Solar in Tennessee

FYI
Tennessee has the world largest manufacture of solar (photovoltaic) panels in Memphis: Sharp Solar (albeit they sell @ 75% of them outside the US!). In 2008 that company was joined by Shoals Technologies, Inc. which established headquarters and manufacturing operations for solar panels in Gallatin, TN and Hemlock Semiconductor announced plans to build a $1.2 billion (with a B) facility for manufacture of ultra pure polycrystalline silicon in Clarksville, TN in December 2008 (polycrystalline silicon is used as a semiconductor material in solar panels). A competitor of Hemlock, Wacker Chemi AG of Munich, Germany announced plans to build a $1 Billion dollar (B again) polycrystalline silicon operation in Cleveland, TN in early 2009.

The word Photovoltaic is a combination of the Greek word for Light and the name of the physicist Allesandro Volta. It identifies the direct conversion of sunlight into energy by means of solar cells.>>more

Solar cells are composed of various semiconducting materials. Semiconductors are materials, which become electrically conductive when supplied with light or heat, but which operate as insulators at low temperatures.
