As per the contract, the German company would supply silicon wafers worth over $1.2 billion (Rs 4,800 crore) to SSSPL.
According to SSPL vice president, Ravi Surapaneni, the company has entered into the contract so as to ensure that there would be no disruption in the production of its solar PV modules on account of scarcity of silicon wafers.
SSPL offers its products and services to solar PV module market worldwide.
SolarWorld AG chairman and chief executive officer, Frank H Asbeck, stated that through the wafer contract the company was securing the capacity utilisation of the first expansion stage of its new wafer factory in Freiberg located in the German state of Saxony.
The capacity of the factory was being increased to 750 Mw by adding 250 Mw by the end of 2009.
