When will grid parity for concentration photovoltaics be reached?

clipped from www.leonardo-energy.org Grid parity - the point where the cost of generating electricity by solar systems equalises the average (wholesale) price of generating electricity by means of conventional methods - is the Holy Grail for the photovoltaics industry. For concentrating photovoltaics in the sunniest locations in the world, this point is not far off. The most optimistic estimates put it at 2011, whereas pessimists expect we'll have to wait as long as 2020. Therefore, a prediction market at Leonardo Visions to build a consensus view among Leonardo ENERGY users on this important issue.
