Japanese Economy, Trade and Industry Provincial Office of Natural Resources and Energy announced on March 13, 2013 Japan put into operation in April 2012 to the end of December, according to the July 2012 acquisition of the fixed price system identified renewable energy. 

This period of operational renewable energy equipment capacity totaled 1.178 million kW (1.178GW), basically the same as last year, but during which access to certified equipment capacity a total of 5.236 million kW (5.236GW), significantly more than the capacity of functioning equipment . 

Resources and Energy explained, also need some time to get identified to operationalize the "some tens of thousands of kilowatts of large-scale systems to be 2 to 3 years to start". Even so, from the point of view of promoting the use of renewable energy, the fixed price of the acquisition system has played a significant role. 

grid tie inverter power generation accounted for 95% of Japan in April 2012 to the end of December to operationalize renewable energy equipment solar power generation system. Natural Resources and Energy installed solar power systems throughout Japan in April 2012 to the end of December 1,119,000 kW (1.119GW), renewable energy other than solar power system for 59,000 kW solar power system is approximately 1/20 . 

Solar power system operational during this period, the residential use of 911,000 kW and non-residential uses 208,000 kW residential use still accounts for more than half. However, it can be seen from the identified equipment capacity, this situation is changing. 

Identified over six months before the cumulative installed capacity from July 2012 to the end of December, renewable energy identified a total of 5.236 million kW, of which 4,704,000 kW solar power system (4.704GW) in before the end of March 2012 Japan's PV inverter power system is the cumulative installed capacity of approximately 4.8 million kW (4.8GW), only the identification of six months has basically reached the sum of the past 20 years, the total installed capacity. 

, The identified solar electric system in the residential use of 847,000 kW and non-residential uses to 3,857,000 kW. Earlier, Japan's non-residential uses solar power system is very small, the equipment capacity identified in 2012 alone the cumulative installed capacity of close to residential use. 

In addition, since April 2013, the above 10kW power purchase price from 42 yen / kWh down to 37.8 yen / kWh. Therefore, part of the solar power system stakeholders speculated that March 2013 will have a much larger number of devices made identified. The year 2012 finds that the amount of solar power generation in Japan may hit a historic record.
