Canadian Solar forms joint venture to bring U.S. solar operations in-house, reshoring production and cutting trade risks.

Canadian Solar Inc. announced on December 1, 2025, it will form CS PowerTech, a new joint venture with a 75.1% controlling stake, to regain direct oversight of its U.S. solar and energy storage operations. The company will acquire key overseas assets from its subsidiary CSI Solar for about $50 million, aiming to reshore manufacturing, reduce trade risks, and support domestic job creation. The move, pending approvals, is part of a broader strategy to strengthen North American supply chains and expand joint ventures in clean energy.
