Canadian Solar Ships 3.7 GWh of Battery Storage in Q2 2026

en.Wedoany.com Reported - Canadian Solar released its Q2 2026 results for the period ending June 30 on August 27. Battery energy storage system shipments reached 3.7 GWh in the quarter, up 73% year-over-year from 2.2 GWh in the same period last year.

Headquartered in Ontario, Canada, the company is a vertically integrated manufacturer of solar photovoltaic (PV) and battery energy storage systems (BESS). Quarterly total net revenue was $1.2 billion, at the high end of the $1.0–1.2 billion guidance range, up 12% sequentially but down 29% from $1.7 billion in Q2 2025. Gross margin was 13.9%, less than half of the 29.8% recorded in the year-ago quarter. Net loss was $77 million.

Solar module shipments fell 60% year-over-year to 3.1 GW, the lowest level since Q2 2020 (when shipments were 2.9 GW). As manufacturing capacity continues to expand, particularly in the United States, the company expects module shipments to recover in the third quarter. Q3 guidance calls for 3.5–3.8 GW of solar modules, 3.4–3.8 GWh of battery storage, revenue of $1.3–1.5 billion, and gross margin of 13.5%–15.5%. For full-year 2026, the company's U.S.-only shipment guidance is 6.5–7 GW of solar modules and 4.5–5.5 GWh of battery storage.

Energy storage subsidiary e-STORAGE posted quarterly revenue of $426 million, with contracted backlog of $3.5 billion at period end. Operating projects under long-term service agreements (LTSAs) total 34 GWh. Of the 3.7 GWh shipped in the quarter, 471 MWh was deployed in Canadian Solar's internal projects, with the remaining 3.3 GWh recognized as revenue.

Project development business Recurrent Energy generated quarterly revenue of $117 million, gross profit of $36 million, gross margin of 30.7%, and an operating loss of $19 million. The company has approximately 6 GW of PV projects under construction and a 15.5 GW opportunity pipeline across North America, EMEA, and Asia-Pacific. BESS projects currently under construction in North America total 600 MWh, with an additional 4,378 MWh in backlog, 7,841 MWh in advanced pipeline with grid interconnection secured, and 71,238 MWh in early-stage pipeline.

This earnings report is the first since founder Dr. Shawn Qu stepped down as CEO. His successor, Colin Parkin, previously led e-STORAGE and was introduced by Dr. Qu during the Q1 2026 earnings call. Dr. Qu now serves as Chairman and Chief Technology Officer. Canadian Solar derives nearly all of its revenue from its manufacturing segment (CSI Solar, of which e-STORAGE is a subsidiary). Parkin noted that manufacturing shipments met expectations while battery storage operations slightly exceeded them, and that the company is responding flexibly to global macroeconomic uncertainty. Manufacturing remains the key driver of financial performance and a strategic priority. The manufacturing segment posted quarterly revenue of $1.1 billion, gross profit of $131 million, gross margin of 11.9%, and an operating loss of $49 million, which Parkin attributed to higher unit shipping costs and line ramp-up expenses. The storage business delivered projects across North America, EMEA, Asia-Pacific, and Latin America this quarter and is expanding rapidly worldwide.

Parkin emphasized that vertical integration is a strategic advantage in the storage market, noting that the company's value extends beyond supplying battery containers: Canadian Solar manufactures its own cells, designs the SolBank platform, integrates power conversion and proprietary energy management controls, provides EPC and commissioning services, and supports customers through long-term service agreements. Since 2023, the company has shifted from a white-label model to self-manufacturing BESS, including cells.

Dr. Qu presented the technology roadmap during the call. On the solar side, the company plans to mass-produce and optimize next-generation heterojunction (HJT) and TOPCon cell architectures by 2028, and in the same year begin mass production of premium tunnel oxide passivated back contact (TBC) cells primarily targeting the residential market. Perovskite tandem cells targeting commercial shipments by 2030 have the potential to break through the 30% module efficiency range, which Dr. Qu described as the company's "ultimate efficiency frontier."

On the storage side, Canadian Solar is exploring a solid-state transformer solution rated at 2.5 MW, converting 34.5 kV AC to 800 V DC with conversion efficiency exceeding 98.5%. This solution could potentially replace power conversion systems (PCS) and be integrated directly into the BESS platform, potentially enabling BESS to enter long-duration energy storage (LDES) applications and meet demanding environmental requirements at a lower levelized cost of storage (LCOS).

The current SolBank 3.0 uses lithium iron phosphate (LFP) chemistry with 314 Ah cells, delivering 5 MWh in a standard 20-foot container. The next-generation SolBank 4.0 uses 588 Ah LFP cells in the same footprint, increasing energy density by 25% to 6.25 MWh, with e-STORAGE beginning shipments in 2027. The company states that its power electronics scale is expanding in tandem with battery systems, with solutions transitioning from air-cooled versions to liquid-cooled medium-voltage (MV) skids: Skid 2.0 integrates 32 × 450 kW inverters, delivering 14.4 MW in a 40-foot layout.

The company is also validating SolBank Na, a sodium-ion containerized BESS platform expected to deliver more than 15,000 cycles, featuring abundant raw materials, simplified cooling requirements, and lower thermal runaway risk. The storage technology roadmap also includes a high-capacity product for AI data center server rooms, providing millisecond-level energy management. Dr. Qu stated that these technological advancements will unify the solar and storage segments, advancing Canadian Solar's vision as a comprehensive energy technology provider.
