Canadian Solar subsidiary opens 6 GW solar cell factory in Indiana

A Canadian Solar subsidiary, CS PowerTech, has started production at a new solar cell factory in Jeffersonville, Indiana. The plant makes heterojunction (HJT) bifacial solar cells, a type of high-efficiency cell that captures sunlight on both sides of the panel. This first phase is part of nearly $1 billion in planned investment at the site, and the company expects the facility to eventually support more than 1,200 manufacturing and technical jobs once it's fully running. A second phase of expansion is expected to begin before the end of the year.

The cells made in Indiana will be shipped to CS PowerTech's panel assembly plant in Mesquite, Texas, giving the company a more U.S.-based supply chain for the solar panels it sells. Company leaders say this matters because rules around "domestic content" — requirements that solar equipment include a certain share of U.S.-made parts to qualify for certain incentives — are shaping how solar projects get built across North America.

For homeowners, this news doesn't change any rebate or incentive program directly. But it points to more solar panels on the market made with U.S.-manufactured cells, which could matter down the road if you're comparing panels for a rooftop solar installation and want to know whether they qualify for domestic-content-based incentives. It's also a sign that solar manufacturing capacity in the U.S. is growing, which over time can affect panel availability and pricing.
