Since Japan’s feed-in tariff (FiT) was introduced (July 2012), its solar photovoltaic generation capacity installed has amounted to 3.9 GW. In all, approximately 4.086 GW of renewable power generation capacity was added since July 2012, including solar, wind, small and medium-sized hydroelectric, biomass, and geothermal.
Solar accounted for 90% of the renewable energy capacity added in that time period, according to the Japanese Ministry of Economy, Trade and Industry (METI), which sees this is an indication that its adoption of solar power is proceeding smoothly. 3.9 GW of growth over 16 months is at the top of the league. (This is an average of about a quarter of a GW per month).
According to PV-Tech:
The 3.9GW figure for installed solar energy capacity includes the figure for residential installations as one category and utility-scale or commercial use as a separate category. According to METI in the year between July 2012 and the same period of this year, around 1.521GW of residential solar was installed along with just under 2.4GW of commercial and utility scale.
As has been widely reported, the figure for completed utility-scale ‘mega solar’ projects in particular has not been matched by the amount of capacity put in the ground. The ministry’s figures reveal that the 2.4GW of installed commercial scale solar capacity is still dwarfed by the corresponding figure for approved utility scale projects – around 20.3GW. In contrast, for around 1.521GW of installed residential capacity, the approved figure was 1.751GW.
