New research conducted by NPD Solarbuzz and featured on their blog this past week shows that Japanese solar photovoltaic “PV” installations have now passed 10 GW for cumulative PV capacity, only the fifth country to reach the mark. Of the previous four — Germany, Italy, China, and the US — the latter two only reached the milestone within the past few months, highlighting Japan’s achievement.
Japan Hits 10 GW Milestone
ota-city-solar-power-japanWriting on the Solarbuzz website, NPD Group Vice President Finlay Colville pointed to three landmark high-points along Japan’s solar PV leadership, highlighting not only their recent 10 GW milestone, but also that Japan was the first country to reach the 1 GW of cumulative solar PV back in 2004. This was helped along by;
•The Ministry of Economy, Trade and Industry (METI) launched a subsidy program for residential PV systems as far back as 1994. Initially, the subsidy covered 50% of the cost of PV systems. The budget for FY 1994 was 2 billion Yen.
•Until 2005, Japan had the largest installed PV capacity of any country in the world. This early leadership position was achieved through a well-managed set of programs, coupled with attractive market incentives.
•The early growth of the Japanese PV market was a strong factor in establishing Japanese manufacturing as the first dominant force in the solar PV industry. Manufacturers that benefited from the first phase of government initiatives include several of the companies that are now leaders in the domestic PV industry revival: Sharp, Sanyo and Kyocera.
In the Face of Fukushima
Sadly, another factor that has to be considered in Japan’s recent increase in solar PV installation must be the fallout from the Fukushima Daiichi nuclear ‘disaster’ which followed the massive earthquake and subsequent tsunami on March 11, 2011. Corollary evidence might suggest that the launch of the feed-in tariff program in July 2012 which was focused t
