The SolarWorld manufacturing plant in Hillsboro is cutting 120 jobs, according to the company.
An official filing Monday indicates 100 people will lose their jobs, at the end of August.
SolarWorld spokesman, Ben Santarris, says 20 more will be moved into other jobs at the Hillsboro facility.
Santarris says the company has reduced the solar panel processes done at the Hillsboro plant from four to just two.
"So, as a company, we will still do all four steps. In Hillsboro, we will do the last two steps. The cell production is the biggest step in terms of investment and in terms of employment. And that, and the next step - solar panel assembly - will continue in Hillsboro," Santarris says.
SolarWorld will continue to employ about 700 people -- including more than 600 in Hillsboro, according to Santarris.
The company blames the low price of Chinese solar panels. The U.S. Commerce Department put tariffs on the imported panels, last October, concluding that they were being sold at unfairly low prices.
