In January 2018, President Donald Trump slapped tariffs on imported solar panels despite protests from much of the industry, sending jobs in one of the nations fastest-growing employment engines tumbling for the following two years.

Now the solar industry is asking President-elect Joe Biden to cut short what was widely seen as Trumps biggest blow to solar energy during his single term.

On Tuesday, Solar Energy Industries Association, a trade group representing more than 1,000 companies, said it wants the Biden administration to revoke the four-year tariffs a year early.

The White House should have the legal authority to end the import fees unilaterally, despite the fact that courts blocked Trumps efforts to amend his own tariffs to remove an exemption for bifacial panels, photovoltaics that harvest energy from the sun on both sides of the equipment.

Revoking an exclusion already granted and removing tariffs are two very different procedural policies, Abigail Ross Hopper, SEIAs president and chief executive, said during a press call Tuesday morning.

We are asking the president-elect to remove those tariffs a year early because we dont think it was having the policy objective at least our current president was looking for, she added.
