Analysis
Thailand recorded 9,990 terawatt-hours for solar energy generation vs. capacity in 2025. That is the highest value across all 55 years on record.
That represents a change of up 9.7% on the previous year and up 320.1% over ten years.
Over the whole period, solar energy generation vs. capacity in Thailand peaked at 9,990 terawatt-hours in 2025 and was at its lowest, 0 terawatt-hours, in 1971.
That places Thailand 29th out of 79 countries with data for 2025, putting it in the middle of the range.
The series is highly variable year to year, so single readings are best treated with caution.
