Homeland Security officers descended on a factory and office this week.
The facilities are owned by one of the world’s largest solar panel makers: China’s Jinko Solar Holding company.
A DHS spokesperson explained that search warrants were executed in Florida and California on Tuesday. He noted they’re part of an ongoing federal investigation, but didn’t give details.
Jinko is based in Shanghai but operates a solar panel factory in Jacksonville, Florida, and a sales and operations office in San Francisco.
The company is one of few global solar manufacturers that have set up domestic production in recent years. Most U.S. solar panels are imported from Asia.
