Mass production

Global Solar Energy opened in 1996, and in 2008 finished another phase of development as it expanded its CIGS production to a new 40 MW facility in Tucson, Arizona and a second 35 MW facility in Berlin, Germany. The company expects to produce 20 megawatts of the films at the plant in 2008 before ramping up to 40 megawatts of capacity in 2009 and 140 megawatts by 2010. This makes Global Solar the largest full-scale manufacturer of CIGS thin-film photovoltaics.

Installations

Global Solar Energy operates the largest CIGS solar electric array in the world, a 750 kW system located at the company's manufacturing facility in Tucson. Part of the energy harnessed by this array is being purchased by the factory itself.
