Household solar power generation in Japan

The Japanese government is seeking to expand solar power by enacting subsidies and a (FIT). In December 2008, the 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. The government enacted a feed-in tariff in November 2009 that requires utilities to purchase excess solar power sent to the grid by homes. [pdf]

FAQS about Household solar power generation in Japan

What percentage of Japan's Energy is solar?

In 2022, solar energy accounted for 5.39% of Japan’s total energy mix and 9.91% of its electricity generation. In both cases, solar power in Japan holds the largest share of all renewable sources. This is a drastic contrast to even a decade ago when solar energy contributed less than 1% of the country’s energy.

Who makes solar power in Japan?

In line with the significant rise in installations and capacity, solar power accounted for 9.9% of Japan's national electricity generation in 2022, up from 0.3% in 2010. Japanese manufacturers and exporters of photovoltaics include Kyocera, Mitsubishi Electric, Mitsubishi Heavy Industries, Sanyo, Sharp Solar, Solar Frontier, and Toshiba.

What percentage of electricity is generated by renewables in Japan?

However, Japan’s percentage of electricity generated by renewables in total power generation is still low compared with those of other major nations, despite an increase from 10% in FY2011 to 20% in FY2020. Comparison of percentages of renewable energy in total power generation in major nations (Percentage of total generated power)

Is solar energy the future of Japan's Energy Strategy?

Solar energy in Japan is emerging as a cornerstone of Japan’s strategy to meet its ambitious long-term sustainability goals. The Sixth Strategic Energy Plan aims for carbon neutrality by 2050 with an interim goal of 36-38% of energy from renewables by 2030.

How much solar energy does Japan need in 2022?

This is a drastic contrast to even a decade ago when solar energy contributed less than 1% of the country’s energy. In total, solar energy in Japan grew from 11.05 TWh in 2010 to over 260 TWh in 2022. However, even with this shift, the country must dramatically increase its solar energy infrastructure to meet its 2030 and 2050 targets.

Why is solar power growing in Japan?

The steady growth of solar power in Japan is attributed to several factors, including the country’s focus on energy security, economic efficiency and environmental sustainability. Post-Fukushima, there was a national reevaluation of energy sources.

Japan s solar power generation utilization rate

In 2021, solar PV accounted for 9.3% of annual electricity generation, up about 1 percentage point from 8.5% the previous year, and variable renewables VRE (solar and wind) accounted for 10.2%. [pdf]
