California Solar Initiative in Comparison To Japan's FIT

By April 18, 2013 No Comments

California Solar Initiative (CSI), together with Japan’s solar feed-in-tariff (FIT) program, have been widely praised as successful models for incentivizing solar installations.

Overall, although the Japanese program is larger in scale with a longer history, the CSI has been growing more rapidly with less incentives for the last few years. Between the first quarter of 2010 and the fourth quarter of 2012, the CSI quarterly installation grew at a compounded quarterly growth rate (CQGR) of 7.1%, while the rate was just 4.8% for Japan. With the higher growth rate, the installed system cost has been shrinking more rapidly in California. During the same period, the CSI quarterly average installed-system cost fell by a CQGR of 3.5%, compared to 2.8% for Japan.
