manufacturing entity under its corporate structure.
