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).
How much does a power plant cost in Japan?
While the median value for medium size power plants in Japan was 13,500 yen/kW (REI data), the US price for distributed inverters was 0.08 USD/W, which equates to 8,800 yen/kW (NREL, 2018a). Compared to distributed inverters, the unit price for inverters in Japan is approximately 50% higher.
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.
