In April 2025, Canadian Solar’s subsidiary, CSI Solar Co., Ltd., acquired Endurans Solar, a U.S. company specializing in backsheet materials. The strategic acquisition aims to enhance Canadian Solar’s performance and reduce its solar module manufacturing costs.
This move is part of the company’s ongoing expansion, which was previously fueled by a $200M investment for growth in the renewable energy sector, as reported by PVKnowhow.
The deal reflects a broader trend in the solar industry toward vertical integration, a strategy that helps companies optimize their supply chains and improve overall efficiency. Backsheets are a critical component in solar panels, protecting sensitive internal circuitry from environmental factors. This acquisition gives CSI Solar greater control over the quality and cost of this essential material.
Such strategic moves are particularly relevant as the solar landscape evolves, with more projects using panels manufactured in specific regions. SolarBank, for example, recently announced a new solar energy project using panels manufactured in the United States.
The acquisition could also impact Canadian Solar’s manufacturing strategies in Canada, where the solar panel manufacturing sector is growing and attracting significant market attention—a trend highlighted in PVKnowhow’s Canada Solar Panel Manufacturing | Market Insights Report.
