Solar manufacturer Canadian Solar has signed a 7GW module supply agreement with EDF Renewables North America.

Canadian Solar will ship 7GW of its N-Type Tunnel Oxide Passivated Contact (TOPCon) modules to EDF from the manufacturer’s new factory in Mesquite, Texas. The facility will produce 5GW of modules annually at full capacity, with operations expected to begin near the end of 2023. The deal will run between 2024 and 2030.

Tristan Grimbert, president and CEO of EDF Renewables North America said: “The module supply agreement demonstrates our commitment to domestic sourcing and represents a pivotal step for EDF Renewables, enabling us to achieve key milestone dates and execute a schedule for the construction of our robust solar pipeline.”

TOPCon modules offer increased power output efficiencies, lower temperature coefficient and greater bifaciality compared with mono-PERC (passivated emitter rear contact) modules, Canadian Solar said. Last year, it predicted that TOPCon technology would account for around 30% of its total shipments in 2023 and would form the core of its production focus in the future.

TOPCon products – along with heterojunction technology (HJT) – are increasing their market share in the PV industry. Fellow Canadian module manufacturer Heliene announced plans last month for a 1.5GW/1GW TOPCon cell and module production facility in Minnesota, and Solar Module Super League (SMSL) member Trina Solar told PV Tech that it would specifically focus on the transition to n-type products in the future. Canadian Solar is also an SMSL member.

Shawn Qu, chairman and CEO of Canadian Solar said: “We are excited to work with EDF Renewables North America as we bring a stable supply of clean and reliable solar energy to the U.S. market, powered by solar modules made locally, under the backdrop of the Inflation Reduction Act (IRA).”

The US PV industry has been trying to decipher the domestic content guidance under the IRA recently, which proposes a 40% cost-based domestic production threshold for solar projects to be eligible for an extra 10% tax credit. This is likely impossible without domestic cell production.

Astronergy has introduced its latest module product series, ASTRO N7 and ASTRO N7s, both of which utilise rectangular wafers. ASTRO N7, based on the 210mm*182mm wafer, is specifically tailored for utility-scale systems. It features dimensions of 2382mm*1134mm and a 66-cell layout design that effectively lowers Voc and increases string size. This design feature significantly reduces tracker and cable costs, leading to a reduction in LCOE by 0.44% to 4.37% compared to 182mm-wafer TOPCon modules. Furthermore, ASTRO N7 incorporates advanced cell and module technologies such as laser-induced firing, super multi-busbar, light-redirecting film, and double-layer coating glass to enhance module power output and reliability. Join us to explore the latest advances in module technology and how they can improve module performance and learn about the economic advantage of rectangular-wafer modules and their benefits at a system level.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 8-9 October 2024 is our second PV CellTech conference dedicated to the U.S. manufacturing sector. The event in 2023 was a sell out success and 2024 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.
