In a dramatic display of the power feed-in tariffs have in driving markets, Italy installed more solar photovoltaics (PV) in 2009 than the entire US. Moreover, within the first quarter of 2010, Italy's total installed solar PV capacity was expected to exceed that of the US.
Italy installed 720 MW of solar PV in 2009, nearly all of that on rooftops. In contrast, the US installed 435 MW during the same period, according to a draft report by the Interstate Renewable Energy Council (IREC).
Italy introduced a system of feed-in tariffs for solar PV in February, 2007 after concluding that the previous program of Tradable Green Certificates was not delivering the results desired.
By the end of 2007, Italy had installed five times more solar PV than in the previous year. Despite numerous bureaucratic roadblocks, the solar industry took off in 2008 and installed nearly 350 MW, then a record-breaking number. Solar PV installations have been doubling since then and are expected to reach 1,500 MW in 2010.
