[Its a god-damned Revolution…. TB]
In 2011, the solar industry saw global oversupply drive PV prices to record lows, with crystalline silicon (c-Si) module prices falling from $1.80 per watt at the start of 2011 to $0.90 per watt by year’s end.
High purity silicon (polysilicon), the key feedstock for c-Si modules, played only a minor role in this price collapse, as over 80 percent of polysilicon is sold via long-term contracts, and the pricing on these contracts moved little for most of 2011. However, oversupply in the polysilicon market pushed the spot price of silicon down from $80 per kilogram in late March 2011 to under $30 per kilogram in December, representing more than a 60 percent drop. This substantially lower spot price gave silicon customers (i.e., wafer manufacturers) the leverage to renegotiate contract pricing downward, and this will result in much lower realized silicon average selling prices (ASPs) in 2012.
