Dr Andrew Blakers (Director of the Centre for Sustainable Energy Systems and the ARC Centre for Solar Energy Systems at the Australian National University): "
According to the Clean Energy Council report, PV installation rates have risen from about 20 Megawatts (MW) total capacity nationally in 2008 to about 800 Megawatts in 2011. Expected demand will fall in 2012 – perhaps to about 500 MW – because of the end of high feed-in tariffs. But, as mentioned, the economics of PV are now so attractive that long-term, rapidly rising demand is likely. Putting it into context, we’d need about 3,000 MW of PV to be installed each year to achieve 50% of electricity from PV in 2040 – obviously a feasible proposition given this year’s performance."
