According to the Ministry of Economy, Trade and Industry, the nation has approved approximately 21,090MW of renewable energy projects which include 18,681MW of non-residential solar.

Apart from solar, the country has also approved wind and biomass projects, reports the bloomberg.com.

Japan has outlined plans to boost its solar power capacity this year, as it is aimed at diversifying its energy sources after the nuclear disaster in Fukushima in 2011.

The solar tariff that is paid by utilities has been reduced from JPY 42 per KWh to JPY37.8 (39 cents) per KWh for 20 years.

The renewable energy producers in the country must secure approval from both the trade ministry and local utilities to participate in the incentive program.
