Schott Solar is suspending one of its two concentrated solar power production lines in Albuquerque.
Schott says the suspension will mean laying off about 30 temporary agency employees.
The company blames slow growth in the North American market and a slowdown in the Spanish market.
Company spokesman Matthew Kraft in Elmsford, N.Y., says Schott had 370 employees in Albuquerque before the announced layoffs.
Schott produces photovoltaic panels and thermal receivers at its 200,000-square-foot Albuquerque plant, its flagship facility in North America.
The concentrated solar power modules or thermal receivers are used in large-scale solar power plant trough systems.
Officials say Schott's production of photovoltaic modules is not affected.
Mainz, Germany-based Schott AG opened the Albuquerque plant last year.
