Rapid uptake Grid parity

photovoltaics starting compete in places without subsidies. shi zhengrong has said that, of 2012, unsubsidised solar power competitive fossil fuels in india, hawaii, italy , spain. pv system prices decline inevitable subsidies end. solar power able compete without subsidies against conventional power sources in half world 2015 . in fact, recent evidence suggest photovoltaic grid parity has been reached in countries of mediterranean basin (cyprus).

predictions power source becomes self-supporting when parity reached appear coming true. according many measures, pv fastest growing source of power in world:

for large-scale installations, prices below $1.00/watt common. in locations, pv has reached grid parity, cost @ competitive coal or gas-fired generation. more generally, evident that, given carbon price of $50/ton, raise price of coal-fired power 5c/kwh, solar pv cost-competitive in locations. declining price of pv has been reflected in rapidly growing installations, totalling 23 gw in 2011. although consolidation in 2012, firms try restore profitability, strong growth seems continue rest of decade. already, 1 estimate, total investment in renewables 2011 exceeded investment in carbon-based electricity generation.

the dramatic price reductions in pv industry have been causing number of other power sources become less interesting. nevertheless, there remains widespread belief concentrating solar power (csp) less expensive pv, although suitable industrial-scale projects only, , has compete @ wholesale pricing. 1 company stated in 2011 csp costs $0.12/kwh produce in australia, , expects drop $0.06/kwh 2015 due improvements in technology , reductions in equipment manufacturing costs. greentech media predicts lcoe of csp , pv power lower $0.07–$0.12/kwh 2020 in california.
