U.S.-based solar energy company SunPower announced it's putting a hold on a $20 million plan to expand factories and create hundreds of new jobs in the U.S. until it can guarantee an exclusion from the new federal solar technology tariff, according to Reuters.

SunPower's decision to halt its growth in California and Texas follows President Trump Donald John TrumpBiden leads Trump by 36 points nationally among Latinos: poll Trump dismisses climate change role in fires, says Newsom needs to manage forest better Jimmy Kimmel hits Trump for rallies while hosting Emmy Awards MORE's announcement Monday that a 30 percent tariff would be placed on all imported solar technologies.

The administration said the decision would protect American manufacturing jobs but some solar companies, like SunPower, argued that it will hurt their bottom line and result in fewer jobs in the industry.

The tariff was seen as a major blow for America's $28 billion solar industry, which gets about 80 percent of its solar panel products from imports.

While SunPower is based in San Jose, Calif., the majority of its solar technologies are manufactured in the Philippines and Mexico.

"We have to stop the $20 million investment because the tariffs start before we know if we’re excluded,” SunPower Chief Executive Tom Werner told Reuters. “It’s not hypothetical. These were positions that we were recruiting for that we are going to stop.”

The tariff goes into effect on Feb. 7; however, the U.S. trade representative will not announce the rules for requesting an exclusion until Feb. 22.
