Analysis
Japan recorded 14 terawatt-hours for annual change in primary energy from solar in 2025. That is the highest value across all 60 years on record.
The figure is up 3,144.7% on the previous year and up 27.3% over ten years.
Over the whole period, annual change in primary energy from solar in Japan peaked at 14 terawatt-hours in 2025 and was at its lowest, 0 terawatt-hours, in 1966.
That places Japan 7th out of 80 countries with data for 2025, putting it in the top 10%.
The series is highly variable year to year, so single readings are best treated with caution.
