Sanyo’s solar division is closing a silicon wafer and ingot manufacturing facility in Carson, Calif., laying off 140 workers, company officials confirmed Monday.

But a spokesman said the move doesn’t portend a similar fate for the company’s 200-employee manufacturing operation in Salem.

“It doesn’t change anything for Salem at all,” said Aaron Fowles, a Sanyo spokesman.

Fowles said the California plant was using old machines to make an old-style of solar components.

“The ones we make in Oregon are the newer style,” Fowles said.

The layoff amounts to about 40 percent of Sanyo Solar’s U.S. solar manufacturing workforce.
