How much does solar PV cost in Japan?

Particularly noteworthy is that in the efficient scenario the generation cost was 13.1 yen per kilowatt-hour (/kWh), approaching the average power exchange electricity price. Based on the above cost structure analysis and findings from existing research, we estimated the generation cost for solar PV in Japan in 2030 based on several scenarios.

How much will solar PV cost in Japan in 2030?

Based on the above cost structure analysis and findings from existing research, we estimated the generation cost for solar PV in Japan in 2030 based on several scenarios. Our estimate forecasts that generation costs will drop significantly, to the 5-6 yen/kWh level (Fig. S-2).

How much does solar power cost per kWh?

The cost of solar power generation (per kWh) is rapidly declining on a global scale. The generation cost of solar photovoltaic (PV) (utility-scale solar, global weighted average unit cost) has plunged 73% between 2010 and 2017 to 8.5 US cents/kWh (IRENA, 2019).

Do you need a subscription to use solar energy in Japan?

A paid subscription is required for full access. In the fiscal year 2023, the FIT price of electricity that was generated from solar energy in Japan was set at ten Japanese yen per kilowatt hour, reaching a decade-low. The feed-in tariff (FIT) system is a national system under which the unit price of electricity is fixed by the country.

How long will a solar PV power plant operate in Japan?

In the case of a 30-year operating period, a solar PV power plant which commenced operation in 2030 will operate until 2059. At this time, it is likely that the scale of solar PV generation in Japan will be significantly larger. In this situation, it is possible that a frequent oversupply of electricity will occur during daytime hours.

How much will solar power cost in 2030?

Meanwhile, the government's Working Group on Generation Costs (2015) estimates the 2030 cost of solar PV (utility-scale) at 12.7-15.6 yen/kWh. As shown, there is large variance in the outlook and targets for solar power generation.
