Solar power in Japan has been expanding since the late 1990s. The country is a leading manufacturer of photovoltaics (PV) and a large installer of domestic PV systems with most of them grid connected.[1] Japan has an insolation of about 4.3 to 4.8 kWh/(m²·day).

Solar power has become an important national priority since the country's shift in policies toward renewable energy after the Fukushima Daiichi nuclear disaster in 2011.[2][3] Japan was the world's second largest market for solar PV growth in 2013 and 2014, adding a record 6.97 GW and 9.74 GW of nominal nameplate capacity, respectively. By the end of 2016, cumulative capacity reached 42,750 MW, the world's second largest solar PV installed capacity, behind China.[4] Overall installed capacity in 2016 was estimated to be sufficient to supply almost 5% of the nation's annual electricity demand.[4] '''Although solar power represents a significant and growing source of electricity generation in the country, hydroelectricity still had the largest share of renewable energy with 49.9 GW. This can be compared to the 33 GW of installed solar capacity in Japan after 2015.[5][6]'''

In December 2008, the Ministry of Economy, Trade and Industry announced a goal of 70% of new homes having solar power installed, and would be spending $145 million in the first quarter of 2009 to encourage home solar power.[7] The government enacted a feed-in tariff on November, 2009 that requires utilities to purchase excess solar power sent to the grid by homes and businesses and pay twice the standard electricity rate for that power.[8]

On June 18, 2012, a new feed-in tariff was approved, of 42 Yen/kWh. The tariff covers the first ten years of excess generation for systems less than 10 kW, and generation for twenty years for systems over 10 kW. It became effective July 1, 2012.[9] In April 2013, the FIT was reduced to 37.8 Yen/kWh.[10] The FIT was further reduced to 32 Yen/kWh in April 2014.[11]

In March 2016, a new feed-in tariff was approved. The Procurement Price Calculation Committee compiled and publicized recommendations concerning the FY 2016 purchase prices and the periods therefor. Respecting the recommendations, METI finalized the prices and periods therefor as below.

(1) Electricity generated by photovoltaic power for non-household customers (10 kW or more) was reduced from 27 yen/kWh to 24 yen/kWh.

(2) Electricity generated by photovoltaic power for household customers (10 kW or less) was reduced from 33 yen/kWh to 31 yen/kWh when generators are not required to have output control equipment installed. When generators are required to have output control equipment installed the price was reduced from 35 yen/kWh to 33 yen/kWh. [12]

The most recent FIT only concerns non-residential solar power plants. The new FIT will go from JPY21/kWh in 2017 to JPY18/kWh when the reduction starts affecting facilities that were certified in and after April of 2018.[13]

Targets Ambox current red.svg This article needs to be updated. In particular: New targets per post-Fukushima feed-in-tariffs, see the above section. Please update this article to reflect recent events or newly available information. (April 2017) The government set solar PV targets in 2004 and revised them in 2009:[14]

28 GW of solar PV capacity by 2020 53 GW of solar PV capacity by 2030 10% of total domestic primary energy demand met with solar PV by 2050 The targets set for 2020 were surpassed in 2014, and the target for 2030 is expected to be surpassed in 2017-2018.

New targets were adopted after 2011.

Japanese solar cell production (in GW) Total   Export    Domestic Solar manufacturing industry Japan is a leading manufacturer of photovoltaics. In other words, photovoltaic devices use semiconductors in order to generate electricity from the sunlight. [15]Solar companies of Japan include: Kyocera, Mitsubishi Electric, Mitsubishi Heavy Industries, Sanyo, Sharp Solar, Solar Frontier, and Toshiba.

Notable projects

The Solar Ark is a 315 meter wide, 37 meter tall educational platform about renewable energy

Komekurayama Solar Power Plant owned and operated by TEPCO in Kofu, Yamanashi Prefecture Main article: List of power stations in Japan The Solar Ark, built in 2002, is one of the largest solar buildings in the world. '''Between its scrap monocrystalline modules used to build this building, and then 500,000 kWh of energy it produces each year, it is very beneficial. [16] ''' After the shift away from a nuclear power-dependent energy policy in the wake of the Fukushima nuclear accident,[17] the first three solar plants by TEPCO were completed in 2011 and 2012, the Ukishima Solar Power Plant, 7 MW, the Ogishima Solar Power Plant, 13 MW, and the Komekurayama Solar Power Plant, 10 MW. The output of all three can be monitored on the internet.[18]

341 MW of photovoltaics are planned for the island of Hokkaido, and a total of 1,800 MW of photovoltaics projects have been approved for Japan, as of October 2012.[19]

Additional projects include the 70MW Kagoshima Nanatsujima Mega Solar Power Plant by Kyocera in Kagoshima Prefecture that went online in November 2013 and a 100 MW plant by Toshiba in Minami Soma, Fukushima Prefecture.[20][21]

A 77 MW photovoltaic power plant is planned for Tahara City, on the Atsumi Peninsula, and is expected to be completed in 2014.[22] A 200 MW plant is proposed for Tomakomai.[23]

'''Another recent project starting in 2017 will include a floating solar farm on the Yamakura Dam. This project will provide enough power for 5,000 households in Japan. It is said to be completed in 2018 and will be located on a reservoir in Japan's Chiba prefecture. [24] ''' It is expected that many new projects will be constructed, to take advantage of the new feed-in tariff.

Throughout the next several weeks I will be working to expand on the solar power in Japan article on wikipedia. There are lots of recent projects Japan is working on so I plan on researching the progress of those projects and keeping the readers up to date.
