Evergreen Solar

In 1984, inventor and entrepreneur Harold McMaster founded Glasstech Solar. After trying amorphous silicon, he shifted to CdTe and founded Solar Cells, Inc. in 1990. In February 1999, SCI was acquired by True North Partners, which then formed First Solar, LLC.At the end of 2009, First Solar had surpassed an energy power production rate of 1 GW and was the largest producer of PV cells in the world.The company is headquartered in Tempe, Arizona and has manufacturing facilities in Perrysburg, Ohio and Kulim, Malaysia.In July 2010, First Solar formed a utility systems business group to address the large-scale PV systems solutions market. Utility systems are now the company's core business focus, with a strategy to focus on markets that do not require subsidies to support the solar generation business.On April 17, 2012, First Solar announced it would restructure operations worldwide. This restructuring process included phasing out operations in Frankfurt , Germany and idling four production lines in Kulim, Malaysia. 30% of First Solar's workforce was laid off as a result of these actions, which were blamed on market volatility and reduced demand. Mark Widmar, the CFO of First Solar, said, "We need to resize our business to a level of demand that is highly reliable and predictable."On July 1, 2016, Mark Widmar was appointed CEO of First Solar. Previously he had been chief financial officer. Company founder and former CEO Mike Ahearn remains chairman of the board.
