The EPIA wants 12% of EU electricity consumption to come from photoelectrics by 2020! That's roughly 425 TWh.
Assuming a ballpark thumbrule of 1 TWh per GW of installed capacity you'd need to install 425 GW in the next 10 years. If you assume a steady 35% YoY growth rate Europe will need to consume half of the yearly worldwide production for the next decade. That is an ambitious goal.
