"The PV industry is at a crossroads," said EPIA President Ingmar Wilhelm. "Whilst European markets have always outpaced home production, this will presumably no longer be the case in the years to come. New markets around the world will have to be opened up to drive PV development in the coming decade just as Europe accounted for it during the last decade."
The EPIA sees a total growth of 27.7 GW extending the overall installed capacity (in the world) from 39.7 GW in 2010 to 67.4 GW at the end of 2011. This equals a growth of almost 70% in 2011.
