Trina Solar has requested updates to its Sec. 337 of the Tariff Act investigation against various competitors producing TOPCon solar panel products. Trina in October 2024 requested the U.S. International Trade Commission (ITC) complete the investigation, which would direct U.S. Customs to stop infringing imports from entering the United States, against TOPCon solar imports from Runergy, Adani Green Energy and Canadian Solar.
Before the end of last year, Trina said in documents filed with the ITC that it had reached an agreement with Canadian Solar affiliate Recurrent Energy and wished to withdraw the complaint against Recurrent specifically. The investigation will continue against Canadian Solar. Separately, Trina said it met with Adani and wishes to add Mundra Solar PV (an Adani subsidiary) as another company under investigation. Trina intends to continue the complaint against Runergy, Adani and now Mundra.
This Sec. 337 investigation request originates with TOPCon patent infringement claims filed by Trina against the companies. Trina claims that Runergy and Canadian Solar are infringing on two of Trina’s patents (Nos. 9,722,104 and 10,230,009). While a Sec. 337 investigation is ongoing, the patent infringement cases are stayed.

January 8, 2025 update: SPW incorrectly reported that the complaint against Canadian Solar was withdrawn. Instead, only one of Canadian Solar’s affiliates (Recurrent Energy) was removed from the complaint.
