Solarex became the nation’s largest, domestically owned solar-cell producer by 1994. It had 500 workers producing solar panels.

Solarex was acquired by Amoco, which sold a half-interest to Enron Corp in 1995. BP acquired both companies a few years later.

BP found it cheaper to shift production overseas and focus on solar installation. It closed the plant in 2010.
