Concern is growing amongst the 800 employees of silicon wafer manufacturer Silico Solar which will be closing the 300MW facility in Puertollano at the end of this month until at least February 2012. Silico has blamed this on the adverse PV market conditions.

According to Spanish newspapers, the Silicio Solar board estimates that the decline of wafer prices within the last 12 months has been between 50 and 60%.

Puertollano is one of the solar industrial clusters of Spain. It is located near Ciudad Real in the Autonomous Region of Castilla-La Mancha.
