A decision is due next week on whether or not SolarCity’s Silevo modules should be included in the scope of US trade duties on Chinese solar products.

SolarCity asked the Commerce Department to rule that its Triex products are outside the scope of the order, triggering a response from SolarWorld, the petitioner in the trade case.

SolarWorld has argued that as Silevo’s Triex cell has a crystalline silicon substrate and a p-n junction, it should be included in the scope of the case. SolarCity argues that while the cell may have a c-Si substrate, at its heart it is an amorphous silicon thin-film product.

“They have advertised these products as ‘quality c-Si modules’ and its website states that Triex cells have an n-type crystalline substrate,” SolarWorld’s lawyer Tim Brightbill of WileyRein told PV Tech. “So using their own claims these are crystalline and covered. The scope also covers any product with a ‘p-n junction formed by any means’. They have a p-n junction so they are covered and the same is said of other bifacial and hybrid cells,” he added.

Thin-film products, including First Solar’s and Solar Frontier’s, are excluded from the scope of US duties entirely. A ruling on the request by the Department of Commerce is scheduled for March 17.

“We hope that this ruling will encourage SolarCity and Silevo to manufacture their cells and modules in the US rather than to import dumped and subsidised products from China. Currently Silevo and Solarcity appear to be highly dependent on dumped and subsidised Chinese imports,” claimed Brightbill.

A 1GW Silevo production facility is under construction in Buffalo, New York. A recent filing by SolarCity indicated that there is a delay with the facility due to the lead time of equipment and tools. There is no indication that the facility will include wafer manufacturing.

Brightbill argued that the origin of wafers used by the new Riverbend facility will be important.

“If they bring in plain wafers, that's ok. If they have done anything to the wafer [in China] then it is a partially manufactured cell and they would have the duties [applied].”

Brightbill claimed that any cells imported from China for Silevo modules would have to pay the China-wide duty rates from the 2012 case as the company was not assigned an individual rate. The amended China-wide anti-dumping rate is 238.95%.

‘Inferior products’

A spokesman for SolarCity questioned SolarWorld’s motivation.

“SolarWorld offers an inferior product, and are trying to protect their own selfish interests by attempting to make other solar technology more expensive for customers,” the company said in an emailed statement to PV Tech.

“The Silevo modules are manufactured with a c-Si substrate, but the substrate is not what defines a cell. In production, numerous a-Si thin film layers are applied to the substrate to create an a-Si thin-film product, which is outside the scope of the Orders,” the company reiterated. 

“SolarCity acquired Silevo in part to significantly expand solar manufacturing in the US – we’ve already moved Silevo’s R&D and pilot manufacturing to California from China and we’re building the largest solar manufacturing facility in the Western Hemisphere in New York.”

While a decision is due on March 17, the deadline is flexible if the department decides it needs more time.

PV Tech has been running PV ModuleTech Conferences since 2017. PV ModuleTech USA, on 16-17 June 2026, will be our fifth PV ModulelTech conference dedicated to the U.S. utility scale solar sector. The event will gather the key stakeholders from solar developers, solar asset owners and investors, PV manufacturing, policy-making and and all interested downstream channels and third-party entities. The goal is simple: to map out the PV module supply channels to the U.S. out to 2028 and beyond.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 13-14 October 2026 is our third PV CellTech conference dedicated to the U.S. manufacturing sector. The events in 2023, 2024 and 2025 were a sell out success and 2026 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.
