Thanks, Greg. The FY 2012 rate was for between April "2012" and March 2013.
Thank you, Michael for your comment.
You are exactly right. One (peak point) is around 10 am and the other one is around 2-3 pm. I originally meant one peak in the morning and another peak occurs in the afternoon.
Thank you for pointing out! Junko
Thank you, Dennis.
Yes, this story is solely on the residential segment, excluding non-residential and utility segment.
The federal government also currently supports this emergency preparation by providing a subsidy of 1/3 of the battery installed cost.
Japan also tries to diversify renewable energy mix besides PV. The FIT rate for geothermal system below 15 MW is 42 yen/kWh (~$0.42/kWh) for 15 years and system over 15 MW is 27.3 yen/kWh (~$0.27/kWh) for 15 years.
Bob, Japan is just getting started for the large scale non-residential segment; however, Japan's residential market is one of the oldest (about 20 years old) and largest (+1.2 GW/yr in 2012) in the world. Japan's PV market has been built upon many many local, roof-top installers.
Japan has two key goals with the new FIT – expediting growth of large-scale non-residential systems: (1) support energy supply/diversification post Fukushima nuclear disaster and (2) support growth of domestic production (up to 2007 Japan was the world largest PV production country).
I agree that the roof-top is probably wiser choice specifically space-constraint market like Japan.
For residential systems, it should be from high 300 yen/W to low 400 yen/W ($3-$4/W when $1 = 100 yen conversion). The national government provides a upfront, capacity-based incentive, which pays 20 yen/W for system installed cost is lower than 410 yen/W while 15 yen/W for system installed cost is lower than 500 yen/W and greater than 410 yen/W.
