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 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 solar PV cost?

According to the latest studies from other research organizations, the global cost of solar PV (global weighted average unit cost) has fallen even further since, from 8.8 US cents1/kWh in 2017 to 5.7 US cents/kWh in the first half of 2019 (BNEF, 2019).

What is the unit price of inverters in Japan?

Compared to distributed inverters, the unit price for inverters in Japan is approximately 50% higher. However, the upper quartile value for inverter unit price in Japan is 9,800 yen/kW, close to the global standard. From the above, we will envision the following two scenarios for the unit price of inverters in 2030.

Are solar PV investment costs decreasing over time?

The findings of the study generally reconfirm the findings of the 2019 report; with the decline in costs for solar PV modules, mounting systems, and installation costs, investment costs for solar PV generation have been decreasing over time.

Is solar PV the cheapest option?

This study indicated that the cost of solar PV generation can potentially be reduced significantly in the lead-up to 2030, to around the 5 yen/kWh level. This is meaningful as it indicates that solar PV would be the cheapest option among newly constructed power plants.
