Poland Grew Solar Power Fastest, 10 times as Much in 2025 as in 2020

Between 2020 and 2025, Poland grew its solar electricity 10 times over (1.96 TWh in 2020 to 19.5 TWh in 2025). Pakistan (8.9 times), Brazil (8.4 times) and Portugal (5.1 times) follow. 39 countries met the size tests.

Countries that generated at least 10 TWh in 2025, 79 in this data. Smaller grids are left out so a tiny system does not top every list. Needs at least 3 TWh of solar in 2025 and at least 0.3 TWh in 2020, so growth from almost nothing is not counted.
