Under the agreements, e-STORAGE, Canadian Solar's subsidiary specializing in the design, manufacturing, and integration of battery energy storage systems, will deliver 188 MWh DC to the Gaia project, located in Navarro County, and the 127 MWh DC Midpoint project in Hill County. Commissioning is scheduled for the third quarter of 2025 for both projects.

Canadian Solar Inc. (the "Company" or "Canadian Solar") (NASDAQ: CSIQ) today announced that it has executed three significant agreements with Sunraycer Renewables LLC ("Sunraycer"), an Annapolis, Maryland-based renewable energy platform. These include battery energy storage supply and commissioning agreements for two projects in Texas, as well as the purchase of up to 2 GWp of high-efficiency solar modules for various Sunraycer projects.

Under the agreements, e-STORAGE, Canadian Solar's subsidiary specializing in the design, manufacturing, and integration of battery energy storage systems, will deliver 188 MWh DC to the Gaia project, located in Navarro County, and the 127 MWh DC Midpoint project in Hill County. Commissioning is scheduled for the third quarter of 2025 for both projects.

Collectively, the two Texas energy storage projects will leverage over 60 SolBank 3.0 battery containers. SolBank 3.0 is e-STORAGE's latest proprietary energy storage solution, featuring high-density lithium-iron-phosphate cells, advanced battery management systems, and innovative liquid cooling thermal management systems. The design of the durable Solbank solution ensures the reliability and security required for large-scale projects in the demanding Texas environment.

Sunraycer's various upcoming projects will deploy up to 2 GWp of Canadian Solar's latest high-efficiency solar modules, with power outputs of up to 725 Wp. These modules offer up to 85% bifaciality and 23.3% module efficiency, along with low power degradation and high energy yield, effectively reducing the levelized cost of energy (LCOE) and system cost.

David Lillefloren, CEO of Sunraycer, commented, "As Sunraycer continues to grow and evolve its portfolio and pipeline, we are thrilled to be working with Canadian Solar as its preferred solar panel supplier for Sunraycer's entire current portfolio and with e-STORAGE on Sunraycer's initial tranche of energy storage projects. Canadian Solar is a proven market leader in renewable energy, and their equipment will help ensure Sunraycer is executing on its mission of delivering solar and battery projects that meet or exceed their performance goals while providing sustainable, clean, and affordable electricity to the grid."

Colin Parkin, President of e-STORAGE, stated, "We are excited to strengthen our presence in Texas with the Gaia and Midpoint projects. These two battery energy storage installations represent a significant contribution to Texas's growing renewable energy infrastructure, enhancing grid stability and supporting the state's clean energy transition. With over 6 GWh of energy storage solutions implemented or under construction across the U.S., e-STORAGE remains dedicated to delivering innovative, high-performance energy storage systems that drive the integration of renewables and ensure long-term grid reliability."

Thomas Koerner, Corporate Senior Vice President of Canadian Solar, added, "We are proud to work with Sunraycer on this up to 2 GWp multi-year partnership. This agreement is a testament to our mutual commitment to delivering and building high-quality solar and energy storage capacity in Texas and underscores Canadian Solar's ability to provide end-to-end solar generation and energy storage system solutions. It is a privilege to work with partners like Sunraycer, and we are grateful for the trust they have placed in Canadian Solar."
