This development will probably put an end to plants like Ivanpah. The prices are even cheaper now, and Austin, Texas is planning on building a Gw plus plant.
PV Power Plants 2014 - Industry Guide: Falling prices, new markets
The installation costs are relatively low; even very large solar power plants can be planned and built in a short period of time. This is how the 148,000 solar modules at the 70-MW Solarpark Meuro in Meuro/Schipkau (Brandenburg, Germany) were installed in only four weeks. The maintenance costs, too, are relatively low, because a PV facility is a fixed installation, and has no moving parts. Therefore, problems may occur almost exclusively in the electrical system. These problems can generally be easily prevented (for example, through professional line layouts) or quickly remedied (for example, by exchanging damaged solar modules or defective converters).
Since sunshine is available everywhere, all that is required is open space and a mains supply point. A large number of solar farms were installed in Germany up until 2012, because they received favorable legislative supply subsidies, and the relatively dense network provides enough nearby mains supply points. This activity reached its peak in 2012 when the number of PV systems with more than 1 MW power accounted PV Power Plants 2014: The industry for a share of about 40 percent of the total market amounting to approximately 7,400 MWp. This corresponds to PV power of about 3,000 MW.
The amount of usable open space for PV was severely reduced due to amendments to the German Renewable Energy Sources Act (EEG). Meanwhile, the largest solar farms in the world have since been built in the USA and China. Open space is available in both of these countries in nearly unlimited quantities, however, a significant upturn began there as soon as system prices had dropped so much in recent years that commercially successful plants were possible even without promotions in the form of supply subsidies.
That and the fact they don't seem to work all that well. Ivanpah is still producing very low amounts of solar power. So low they almost don't register on the CA power grid monitor.
