Canadian Solar has secured a framework agreement to provide Sol Systems with a significant supply of modules from its newly ramped Texas module factory.

Canadian Solar Inc. (the "Company" or "Canadian Solar") (NASDAQ: CSIQ) and Sol Systems, a leading renewable energy company based in Washington, D.C., announced today a partnership to scale new solar module production and procurement in the United States. Canadian Solar has secured a framework agreement to provide Sol Systems with a significant supply of modules from its newly ramped Texas module factory.

Under the partnership, Canadian Solar will supply its latest high efficiency N-Type TOPCon (Tunnel Oxide Passivated Contact) solar modules to support Sol Systems' project pipeline in the U.S. between 2024 and 2025.

Highlighting Canadian Solar's competitive advantage, Dan Diamond, Chief Construction Officer of Sol Systems, said, "We are thrilled to partner with Canadian Solar to scale the U.S. solar module manufacturing industry and create new American manufacturing jobs. Canadian Solar's TOPCon modules boost project economics through higher yields, smaller site footprint and lease costs, and lower balance of system costs. We were very impressed with the state-of-the-art facility during our visit to the Texas factory in December."

Thomas Koerner, Senior Vice President of Canadian Solar, commented, "Our cost-competitive TOPBiHiKu7 bifacial TOPCon module has received overwhelmingly positive market feedback, as it gives project developers the secure and long-term module supply they have been looking for. We are pleased to be the partner of choice for a key market leader like Sol Systems." He added, "We are proud to have ramped up our Texas facility in record time and started module production last December. We are encouraged by the significant interest in and demand for these locally made products."
