U.S. President Joe Biden will take executive action to boost the U.S. solar sector, seeking to revive clean energy projects stalled by a trade dispute and bolster domestic manufacturing so the nation’s climate efforts are less reliant on foreign suppliers.

Biden plans to invoke the Defense Production Act to provide support for U.S.-made solar panels, said people familiar with the matter, who asked for anonymity to discuss private details before a public announcement expected as soon as Monday.

At the same time, the president is set to announce a two-year halt in new solar tariffs, which would allow domestic project developers to continue using foreign-made equipment while U.S. manufacturing ramps up, two of the people said.
