Canadian Solar Opens $1 Billion Solar Cell Plant in Indiana to Boost US Supply Chain

Canadian Solar (NASDAQ: CSIQ) has opened a major solar cell manufacturing facility in Indiana, representing a nearly $1 billion investment aimed at strengthening the U.S. domestic solar supply chain. The plant is designed to address a critical production gap for solar cells, a key component that is predominantly manufactured in Asia.

Factory Details and Production

The facility, located in Jeffersonville, Indiana, is operated by CS PowerTech, Canadian Solar's U.S. manufacturing division. It is the first U.S. plant built to produce heterojunction solar cells, a technology known for higher efficiency compared to conventional designs.

Key figures for the new plant include:

• Investment: Nearly $1 billion
• Annual Capacity: 6 gigawatts (GW) of solar cells
• Employment: Over 1,200 workers once at full capacity
• Timeline: Expected to reach full production in early 2027

Strategic Importance for US Solar

This investment directly addresses a strategic vulnerability in the U.S. energy sector. While domestic assembly of solar panels (modules) has increased, the production of the cells themselves has lagged, forcing manufacturers to rely on imports. According to reports, China currently controls approximately 80% of the global solar supply chain.

The U.S. government has sought to onshore this production through policies like the 2022 Inflation Reduction Act, which provides significant tax credits for domestic clean energy manufacturing. Canadian Solar's new facility is a direct result of these incentives, marking a significant step toward building an end-to-end solar manufacturing ecosystem within the United States.
