Solar Power Generation by Country 2025

This chart compares the 20 largest solar electricity generators among countries with 2025 data in the report dataset accompanying Ember's Global Electricity Review 2026, published on 21 April 2026. It is a fixed report snapshot, not the continuously updated Yearly Electricity Data download. Countries without a 2025 observation in that snapshot cannot appear in this ranking.

The measure is electricity generated from solar photovoltaic and solar thermal sources, in terawatt-hours (TWh), not installed capacity. Ember includes distributed or rooftop solar where reported and estimates it for some countries. Its report methodology describes the 2025 figures as estimates of gross generation based on monthly changes and annual baselines, with dedicated annual sources in some cases. The estimates can be revised in later releases.

Countries are selected and ranked using the report's unrounded generation values. Chart values are rounded to one decimal using half-up rounding. Use the linked Supporting materials page to download the report CSV and read its methodology. The observation year is 2025; the report publication year is 2026.

China leads this snapshot at 1,174.9 TWh, followed by the United States at 388.8 TWh and India at 196.0 TWh. A volume ranking is different from a ranking by solar's percentage of a country's electricity mix, output per person or installed generating capacity. This chart alone does not explain why countries differ.
